fwknop: Single Packet Authorization and Port Knocking 2.6.9fwknop implements an authorization scheme known as Single Packet Authorization (SPA) for strong service concealment. SPA requires only a single packet which is encrypted, non-replayable, and authenticated via an HMAC in order to communicate desired access to a service that is hidden behind a firewall in a default-drop filtering stance. The main application of SPA is to use a firewall to drop all attempts to connect to services such as SSH in order to make the exploitation of vulnerabilities (bot
The OpenBSD project produces a free, multi-platform 4.4BSD-derived UNIX-like operating system. Emphasizing portability, standardization, coherency, correctness, proactive security and integrated cryptography. It comes with almost 9000 software package in its ports, including a custom X11 environment (Xenocara), desktop environments, web and multimedia applications, compilers and programming languages. It also harbours the OpenBSD-maintained software projects OpenSSH, LibreSSL, OpenIKED, OpenBGPD
