strongSwan : A complete IPsec and IKEv1 implementation for Linux 2.4 and 2.6 kernels

strongSwan is a complete IPsec and IKEv1 implementation for Linux 2.4 and 2.6 kernels. It also fully supports the new IKEv2 protocol with Linux 2.6 kernels. It interoperates in both IKEv1 and IKEv2 mode with most other IPsec-based VPN products. The focus of the strongSwan project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys on smartcards through a standardized PKCS#11 interface. A unique feature is the use of X.509 attribute certificates to implement advanced access control schemes based on group memberships.

Sshguard monitors services through their logging activit

Sshguard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication.
