SELinux – SELinux is a flexible mandatory access control program contributed to the Linux kernel by the National Security Agency (NSA). It comes installed on Fedora and Fedora-based distributions, like Linpus Lite. On Linpus Lite, it is disabled by default. If you understand how it works and what you want to do with it, you may enable it from the graphical management interface.
Users and Groups manager – The graphical application used to manage users and groups on Linpus Lite has several physical security features built into it.
One, when you set up a user account, say for a guest, you may opt to enable it to expire at a certain date. Or you may opt to lock the password. With password-locking enabled, the system will insert an extra character (!) in front of the encrypted password, disabling it.
Second, you may choose to enable password expiration.
These are all the security features that you may use to enhance the physical and network security profile of your Linpus Lite-powered computer. If it had support for full disk encryption, you could easily achieve a 5-star physical security rating.
