Understanding RELRO and the Global Offset Table (GOT): A Hands-On Linux Deep Dive
📰 Medium · Cybersecurity
Learn how Linux dynamically links functions and protects them using RELRO and the Global Offset Table (GOT)
Action Steps
- Use GDB to inspect the Global Offset Table (GOT) in a Linux binary
- Configure RELRO to protect the GOT from being overwritten
- Run a Linux binary with GDB to observe how dynamic linking works
- Apply RELRO protection to a vulnerable binary to prevent exploitation
- Compare the differences between a binary with and without RELRO protection using GDB
