Firewall Checklist

Firewall Hardening Checklist

This checklist should be used to audit a firewall. This checklist does not provide vendor specific security considerations but rather attempts to provide a generic listing of security considerations to be used when auditing a firewall.Only technical aspects of security are addressed in this checklist. Manual elements like physical protection for the firewall server is not considered.

Prior to using this checklist the following elements should be considered:

  • Operating system: This checklist only defines the security items relating the firewall software and not to any security elements of the operating system.
  • Port restrictions: A listing of ports to be restricted are highlighted in this checklist.However, prior to recommending that the ports be restricted, the auditor should ensure that the service associated with that port is not used by the business e.g.remote access via telnet. Where such situations exist this checklist attempts to provide alternate security options if the service is needed e.g. use SSH instead of Telnet.
  • Modems within the internal network: Modems within the internal network are the biggest threat to subvert a firewall and thus the auditor should ensure that there of 6are no modems within the internal network. It is senseless performing an audition the firewall when an even bigger threat exists via the modem. The auditor should perform war dialing to identify any modems within the internal network with tools like phone sweeper.
  • Application level firewalls: The inherent nature of application level firewalls require that the operating system be as secure as possible due to the close binding of these two components. Thus, the auditor should ensure that the security on the operating system is secure before evaluating the security offered by the application level firewall.
  • De fence in depth: It must be recognized that the firewall implementation is a notan end to itself to provide security. Thus, it is vital that the auditor evaluate the security of the other components like IDS, operating systems, web applications,IIS/Apache, routers and databases. Some organizations have opted for firewall network appliances, which are firewalls loaded onto operating systems which have their security already pre configured. In such instances, the auditor need only review the security of the firewall configuration instead of the operating system as well.
  • Rulesets: This checklist provides a listing of best practice rule sets to be applied.However, the organizational requirements may not need all of the rule sets. Fore.g. where an organization has a need to allow access via the internet to critical servers, the rule sets wound not include a deny rule to that internal IP address forthe critical server. Instead it may provide for allow access to HTTP 80 to the critical IP and deny all other traffic to the critical IP. It must be noted that some elements of the recommended rule sets have to be applied irrespective of business requirements e.g. blocking private addresses (RFC1918), illegal addresses, standard unroutables, reserved addresses, etc.
  • Laptop users: Most organizations use mobile laptops for telecommuting and on the road sales, etc. This provides a further vulnerability even if the organization operates a VPN. The hacker could easily gain access to the laptop when it is connected to the internet and download tools to the laptop that can become a problem when the laptop is again connected to the corporate network. In a VPN situation, the hacker with access to the remote station once the tunnel is connected, can access the corporate network. In such a circumstance, it is important for the auditor to determine if laptop usage occurs and to evaluate whether personal firewalls are installed on these laptops prior to usage. This checklist provides a generic set of considerations for personal firewalls, but it does not provide any product specific security recommendations.

Checklist

 

No. Security Elements
1. Review the rulesets to ensure that they follow the order as follows:
•   anti-spoofing filters (blocked private addresses, internal addresses
appearing from the outside)
•   User permit rules (e.g. allow HTTP to public webserver)
•   Management permit rules (e.g. SNMP traps to network
management server)
•   Noise drops (e.g. discard OSPF and HSRP chatter)
•   Deny and Alert (alert systems administrator about traffic that is
suspicious)
•   Deny and log (log remaining traffic for analysis)
Firewalls operate on a first match basis, thus the above structure is important
to ensure that suspicious traffic is kept out instead of inadvertently allowing
them in by not following the proper order.

 

  1. Application based firewall
    Ensure that the administrators monitor any attempts to violate the security policy using the audit logs generated by the application level firewall. Alternatively some application level firewalls provide the functionality to log to intrusion detection systems. In such a circumstance ensure that the correct host, which is hosting the IDS, is defined in the application level firewall. Ensure that there is a process to update the application level firewall’s vulnerabilities checked to the most current vulnerabilities.Ensure that there is a process to update the software with the latest attack signatures.In the event of the signatures being downloaded from the vendors’ site, ensure that it is a trusted site.

    In the event of the signature being e-mailed to the systems administrator, ensure that digital signatures are used to verify the vendor and that the information transmitted has not been modified en-route.

 

The following commands should be blocked for SMTP at the application level firewall:

 

  • EXPN (expand)

 

  • VRFY (verify)

 

  • DEBUG

 

  • WIZARD

The following command should be blocked for FTP:

  • PUT

 

Review the denied URL’s and ensure that they are appropriate for e.g. any URL’s to hacker sites should be blocked. In some instances organisations may want to block access to x-rated sites or other harmful sites. As such they would subscribe to sites, which maintain listings of such harmful sites. Ensure that the URL’s to deny are updated as released by the sites that warn of harmful sites.

 

Ensure that only authorised users are authenticated by the application level firewall.

 

  1. Stateful inspection

 

Review the state tables to ensure that appropriate rules are set up in terms of source and destination IP’s, source and destination ports and timeouts. Ensure that the timeouts are appropriate so as not to give the hacker too much time to launch a successful attack.

 

For URL’s

 

  • If a URL filtering server is used, ensure that it is appropriately defined in the firewall software. If the filtering server is external to the organisation ensure that it is a trusted source.

 

  • If the URL is from a file, ensure that there is adequate protection for this file to ensure no unauthorised modifications.

 

Ensure that specific traffic containing scripts; ActiveX and java are striped prior to being allowed into the internal network.

 

If filtering on MAC addresses is allowed, review the filters to ensure that it is restricted to the appropriate MAC’s as defined in the security policy.

 

  1. Logging
    Ensure that logging is enabled and that the logs are reviewed to identify any potential patterns that could indicate an attack.

 

  1. Patches and updates
    Ensure that the latest patches and updates relating to your firewall product is tested and installed.
    If patches and updates are automatically downloaded from the vendors’ websites, ensure that the update is received from a trusted site.

 

In the event that patches and updates are e-mailed to the systems
administrator ensure that digital signatures are used to verify the vendor and
ensure that the information has not been modified en-route.
6. Location – DMZ
Ensure that there are two firewalls – one to connect the web server to the
internet and the other to connect the web server to the internal network.
In the event of two firewalls ensure that it is of different types and that dual
NIC’s are used. This would increase security since a hacker would need to
have knowledge of the strengths, weaknesses and bugs of both firewalls.
The rulesets for both firewalls would vary based on their location e.g. between
web server and the internet and between web server and the internal network.
7. Vulnerability assessments/ Testing
Ascertain if there is a procedure to test for open ports using nmap and whether
unnecessary ports are closed.
Ensure that there is a procedure to test the rulesets when established or
changed so as not to create a denial of service on the organisation or allow
any weaknesses to continue undetected.
8. Compliance with security policy
Ensure that the ruleset complies with the organisation security policy.
9. Ensure that the following spoofed, private (RFC 1918) and illegal addresses
are blocked:
Standard unroutables
• 255.255.255.255
• 127.0.0.0
Private (RFC 1918) addresses
• 10.0.0.0 – 10.255.255.255
• 172.16.0.0 – 172.31.255.255
• 192.168.0.0 – 192.168.255.255
Reserved addresses
• 240.0.0.0
Illegal addresses
• 0.0.0.0
UDP echo
ICMP broadcast (RFC 2644)
Ensure that traffic from the above addresses is not transmitted by the
interface.
10. Ensure that loose source routing and strict source routing (lsrsr & ssrr) are
blocked and logged by the firewall.
11. Port restrictions
The following ports should blocked:
Service Port Type Port Number
DNS Zone Transfers TCP 53
TFTP Daemon UDP 69
Link TCP 87
SUN RPC TCP & UDP 111
BSD UNIX TCP 512 – 514
LPD TCP 515
UUCPD TCP 540
Open Windows TCP & UDP 2000
NFS TCP & UDP 2049
X Windows TCP & UDP 6000 – 6255
Small services TCP & UDP 20 and below

HTTP ports

 

  1. Remote access
    If remote access is to be used, ensure that the SSH protocol (port 22) is used instead of Telnet.

 

  1. File Transfers
    If FTP is a requirement, ensure that the server, which supports FTP, is placed in a different subnet than the internal protected network.

 

  1. Mail Traffic
    Ascertain which protocol is used for mail and ensure that there is a rule to block incoming mail traffic except to internal mail.

 

  1. ICMP (ICMP 8, 11, 3)
    Ensure that there is a rule blocking ICMP echo requests and replies.
    Ensure that there is a rule blocking outgoing time exceeded and unreachable messages.

 

  1. IP Readdressing/IP Masquerading
    Ensure that the firewall rules have the readdressing option enabled such that internal IP addresses are not displayed to the external untrusted networks.

 

  1. Zone Transfers
    If the firewall is stateful, ensure packet filtering for UDP/TCP 53. IP packets for UDP 53 from the Internet are limited to authorised replies from the internal network. If the packet were not replying to a request from the internal DNS server, the firewall would deny it. The firewall is also denying IP packets for TCP 53 on the internal DNS server, besides those from authorised external secondary DNS servers, to prevent unauthorised zone transfers.

 

  1. Egress Filtering
    Ensure that there is a rule specifying that only traffic originating from IP’s within the internal network be allowed. Traffic with IP’s other than from the Internal network are to be dropped.
    Ensure that any traffic originating from IP’s other than from the internal network are logged.
  2. Critical servers
    Ensure that there is a deny rule for traffic destined to critical internal addresses from external sources. This rule is based on the organisational requirements, since some organisations may allow traffic via a web application to be routed via a DMZ.

 

  1. Personal firewalls
    Ensure that laptop users are given appropriate training regarding the threats, types of elements blocked by the firewall and guidelines for operation of the personal firewall. This element is essential, since often times personal firewalls rely on user prompt to respond to attacks e.g. whether to accept/deny a request from a specific address.
    Review the security settings of the personal firewall to ensure that it restricts access to specific ports, protects against known attacks, and that there is adequate logging and user alerts in the event of an intrusion.
    Ensure that there is a procedure to update the software for any new attacks that become known.
    Alternatively most tools provide the option of transferring automatic updates via the internet. In such instances ensure that updates are received from trusted sites.
  1. Distributed firewalls Ensure that the security policy is consistently distributed to all hosts especially when there are changes to the policy. Ensure that there are adequate controls to ensure the integrity of the policy during transfer, e.g. IPSec to encrypt the policy when in transfer. Ensure that there are adequate controls to authenticate the appropriate host. Again IPSec can be used for authentication with cryptographic certificates.

 

  1. Stealth Firewalls Ensure that default users and passwords are reset. Ensure that the firewall is appropriately configured to know which hosts are on which interface. Review the firewall access control lists to ensure that the appropriate traffic is routed to the appropriate segments. A stealth firewall does not have a presence on the network it is protecting and it makes it more difficult for the hacker to determine which firewall product is being used and their versions and to ascertain the topology of the network.
  1. Ensure that ACK bit monitoring is established to ensure that a remote system cannot initiate a TCP connection, but can only respond to packets sent to it.
  2. Continued availability of Firewalls: Ensure that there is a hot standby for the primary firewall.

Gandcrab ransomware vs. the world

GandCrab is one form of ransomware that has spread rapidly in recent years.

Ransomware has become one of the most serious cyberthreats facing organisations today. Regardless of how large or small your business is, hackers are targeting the data living on your computer systems. If you are not properly protected, then your reputation and profitability are at risk.

In a typical ransomware attack, the cybercriminal infects an operating system with a piece of malware that encrypts the data stored on it. This essentially locks you out of the computer;  the screen usually displays a message indicating that you are the victim of an attack.

No honour among thieves

When files are locked as the result of a ransomware attack, the hacker may offer to decode all data in exchange for a payment through a credit card or cryptocurrency account. However, submitting a ransom payment does not guarantee that your computer will be cleansed of the malware. In fact, most experts suggest you not make a payment because more times than not they bad guy doesn’t bother to provide a functional decryptor afterwards.

GandCrab is one form of ransomware that has spread rapidly in recent years.

The evolution of GandCrab

The GandCrab ransomware was developed by a team of cybercriminals and actually continues to evolve. To date, there have been five different versions of the malware found on the open internet. As each iteration is analysed and neutralised by technical experts, the hackers find new ways to exploit security holes.

In most cases, a GandCrab attack begins with a phishing attempt or other form of social engineering. For example, you might receive an email that contains a suspicious attachment or URL link. Often the message pretends to be from a legitimate source, like a credit card company, telling you that there is an issue with your account.

If you click on the link or open the attachment, the GandCrab virus loads onto your computer and begins scanning the local hard drive as well as any connected network drives. The malware encrypts every file it finds using a special format that cannot be easily cracked.

If your computer or network is infected by GandCrab, the first thing to do is determine what version of the malware you have by looking at the file extensions that appear on your computer. Version 1 uses .gdcb, versions 2 and 3 use .crab, version 4 uses .krab, and version 5 uses a randomised string of five letters.

How free decryptors work

While cybercriminals continue to develop GandCrab, there is a major effort underway to help victims of this ransomware attack. Cybersecurity specialists have teamed up to build and test decryptor tools, which they have begun to release as free downloads. The tool runs an algorithm against your hard drive to find affected files and convert them back to their original state.

As of today, there are decryptor tools available for versions 1 through 5 of GandCrab. If you need to use one to recover from an attack, be sure to obtain it through a legitimate source, such as a local government or law enforcement agency. Be wary of any GandCrab decryptors that show up on third-party websites, as these may actually be new viruses in disguise.

Moving forward, the ring of criminals behind GandCrab is expected to continue pushing new versions of the malware into the wild. With data being the most valuable resource on the web, they have turned the virus into a mirror image of the legitimate industry known as Software as a Service (SaaS) – they call itRansomware-as-a-Service (RaaS). The question is whether the decryptor tools will be able to keep up.

Protecting against attacks

If you are part of a business that relies on the internet for day-to-day operations, then it is critical to take measures to protect against cyberattacks like GandCrab. This is especially true if your data and systems interact with customers on the open internet.

Server security

The first step to secure your infrastructure and software is to audit your hosting provider. While there are good free hosts to be found, you have to sift through a lot of detritus to find them. Free or very low cost web hosts often use outdated security software on their servers and tend to pay more attention to splashing banner ads and upsells across your screen than securing their service.

Network contamination

Another major risk with the GandCrab malware is the potential for it to spread from one computer or server to another within the same local network. For example, if one user opens a dangerous attachment, it could cause a ripple effect across the entire organisation.

To keep your network safe, IT security officers need a plan in place for when malware is detected. The affected computer should be disconnected from the network immediately so that it can be diagnosed and repaired. There are many smart tools on the market today, including firewalls and intrusion detectors, to alert you the moment an issue occurs.

Nothing guarantees you won’t be bitten by Gandcrab except never using the internet. Not a preferred choice for many people. In order to have the best chance of avoiding this malware, there are a couple of points to make. The first is that everyone in your organisation needs to be educated and trained on the potential risks.

Secondly, given the rise in popularity of telecommuting, all employees should be required to use a virtual private network (VPN) any time they connect to internal company resources from a remote location (like home). Estimates say that one out of four people already use this data encryption tool, thanks to the fits it gives hackers, and use is expected to continue to rise.

Final thoughts

The GandCrab form of ransomware represents a significant risk to companies across the globe. If you choose to not properly protect yourself, there is more than a small chance you could lose access to all of the critical data on your local hard drive in an instant.

Fortunately, cybersecurity experts are building decryptor tools to battle against the criminals who designed GandCrab. These tools represent the best chance you have of eliminating a ransomware virus that’s already onboard and returning your system to a working state. Having to pay a large ransom to hackers to recover your encrypted files should be an absolute last resort.

Sizmek reviews account breach that enable attackers to modify existing ads and offers

  • The credential of the affected user account is being sold on the dark web for a price starting from $800.
  • Following the discovery, Sizmek has forced a password reset on all internal employee accounts.

Sizmek, an American online advertising platform is investigating a security incident in which hackers have gained access to one of the firm’s user account. The credential of the affected user account is being sold on the dark web for a price starting from $800.

What is the matter – Security research Brian Krebs discovered that the compromised account has been put up for sale on a Russian-language cybercrime forum. The account can allow the attackers to modify ads and analytics of big-name advertisers such as Gannett and Fox Broadcasting. The bidding of the stolen account starts at $800.

What is the impact – If threat actors buy access to these type of accounts, they can use it as a platform to add new users to the ad system and infect both the existing ads and offers. They can do this by injecting malicious scripts into the HTML code of ads that run on popular sites.

Citing further on threat actors’ nefarious activities, Kreb said, “They could hijack referral commissions destined for others and otherwise siphon ad profits from the system.”

George Pappachen, Sizmek’s general counsel, confirmed the breach and said that the account that is being resold on the dark web is a regular user account for Sizmek Advertising Suite (SAS).

“Or someone who is looking to sabotage our systems in a bigger way or allow malicious code to enter our systems,” George Pappachen, added.

What actions were taken – Following the discovery of the breach, Sizmek has forced a password reset on all internal employee accounts. In addition, the company is also working on deleting details of ex-employees, partners and vendors whose accounts may have been hijacked, from the SAS user database.

“We’re now doing some level of screening to see if there’s been any kind of intrusion we can detect. It seemed like [the screenshots were accounts from] past employees. I think there were even a couple of vendors that had access to the system previously,” Pappachen explained.

The company performed an extensive review in order to confirm that no unauthorized logins or accounts appeared in its systems. It is also monitoring for signals of irregular or unusual activities its platforms, Computer Business Review reported.

In general, a computer appliance is a computing device with a specific function and limited configuration ability, and a software appliance is a set of computer programs that might be combined with just enough operating system (JeOS) for it to run optimally on industry standard computer hardware or in a virtual machine.

A firewall appliance is a combination of a firewall software and an operating system that is purposely built to run a firewall system on a dedicated hardware or virtual machine. These include:

  • embedded firewalls: very limited-capability programs running on a low-power CPU system,
  • software-based firewall appliances: a system that can be run in independent hardware or in a virtualised environment as a virtual appliance
  • hardware-based firewall appliances: a firewall appliance that runs on a hardware specifically built to install as a network device, providing enough network interfaces and CPU to serve a wide range of purposes. From protecting a small network (a few network ports and few megabits per second throughput) to protecting an enterprise-level network (tens of network ports and gigabits per second throughput).
