Network Time Tools (NTT) is a set of network tools designed to provide monitoring of a network and the services on that network, and provide various reports on the hosts/services and optional alerts via email, pager, and cellphones. It comes with a protocol scanner, a bandwidth measurement tool, and a CGI front end that can handle a regular browser or WAP-enabled cellphones via WML.
NTMF is a C++ framework for developing software that requires the manipulation of packets traversing a system. The main application areas are protocol testing, protocol implementation testing, network emulation, and network monitoring. It has support for link level packet capturing (using libpcap), link level packet injection, and network level packet injection for IPv4 packets (using lipnet). It supports multi-threaded execution, provides thread-safe packet queues, and provides a dynamic Finite State Machine representation.
Netzob supports the expert in reverse engineering, evaluation, and simulation of communication protocols. Its main goals are to help security evaluators to assess the robustness of proprietary or unknown protocol implementations, simulate realistic communications to test third-party products (IDS, firewalls, etc.), and create an Open Source implementation of a proprietary or unknown protocol. Netzob provides a semi-automatic inferring process, and includes everything necessary to passively learn the vocabulary of a protocol and actively infer its grammar. The learnt protocol can afterward be simulated. Netzob handles text protocols (like HTTP and IRC), fixed field protocols (like IP and TCP), and variable field protocols (like ASN.1-based formats).
Nexus is a new operating system for trustworthy computing. It can take advantage of Trusted Platform Modules (TPMs) to issue trustworthy certificates of program properties. It provides user-level device drivers, isolated protection domains, interprocess communication, and partial POSIX support. It runs on x86 hardware.
NiX Brute Forcer is a tool that uses brute force in parallel to log into a system without having authentication credentials beforehand. This tool is intended to demonstrate the importance of choosing strong passwords. NiX supports a variety of services that allow remote authentication, such as HTTP(S) BASIC/FORM, MySQL, SSH, and FTP. It is based on NiX Proxy Checker.
Nift (Network Intrusion Footprinting Tool) is graphical frontend (written in GTK+) for footprinting tools and methods already freely avaliable. Its purpose is to aid sysadmins in securing their site by allowing them to quickly check their network to see how much data can be gained by an attacker and used towards cracking their systems.
Nightwing allows the creation of quickly deployed wireless networks without the need to make complicated configurations. With the implementation of a Mesh technology called B.A.T.M.A.N, Nightwing allows the extension of wireless networks with a simple way of adding devices that works with minimal human intervention. It has public and private connection interfaces, and the ability to filter content using OpenDNS. It is designed with security in mind, and has low hardware requirements.
