Linux Firewalls, 3rd Edition: Greater Security with GrSecurity

Filed under
HowTos

GrSecurity, formally known as Greater Security, is a kernel patch and userspace program for enhancing the security of a Linux system. GrSecurity, also referred to as Grsec, closes some avenues for attack and makes others much more difficult. Grsec implements a sophisticated Access Control List (ACL) for objects in Linux. The ACL can be used to provide much more granular control over files and other resources. For example, using a Grsec ACL, you can control what files will be shown as the result of a find command or which processes are included in process accounting logs.

Grsec also enables a system called PaX to restrict the capability of processes to alter memory space. This aspect alone renders many types of attacks involving overflows completely ineffective. Grsec also provides other protections such as stack randomization to make attacking the computer a more difficult task.

Creating a Unified Ubuntu Experience

On it's own, Ubuntu is a solid desktop Linux experience. It offers ample application choices and it's easy to use. But one area I would like to see greater focus is mirroring one desktop to another. That is, being able to find the same documents and other files I use on both desktop machines. In this article I'll explore options I've found useful in creating a unified Ubuntu Experience.
