Network pen testing, in simple terms, means trying to break into a computer system or network to find out if there are security problems. Testers try different ways to get into systems, like using weak spots, tricks, and forceful methods.

What Are The Key Steps Involved in Network Penetration Testing?

According to reports, the number of cybersecurity threats is increasing constantly. These threats include things like ransomware attacks, crypto jacking, cyber-physical attacks, and other types of online attacks. Any kind of cyberattack leads to losing money and causing permanent harm to a company's reputation. 

Since there's a lot to lose, businesses spend a lot of money to create products that are more secure, can handle growth, and can be trusted. Making sure computer networks and systems are safe is really necessary. Network penetration testing techniques help with that. 

 

It's like acting like a hacker to find weak spots that bad people could use. Here are the main steps that usually happen during the network penetration testing process:

1. Planning and Preparation

This is where the experts decide what they're going to do during the test. They work with the organization to figure out the goals, scope, and limitations of the test. This step is like planning a mission.

2. Discovery and Reconnaissance

In this step, the testers gather information about the network they're going to test. They find out things like what devices are on the network and how they're connected. It's like gathering clues before solving a mystery.

3. Scanning and Enumeration

Testers use tools to scan the network for weaknesses and perform different vulnerabilities analysis. They look for open doors that hackers could use to get in. This is like checking all the locks in a house to make sure they're strong.

4. Exploitation and Testing

Here, the testers act like hackers and try to use the weaknesses they found to get into the network. It's like trying to open those doors they found in the previous step.

5. Reporting and Recommendations

After the testing is done, the experts write a report. They explain what they found, how they got in, and what needs to be fixed. 

This helps the organization know what they can do to make their network safer and stronger. It's like giving advice on how to make a castle more secure after finding hidden passages.

Different Types of Network Penetration Testing

There are various types of network penetration testing, each designed to target specific security weaknesses. These variations enable organizations to thoroughly evaluate their networks and systems.

 

When organizations choose the right type, they can find and fix weak points before any issues arise. This helps keep their networks strong and safe. 

Here are the top 8 examples of these network testing types that you can consider:

1. Black Box Penetration Testing

In this way of testing, the experts don't know much about the network they're checking. It's like trying to solve a puzzle with only a few hints. Testers simulate real-world hacking attempts to gauge how well the network can defend itself against unexpected attacks.

2. White Box Penetration Testing

Contrasting with black box testing, white box testing gives testers full access to the network's internal structure, like having a map of a building. This allows for a deeper assessment of vulnerabilities within the system's architecture, code, and configurations.

3. Grey Box Penetration Testing

As the name suggests, grey box testing is a blend of black and white box testing. Testers have partial knowledge about the network, somewhat like knowing some parts of a map. This approach offers a balance between realistic attack scenarios and a deeper understanding of the network's inner workings.

4. External Network Penetration Testing

Let read here, what is external penetration testing. In this testing, testers focus on vulnerabilities that are accessible from the outside, much like checking the exterior of a house for weak points. They evaluate how an attacker might exploit exposed entry points, such as web applications, email servers, or public-facing services.

5. Internal Network Penetration Testing

Internal testing dives into vulnerabilities that an attacker with insider access could exploit. This is akin to checking the security inside a building. Testers assess the risks posed by employees or contractors who might have unauthorized access to sensitive systems.

6. Blind Penetration Testing

In blind testing, testers have little to no information about the network, like entering a maze without a map. This helps mimic the conditions of a real attack, where the tester must start from scratch, giving organizations insights into how they might react to an unexpected threat.

7. Targeted Penetration Testing

This type focuses on specific areas of a network or particular vulnerabilities. It's like looking closely at specific parts of a painting. Organizations choose this when they want a concentrated examination of potential weak points.

8. Social Engineering Penetration Testing

In this unconventional approach, testers attempt to exploit human behavior to gain unauthorized access, simulating real-world scenarios where employees might unknowingly provide access to attackers. It's like testing people's reactions to unexpected visitors at their doorstep.
