Posted on Sunday March 13, 2016 by Eric Potvin
You might need to protect your system against fork bomb attacks. A simple way to prevent this is by setitng up processes limit for your users. All the limits can be configured in the
sudo vi /etc/security/limits.conf
This file comes with all the help you need. Here's an example:
user1 hard nproc 100 @group1 hard nproc 20
This will prevent users from a specific group from having a maximum of 20 processs and maximize the number of processes to 100 to user1.
