Address space layout randomization (ASLR) is an exploit mitigation technique which randomly arranges the address space of key data areas of a process.
Randomly placing virtual memory regions will make it difficult to write memory page exploits as the memory placement will be consistently shifting.
Run the following command and verify output matches:
# sysctl kernel.randomize_va_space kernel.randomize_va_space = 2
Set the following parameter in the /etc/sysctl.conf file:
kernel.randomize_va_space = 2
Run the following command to set the active kernel parameter:
# sysctl -w kernel.randomize_va_space=2
