What You Need to Know About Network Penetration Testing: Best Tools, Processes, and More

Do you know how to secure your networks from potential cyberattacks? If not, you’re not alone. A recent study showed that nearly 60% of businesses don’t have a formal security policy in place. And even if you do have a policy, it’s likely that it doesn’t include network penetration testing. This is a huge and pricey mistake, as network penetration testing is one of the best ways to secure your networks from attacks.

The term “penetration testing” refers to an effort to expose security flaws within a computer system or network. By identifying and addressing these vulnerabilities, you can improve the security of your systems and protect your data from unauthorized access.

In this blog post, we will discuss what you need to know about network penetration testing, including the best tools, steps, checklist, and tips. Other mentions within this article include merits and demerits and even resources for network pentesting with any further ado!



The practice of attempting to breach a computer system or network in order to discover security flaws is known as penetration testing. Pentesters use a variety of methods to attempt to gain access to systems, including exploiting vulnerabilities, using social engineering techniques, and brute force attacks.



There are many reasons why you might want to perform penetration testing on your company’s network. Perhaps you’re required to do so by law or by your industry regulator. Maybe you’ve experienced a data breach and need to shore up your defenses. Maybe you want to be confident in the security of your systems.

Whatever the reason, performing regular penetration tests can help improve the security of your network and protect your data from unauthorized access.



There are many different tools that pentesters can use to test the security of a network. Some of the most popular ones include:

  • Astra’s Pentest: One of the best tools out there for network penetration testing, Astra’s Pentest provides a wide range of services. It is provided by Astra Security.
  • Nmap: A free and open-source tool used for port scanning, OS identification, and vulnerability mapping.
  • Wireshark: A network traffic analyzer that allows you to log and analyze activity on a network.
  • Metasploit: A platform for developing and executing exploit code against a target system.
  • Burp Suite: A suite of tools designed to help testers perform web application pentest.
  • Kali Linux: An operating system specifically designed for penetration testing.



So, you’ve decided to start using network penetration testing tools. But how do you actually go about performing a penetration test? The process of conducting a network penetration test usually involves the following steps:

  • Gathering information about the target network and systems.
  • Scanning the target network for vulnerabilities.
  • Exploiting any vulnerabilities that are found.
  • Reporting on the findings of the test.

Figuring out which machine or machines you want to attack and test is the first step. You can do this by running a port scan or vulnerability assessment on the target system. After you’ve discovered the system you want to attack, you may then start enumerating its vulnerabilities.

Next, you’ll want to exploit any identified vulnerabilities on the target system. You may also use a variety of tools, such as Nmap, Metasploit, and Wireshark, to accomplish this.

Once you have successfully exploited one or more vulnerabilities on the target system, it’s time to start gathering information about the system. This can include information such as usernames, passwords, and sensitive data.

Once a penetration test is completed, a report detailing their findings will be generated. This report can be used to help improve the security of the target network and protect it from future attacks.

Finally, you’ll want to document your findings and present them to the target system’s owner or an administrator. By doing so, you can help them secure their systems from potential attacks.

these are the basic steps for performing a network penetration test. Follow these procedures to effectively defend against possible assaults on your networks. The specific steps will vary depending on your particular needs and environment, but these are typically the stages that pentesters go through when carrying out a penetration test.



If you’re looking to get started with network penetration testing, here is a checklist of things you’ll need:

  • A computer running a Linux or Windows operating system.
  • A network adapter.
  • Gather information about the target system
  • Enumerate vulnerabilities on the target machine
  • Exploit identified vulnerabilities on the target machine
  • Network scanning and exploitation tools such as Nmap, Wireshark, Metasploit, and Burp Suite.
  • Ability to use these tools effectively.
  • The willingness to experiment and take risks!



If you want to learn more about network penetration testing, then there are a few resources that you should check out.

  • The first resource is Astra’s Pentest Suite’s website. They have a comprehensive list of the best network penetration testing tools available, as well as tutorials and articles on how to use them.

  • Finally, another great resource is the Nmap website. Nmap is a helpful open-source software for network exploration. The Nmap website has a wealth of information on how to use the tool, as well as tutorials and articles on various aspects of network security.

These are just a few of the many resources available on network penetration testing. By taking the time to learn about this important topic, you can make your networks much more secure from potential attacks. So don’t wait – start learning today!



Like all security testing techniques, network penetration testing has its advantages and disadvantages. Some of the benefits include:

  • Discover security flaws in the network that might be attacked by attackers.
  • Helps to improve the security of the network.
  • Gives you a chance to test your incident response procedures.

Some of the drawbacks include:

  • Requires specialized knowledge and skills.
  • Can be difficult and costly to switch web hosting providers.
  • The danger of causing harm to systems if the procedure isn’t followed correctly.

Network penetration testing can be a useful tool for improving the security of your network, but it’s important to weigh the pros and cons before deciding if it’s right for you.



Here are some tips to help you get the most out of your network penetration testing:

  • First, always test in a controlled and safe environment. When you get your business up and running, the first thing to do is consider all of the ideas that have been proposed by people who understand what they’re doing. This will help you avoid unintentionally damaging production processes.
  • Second, make sure to document everything that you do. This documentation can be used to help the target system’s owner or administrator secure their systems from potential attacks.
  • Third, use a variety of different tools and techniques when performing a penetration test. This will help you identify as many vulnerabilities as possible.
  • Finally, be patient and take your time. Penetration testing can be a complex process, so don’t try to do it all in one sitting. Take your time and study the target system thoroughly.
  • Be methodical. Follow a systematic approach and document everything you do.
  • Keep an open mind. Prepare to experiment and break the mold.
  • Practice, practice, and practice some more! The more you practice, the better you’ll get at pentesting.

Network penetration testing can be a complex and technical process, but it is an essential part of keeping your network secure. You can ensure that your tests are effective and informative by following these guidelines.



Penetration testing is a method of finding and exploiting security flaws in a network. It can be used to improve the security of the network, identify attack vectors, and test incident response procedures. Network pen testing requires specialized knowledge and skills, so it’s important to weigh the pros and cons, your requirements, and the tools available before deciding if it’s right for you.
