Ubuntu Linux: Turn On Exec-Shield Buffer Overflow Protection

by on May 19, 2013 · 3 comments

I am trying to set exec-shield protection on Linux as described here but getting the following error on Ubuntu Linux server version 12.04 LTS:

sysctl -w kernel.exec-shield=1
error: “kernel.exec-shield” is an unknown key

How do I fix this problem and make sure exec-shield buffer overflow protection security feature turned on Ubuntu Linux?

Now that I have Cent OS (RHEL clone) installed on my IBM server, I’m wondering what is ExecShield and how do I disable the same?
