Penetration testing: what it is, importance, types and best tools

Penetration testing, often referred to as “pentesting”, is a process of identifying and exploiting vulnerabilities in a computer system or network. Slope tests can be performed on individual systems, networks or applications. There are several types of penetration testing, each with its own set of objectives and methods. In this blog post, we will discuss the different types of penetration testing, tools used for penetration testing, and how you can get started with penetration testing.

Importance of Penetration Testing Software

Penetration testing software is essential because it allows companies and organizations to discover and repair flaws in their computer systems and networks before they are attacked. By identifying these vulnerabilities, penetration testing can help prevent data breachfinancial loss and damage to reputation.

What is a Penetration Test Device?

A penetration test device is a piece of hardware or Software used to test the security of a computer system or network. Scanners, firewalls, and honeypots are just a few of the many types of penetration testing devices.

Software (operating systems, services, applications), hardware, networks, processes and end-user behavior are also part of a penetration testing device.

Types of Penetration Tests

  • External testing: This type of penetration test is performed from outside a network and is designed to simulate an attack by a real-world attacker.
  • Internal testing: This type of penetration test is performed from inside a network and is designed to identify vulnerabilities that could be exploited by someone with access to the internal network.
  • Blind tests: It is a blind test of a system or network that has never been tested before. The goal of blind testing is to uncover as many vulnerabilities as possible.
  • Double-blind test: This type of penetration test is performed without the tester and the target knowing each other. Double-blind testing is used to simulate a real-world attack and to find vulnerabilities that could be exploited by someone with knowledge of the system or network.
  • Targeted test: This type of penetration test is conducted against a specific target, such as a server or application. Targeted testing is used to find vulnerabilities in a specific system or component.

How Penetration Testing Works

Penetration testing is typically conducted in four stages: reconnaissance, scanning, exploitation, and post-exploitation.

  • During the first stage of a penetration test, reconnaissance, you gather information about the target system or network. This data can be obtained manually or using automated tools.
  • Scanning is the second step in a penetration test and involves using automated tools to scan the target system or network for vulnerabilities.
  • The third stage of a penetration test is exploitation, which consists of exploiting flaws in the target system or network. This can be done manually or using an automated system. presentation software.
  • Post-exploitation is the fourth stage of a penetration test and involves conducting activities after successfully exploiting a vulnerability. This may include collecting sensitive information, installing malware, or creating backdoors.

Main Penetration Testing Tools

The “Astra Security” product, the Astra Pentest, is based on one fundamental idea: to make the pentest process as easy as possible for customers. It’s rather unusual to see Astra go to great lengths to create self-contained solutions while still remaining accessible and on-time with support. Making fault detection, exploration and resolution as easy as performing a Google search is something Astra has done.

The user has a dedicated dashboard to view vulnerabilities, read CVSS scores, contact security personnel, and get remediation assistance.

Astra has added a number of new customers over the past year, including ICICI, UN and Dream 11 to an already impressive list that includes Ford, Gillette and GoDaddy.

The term “Nmap” refers to a popular network scanning and scanning program. It uses port scanning and other techniques to scan ports, detect operating systems, and produce a list of devices with running services as part of its mapping process.

NMAP generates packets of different shapes for various transport layer protocols, which include IP addresses and other data. You can use this data to discover hosts, develop an operating system fingerprint, discover services, and perform security monitoring.

Nmap is a versatile tool that can map large networks with hundreds of ports.

Metasploitable is a prime example of a vulnerable website application which has been exploited in the wild. Metasploit is used by both hackers and security professionals to identify widespread vulnerabilities. It is a powerful platform with elements of fuzzing, anti-forensic and evasion tools included.

Installations are straightforward and can be performed on a variety of operating systems. His popularity among pirates partly depends on this fact. This is one of the reasons why Metasploit is considered such a valuable hacking tool.

Metasploit now includes nearly 1677 exploits in addition to about 500 payloads, which include command shell payloads, dynamic payloads, meterpreter payloads, and static payloads.

A popular open source tool for protocol analysis, WireShark is a well-known brand. You can observe network activity at a subcellular level using this software. Its flexibility, ease of use, and features make it one of the best pentest tools available. Hundreds of security experts from around the world contribute to its development, making it one of the most advanced pentesting tools available.

It is essential to remember that WireShark is not an intrusion detection system or an IDS. It can show you where the problems are, but it can’t raise the alarm on malicious behavior on the network because a protocol analyzer might not disclose that information.

Intruder is a powerful vulnerability scanner that identifies cybersecurity flaws in your digital assets, assesses risk, and guides you through the remediation process before a breach occurs. It is a great tool to automate your penetration testing activities.


Penetration testing is the process of detecting and exploiting security flaws in a system in order to gain access to sensitive information or systems. It is important because it helps organizations find and fix security vulnerabilities before they can be exploited by attackers.

Tools like Astra’s Pentest, NMAP, Metasploit, WireShark, and Intruder can help you perform penetration testing more efficiently.
