Network Security Tools

Scanning / Pentesting

• OpenVAS – OpenVAS is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution.
• Metasploit Framework – one fo the best Network Security Tools for developing and executing exploit code against a remote target machine. Other important sub-projects include the Opcode Database, shellcode archive and related research.
• Kali – Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. Kali Linux is preinstalled with numerous penetration-testing programs, including nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper (a password cracker), and Aircrack-ng (a software suite for penetration-testing wireless LANs).
• pig – A Linux packet crafting tool.
• scapy – Scapy: the python-based interactive packet manipulation program & library.
• Pompem – Pompem is an open-source Network Security Tools, which is designed to automate the search for exploits in major databases. Developed in Python, has a system of advanced search, thus facilitating the work of pentesters and ethical hackers. In its current version, performs searches in databases: Exploit-db, 1337day, Packetstorm Security…
• Nmap – Nmap is a free and open-source utility for network discovery and security auditing.

Monitoring / Logging

• justniffer – Justniffer is a network protocol analyzer that captures network traffic and produces logs in a customized way, can emulate Apache web server log files, track response times and extract all “intercepted” files from the HTTP traffic.
• httpry – httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the traffic as it is parsed, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications.
• ngrep – ngrep strives to provide most of GNU grep’s common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
• passivedns – one of the best Network Security Tools to collect DNS records passively to aid Incident handling, Network Security Monitoring (NSM) and general digital forensics. PassiveDNS sniffs traffic from an interface or reads a pcap-file and outputs the DNS-server answers to a log file. PassiveDNS can cache/aggregate duplicate DNS answers in-memory, limiting the amount of data in the logfile without loosing the essens in the DNS answer.
• sagan – Sagan uses a ‘Snort like’ engine and rules to analyze logs (syslog/event log/snmptrap/netflow/etc).
• Node Security Platform – Similar feature set to Snyk, but free in most cases, and very cheap for others.
• ntopng – Ntopng is a network traffic probe that shows the network usage, similar to what the popular top Unix command does.
• Fibratus – Fibratus is a tool for exploration and tracing of the Windows kernel. It is able to capture the most of the Windows kernel activity – process/thread creation and termination, file system I/O, registry, network activity, DLL loading/unloading and much more. Fibratus has a very simple CLI which encapsulates the machinery to start the kernel event stream collector, set kernel event filters or run the lightweight Python modules called filaments.

• sshwatch – IPS for SSH similar to DenyHosts written in Python. It also can gather information about the attacker during the attack in a log.
• Stealth – File integrity checker that leaves virtually no sediment. Controller runs from another machine, which makes it hard for an attacker to know that the file system is being checked at defined pseudo random intervals over SSH. Highly recommended for small to medium deployments.

• Xplico – The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico isn’t a network protocol analyzer. Xplico is an open source Network Forensic Analysis Tool (NFAT).
• Moloch – Moloch is an open source, large scale IPv4 packet capturing (PCAP), indexing and database system. A simple web interface is provided for PCAP browsing, searching, and exporting. APIs are exposed that allow PCAP data and JSON-formatted session data to be downloaded directly. Simple security is implemented by using HTTPS and HTTP digest password support or by using apache in front. Moloch is not meant to replace IDS engines but instead work along side them to store and index all the network traffic in standard PCAP format, providing fast access. Moloch is built to be deployed across many systems and can scale to handle multiple gigabits/sec of traffic.
• OpenFPC – OpenFPC is a set of tools that combine to provide a lightweight full-packet network traffic recorder & buffering system. It’s design goal is to allow non-expert users to deploy a distributed network traffic recorder on COTS hardware while integrating into existing alert and log management tools.

Wireshark is very similar to tcpdump, but has a graphical front-end, plus some integrated sorting and filtering options.
• netsniff-ng – netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa.
