Many devastating cyberattacks originate from well-known coding flaws. This episode examines classic vulnerabilities including buffer overflows, SQL injection, and other input-related attacks. We explain how these issues arise, what they allow attackers to do, and how to defend against them using secure coding, bounds checking, input validation, and runtime protections like DEP and ASLR. You'll also learn about real-world incidents that exploited these flaws. For CISSPs, understanding common software weaknesses is critical for conducting risk assessments, reviewing software, and advising development teams.
