1. Shellcode is code supplied by an attacker that is often saved in a buffer being overflowed.
2. Traditionally, shellcode transferred control to a user command-line interpreter.
3. Stack overflow variants can target shellcode functions, trusted system utilities, network service daemons, commonly used library code, etc.
4. Buffer overflows are widely exploited, and there are two broad defense approaches: compile-time and run-time defenses.
5. Compile-time defenses aim to harden programs to resist attacks in new programs.
6. Safe coding techniques include auditing the existing code base and using safe libraries.
7. Language extensions and safe libraries can replace unsafe standard library routines.
8. Stack protection mechanisms can add function entry and exit code to check the stack for signs of corruption.
9. Run-time defenses aim to detect and abort attacks in existing programs.
10. Executable address space protection can be done by blocking the execution of code on the stack.
