FireWall KNock OPerator server side - C version

The FireWall KNock OPerator implements an authorization scheme called Single Packet Authorization (SPA), based on Netfilter and libpcap.

Its main application is to protect services such as OpenSSH with an additional layer of security in order to make the exploitation of vulnerabilities (both 0-day and unpatched code) much more difficult.

The authorization server passively listens for authorization packets via libpcap, thus preventing any connections from being processed on the traditional port. Access to a protected service is only granted after a valid encrypted and non-replayed packet is detected.

Tags: Implemented in: Perl, Networking: Server, Role: role::program, security::authentication
