Firewall Devices

Hardware firewalls come in a variety of types. There are commercially available systems that can cost thousands of dollars and are used by network administrators to control any size network. The most commonly available routers for general use are the types that connect to the average Small Office/Home Office (SOHO) network. They are small, easily configurable routers which contain firmware that allow for simple user configuration. They are specifically intended for SOHO use with DSL or cable modem connections. Most have a wireless capability installed as a feature on the router which allows the use of a laptop, or other device, anywhere within the range of the wireless router. Range from which a device can connect through the wireless function depends greatly on the make and model of the firewall. Routers also allow the investigator to distribute their broadband Internet connection between multiple computers. Putting together a SOHO network allows your investigative team to back up computer’s files on networked computers or storage devices in case an infected machine needs to be restored. Additionally, routers often have features that can be of potential use to the online investigator such as logging

The logging feature can assist the investigator in the identification of attempted, or successful, intrusions into their investigative system or network. The logs can also identify when investigative systems accessed the Internet and potentially where on the Internet the systems went. Each router and its configuration are different. Be sure to read the manufacturers’ manual to identify individual device features. At a minimum, the following common steps should be considered for router security:

1. Enable encryption: Current SOHO routers generally have Wired Equivelent Privacy (WEP) (an older hackable encryption system), Wi-Fi Protected Access (WPA) preferable, or WPA2 encryption. Ensure you turn on the encryption and use a strong password/passkey; otherwise, anyone with a wireless card could connect to your wireless access. If available, choose WPA-PSK (pre-shared key) and use a strong password/key.

2. Change the service set identifier (SSID)/disable broadcast: If you enable the wireless function, the default SSID (or wireless name for your access point) for your router needs to be changed to something unique to your system and does not identify the organization. The default SSID name makes it easier for hackers to identify and exploit your system. Disable the SSID broadcast so it cannot be seen. This will make your system stealthier and harder to discover. Simply turning off this function can prevent attack issues from the wireless feature.

3. Remote management: Turn off remote management. Sometimes called Wide Area Network (WAN) Management. This feature lets you change the router’s settings from the Internet. It’s an excessive risk and one that does not need to be taken.

4. Change the access password to your router: The default password for your router can probably be found on the Internet. Select a strong password of at least eight characters, using a combination of letters, numbers, and symbols. The password selected should not be a word easily found in the dictionary.

5. Disable Universal Plug and Play on the router.

6. Media Access Control (MAC): A good security option is MAC addressing. This ties hardware device addresses for each computer to a specific network subnet address (as assigned by your router) associated with your machine in order to validate the devices. It prevents unauthorized access to your network by unknown hardware.

7. Ping: Uncheck any options that allow the router to respond to a ping command from the Internet. No need to let anyone know your router is online.

Default Passwords

Most hackers know the default passwords for commonly sold routers and it has become a known exploit. Those that don’t know them can find them on websites, such as Router passwords.com and just look them up. A strong password is at least 8–12 characters, including letters, numbers, and symbols. The longer the password the better! Do not use words found in the dictionary or common names. These can make a brute force attack to crack the password successful. Store the password in a safe place in case changes need to be made to the router.

The inclusion of the software mentioned here is for the reader’s use. The authors have no interest in the software referenced in this chapter. Many software packages of a similar nature exist and new products are deployed regularly. Many of the vendors provide applications that provide blended protection, such as including a firewall, anti-malware, and data backup functions in one package. The reader should use the software mentioned as a starting point and research current versions and other software for potential use on the investigative computer system. Good research sites for reviews on protective tools are CNET (http://www.cnet.com), PC World (http://www.pcworld.com), and SC Magazine (http://www.scmagazine.com). These sites routinely evaluate, compare, and publish the results on protective software and hardware firewall device. Be careful with “free” versions of anything. Most of them come with some adware or tracking software which could expose an investigator.

China, Russia Posing Biggest Cyber Attack Threats to United States, Says Chief of US National Intelligence

China, Russia, Iran, and North Korea increasingly use cyber operations to steal information, influence people and to disrupt critical infrastructure, said Dan Coats, Director of National Intelligence.

Washington: Russia and China pose the biggest espionage and cyber attack threats to the United States and are more aligned than they have been in decades, the leader of the U.S. intelligence community told U.S. senators on Tuesday.

While the two countries seek to expand their global reach, Director of National Intelligence Dan Coats said, some American allies are pulling away from Washington in reaction to changing U.S. policies on security and trade.

“China, Russia, Iran, and North Korea increasingly use cyber operations to threaten both minds and machines in an expanding number of ways – to steal information, to influence our citizens, or to disrupt critical infrastructure,” Coats said.

“Moscow’s relationship with Beijing is closer than it’s been in many decades,” Coats told the Senate Intelligence Committee’s annual hearing on worldwide threats, where he testified with the director of the CIA, FBI and other top intelligence officials.

He also said some U.S. allies are seeking more independence, responding to their perceptions of changing policies on security and trade and “are becoming more open” to new partnerships.

“The post-World War Two international system is coming under increasing strain amid continuing cyber and WMD proliferation threats, competition in space and regional conflicts,” Coats said, using the acronym for weapons of mass destruction.

Election Security

Coats also said U.S. adversaries likely are already looking to interfere in the 2020 U.S. election, refining their capabilities and adding new tactics.

He said Russia’s social media efforts will continue to focus on aggravating social and racial tensions, undermining trust in authorities and criticizing politicians perceived to be anti-Russia.

Senator Mark Warner, the panel’s top Democrat, said in his opening statement that he was particularly concerned about Russia’s use of social media “to amplify divisions in our society and to influence our democratic processes” and the threat from China in the technology arena.

The United States on Monday announced criminal charges against China’s Huawei Technologies Co Ltd, escalating a fight with the world’s biggest telecommunications equipment maker and coming days before trade talks between Washington and Beijing.

“Especially concerning have been the efforts of big Chinese tech companies – which are beholden to the CCP (Chinese Communist Party) – to acquire sensitive technology, replicate it, and undermine the market share of U.S. firms with the help of the Chinese state,” Warner said.

The U.S. Justice Department on Monday charged Huawei and its chief financial officer, Meng Wanzhou, with conspiring to violate U.S. sanctions on Iran by doing business with Tehran through a subsidiary it tried to hide.

“China is going to be a major competitor of ours in every way that there is,” said Republican Senator Jim Risch, an intelligence

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
