Suricata is an Intrusion Detection and Prevention (IDS/IPS) engine developed by the Open Information Security Foundation and its supporting vendors. The engine is multi-threaded and has native IPv6 support, file extraction capabilities, and many more features. It's capable of loading existing Snort rules and signatures, and supports many frontends through Barnyard2.
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.
PolarSSL is a light-weight cryptographic and SSL/TLS library written in C. PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) applications with as little hassle as possible. Loose coupling of the components inside the library means that it is easy to separate the parts that are needed, without needing to include the total library. PolarSSL is written with embedded systems in mind and has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. The source is written to have very loose coupling, enabling easy integration of parts in other software projects. Very loosely coupled cryptographic algorithms for MD2, MD4, MD5, SHA1, SHA-256, SHA-512, AES, Camellia, DES, Triple DES, ARC3, and RSA are included.
DFF (Digital Forensics Framework) is a simple but powerful tool with a flexible module system which will help you in your digital forensics works, including file recovery due to error or crash, evidence research and analysis, etc. DFF provides a robust architecture and some handy modules.
Bukowski Framework is intended to demonstrate that current popular approaches to software security (e.g. DAC, VMA randomization, anti-virus, NIDS, etc.) are not sufficient and that other approaches should be considered more seriously (e.g. MAC, design by contract, mutual authentication/authorization, etc.).
KeePassX is a password manager or or safe that helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk. You only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using AES or Twofish.
PowerBroker Identity Services is an application that joins Linux, Unix, and Mac OS machines to Microsoft Active Directory and securely authenticates users with their domain credentials. Features include: joining non-Windows systems to Active Directory domains in a single step from the command line or from a GUI; authenticating users with a single user name and password; enforcing the same password policies for all platforms; supporting multiple forests with one-way and two-way cross forest trusts; caching credentials in case your domain controller goes down; and providing single sign-on for SSH and Putty. It does not require Active Directory schema changes for installation.
