Graphical Administrative Applications: All the graphical administrative applications are accessible from System > Preferences, System > Administration, and Applications > System Tools. Most are the same available on any GNOME desktop distribution. One that caught my attention is the Lockdown Editor. As the name implies, it is used to secure several system and application functionalities. The problem with it is access to it is not password-protect, so even if you use it to lock down every available feature, the next person that gains physical access to the system can launch it and unlock them all.
Physical and Network Security Features: Parsix 3.7 lacks any useful physical security features. The installer does not support disk encryption and boot loader password-protection. And by default, the screen is not locked when the screensaver is activated.
On the network security front, there is a graphical firewall application installed, but it is not enabled and configured out of the box. That graphical firewall application is Firestarter. Shown below is its main view, in the enabled state.
Firestarter, by the way, is a host-cum-network firewall application, and provides several security services not available on Gufw or other ufw frontends. Ufw is the command line frontend to IPTables, the firewall management utility in Linux distributions.
Final Thoughts: Parsix is surprisingly a very good desktop distribution. Aside from the issue with a handful of outdated applications, the main problem with it, and the single most important barrier to adoption by more people, is its installation program. That type of installation program does not belong on a desktop operating system. Not in the 21st century.
Rather than spend more time coding it, I think it would be better to find another distribution’s installer with better features and fork it. If the developers are reading this, YALI, the installation program on Pardus, is a very good candidate. It does not have support for disk encryption, but it should, in one or two more releases.
