secure computer systemsInstalling and using a system is one thing and managing it efficiently with an eye to secure your computer system is quite a different game altogether. Things can get cumbersome pretty easily specially on Linux computers, even more so if you are a new user. There are tons of commands, thousand of locations to look into and a variety of configuration files that you can edit.

Some time back we showed you how you can administer a Linux server using Webmin and a browser Linux System Administration Made Easy with Webmin Linux System Administration Made Easy with Webmin Read More . Let’s look at another tool aimed at something similar, only this time it is a command line tool, albeit the only command you need to remember is “proshield”. ProShield is available for Debian and Debian based distros (think the likes of Ubuntu and Linux Mint Linux Mint: Your Best Choice for a Desktop Linux OS Linux Mint: Your Best Choice for a Desktop Linux OS Read More ).


The installation process for Proshield is a little different than the simple apt-get command that you are used to, simple nonetheless. All you have to do is to download the DEB package and double click on the downloaded DEB file (or if you are so inclined you can also do this via dpkg -i <fullpath of the downloaded deb> inside terminal). All the dependencies will be taken care of automatically and you will have ProShield installed in no time.

ProShield does a lot of heavy lifting for you. Keep in mind that everything that ProShield does to to secure your computer system can be accomplished separately as well, without requiring ProShield at all. However, ProShield looks at a number of important areas of your system to decide if it is secure, up to date and well backed up. If you are a new user, ProShield is great for you as you might not know where to look for the required information and how to resolve the issues. On the other hand, if you are an experienced sys-admin, ProShield can be a valuable addition to your favorite tools that can simplify maintenance and to greatly secure your computer system.

As detailed on ProShield’s webpage it performs some important tasks like helping you in backing up your system weekly, checking for extra root accounts, checking for correct access control permissions, checking to see if apt is fetching only the information that is required, deleting unneeded packages from the local archives, synchronizing the system clock and plenty more.
