In this post, I will explain top 10 Linux security tools package, and how they fit in the jigsaw that is called computer security for Linux.

top 10 linux security tool you cannot miss

1. Nmap 

Nmap (“Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available.

2. Nikto

nikto linux vulnerability scanner tool

Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3200 potentially dangerous files/CGIs, versions on over 625 servers, and version specific problems on over 230 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).

3. THC-Amap

A map is a next-generation tool for assisting network penetration testing. It performs fast and reliable application protocol detection, independent on the TCP/UDP port they are being bound to.

4. Ethereal

Ethereal Linux security tool

Ethereal is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education. It has all of the standard features you would expect in a protocol analyzer, and several features not seen in any other product.

5. THC-Hydra

Number one of the biggest security holes is passwords, as every password security study shows. Hydra is a paralyzed login cracker which supports numerous protocols to attack. New modules are easy to add, besides that, it is flexible and very fast.

6. Metasploit Framework

metasploit_Linux_security_tool

The Metasploit Framework is an advanced open-source platform for developing, testing, and using exploit code. This project initially started off as a portable network game and has evolved into a powerful tool for penetration testing, exploit development, and vulnerability research.

7. John the Ripper

John the Ripper is a fast password cracker, currently available for many flavours of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypts (3) password hash types most commonly found on various Unix flavours supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

8. Nessus

nessus linux security tools

Nessus is the world’s most popular vulnerability scanner used in over 75,000 organisations worldwide. Many of the world’s largest organisations are realising significant cost savings by using Nessus to audit business-critical enterprise devices and applications.

9. IRPAS

Internetwork Routing Protocol Attack Suite – Routing protocols are by definition protocols, which are used by routers to communicate with each other about ways to deliver routed protocols, such as IP. While many improvements have been done to the host security since the early days of the Internet, the core of this network still uses unauthenticated services for critical communication.

10. Rainbowcrack

rainbowcrack linux security tools

RainbowCrack is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. In short, the RainbowCrack tool is a hash cracker. A traditional brute force cracker tries all possible plaintexts one by one in cracking time. It is time-consuming to break complex password in this way. The idea of time-memory trade-off is to do all cracking time computation in advance and store the result in files so-called “rainbow table”.
