ProShield is a security program for Debian Linux. It helps ensure your system is secure and up-to-date by checking many different aspects of your system. Regular use is recommended.
Whether you are a Linux novice or a system administrator with a dozen servers, ProShield is designed to be useable by all. ProShield's main goal is to help secure a newly installed box (computer), as well as maintain the security of an existing box on a maintainance basis.
Some of the main features of ProShield include:
- Helps you backup your system weekly.
- Checks for extra root accounts.
- Checks account & password files for correct access control permissions.
- Makes sure a few security-hazardous packages are not installed.
- Checks to make sure a packet sniffer is not running.
- Removes unneeded packages from the local package archive.
- Checks for new software releases, in order to see if installed software is reasonably up to date. Smart-suggestion to upgrade if an important package is released.
- Checks to see if 'apt' is fetching unnecessary information when checking for software updates.
- Makes sure system time is accurate.
- Checks to make sure the user isn't logged into the system (GUI) as root.
- Checks the configuration of the ssh server ([sshd] if installed) for insecure settings.
- At runtime, ProShield will also check to see if there has been a new version released, and can download and install it at the user's preference.
When the program is done analyzing your system, it displays an "advisory report", and then (if necessary), guides you through a series of interactive questions to help you solve any problems it found.
