prevents

Use of cryptography requires appropriate cryptographic controls including proper salting, largely mitigating predictable-salt weaknesses.

finds

Security testing in development and acceptance can detect weak password hashing implementations.

prevents

Secure development life cycle includes secure coding practices that would catch predictable-salt usage during design and implementation.

prevents

Application security requirements can specify cryptographic standards that prohibit predictable salts.

prevents

Secure system architecture and engineering principles guide the selection of strong cryptographic mechanisms including proper salting.

prevents

Secure coding explicitly prohibits predictable salts and mandates cryptographically secure random salts.
