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.


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
