OWASP Top 10 A02:2021 – Cryptographic Failures Explained for Developers & Security Teams 🔐

Title: OWASP Top 10 A02:2021 – Cryptographic Failures | Complete Breakdown for Developers & Security Teams

Description:
Welcome to another episode in our OWASP Top 10 series!
In this session, we explore A02:2021 – Cryptographic Failures, previously known as Sensitive Data Exposure. This video covers everything from the root causes of cryptographic risks to real-world exploitation techniques and how to implement strong, modern cryptographic controls.

🧩 Topics Covered:

Overview of Cryptographic Failures

Why “Sensitive Data Exposure” evolved into this category

29 CWE mappings including CWE-259, CWE-327, and CWE-331

Attack Scenarios: SQL injection, weak TLS, hash cracking

Prevention Steps: Encryption best practices, HSTS, key rotation, strong algorithms

🔐 Best Practices Mentioned:

Use TLS 1.2+ with Forward Secrecy

Store passwords using bcrypt or Argon2

Replace MD5/SHA1 with SHA-256 or better

Implement secure key management & avoid hardcoded secrets

Validate certificates and avoid insecure crypto modes
