Everything You Need to Know About Firewall Penetration Testing

Firewall penetration testing can be used to assess the strength of a firewall and identify potential weaknesses that could be exploited by hackers. But what is Firewall penetration testing? We’ll see what it is and why It is important to conduct regular firewall penetration tests to ensure the security of your network and protect your data from unauthorized access. In this article, we will also discuss different types, different techniques for performing firewall penetration testing, and some of the best firewall penetration testing solutions available on the market.

What is Firewall Penetration Testing?

A firewall penetration test determines how effectively a company’s network is protected against unlawful access. It’s a type of security testing designed to assess whether a firewall is capable of stopping illicit traffic.

In order to test the firewall, various methods are used to try and access the network from an external location. Port scanning and packet sniffing are two methods that attackers use to break into networks. If the firewall is working correctly, we should not be able to access the network in the first place.

A firewall penetration test can be done manually or through the use of automated tools, whichever you prefer. Manual testing takes more time and expertise, but it can cover more ground.

Why do You Need to Conduct Regular Firewall Penetration Testing?

A firewall penetration test is an essential security measure to help you identify weaknesses and the likelihood of a future attack. By mapping out your network externally, you can get an idea of where there might be gaps in your defences.

The first step in defending against a cyber attack is to understand where traffic enters and exits your network. By performing this test, you can find any openings in your network an intruder could use to get inside. For example, you need to know the location of your wireless Access Point (AP) if it is accessible through the Internet.

3 Distinct Kinds of Firewall Penetration Testing

  1. Man in the Middle (MiTM): A MiTM test, used by security researchers to find vulnerabilities, involves intercepting and changing traffic between a firewall and the clients attempting to connect to the network. This type of testing is often done against remote users because it allows an attacker easy access to hijacking their traffic and thus getting onto the network without detection. Once in, the attacker would then have complete control over all remote user data.
  2. Direct Traffic: A direct traffic test is where a security researcher essentially “hacks” into web and application servers to explore the internal network for any vulnerabilities that could be exploited to gain access to sensitive information. An attacker uses this method to test an organization’s security when it comes to employees who work there. It’s a form of “internal reconnaissance” testing.
  3. Spoofed Traffic: A traffic spoofing test is where an attacker employs a tool to send out fraudulent network traffic that closely resembles a remote user attempting to access the internal network. The attacker can access the entire internal network if the connection is successful, similar to an “internal reconnaissance” test.

Firewall Penetration Testing 3 Different Techniques

  1. Black Box Testing: In black box testing, the tester runs tests from the outside of the system and has no understanding of how it works.
  2. White Box Testing: With white box testing, the firewall tester has complete knowledge of how the system works and tests it internally.
  3. Gray Box Testing: Gray box testing is done by pentesters who know a little about the firewall system being tested, and this person tests it from an external perspective.

To ensure the efficiency of your firewall, it is essential to conduct penetration testing. This will give you a complete overview of any potential weaknesses in your system so that you can address them accordingly.
