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.
PeaZip is a cross-platform file archiver utility that provides a unified portable GUI for many open source technologies like 7-Zip, FreeArc, PAQ, UPX, etc. Creates 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, and ZIP files. It extracts more than 150 archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX, and more. Features of PeaZip include extracting, creating, and converting multiple archives at once, creating self-extracting archives, split/join files, strong encryption with two factor authentication, an encrypted password manager, secure deletion, find duplicate files, calculate hashes, and export job definitions as scripts.
P-Synch is a commercial password management toolkit which provides automated password synchronization, password strength enforcement, password self-reset by authenticated users, and streamlined password reset by helpdesk. P-Synch is available for both internal use as well as for Internet-based deployments in B2B and B2C applications.
SecurityFocus ARIS Extractor is a sophisticated Intrusion Detection System (IDS) log analyzer and reporting system, integrated with the SecurityFocus ARIS web site. It allows administrators to upload Intrusion Detection System (IDS) logs to the SecurityFocus ARIS Web site, producing sophisticated reporting, and research attacks and events. By filtering out insignificant or benign data and converting it to a common (XML) format, ARIS extractor streamlines incident reporting for both security professionals and home users, allowing IDS operators to focus only on relevant attacks and incidents. It allows you to analyze and archive logged incidents, cross reference incidents/attacks with the SecurityFocus Vulnerability Database, look up contact information for offending IP addresses, generate personal incident statistics and reports, automatically identify and report important incidents, reduce the amount of time spent parsing IDS logs, and generate daily summary reports, delivered by email (optional). All of this is done without revealing any information that could be used to discern your identity. It can be configured to obfuscate IP addresses, names, and other pertinent details before submitting them to the ARIS Analyzer web site. It supports Snort, Cisco Secure IDS, Dragon, NetProwler, RealSecure, BlackICE Defender, and ICEPac.
OpenXAdES enables people to work with legally-binding digital signatures (primarily giving and verifying them). Legislation often defines a set of requirements that legal digital signature technologies and infrastructures must be compliant with, and OpenXAdES aims at meeting many, if not all, such requirements from different legislations.
yaspi (Yosi's Anti-Spam POP3 fIlter bot) is a POP3 mail-scanner specifically made to combat mail bombings caused by viruses (i.e. Swen). It connects to the POP3 server, inspects the messages, and deletes the infected ones without ever downloading them. Its most interesting feature is that it can automatically send abuse reports to the ISPs from which the infected mails originated.
MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may also be used in any other domain where efficient large number computations are required. The library supports integer, modular, and floating point arithmetic with practically unlimited precision. It is both speed efficient and highly portable without disregarding code structure and clarity.
