To set the runtime status of the 'kernel.randomize_va_space' kernel parameter,
run the following command:
Parameter:
[don't_use_ASLR/randomize base address for mmap'd areas/ditto, and also randomize the brk base address]
Technical Mechanism:
Address space layout randomization (ASLR) makes it more difficult
for an attacker to predict the location of attack code they have introduced
into a process's address space during an attempt at exploitation. Additionally, ASLR
makes it more difficult for an attacker to know the location of existing code
in order to re-purpose it using return oriented programming (ROP) techniques.
