An up-to-date firewall can help you protect your organization’s network while allowing legitimate business communication to be sent and received. It keeps bad actors out and can be used to keep employees away from insecure or non-work-related sites.

While a firewall provides excellent security and protection, it needs monitoring and management. Monitoring your own firewall is a time-consuming, intensive, and expensive task that requires security expertise and regular upgrades. Many organizations lack the internal expertise, time, and capital to monitor their own firewalls around-the-clock. For these companies, a managed firewall is an affordable, effective solution.

How a Managed Firewall Works

Managed Firewall Service in India

Managed Firewall Service in India

A managed firewall is a service that offers enhanced threat management. Security experts monitor your firewall remotely and can help mitigate any potential threats. To accomplish this, they study your network traffic and learn what normal traffic looks like for your business. When any unusual activity is detected, it can be quickly identified and addressed.

In addition, your provider will perform routine traffic analysis and send regular reports to you so you will have a clear sense of your network traffic patterns and how your managed services team is managing threats to your network.

Expertise Made Affordable by The Economy of Scale

The beauty of IT services like managed firewall is their ability to leverage economies of scale to offer companies the cybersecurity they need, at a price they can afford. In the past, your only option was to create an in-house security solution for your network, which you had to pay for through a capital expenditure.

Here are 3 ways a managed firewall can enhance your company’s operations:

1. Protect against Cyber Crime

Protect against Cyber Crime

Cyber crime is a growing concern for businesses and citizens alike. According to a recent cyber crime report published by research firm Cybersecurity Ventures, cyber attack rates are climbing faster than any other crime and will cost the global economy $6 trillion annually by 2021.

A business that falls prey to a cyber criminal will face serious losses and a tough road ahead. According to a 2017 report published by the Better Business Bureau, half of all businesses would lose their profitability within a month if their critical data was lost.

With a managed firewall, business owners can avoid or mitigate the risk of a cyber attack or breach.

2. Meet compliance requirements

As the threat level of cyber attacks continues to grow, so does the burden of compliance regulations. Existing regulations such as HIPAA, PCI DSS, and Sarbanes Oxley continue to evolve with ever stricter and more technical compliance requirements. New regulations such as GDPR add to the complexity.

A managed firewall service provider with compliance expertise can ensure your company meets these legal requirements, avoiding the heavy penalties associated with negligence.

3. Ease burden of monitoring

The burden of round-the-clock monitoring can be heavy for many SMBs. For example, if you have a small IT department with just one security expert, it’s not possible for your staff to continuously monitor your network.

Most business owners need to stay focused on their core business activities; they don’t have time to become IT security experts. And hiring enough staff for 24/7 monitoring may be too expensive. A managed firewall solution solves both of these problems.

Firewalls can protect your network against unauthorized access and intruders.

As enterprises expand its mission-critical networks with newer applications, many have begun to view network security technologies as the key to prevent intrusion and exposure of critical data. Without protection, companies can experience security breaches resulting in serious damages. The security system that all enterprises should seek to implement in such a situation is a firewall. Firewalls are certainly becoming a critical part of any secure network.

20 TOP MOST PROBLEMS IN FIREWALLS WHICH IMPACT BUSINESS

  1.  Failing to save the CONFIGURATION: 90% of the times we don’t save the configuration which gives the problem when we reboot the Firewall or Router.
  2. Configuration done by the Engg is not meeting the company policy
  3. Rules are not used still there in the ACL
  4. Duplicate Rules no documentation of the rules.
  5. Firewall connection exceeds as not taken in account eh VPN or SSL connections while making a DECISIONS or the Firewall is OLD
  6. Memory full issue there is bug in the rules or the configuration making firewall slow or reboots automatically.
  7. Firewall OS is older and new OS is not supported.
  8. Unwanted application are taking lot of bandwidth like video youtube etc. then bring down the productivity of the organisation.
  9. Link problem. The like is not stable and goes down or flaps too much.
  10.  NO QOS done for the rules and on the application.
  11. OSPF or BGP not configured properly.
  12. Poor VOIP quality which may be due to link flap or too much bandwidth taken by other applications
  13. Duplexing not done properly.
  14. Passwords are simple or easy to decode authentication is not upto the mark
  15. MS-SQL is open from the outside for the applications via server with just application authentication.
  16. Anti-spoofing not configured on the interfaces
  17. No logging is done for the system changes.
  18.  Any TCP or UDP packet can go out.
  19. Proxy services are not stopped
  20. Certification not configured on the firewall to have the ultimate Security.

The Last one is important and no one configures firewall for that (certification)

Every one is thinking that firewall is now matured and nothing is need more.

But after ransomware things have changed.

What is Firewall?

A firewall is a network security device located between your internal network and the wider Internet. A firewall monitors incoming and outgoing network traffic – blocking or allowing it based on a set of configurable rules.

Firewalls are a fundamental piece of security and typically form the first line of defense on a network. Acting as a filter against bad connections from the outside world.

A firewall works by comparing the data sent into or out of the network against a list of rules. Based on the results of the rule checking, the firewall will then either block or allow the connection.

How Does Firewall Work?

Introduction

A firewall is a system that provides network security by filtering incoming and outgoing network traffic based on a set of user-defined rules. In general, the purpose of a firewall is to reduce or eliminate the occurrence of unwanted network communications while allowing all legitimate communication to flow freely. In most server infrastructures, firewalls provide an essential layer of security that, combined with other measures, prevent attackers from accessing your servers in malicious ways.

This guide will discuss how firewalls work, with a focus on stateful software firewalls, such as iptables and FirewallD, as they relate to cloud servers. We’ll start with a brief explanation of TCP packets and the different types of firewalls. Then we’ll discuss a variety of topics that a relevant to stateful firewalls. Lastly, we will provide links to other tutorials that will help you set up a firewall on your own server.

TCP Network Packets

Before discussing the different types of firewalls, let’s take a quick look at what Transport Control Protocol (TCP) network traffic looks like.

TCP network traffic moves around a network in packets, which are containers that consist of a packet header—this contains control information such as source and destination addresses, and packet sequence information—and the data (also known as a payload). While the control information in each packet helps to ensure that its associated data gets delivered properly, the elements it contains also provides firewalls a variety of ways to match packets against firewall rules.

It is important to note that successfully receiving incoming TCP packets requires the receiver to send outgoing acknowledgment packets back to the sender. The combination of the control information in the incoming and outgoing packets can be used to determine the connection state (e.g. new, established, related) of between the sender and receiver.

Types of Firewalls

Let’s quickly discuss the three basic types of network firewalls: packet filtering (stateless), stateful, and application layer.

Packet filtering, or stateless, firewalls work by inspecting individual packets in isolation. As such, they are unaware of connection state and can only allow or deny packets based on individual packet headers.

Stateful firewalls are able to determine the connection state of packets, which makes them much more flexible than stateless firewalls. They work by collecting related packets until the connection state can be determined before any firewall rules are applied to the traffic.

Application firewalls go one step further by analyzing the data being transmitted, which allows network traffic to be matched against firewall rules that are specific to individual services or applications. These are also known as proxy-based firewalls.

In addition to firewall software, which is available on all modern operating systems, firewall functionality can also be provided by hardware devices, such as routers or firewall appliances. Again, our discussion will be focused on stateful software firewalls that run on the servers that they are intended to protect.

Firewall Rules

As mentioned above, network traffic that traverses a firewall is matched against rules to determine if it should be allowed through or not. An easy way to explain what firewall rules looks like is to show a few examples, so we’ll do that now.

Suppose you have a server with this list of firewall rules that apply to incoming traffic:

  1. Accept new and established incoming traffic to the public network interface on port 80 and 443 (HTTP and HTTPS web traffic)
  2. Drop incoming traffic from IP addresses of the non-technical employees in your office to port 22 (SSH)
  3. Accept new and established incoming traffic from your office IP range to the private network interface on port 22 (SSH)

Note that the first word in each of these examples is either “accept”, “reject”, or “drop”. This specifies the action that the firewall should do in the event that a piece of network traffic matches a rule. Accept means to allow the traffic through, reject means to block the traffic but reply with an “unreachable” error, and drop means to block the traffic and send no reply. The rest of each rule consists of the condition that each packet is matched against.

As it turns out, network traffic is matched against a list of firewall rules in a sequence, or chain, from first to last. More specifically, once a rule is matched, the associated action is applied to the network traffic in question. In our example, if an accounting employee attempted to establish an SSH connection to the server they would be rejected based on rule 2, before rule 3 is even checked. A system administrator, however, would be accepted because they would match only rule 3.

Default Policy

It is typical for a chain of firewall rules to not explicitly cover every possible condition. For this reason, firewall chains must always have a default policy specified, which consists only of an action (accept, reject, or drop).

Suppose the default policy for the example chain above was set to drop. If any computer outside of your office attempted to establish an SSH connection to the server, the traffic would be dropped because it does not match the conditions of any rules.

If the default policy were set to accept, anyone, except your own non-technical employees, would be able to establish a connection to any open service on your server. This would be an example of a very poorly configured firewall because it only keeps a subset of your employees out.

Incoming and Outgoing Traffic

As network traffic, from the perspective of a server, can be either incoming or outgoing, a firewall maintains a distinct set of rules for either case. Traffic that originates elsewhere, incoming traffic, is treated differently than outgoing traffic that the server sends. It is typical for a server to allow most outgoing traffic because the server is usually, to itself, trustworthy. Still, the outgoing rule set can be used to prevent unwanted communication in the case that a server is compromised by an attacker or a malicious executable.

In order to maximize the security benefits of a firewall, you should identify all of the ways you want other systems to interact with your server, create rules that explicitly allow them, then drop all other traffic. Keep in mind that the appropriate outgoing rules must be in place so that a server will allow itself to send outgoing acknowledgements to any appropriate incoming connections. Also, as a server typically needs to initiate its own outgoing traffic for various reasons—for example, downloading updates or connecting to a database—it is important to include those cases in your outgoing rule set as well.

Writing Outgoing Rules

Suppose our example firewall is set to drop outgoing traffic by default. This means our incoming accept rules would be useless without complementary outgoing rules.

To complement the example incoming firewall rules (1 and 3), from the Firewall Rules section, and allow proper communication on those addresses and ports to occur, we could use these outgoing firewall rules:

  1. Accept established outgoing traffic to the public network interface on port 80 and 443 (HTTP and HTTPS)
  2. Accept established outgoing traffic to the private network interface on port 22 (SSH)

Note that we don’t need to explicitly write a rule for incoming traffic that is dropped (incoming rule 2) because the server doesn’t need to establish or acknowledge that connection.

Firewall Software and Tools

Now that we’ve gone over how firewalls work, let’s take a look at common software packages that can help us set up an effective firewall. While there are many other firewall-related packages, these are effective and are the ones you will encounter the most.

Iptables

Iptables is a standard firewall included in most Linux distributions by default (a modern variant called nftables will begin to replace it). It is actually a front end to the kernel-level netfilter hooks that can manipulate the Linux network stack. It works by matching each packet that crosses the networking interface against a set of rules to decide what to do.

UFW

UFW, which stands for Uncomplicated Firewall, is an interface to iptables that is geared towards simplifying the process of configuring a firewall.

To learn more about using UFW, check out this tutorial: How To Setup a Firewall with UFW on an Ubuntu and Debian Cloud Server.

FirewallD

FirewallD is a complete firewall solution available by default on CentOS 7 servers. Incidentally, FirewallD uses iptables to configure netfilter.

To learn more about using FirewallD, check out this tutorial: How To Configure FirewallD to Protect Your CentOS 7 Server.

If you’re running CentOS 7 but prefer to use iptables, follow this tutorial: How To Migrate from FirewallD to Iptables on CentOS 7.

Fail2ban

Fail2ban is an intrusion prevention software that can automatically configure your firewall to block brute force login attempts and DDOS attacks.

Conclusion

Now that you understand how firewalls work, you should look into implementing a firewall that will improve your security of your server setup by using the tutorials above.

A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet. If you can’t start Windows Firewall or you are getting an error, use Microsoft free tool to diagnose and fix problems.

  • If you use a computer at home, the most effective and important first step you can take to help protect your computer is to turn on a firewall.
  • Windows 8, Windows 7, Windows Vista, and Windows XP SP2 or higher have a firewall built-in and turned on by default. (Note: Support for Windows XP ended in April 2014.)
  • If you have more than one computer connected in the home, or if you have a small-office network, it is important to protect every computer. You should have a hardware firewall (such as a router) to protect your network, but you should also use a software firewall on each computer to help prevent the spread of a virus in your network if one of the computers becomes infected.
  • If your computer is part of a business, school, or other organizational network, you should follow the policy established by the network administrator.

What is a firewall?

A firewall is a network security device located between your internal network and the wider Internet. A firewall monitors incoming and outgoing network traffic – blocking or allowing it based on a set of configurable rules.

Firewalls are a fundamental piece of security and typically form the first line of defence on a network. Acting as a filter against bad connections from the outside world.

A firewall works by comparing the data sent into or out of the network against a list of rules. Based on the results of the rule checking, the firewall will then either block or allow the connection.

How does a firewall work?

Firewalls work by inspecting data packets (small chunks of data) against an internal list of rules. Here are some of the more common ones:

  • IP addresses – filter out traffic from suspicious IPs
  • Domain names – block traffic from known malicious domains
  • Ports – deny traffic trying to enter through a certain port
  • Contents – block data packets containing certain keywords

A firewall scans the contents of the packet and then determines whether to let it through based on the rules in place. On a typical network setup, all connections to the Internet flow through the firewall. Meaning it inspects all inbound or outgoing packets.

How does firewall inspection work?

The process of inspection involves comparing a packet’s contents against the firewall’s set of rules. Depending on if the rule is setup as a blacklist or whitelist, it will react differently to a match.

  • A blacklist rule will block any packets which match the criteria.
  • A whitelist rule will block any packets which don’t match the criteria.

A firewall’s rules are highly configurable. Meaning you can make the packet inspection process unique to your security setup. Here are some examples of how you could use custom firewall rules:

  • Creating a whitelist for your own company IP. Preventing any outsiders from accessing what’s behind the firewall.
  • Making a blacklist for the IP of a known malicious file server. Stopping it from distributing malware onto your network.
  • Creating a whitelist for certain domain extensions (.com, .co.uk .edu e.t.c.) on outgoing traffic. Blocking staff from accessing potentially dangerous sites.

Why are firewalls important?

Firewalls are often compared to a lock on the door to your network. But it might be more accurate to say that a firewall is the door.

Without a firewall in place, any connection can flow freely in or out of your network. Including connections from known malicious sources. This means you could experience unauthorised access to networked files. Leading to a data breach, malware infection or worse.

You need a firewall to filter out the bulk of malicious connections. And there’s a lot of malicious connections. One study found that within 52 seconds of being online, servers were being probed by hackers. With an average rate of 757 connection attempts per hour.

Are firewalls hardware or software?

Firewalls can be either a hardware appliance or a piece of software which runs on a machine. So, the answer is both.

Not helpful, I know.

But the main difference between the two is this:

  • Software firewalls tend to protect the individual machine it’s installed upon, typically a laptop or PC
  • Hardware firewalls usually protect many machines or an entire network.

What types of firewall are there?

Circuit-level

Circuit level firewalls are a type of firewall that monitors transmission control protocol (TCP) handshaking. It ensures that the communication between packets is legitimate and not malicious.

Stateful inspection

A firewall with stateful inspection considers the state of current connections when filtering packets. This means that the firewall can block the packet in one case but allowed in another. Depending on the current state of the connection.

Unified threat management (UTM)

Whilst technically not a type of firewall, UTM is instead an advanced security appliance which combines the security functions of many different security appliances. One of these being a firewall. We have an article explaining everything you need to know about UTM if you wish to learn more.

What is a next-generation firewall?

A next-generation firewall (NGFW) contains all the normal defences that a traditional firewall has and more. The most common additions are intrusion prevention software and application control. But certain vendors have other bonus security features. NGFWs are also capable of deep packet inspection which enables more robust filters.

Intrusion prevention software monitors network activity to detect and stop vulnerability exploits from occurring. This is usually done by monitoring for breaches against the network policies in place.

Application control software sets up a hard filter for programs that can send or receive data over the Internet. This can either be done by blacklist (blocks any programs in the filter) or by whitelist (blocks any programs not in the filter).

What is deep packet inspection?

Deep Packet Inspection (DPI) is a type of packet inspection which analyses the full contents of a data packet. Instead of only information in a packet’s header (where it is coming from and going to).

This enables DPI to filter out malicious packets, such as viruses and trojans, with better accuracy. As rather than only looking at the sender and destination, the packet’s contents can be used in filters as well.

This allows DPI to uncover a broader range of security threats because it will discover packets with a malicious payload but an innocuous header.

Where did the name firewall come from?

A final piece of trivia: the name firewall originated from the real-world application of fire partitions used in buildings. These would be walls that were implemented into a building to act as a barrier to stop fire spreading from one room to another.

The similarity between a fire spreading through a building and a computer virus spreading through a network prompted the same name to be adopted for the network device.

A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications.

In computing, load balancing distributes workloads across multiple computing resources, such as computers, a computer cluster, network links, central processing units or disk drives. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource.

In computing, load balancing improves the distribution of workloads across multiple computing resources, such as computers, a computer cluster, network links, central processing units, or disk drives. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource. Using multiple components with load balancing instead of a single component may increase reliability and availability through redundancy. Load balancing usually involves dedicated software or hardware, such as a multilayer switch or a Domain Name System server process.

Load balancing differs from channel bonding in that load balancing divides traffic between network interfaces on a network socket (OSI model layer 4) basis, while channel bonding implies a division of traffic between physical interfaces at a lower level, either per packet (OSI model Layer 3) or on a data link (OSI model Layer 2) basis with a protocol like shortest path bridging.

Internet-based services

One of the most commonly used applications of load balancing is to provide a single Internet service from multiple servers, sometimes known as a server farm. Commonly load-balanced systems include popular web sites, large Internet Relay Chat networks, high-bandwidth File Transfer Protocol sites, Network News Transfer Protocol (NNTP) servers, Domain Name System (DNS) servers, and databases.

Round-robin DNS

An alternate method of load balancing, which does not require a dedicated software or hardware node, is called round robin DNS. In this technique, multiple IP addresses are associated with a single domain name; clients are given IP in round robin fashion. IP is assigned to clients with a short expiration so the client is more likely to use a different IP the next time they access the Internet service being requested.

DNS delegation

Another more effective technique for load-balancing using DNS is to delegate www.example.org as a sub-domain whose zone is served by each of the same servers that are serving the web site. This technique works particularly well where individual servers are spread geographically on the Internet. For example:

one.example.org A 192.0.2.1
two.example.org A 203.0.113.2
www.example.org NS one.example.org
www.example.org NS two.example.org

However, the zone file for www.example.org on each server is different such that each server resolves its own IP Address as the A-record.[2] On server one the zone file for www.example.org reports:

@ in a 192.0.2.1

On server two the same zone file contains:

@ in a 203.0.113.2

This way, when a server is down, its DNS will not respond and the web service does not receive any traffic. If the line to one server is congested, the unreliability of DNS ensures less HTTP traffic reaches that server. Furthermore, the quickest DNS response to the resolver is nearly always the one from the network’s closest server, ensuring geo-sensitive load-balancing[citation needed]. A short TTL on the A-record helps to ensure traffic is quickly diverted when a server goes down. Consideration must be given the possibility that this technique may cause individual clients to switch between individual servers in mid-session.

Client-side random load balancing

Another approach to load balancing is to deliver a list of server IPs to the client, and then to have client randomly select the IP from the list on each connection. This essentially relies on all clients generating similar loads, and the Law of Large Numbers[4] to achieve a reasonably flat load distribution across servers. It has been claimed that client-side random load balancing tends to provide better load distribution than round-robin DNS; this has been attributed to caching issues with round-robin DNS, that in case of large DNS caching servers, tend to skew the distribution for round-robin DNS, while client-side random selection remains unaffected regardless of DNS caching.

With this approach, the method of delivery of list of IPs to the client can vary, and may be implemented as a DNS list (delivered to all the clients without any round-robin), or via hardcoding it to the list. If a “smart client” is used, detecting that randomly selected server is down and connecting randomly again, it also provides fault tolerance.
Server-side load balancers

For Internet services, a server-side load balancer is usually a software program that is listening on the port where external clients connect to access services. The load balancer forwards requests to one of the “backend” servers, which usually replies to the load balancer. This allows the load balancer to reply to the client without the client ever knowing about the internal separation of functions. It also prevents clients from contacting back-end servers directly, which may have security benefits by hiding the structure of the internal network and preventing attacks on the kernel’s network stack or unrelated services running on other ports.

Some load balancers provide a mechanism for doing something special in the event that all backend servers are unavailable. This might include forwarding to a backup load balancer, or displaying a message regarding the outage.

It is also important that the load balancer itself does not become a single point of failure. Usually load balancers are implemented in high-availability pairs which may also replicate session persistence data if required by the specific application.[5] Scheduling algorithms

Numerous scheduling algorithms, also called load-balancing methods, are used by load balancers to determine which back-end server to send a request to. Simple algorithms include random choice, round robin, or least connections.[6] More sophisticated load balancers may take additional factors into account, such as a server’s reported load, least response times, up/down status (determined by a monitoring poll of some kind), number of active connections, geographic location, capabilities, or how much traffic it has recently been assigned.
Persistence

An important issue when operating a load-balanced service is how to handle information that must be kept across the multiple requests in a user’s session. If this information is stored locally on one backend server, then subsequent requests going to different backend servers would not be able to find it. This might be cached information that can be recomputed, in which case load-balancing a request to a different backend server just introduces a performance issue.[6]

Ideally the cluster of servers behind the load balancer should not be session-aware, so that if a client connects to any backend server at any time the user experience is unaffected. This is usually achieved with a shared database or an in-memory session database, for example Memcached.

One basic solution to the session data issue is to send all requests in a user session consistently to the same backend server. This is known as “persistence” or “stickiness”. A significant downside to this technique is its lack of automatic failover: if a backend server goes down, its per-session information becomes inaccessible, and any sessions depending on it are lost. The same problem is usually relevant to central database servers; even if web servers are “stateless” and not “sticky”, the central database is (see below).

Assignment to a particular server might be based on a username, client IP address, or be random. Because of changes of the client’s perceived address resulting from DHCP, network address translation, and web proxies this method may be unreliable. Random assignments must be remembered by the load balancer, which creates a burden on storage. If the load balancer is replaced or fails, this information may be lost, and assignments may need to be deleted after a timeout period or during periods of high load to avoid exceeding the space available for the assignment table. The random assignment method also requires that clients maintain some state, which can be a problem, for example when a web browser has disabled storage of cookies. Sophisticated load balancers use multiple persistence techniques to avoid some of the shortcomings of any one method.

Another solution is to keep the per-session data in a database. Generally this is bad for performance because it increases the load on the database: the database is best used to store information less transient than per-session data. To prevent a database from becoming a single point of failure, and to improve scalability, the database is often replicated across multiple machines, and load balancing is used to spread the query load across those replicas. Microsoft’s ASP.net State Server technology is an example of a session database. All servers in a web farm store their session data on State Server and any server in the farm can retrieve the data.

In the very common case where the client is a web browser, a simple but efficient approach is to store the per-session data in the browser itself. One way to achieve this is to use a browser cookie, suitably time-stamped and encrypted. Another is URL rewriting. Storing session data on the client is generally the preferred solution: then the load balancer is free to pick any backend server to handle a request. However, this method of state-data handling is poorly suited to some complex business logic scenarios, where session state payload is big and recomputing it with every request on a server is not feasible. URL rewriting has major security issues, because the end-user can easily alter the submitted URL and thus change session streams.

Yet another solution to storing persistent data is to associate a name with each block of data, and use a distributed hash table to pseudo-randomly assign that name to one of the available servers, and then store that block of data in the assigned server.

Load balancer features

Hardware and software load balancers may have a variety of special features. The fundamental feature of a load balancer is to be able to distribute incoming requests over a number of backend servers in the cluster according to a scheduling algorithm. Most of the following features are vendor specific:

Asymmetric load

A ratio can be manually assigned to cause some backend servers to get a greater share of the workload than others. This is sometimes used as a crude way to account for some servers having more capacity than others and may not always work as desired.
Priority activation
When the number of available servers drops below a certain number, or load gets too high, standby servers can be brought online.

TLS Offload and Acceleration

TLS (or its predecessor SSL) acceleration is a technique of offloading cryptographic protocol calculations onto a specialized hardware. Depending on the workload, processing the encryption and authentication requirements of an TLS request can become a major part of the demand on the Web Server’s CPU; as the demand increases, users will see slower response times, as the TLS overhead is distributed among Web servers. To remove this demand on Web servers, a balancer can terminate TLS connections, passing HTTPS requests as HTTP requests to the Web servers. If the balancer itself is not overloaded, this does not noticeably degrade the performance perceived by end users. The downside of this approach is that all of the TLS processing is concentrated on a single device (the balancer) which can become a new bottleneck. Some load balancer appliances include specialized hardware to process TLS. Instead of upgrading the load balancer, which is quite expensive dedicated hardware, it may be cheaper to forgo TLS offload and add a few Web servers. Also, some server vendors such as Oracle/Sun now incorporate cryptographic acceleration hardware into their CPUs such as the T2000. F5 Networks incorporates a dedicated TLS acceleration hardware card in their local traffic manager (LTM) which is used for encrypting and decrypting TLS traffic. One clear benefit to TLS offloading in the balancer is that it enables it to do balancing or content switching based on data in the HTTPS request.

Distributed Denial of Service (DDoS) attack protection

Load balancers can provide features such as SYN cookies and delayed-binding (the back-end servers don’t see the client until it finishes its TCP handshake) to mitigate SYN flood attacks and generally offload work from the servers to a more efficient platform.

HTTP compression

HTTP compression reduces the amount of data to be transferred for HTTP objects by utilising gzip compression available in all modern web browsers. The larger the response and the further away the client is, the more this feature can improve response times. The trade-off is that this feature puts additional CPU demand on the load balancer and could be done by web servers instead.

TCP offload

Different vendors use different terms for this, but the idea is that normally each HTTP request from each client is a different TCP connection. This feature utilises HTTP/1.1 to consolidate multiple HTTP requests from multiple clients into a single TCP socket to the back-end servers.

TCP buffering

The load balancer can buffer responses from the server and spoon-feed the data out to slow clients, allowing the web server to free a thread for other tasks faster than it would if it had to send the entire request to the client directly.

Direct Server Return

An option for asymmetrical load distribution, where request and reply have different network paths.

Health checking

The balancer polls servers for application layer health and removes failed servers from the pool.

HTTP caching

The balancer stores static content so that some requests can be handled without contacting the servers.

Content filtering

Some balancers can arbitrarily modify traffic on the way through.

HTTP security

Some balancers can hide HTTP error pages, remove server identification headers from HTTP responses, and encrypt cookies so that end users cannot manipulate them.

Priority queuing

Also known as rate shaping, the ability to give different priority to different traffic.

Content-aware switching

Most load balancers can send requests to different servers based on the URL being requested, assuming the request is not encrypted (HTTP) or if it is encrypted (via HTTPS) that the HTTPS request is terminated (decrypted) at the load balancer.

Client authentication

Authenticate users against a variety of authentication sources before allowing them access to a website.

Programmatic traffic manipulation

At least one balancer allows the use of a scripting language to allow custom balancing methods, arbitrary traffic manipulations, and more.

Firewall

Firewalls can prevent direct connections to backend servers, for network security reasons.

Intrusion prevention system

Intrusion prevention systems offer application layer security in addition to network/transport layer offered by firewall security.

Use in telecommunications

Load balancing can be useful in applications with redundant communications links. For example, a company may have multiple Internet connections ensuring network access if one of the connections fails. A failover arrangement would mean that one link is designated for normal use, while the second link is used only if the primary link fails.

Using load balancing, both links can be in use all the time. A device or program monitors the availability of all links and selects the path for sending packets. The use of multiple links simultaneously increases the available bandwidth.

Shortest Path Bridging

The IEEE approved the IEEE 802.1aq standard May 2012, also known and documented in most books as Shortest Path Bridging (SPB). SPB allows all links to be active through multiple equal cost paths, provides faster convergence times to reduce down time, and simplifies the use of load balancing in mesh network topologies (partially connected and/or fully connected) by allowing traffic to load share across all paths of a network.[8][9] SPB is designed to virtually eliminate human error during configuration and preserves the plug-and-play nature that established Ethernet as the de facto protocol at Layer 2.

Routing

Many telecommunications companies have multiple routes through their networks or to external networks. They use sophisticated load balancing to shift traffic from one path to another to avoid network congestion on any particular link, and sometimes to minimize the cost of transit across external networks or improve network reliability.

Another way of using load balancing is in network monitoring activities. Load balancers can be used to split huge data flows into several sub-flows and use several network analyzers, each reading a part of the original data. This is very useful for monitoring fast networks like 10GbE or STM64, where complex processing of the data may not be possible at wire speed.

Use in data center networks

Load balancing is widely used in data center networks to distribute traffic across many existing paths between any two servers.[12] It allows more efficient use of network bandwidth and reduces provisioning costs. In general, load balancing in datacenter networks can be classified as either static or dynamic. Static load balancing distributes traffic by computing a hash of the source and destination addresses and port numbers of traffic flows and using it to determine how flows are assigned to one of the existing paths. Dynamic load balancing assigns traffic flows to paths by monitoring bandwidth utilization of different paths. Dynamic assignment can also be proactive or reactive. In the former case, the assignment is fixed once made, while in the latter the network logic keeps monitoring available paths and shifts flows across them as network utilization changes (with arrival of new flows or completion of existing ones). A comprehensive overview of load balancing in datacenter networks has been made available.

Relationship to fail overs

Load balancing is often used to implement failover—the continuation of a service after the failure of one or more of its components. The components are monitored continually (e.g., web servers may be monitored by fetching known pages), and when one becomes non-responsive, the load balancer is informed and no longer sends traffic to it. When a component comes back online, the load balancer begins to route traffic to it again. For this to work, there must be at least one component in excess of the service’s capacity (N+1 redundancy). This can be much less expensive and more flexible than failover approaches where each single live component is paired with a single backup component that takes over in the event of a failure (dual modular redundancy). Some types of RAID systems can also utilize hot spare for a similar effect.

Top Load Balancer Provider Company in India

Load balancing refers to spreading a service load among multiple server systems. A hardware load balancer or software-based load balancing tool can ensure maximum service availability by offering network traffic distribution services.

For example, if your business has a primary business domain (e.g., www.yourbusiness.com), you want your site available to your current customers and your potential customers 100 percent of the time. Comparing the top server load balancers (SLBs) and effectively utilizing their load-balancing capabilities will help provide this level of availability.

When technical folks discuss load balancing, they generally mean hardware load balancer devices dedicated to the task of balancing network traffic loads. A hardware load balancer is a server computer with a very specialized operating system tuned to manage network traffic using user-created rules.

From Load Balancers to Application Delivery Controllers

While these hardware load balancer devices have since evolved into what are now called application delivery controllers (ADC), load balancing remains at the heart of an ADC. Enterprises and hosting companies rely on load-balancing and ADC devices to distribute traffic to create highly available services.

In addition to providing simple distributed service to multiple servers, load balancers can help prevent denial-of-service attacks, allow legitimate users uninterrupted access to services, protect against single point of failure outages and prevent traffic bottlenecks to systems.

Today we’ll highlight a handful of the leading hardware load balancers as well as several cloud and software-based load balancer options.
