When you hear the words "security apps", as an end user, one always tend to think of virus scanners, rootkit detectors, firewalls, network tools and so on. And Linux does not have a dearth of these tools which make it one of the most secure if not the most secure OS. Of course, how secure you can make your Linux machine will ultimately depend on your choice of Linux distribution and in what way you configure your machine. You can make your Linux box as open or as closed as you want.
ITSecurity - a website related to security has assembled a list of 103 free security apps. A large number of them are for Windows and Mac users but still, a significant percentage of them for Linux have also made it to the list. The applications have been categorized into 13 categories them being, Spyware, antivirus, rootkit, firewall, email, web utility, network, Intrusion detection system, Virtual private network, temporary files, wireless, encryption and a miscellaneous section.
You won't find Linux applications in all the categories. For example, the spyware category contain only Windows apps ;-). But this is a comprehensive list which lists many applications for Linux that I am aware of for the first time. I thought that ClamAV antivirus was the only antivirus solution for Linux but I was wrong, there are many more. Do check out the full list which will throw light on many applications and then some more which may be of use to all Linux enthusiasts.
