1.5.3 Ensure address space layout randomization (ASLR) is enabled - /etc/sysctl.conf, /etc/sysctl.d/*
Information
Randomly placing virtual memory regions will make it difficult to write memory page exploits as the memory placement will be consistently shifting.
Solution
Set the following parameter in the /etc/sysctl.conf or a /etc/sysctl.d/* file: kernel.randomize_va_space = 2 Run the following command to set the active kernel parameter: # sysctl -w kernel.randomize_va_space=2
