🛡️ Defense Mechanisms

ASLR
Randomize memory addresses
DEP/NX
Non-executable stack
Stack Canaries
Detect overflow before return
RELRO
Protect GOT from overwrites
PIE
Position Independent Executable
Safe Functions
strncpy() over strcpy()
Compiler Flags
-fstack-protector-all
Memory-Safe Languages
Rust, Go instead of C/C++
