Network Security Toolkit (NST) is a bootable ISO image (Live USB Flash Drive) based on Fedora 42 providing easy access to best-of-breed Open Source Network Security Applications and should run on most x86_64 systems. The main intent of developing this toolkit was to provide the security professional and network administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 125 Security Tools by INSECURE.ORG are available in the toolkit. An advanced Web User Interface (WUI) is provided for system/network administration, navigation, automation, network monitoring, host geolocation, network analysis and configuration of many network and security applications found within the NST distribution. In the virtual world, NST can be used as a network security analysis, validation and monitoring tool on enterprise virtual servers hosting virtual machines.

Buck-Security is a security scanner for Debian and Ubuntu Linux. It runs a couple of important checks and helps you to harden your Linux system. This enables you to quickly overview the security status of your Linux system. As a system administrator you often get into situations where you have to take care of a server, that has been maintained by other people before. In this situation it is useful to get an idea of the security status of the system immediately. Buck Security was designed exactly for this. It runs a few important checks and returns the results.

EQGRP is a public release of the so-called Equation Group hacking tools, originally leaked online in 2017. The repository serves as an archive and reference for security researchers, documenting the exploit frameworks, implants, and utilities that were allegedly used by a highly sophisticated threat actor. The tools include network exploitation scripts, backdoors, and frameworks targeting a range of platforms and services, many of which highlight previously unknown vulnerabilities. While the repository itself is provided for educational and research purposes, it also reflects a significant historical moment in cybersecurity, influencing both defensive strategies and awareness of advanced persistent threats. The release offers researchers insight into real-world offensive techniques, though many of the specific exploits are now outdated or patched. EQGRP remains a controversial but important resource for studying the evolution of nation-state-level cyber operations.

Bypass is an IP forwarding/tunneling tool which can be used where limited bypassing of a firewall is necessary, but relaxing the restrictions in the actual firewall is not an option. The aim is for bypass to be automatic and transparent.

Operative Systems Suported are: Linux-ubuntu, kali-linux, backtack-linux (un-continued), freeBSD, Mac osx (un-continued) Netool its a toolkit written using 'bash, python, ruby' that allows you to automate frameworks like Nmap, Driftnet, Sslstrip, Metasploit and Ettercap MitM attacks. this toolkit makes it easy tasks such as SNIFFING tcp/udp traffic, Man-In-The-Middle attacks, SSL-sniff, DNS-spoofing, D0S attacks in wan/lan networks, TCP/UDP packet manipulation using etter-filters, and gives you the ability to capture pictures of target webbrowser surfing (driftnet), also uses macchanger to decoy scans changing the mac address. Rootsector module allows you to automate some attacks over DNS_SPOOF + MitM (phishing - social engineering) using metasploit, apache2 and ettercap frameworks. Like the generation of payloads, shellcode, backdoors delivered using dns_spoof and MitM method to redirect a target to your phishing webpage. recent as introducted the scanner inurlbr (by cleiton)

New improved iptables tool, based on my earlier project Easy Linux Firewall, but rewritten from scratch using Perl. It's a simple rewrite for now, but i am working on adding some new features like. Some of the improvements will be web administration panel, automatic filtering daemon, TCP listener providing easy to use API so you can integrate it on many servers and centralize them in to one Web interface to control all of them. I am open to new ideas and also any kind of contributors, because I'm working on this alone and it isn't easy, so you are welcome to help.
