Rule Description
This rule ensures that Elastic Block Store (EBS) snapshots are not publicly accessible in CloudDefense. EBS snapshots contain the data of an Amazon Elastic Block Store volume and can potentially expose sensitive information if made public. By enforcing this rule, you can protect your data and ensure confidentiality.
Troubleshooting Steps
If you encounter any issues regarding publicly accessible EBS snapshots in CloudDefense, follow these troubleshooting steps:
- 1.
Check EBS Snapshot Permissions: Verify the permissions set for each EBS snapshot. Ensure that their accessibility is limited to authorized users or groups only.
- 2.
Review IAM Policies: Examine the IAM policies assigned to the relevant AWS Identity and Access Management (IAM) roles. Ensure that there are no policies granting public access to EBS snapshots.
- 3.
Audit EBS Snapshots: Regularly audit the EBS snapshots to identify any public snapshots. This can be done using AWS CLI or by utilizing AWS Management Console.
Remediation Steps
To remediate publicly accessible EBS snapshots in CloudDefense, follow these steps:
- 1.Identify Public EBS Snapshots: Use the following AWS CLI command to identify publicly accessible EBS snapshots:
aws ec2 describe-snapshots --owner-ids YOUR_ACCOUNT_ID --query "Snapshots[?not_null(Permissions[?Grantee.URI=='all'] == 'true')]"
This command lists all EBS snapshots owned by your account for further review.
- 1.Modify Snapshot Permissions: Adjust the permissions of each public EBS snapshot by removing the "public" entry. Use the following AWS CLI command to modify snapshot permissions:
aws ec2 modify-snapshot-attribute --snapshot-id YOUR_SNAPSHOT_ID --attribute createVolumePermission --group all --operationType remove
Replace
YOUR_SNAPSHOT_ID- 1.
Automate Remediation: Implement automation to regularly scan and remediate any publicly accessible EBS snapshots. This can be done using AWS Config rules, AWS Lambda functions, or a custom script that periodically checks and modifies snapshot permissions.
- 2.
Monitor for Compliance: Continuously monitor your EBS snapshots to ensure compliance with the policy. Set up alerts or notifications to promptly detect any publicly accessible snapshots and take action accordingly.
By following these steps, you can effectively secure your EBS snapshots in CloudDefense and prevent unauthorized access.
