25 Best Linux Security Tools You Should Try


 In recent times, the security aspect of information has become very important, and many organizations or companies are willing to create a special security team to monitor vulnerabilities or loopholes in their systems. Because in reality, any gap in security can have consequences for a business. When talking about security, many terms come to mind. Hacks, viruses, malware, data loss, etc. The following is a list of the 25 Best Linux Security Tools You Should Try.



1. MISP

MISP is the best Linux security tool widely known as a “Malware Information Sharing Platform” is a threat intelligence platform for sharing, storing, and linking threat intelligence signatures, economic racket information, vulnerability information, and anti-violence information. These Linux security tools are useful both for storing, sharing, collaborating cybersecurity alerts, malware exploration, and for using information and IoC to detect and prevent threats.


2. Wireshark

Wireshark (formerly known as Ethereal) is the next best Linux security tool which is a very powerful package analyzer tool for system administrators and is a popular open-source multi-platform utility for analyzing network protocols and packets. Features include real-time packet capture, browsing packet contents, and understanding the various protocols and their parts.


3. Privacy Badger

Privacy Badger is basically privacy protection for browsers giving them security against website visitor trackers. Trackers usually collect information about your browser. Collected information is often shared by third parties. Often used to create fake profiles of certain browsers. In such cases, these Linux security tools hinder data collection.


4. Firejails

Firejail is a community-driven SUID project that minimizes security breaches by managing the access that applications use using Linux namespaces and running seccomp-bpf. Firejail can easily sandbox servers, and GUI applications, and process login sessions and because it ships with multiple security profiles for various Linux programs including Mozilla Firefox, and VLC, transmission is easy to set up.


5. Aircrack-ng

Aircrack is an excellent network application package consisting of a packet sniffer, detector, WPA/WPA2-PSK and WEP cracker, and analysis utility for '802.11' wireless LANs. This software works flawlessly with any “wireless network interface controller” whose driver can manage both 802.11g and 802.11a, 802.11b traffic and also supports raw observing mode.


6. NMAP

NMAP is a flexible, portable, open-source tool for scanning networks and performing security audits. This tool analyzes the raw IP packets and then provides details about the live hosts on the network along with their banner information, port, services, and version running. Any accidentally opened port on the target system can be detected by the tool, and the necessary action can be taken. There are two versions of NMAP available, CLI and GUI known as Zenmap. Although both have basically identical functions, the GUI version has built-in scan profiles to scan targets easily. You can use this tool to manage service upgrade schedules, network inventory, monitor server uptime, etc.


7. Archery

Archery is an excellent Linux security tool that helps you gather information about the existing vulnerabilities in your operating system. The software not only concentrates on authentic scans but also allows the management of findings in an essentially web-based interface.


8. ClamAV

ClamAV is an excellent open-source antivirus at detecting viruses and trojans among other security and privacy threats. These tools are so powerful that they are considered the open-source standard for mail gateway scanning software tools. It also features a multi-threaded scanning daemon, support for multiple file formats, multiple signature languages, and command line utilities.


9. Anchor

Anchore is a Linux security program that can help you detect, assess and authenticate container images. You can save your images in the cloud and on-premises. This tool is mostly concentrated on developers so that they can achieve successful supervision of container images. Executing inquiries and generating reports is a signature activity of Anchore.


10. Snorts

Snort is a very powerful free open-source tool that helps in detecting intruders and also highlights malicious attacks on the system. In effect, Snort is just a packet filter. But the real value of this tool lies in detecting signature-based attacks by analyzing packets that Wireshark or tcpdump is not capable of analyzing.


11. Hashcat

Hashcat is a self-declared world's fastest password capture tool that has a copyright code base till 2015 and is now a completely free program. The hashes of Microsoft LM, Cisco PIX, MD4, MySQL, MD5, the Unix Crypt format, and the SHA family are basic examples of hashcat-supported hashing algorithms. This app comes in both GPU and CPU-based variants. The editions are compatible with Windows, Linux, and OS X.


12. John the Ripper

John the Ripper is one of the fastest password crackers and is available for multiple platforms including OpenVMS, Windows, DOS, and several versions of Unix. This tool is open-source but you can also get the Pro version for a fee. This tool can help you in detecting weak passwords.


13. Radare2

Radare2 is one of the popular Linux security tools for “reverse engineering” several different file types. You can use this tool to explore firmware, malware, or other 'binary files'. Apart from “reverse engineering”, you can even use it for forensics on file systems and data carving. With it, you can script tasks as well. This tool is also capable of using the software exploitation function in it.


14. Nessus

Nessus is proprietary software for scanning network vulnerabilities. This tool has two versions, free and paid. This tool features high-speed discovery, configuration audit, asset profiling, sensitive data discovery, and vulnerability analysis of your security posture. The free version lets you scan up to 16 IP addresses per scanner at high speed complete with in-depth ratings.


15. Bro

Bro can help you extensively perform security monitoring by looking at network activity. This Linux security utility can identify questionable data streams. Considers data, reacts to program alerts, and even integrates with other related tools. This excellent software has been developed by Vern Paxson who is now leading the project with a group of potential scientists and developers.


16.KeePass

KeePass is a cross-platform open-source password manager that frees you from the need to remember all your passwords. This tool stores all passwords in an encrypted database which can be unlocked with one master password or key file. It features a simple UI with a tree view, password groups, export/import, multi-language support, etc.


17. Faraday

Faraday is a real-time cooperative utility that increases speed, efficiency, and transparency for your and your team's assessments. These Linux security tools give you a superior perception and help make safer investments. This software serves many organizations around the world. It can even meet the requirements of various organizations offering the right solution for each case.


18. Nico

Nikto is an open-source web scanner to detect outdated server software, malicious files, and cookies, and performs generic and server-specific type checks. It features a template engine for reports, full HTTP proxy support, subdomain guessing, logging into Metasploit, LibWhisker IDS coding techniques, etc.


19. PTF

PTF stands for “PenTesters Framework” and is a Python script that aims to maintain your penetration analysis toolkit. This tool is an excellent Linux security program intended to run under Ubuntu, Arch Linux, Debian, or related clones. The tools basically work with modules where you get the definition of the method of fetching the tool and an overview of the things needed to build the tool.


20. OSQuery

OSQuery is an open-source and cross-platform tool for analyzing network and security leaks. This tool is the industry standard for performing continuous testing to check thread safety and detect memory leaks, and binary reproducibility. OSQuery also makes it possible to query your device like using a relational database using SQL commands for security, compliance, and developer operations.


21. Metasploit Framework

Widely used Metasploit tools are primarily for penetration testing but you can also use them to authenticate vulnerabilities, perform security assessments, and increase your security awareness to stay ahead of potential attackers.


22. Chkrootkit

Chkrootkit is an open-source utility for detecting local rootkits. Rootkits are a set of software tools used by 3rd parties to hide changes made to a computer system after a successful security bridge.
