A Clear Guide to Understanding Penetration Testing

Penetration Testing has become one of the most integral parts of a comprehensive security program. Pen Testers are responsible for mimicking the actual attackers. They use different tools and methods to exploit the organization’s systems, applications, and networks. Pen Testers think precisely like hackers, and they are responsible for finding the vulnerabilities in the system and they try to exploit them in different ways. At the end of this process, Pen Testers generate a complete report about the vulnerabilities and give it to the security professionals to fix the problems.

A Clear Guide to Understanding Penetration Testing

There are three types of Penetration Testing methods

WiteBox: In this type of testing, the Penetration Tester is provided with complete details like internal code, target network, and systems.
BlackBox: In this type of testing, the testers are not provided with any information at all. They are not aware of any internal code.
GrayBox: In this type of testing, the penetration tester will be aware of partial details of the system.

Before telling you why penetration testing is important, let me tell you the actual causes of vulnerabilities.

 

The causes of vulnerabilities:

  1. Human Errors: Oh yeah! Humans are built to make mistakes. Obviously, there would be code errors, unattended documents, insider threats, inappropriate administration of documents, sharing passwords, and many mistakes that could lead to security breaches.
  2. User Inputs: SQL injection, buffer overflows, and other security issues are probably familiar to you. This kind of data that is received electronically can be used to attack the receiving system.
  3. Development Errors: Errors while developing software and hardware can attract hackers. So try to avoid development errors.
  4. System Connections: It is very important to be conscious while connecting our systems to open connections. One unsecured connection can lead to big damage or data loss.
  5. Lack of Employee Training: As I said, people/humans often tend to make mistakes, and untrained employees can cause many vulnerabilities and errors.

Scenarios where we need Pen Testing the most:

  • We need pen testing when we are willing to find loopholes in our systems.
  • Pen testing is used when we want to secure user data.
  • When we want to implement new security strategies, pen testers are helpful.
  • Finding application security vulnerabilities is very easy with the help of pen testers.
  • Nowadays, clients are insisting on incorporating the pen-testing phase as a part of the release cycle.
  • Pen testing is used to meet the information security compliance requirements.
  • Pen testing is needed while assessing the business impact of successful cyber attacks.

  • Processes
  • Network
  • End-user behavior

Different Penetration Testing Tools:

Below are some of the great penetration testing tools.

Zmap: Zmap is a lightweight network scanner that can scan everything from your local network to the entire Internet. This free network scanner is ideal for gathering network baseline information.

SimplyEmail: SimplyEmail is an email reconnaissance application that helps you find related material on the Internet using someone’s email address. SimplyEmail is based on the harvester solution and searches the Internet for any data that can be used to provide intelligence about a given email address.

PowerShell-Suite: The PowerShell-Suite is a cluster of Powershell scripts that retrieve data about Windows DLLs, processors, handles, and many other things. We can easily check which particular system is vulnerable to exploitation by using this tool.

Wireshark: Wireshark is perhaps the most popular network protocol analyzer on the planet. Wireshark network traffic capture may reveal which protocols and systems are active and which accounts are the most active and allow attackers to collect sensitive data.

Hydra: Hydra is a tool for breaking passwords. Hydra is the only password pen testing programme that can simultaneously test various protocols and connections. If unlocked, this capability allows a penetration tester to break many passwords on multiple computers at the same time without losing connection.

Hashcat:

Hackers use Hashcat to crack passwords for licit and illicit purposes. By performing brute-force attacks with hashed passwords, the tool aides brute-force attacks in a swift, efficient, and versatile way, it utilizes hash values of passwords that it guesses and matches. As a means to reveal compromised or easy to guess credentials, it is usually used for benign purposes, such as penetration testing.
