A penetration test, or pen test, is the simulation of a cyber attack. The goal is to assess a network’s security to improve it and thus prevent exploits by real threat actors by fixing vulnerabilities. Show This critical IT security practice isn’t the same as a vulnerability assessment or vulnerability scanning, though, as pen testing involves an actual attack similar to what hackers would do in real-world conditions. Pen tests are often performed by third parties, but as these outside tests can be expensive and become dated quickly, many organizations perform their own tests with pen testing tools, using their own IT personnel for their red teams (attackers). When shopping for a penetration testing tool, be aware that you will likely need several components to perform a complete penetration test. Some software solutions let users define custom rules according to a specific use case. There are a number of complementary technologies often used by organizations to address security holes. Breach and attack simulation, for example, can be something of an automated, continuous pen testing tool. Others include vulnerability scanning tools and vulnerability management solutions. And IT asset management and patch management are important tools for staying on top of known vulnerabilities. A significant number of the tools below are included in Kali Linux, a dedicated operating system for pen testing and ethical hacking. Installing Kali can remove the hassle of downloading and installing these tools separately.

It’s a big market, though, so we also have a second article on the Top Open Source Penetration Testing Tools. Best Network Scanning and Enumeration ToolsNmap Free Security Scanner
Nmap, included in Kali Linux, is a free package of command lines you can run in a terminal to achieve various tasks, such as discovering open ports, which ultimately allows you to detect vulnerabilities. This tool is pretty helpful for scanning large networks fast. Behind the scenes, it uses raw IP packets to identify available hosts and services on the network. Pros
Cons
Useful linksWireshark
Wireshark is probably the most popular network protocol analyzer. It’s a packer scanner (or sniffer) you can find in Kali Linux, but you can also install it as a standalone software or package in most operating systems. Pros
Cons

Gobuster Directory ScannerGobuster can be used with Kali Linux, but you can also install it as a package using the command sudo apt install gobuster. It’s an efficient software that can be used to enumerate hidden directories and files quickly. Many web apps use default directories and filenames that are relatively easy to spot. As a result, the tool can use brute force techniques to discover them. Pros
Cons
Useful linksAmassAmass is an open-source network mapper that is particularly efficient for DNS (Domain Name System) and subdomain enumeration. Pros

Best Password CrackersPassword cracking consists of retrieving passwords stored in computer systems. System administrators and security teams (and hackers) can use them to spot weak passwords. John the RipperJohn the Ripper is probably one of the most popular free password crackers included in Kali Linux, but it also has a premium version. The software combines various techniques to crack passwords. Pros
Cons

MedusaMedusa is a powerful brute-force tool with pretty interesting features included in Kali Linux. This command-line tool can also be installed as a Linux package using the command sudo apt install medusa. Pros

NcrackThis software, included in Kali Linux, can test all hosts and devices in a network for weak passwords. It’s a set of command lines that can scan large networks, allowing sophisticated brute-force attacks. Pros
Cons
Useful linksBest Pen Testing FrameworksThere are tools that are, in fact, collections of security tools you can use to run penetration tests. It can cover both the scanning part and the exploit. The Burp suite
Burp is a top-rated software suite for attacking. You can find it in the Kali Linux community edition. It’s a tremendous tool in the arsenal that can do advanced scans, but one of the most classic uses is traffic interception (e.g., HTTP requests). Pros
Cons

Metasploit
Metasploit, developed by Rapid7, is a well-known exploitation framework that’s also included in Kali Linux. It provides useful modules and scanners to exploit vulnerabilities. Pros

Other Pen Test and Scanning ToolsWe’ve given you our picks for the top pen test tools, but there are a number of others out there you may want to consider. Nessus is a widely used paid vulnerability assessment tool that’s probably best for experienced security teams. Fiddler is a useful collection of manual tools for dealing with web debugging, web session manipulation, and security/performance testing. However, it is probably most useful for those deploying the paid version on the .NET framework, as that comes with many automation features. Aircrack-ng is the go-to tool for analysis and cracking of wireless networks. All the various tools within it use a command line interface and are set up for scripting. wp-scan is a great tool for anyone using WordPress. It scans for known vulnerabilities, enumerating users and brute forcing logins. wifite is a wireless network auditor that deals with current or legacy attacks against WEP and WPA2. hashcat is used to crack hashes discovered during pen tests, including GPU and CPU cracking. trufflehog searches through Git repositories for secrets (API tokens, hard-coded credentials, etc.). SQLmap automates the detection and exploitation of SQL injection flaws and database server takeovers. OWASP ZAP is a web application security scanner that is good for beginners. Social Engineer Toolkit (SET) defends against human error in social engineering threats. THC-Hydra is a network login cracker that supports Cisco auth, Cisco enable, IMAP, IRC, LDAP, MS-SQL, MYSQL, Rlogin, Rsh, RTSP, SSH and more Drew Robb also contributed to this guide |
