It’s hardly ever the main system. More often, it’s a sub-processor — a third-party vendor with access to your data — where policies are loose or outdated, and rotation schedules are ignored.
Password rotation policies for sub-processors are your last defense against stale credentials. Security teams focus on their own accounts, but attackers know that the easiest route is through partners. A strong vendor ecosystem is not only contractual; it’s practical and enforceable.
Start with clear requirements in every sub-processor agreement:
- Minimum password length, complexity, and uniqueness.
- Mandatory rotation intervals, preferably 90 days or less.
- Immediate updates after personnel changes or suspected compromise.
- Audit trails documenting each rotation and policy compliance.
Enforce these rules through regular verifications. API integrations and secure portals can confirm rotation schedules without exposing sensitive data. Don’t take declarations at face value — require evidence such as hashed password change logs, policy configurations, or automated compliance reports.
