RECYCLEBIN controls (2)
CTL.RECYCLEBIN.EBS.RETENTION.001
Recycle Bin Retention Period Below Minimum
- Severity: medium
- Type: unsafe_state
- Domain: exposure
- Compliance: nist_800_53_r5: CP-9, CP-10; soc2: CC6.1;
Recycle Bin retention rule for EBS resources has a retention period below the recommended minimum (7 days). Short retention periods give insufficient time to detect and recover from ransomware or accidental deletion. A 1-day retention period means a Friday deletion is unrecoverable by Monday morning. The retention period should exceed the organization's mean time to detect (MTTD) for data destruction events.
Remediation: Update the Recycle Bin retention rule to at least 7 days. For production workloads, consider 30 days to ensure detection and recovery time for sophisticated attacks.
CTL.RECYCLEBIN.EBS.VOLUME.001
Recycle Bin Rule Exists for EBS Volumes
- Severity: high
- Type: unsafe_state
- Domain: exposure
- Compliance: nist_800_53_r5: CP-9; soc2: CC6.1;
A Recycle Bin retention rule must exist for EBS volumes. Previously Recycle Bin only supported snapshots; it now supports EBS volumes directly. Without a retention rule, deleted EBS volumes are immediately and irrecoverably destroyed. Recycle Bin is not enabled by default — it must be explicitly configured. Combined with SCP protection (CTL.ORG.SCP.PROTECTRECYCLEBIN.001), this ensures deleted volumes are recoverable and the recovery mechanism itself cannot be disabled by an attacker.
Remediation: Create a Recycle Bin retention rule with resource type ebs:volume. Set the retention period to at least 7 days. Protect the rule from deletion with an SCP denying rbin:DeleteRule and rbin:UpdateRule.
