pymiproxy is a small, lightweight, man-in-the-middle embeddable proxy capable of performing HTTP and HTTPS (or SSL) inspection. The proxy provides a built-in certificate authority that is capable of generating certificates for SSL-based destinations. Pymiproxy is also extensible, and provides two methods for extending the proxy: method overloading and a pluggable interface. It is ideal for situations where you're in dire need of a proxy to tamper with out- and/or in-bound HTTP data.
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).
MuLaNEO implements algorithms to design and provision resilient multi-layer networks, or hierarchies of technologies (IP/MPLS, Carrier Ethernet, SDH/SONET, etc.). It includes modelling of these technologies, visualizes their interrelations, and allows the dynamic provisioning of the resulting networks on the basis of path computation elements (PCE).
