Problem
Security notifications are auto-forwarded to external addresses without periodic review.
Solution
Root Cause / Diagnostic:
External auto-forwarding of administrative alerts introduces third-party data leakage and creates single-point-of-failure vulnerabilities outside corporate governance. If the recipient personal inbox or agency email is breached, the attacker gains direct insight into channel security triggers.
Actionable Fix:
1. Eliminate external forwarding configurations in Google Workspace for all administrative and operational accounts.
2. Replace external forwards with internal Google Groups restricted to authenticated corporate domain members with enforced hardware MFA.
3. Establish a quarterly security audit schedule to inspect transport rules and forwarding configurations across all channel administrator mailboxes.
Pro Tip:
Enforce DMARC quarantine/reject policies on your primary domain so that outbound forwarded mail without proper DKIM alignment is flagged and stopped by receiving mail servers.
