XPenguins is a program for animating cute cartoons animals in your root window. By default it will be penguins they drop in from the top of the screen, walk along the tops of your windows, up the side of your windows, levitate, skateboard, and do other similarly exciting things.

The last time I wrote about basic “Linux Server Hardening Security” tips. In this post I will write about the /proc/sys/kernel/cap-bound file which act as a powerful Linux hardening tool. This file holds the value of the kernel capability bounding set (expressed as a signed decimal number). This set is ANDed against the capabilities permitted to a process during exec. You can make changes to this file (bit value of cap-bound) and you can restrict many capabilities of process and put restrictions on root related process too. Using capability you can enable or disable Linux kernel modules loading, firewall, routing, raw sockets, locking of memory segments, restrictions on changing file ownership, restrictions on read and search of files and directories, sending signals to processes owned by others, modification of immutable and append-only file attributes, use of chroot(), rebooting the system, conman sys admin tasks such as mount, quotas, swapping and much more.
