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.
AntiJOP is an anti-malware solution that recodes assembly language to remove JOP attack gadgets. JOP attacks on x86 often hinge on the availability of 0xFF bytes in preexisting code, which can be co-opted to serve as register-indirect call instructions. AntiJOP removes instances of 0xFF bytes that may exist, for example, in immediate values, MOD/RM bytes, etc.
Multi-OTP is a PHP class that can be used to authenticate and manage OTP user tokens for strong two-factor authentication. It can create, update, and delete tokens to authenticate users with one time passwords (OTP). The users' data are stored in files. The class can also check the user token using several algorithms: Mobile OTP (MOTP), OATH/HOTP (RFC 4226), and OATH/TOTP HOTP Time Based (RFC 4226 extension). It works with compatible software tokens (iPhone, Android, PalmOS, Nokia, and other Java J2ME capable phones) and hardware tokens (such as Feitian, ZyXEL, Authenex, or Seamoon). The multiotp command line utility is also provided, both in "compiled" form (for Windows) and in source code (for Linux or educational purpose). The multiotp command line can be combined with FreeRADIUS (under Linux) or the free TekRADIUS LT (under Windows) in order to have a powerful radius strong authentication server.
GnuTLS is a secure communications library implementing the SSL, TLS, and DTLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols, as well as APIs to parse and write X.509, PKCS #12, OpenPGP, and other required structures. It is intended to be portable and efficient with a focus on security and interoperability.
Whonix is an anonymous general-purpose operating system based on Virtual Box, Debian GNU/Linux, and Tor. By design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location, because Whonix consists of two (virtual) machines. One machine solely runs Tor and acts as a gateway, called Whonix-Gateway. The other machine, Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible.
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.
segatex is a tool to configure SELinux policy with the help of a GUI. At the push of a button, it can generate a .te file in the /usr/share/segatex directory. You can then edit your .te file, make a module, and install. You can make any module name and edit current modules. You can install, update, and remove modules. You can semanage list and semanage login, fcontext, and port or set some domain permissive. You can download SELinux-related RPMs, including xguest, sepostgresql, and mod_selinux. You can download Fedora DVD or CDs. You can relabel your system. You can audit2allow by GUI. You can check refpolicy by analyzer. segatex includes its own policy.
