In today’s interconnected world, ensuring your digital assets’ security is paramount. As cyber threats continue to evolve, it’s crucial to have effective security testing tools at your disposal. Fortunately, the open-source community offers a wealth of powerful security testing tools to help identify vulnerabilities and strengthen defenses. In this blog post, we’ll explore some of the top open-source security testing tools you can use today.

OWASP ZAP (Zed Attack Proxy): OWASP ZAP is a popular open-source web application security scanner. It provides a comprehensive set of features for finding vulnerabilities in web applications, including automated scanning, manual testing, and security analysis. ZAP is highly extensible, allowing you to customize and enhance its capabilities according to your specific requirements. It’s an invaluable tool for identifying common web application vulnerabilities like cross-site scripting (XSS), SQL injection, etc.
Nmap (Network Mapper): Nmap is a versatile and powerful open-source network scanning tool for security auditing and network exploration. With its extensive scanning techniques, Nmap can map out hosts, identify open ports, and detect potential vulnerabilities. It supports a scripting engine that enables you to automate tasks and create custom scripts for targeted scanning. Nmap is an essential tool for assessing network security and identifying potential entry points for attackers.
Wireshark: Wireshark is a widely used open-source packet analyzer for network troubleshooting and security analysis. It allows you to capture and examine network traffic at a granular level. Wireshark provides detailed insights into network protocols, allowing you to detect anomalies, analyze network behavior, and identify security threats. Its robust filtering capabilities and extensive protocol support make it an indispensable tool for network security professionals.
Metasploit Framework: The Metasploit Framework is a powerful open-source penetration testing platform that enables you to assess and exploit vulnerabilities in systems and applications. With a vast collection of exploits, payloads, and auxiliary modules, Metasploit simplifies the process of penetration testing and helps security professionals validate the effectiveness of their defenses. It also offers a collaborative community and a wide range of resources for sharing knowledge and expertise.
Nikto is an open-source vulnerability scanner to identify security flaws in web servers and applications. It performs comprehensive tests, including server misconfigurations, outdated software versions, and potentially dangerous files or scripts. Nikto provides detailed scan reports, making prioritizing and remediating identified vulnerabilities easier. Its simple command-line interface and extensive plugin support make it a valuable tool for security testing.

Securing your digital assets requires a proactive and comprehensive approach. By leveraging open-source security testing tools, you can enhance your security posture and protect against potential threats. The tools mentioned in this blog post, including OWASP ZAP, Nmap, Wireshark, Metasploit Framework, and Nikto, offer powerful capabilities to identify vulnerabilities, assess network security, and perform penetration testing. Start exploring these open-source tools today and take a proactive stance in securing your systems and applications. Remember to stay updated with the latest releases and actively participate in the open-source community to maximize the benefits of these valuable resources.

Metasploit Framework Metasploit Framework – an open-source tool for exploit development and penetration testing. Metasploit is well known in the security community. Metasploit has exploited for both server and client-based attacks; with feature-packed communication modules (meterpreter) that make pwning systems fun! The framework now includes Armitage for point and click network exploitation. This is the go-to tool if you want to break into a network or computer system.

Defending against Metasploit :

Keep all software updated with the latest security patches.
Use strong passwords on all systems.
Deploy network services with secure configurations.

Ettercap Ettercap – a suite of tools for man in the middle attacks (MITM). Once you have initiated a man in the middle attack with Ettercap, use the modules and scripting capabilities to manipulate or inject traffic on the fly. Sniffing data and passwords are just the beginning; inject to exploit FTW!

Defending against Ettercap :

Understand that ARP poisoning is not difficult in a typical switched network.
Lockdown network ports.
Use secure switch configurations and NAC if the risk is sufficient.

SSLStrip sslstrip – using HTTPS makes people feel warm, fuzzy, and secure. With sslstrip, this security can be attacked, reducing the connection to an unencrypted HTTP session, whereby all the traffic is readable. Banking details, passwords, and emails from your boss, all in the clear. Even includes a nifty feature where the favicon on the unencrypted connection is replaced with a padlock just to make the user keep that that warm fuzzy feeling.

Defending against sslstrip :

Be aware of the possibility of MITM attacks (arp, proxies/gateway, wireless).
Look for sudden protocol changes in the browser bar. Not really technical mitigation!

Evilgrade evilgrade – another man in the middle attack. Everyone knows that keeping software updated is the way to stay secure. This little utility fakes the upgrade and provides the user with a not so good update. Can exploit the upgrade functionality on around 63 pieces of software including Opera, Notepad++, VMware, Virtualbox, iTunes, QuickTime and Winamp! It really whips the llama’s ass!

Defending against evilgrade :

Be aware of the possibility of MITM attacks (arp attacks, proxy/gateway, wireless).
Only perform updates to your system or applications on a trusted network.

Social Engineer Toolkit Social-Engineer Toolkit – makes creating a social engineered client-side attack way too easy. Creates the spear phish, sends the email and serves the malicious exploit. SET is the open-source client-side attack weapon of choice.

Defending against SET:

User awareness training around spear phishing attacks.
Strong Email and Web filtering controls.

SQLmap sqlmap – SQL Injection is an attack vector that has been around for over 10 years. Yet it is still the easiest way to get dumps of entire databases of information. Sqlmap is not only a highly accurate tool for detecting SQL injection, but also has the capability to dump information from the database and to even launch attacks that can result in operating system shell access on the vulnerable system.

Defending against sqlmap :

Filter all input on dynamic websites (secure the web applications).
Use mod_proxy or other web-based filtering controls to help block malicious injection attacks (not ideal as often able to bypass these web application firewalls (WAF).

Aircrack-NG aircrack-ng – breaking holes in wireless networks for fun and profit. A suite of tools that enables all manner of wireless network attacks.

Defending against aircrack-ng:

Never use WEP
When using WPA2 with pre-shared keys, ensure passwords are strong (10+ characters non-dictionary based passwords).

oclHashcat oclHashcat – Need to get some passwords from the hashes you grabbed with sqlmap? Use this tool to bust them open. Over 48 different hashing algorithms supported. Will use the GPU (if supported) on your graphics card to find those hashes many times faster than your clunky old CPU.

Defending against oclHashcat:

Passwords are the weakest link. Enforce password complexity.
Protect the hashed passwords.
Salt the hashes.
