IPFC is software and a framework to monitor multiple types of agents in a heterogeneous distributed environment. Agents can implement logging of elements as diverse as packet filters (like netfilter, pf, ipfw, IP Filter, checkpoint FW1, etc.), NIDS (Snort, arpwatch, etc.), Web servers, and other general devices (from syslog-servers to embedded devices). It features log collection for different security "agents", dynamic log correlation possibilities, and easy extensibility due to the generic database and XML message formats used.
The SLAN project is focused on developing a flexible open source Virutal Private Networking system, primarily for securing Internet uplinks which use broadcast media such as 802.11 wireless links or public/shared ethernets. The system is flexible enough to support traditional VPN applications as well. As well as featuring an open design and strong security, the SLAN project hopes to eventually provide support for all major computing platforms.
The sigslot library is a portable, type-safe, thread-safe implementation of the signal/slot paradigm written entirely as a C++ template library. No preprocessor is required. The library can coexist with other C++ libraries, notably the Microsoft Foundation Classes (MFC), adding Qt-like functionality to any suitably instrumented classes. The library should work fine with any reasonably standards compliant C++ compiler that supports the STL and templates with optional template parameters. Partial template specialisation is NOT required.
