sessiond allows a cluster of SSL/TLS servers to share their session caches in order to prevent each node of the cluster from negotiating a separate session. SSL/TLS session is basically a set of secret values (symmetric encryption keys, MAC secrets) shared between a client and a server. The use of asymmetric cryptography required to establish new sessions is the main performance bottleneck of the SSL/TLS protocol.
TinyIDS is a distributed intrusion detection system (IDS) for Unix systems. It is based on the client/server architecture and has been developed with security in mind. The client, tinyids, collects information from the local system by running its collector backends. The collected information may include anything, from file contents to file metadata or even the output of system commands. The client passes all this data through a hashing algorithm and a unique checksum (hash) is calculated. This hash is then sent to one or more TinyIDS servers (tinyidsd), where it is compared with a hash that had previously been stored in the databases of those remote servers for this specific client. A response indicating the result of the hash comparison is finally sent back to the client. Management of the remotely stored hash is possible through the client's command line interface. Communication between the client and the server can be encrypted using RSA public key infrastructure (PKI).
sec-wall is a feature-packed security proxy that supports SSL/TLS, WS-Security, HTTP Auth Basic/Digest, extensible authentication schemes based on custom HTTP headers and XPath expressions, powerful URL matching/rewriting, and an optional header enrichment. It's a security wall with which you can conveniently fence otherwise defenseless backend servers.
ThreadFix is a software vulnerability aggregation and management system that reduces the time it takes to fix software vulnerabilities. It imports the results from dynamic, static, and manual testing to provide a centralized view of software security defects across development teams and applications. The system allows companies to correlate testing results and streamline software remediation efforts by simplifying feeds to software issue trackers. By auto-generating application firewall rules, this tool allows organizations to continue remediation work uninterrupted. ThreadFix empowers managers with vulnerability trending reports that show progress over time, giving them justification for their efforts.
