"Securing the System" delves into formal methods, a rigorous approach to crafting software free from errors and vulnerabilities. Unlike traditional testing that identifies some bugs, formal methods use the power of mathematics to prove a system behaves exactly as designed. This book explores how formal methods can revolutionize software security by mathematically guaranteeing the absence of critical flaws. By mastering these techniques, you'll build secure systems resistant to cyberattacks, fostering trust and reliability in your software.
