    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

    Simple Software-restriction Policy

    Simple Software-restriction Policy

    Control which folders programs can be run from.

    A software policy makes a powerful addition to Microsoft Windows' malware protection. In particular, it is more effective against ransomware than traditional approaches to security. If you know about the Linux 'execute permission' bit then you'll understand what this is for. The mode of operation is somewhat different in that execute permission is granted to folders and subfolders rather than individual files, but the intention is the same, to stop undesirable or unknown software from launching unless you OK it. Additionally, it is possible to specify that certain executables (typically browsers and email clients) are run with reduced rights. This is a valuable damage-limitation measure against browser plugin vulns, etc. The protection can be turned off without a reboot whilst installing legitimate software, and will automatically reactivate after a specified time

    A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

    The OVAL Interpreter is a freely available reference implementation that demonstrates the evaluation of OVAL Definitions. Based on a set of OVAL Definitions the interpreter collects system information, evaluates it, and generates a detailed OVAL Results file. Developed to demonstrate the usability of OVAL Definitions and to ensure correct syntax and adherence to the OVAL Schemas by definition writers, it is not a fully functional scanning tool nor an enterprise scanning tool. It is a simplistic, command-line application that has the ability to execute OVAL Content on an end system. To learn more about organizations that provide OVAL content and tools or otherwise support the OVAL Language, please see the OVAL Adoption Program (http://oval.mitre.org/adoption/).
