Some time ago Dabo I'm talking about grsecurity kernel in which are implemented many security measures.
What is grsecurity?
Grsecurity® is a comprehensive security enhancement for the Linux kernel, defends against a wide range of security threats through intelligent access control, prevents overflow in memory and a number of other problems making it more robust system generally requires no configuration. It has been actively developed and maintained over the past 15 years old.
How do I install
Debian in its unstable as has grsecurity in their repositories is expected in the next stable version already come, Debian-derived distributions such as Ubuntu or Linux Mint will welcome later.
I in the following manual I'll show you how to install debian.
Remind before starting the colors mean in applications and systems
written texts in the command line: Blue
Output in the command line: Green
File names and file content: Brown
First I install debian jessie from the image netinstall
Once the file is installed modified /etc/apt/sources.list and I leave as follows:
deb http://ftp.es.debian.org/debian/ sid main deb-src http://ftp.es.debian.org/debian/ sid main
The rest of the lines and let them change jessie commented by sid order to update the distribution.
Update distribution running the following commands as root:
apt-get update apt-get dist-upgrade apt-get autoremove reboot
install Grsecurity, kernel version may vary to find out what yours I run
apt-cache search grsecurity ....... linux-image-4.4.0-1-grsec-amd64 - Linux 4.4 for 64-bit PCs, Grsecurity protection .......
With this it is which version I need in my case 4.4.0-1
grsecurity installed, replaces the version for yours.
apt-get install linux-grsec-base linux-grsec-source-4.4 linux-grsec-support-4.4.0-1 linux-headers-4.4.0-1-common-grsec linux-headers-4.4.0-1-grsec-amd64 linux-image-4.4.0-1-grsec-amd64
Restart and then to verify that is working grsecurity run:
uname -a Linux aplicacionesysistemas 4.4.0-1-grsec-amd64 #1 Debian Junior grsec201603171922 + 4.4.6-1 + 1 (2016-03-19 x86_64 GNU/Linux
