The Viper IDS is an IDS sensor that can be used stand-alone or as an add-on to the Wolverine Firewall and VPN server. It can log all alert information to a remote MySQL database that can be analyzed by applications such as ACID, or can be used with Wolverine to provide real-time responses to potential threats by dynamically adjusting perimeter firewall rule sets. It uses Snort for attack signature detection.
S-terminal lets you create a secure X terminal. Regular X terminals pass unencrypted data between you the remote machine. S-terminal creates an encrypted tunnel through which all X traffic passes. It replaces the remote xdm login screen with a local application that collects username and password, then sets up an ssh tunnel to the remote host and starts a session. It is highly configurable both in appearance and behavior, and deployed S-terminals can be remotely administered. Best of all, it can be added to a KNOPPIX CD to create an instant, bootable, secure X terminal CD.
