8 key software security fails to avoid

CISA’s 'Product Security Bad Practices' highlights eight pervasive AppSec anti-patterns—use of memory-unsafe languages, exposure to SQL and command injection, retaining default passwords, poor open-source stewardship and lack of SBOMs, reliance on deprecated cryptography, skipping default MFA, and failing to publish timely CVEs—and pairs them with concrete mitigations; the guidance also underscores stronger software supply chain security through SBOMs, binary analysis, and reproducible builds to improve transparency and resilience.
