Buffer Overflows: Theory and Prevention

Modern DevSecOps (The Hard Way)

Understanding the Low Level

Even though we use high-level tools, understanding how memory corruption works is vital. A Buffer Overflow happens when a program writes more data to a buffer than it can hold.

Prevention in DevSecOps:

  • Use memory-safe languages (Rust, Go) when possible.
  • Use compiler flags like -fstack-protector.
  • Static analysis (SAST) often catches these in C/C++ code.
