Checking ASLR and NX in Linux Systems by chuiyewleong is a document available to read on EtoBox.
In exploiting embedded linux system, it is crucial to ensure ASLR and NX features are enabled or not. If both of the features are enabled, then we need to apply ROP with offset comparison technique in creating shellcode to work with the exploit. If any of them is disabled, then it is much simpler to be compromised. For ASLR, it is really simple by checking the user and kernel modules layout in memory before and after the system reboot.
