Glacier vault is publicly accessible

Severity: Medium
Service: Glacier
Check ID: GLACIER_PUBLIC

What this check finds

Glacier is a storage service like S3. These vaults are harder to find, but may still contain sensitive information. The resource policy should be locked down to allow access only by certain accounts.

Passing looks like: Glacier vaults are private.

How to fix it

Update the Glacier vault access policy to remove public access and restrict to specific IAM principals.

AWS CLI

aws glacier set-vault-access-policy --account-id - --vault-name VAULT_NAME --policy '{"Policy":"JSON_POLICY"}'

Names in capitals are placeholders for your own resource. Review a command before you run it.

AWS console

S3 Glacier → Vaults → select vault → Edit access policy.

Checked on every scan

KloudLytics runs this check each time it scans a connected AWS account, through a read-only role, and lists every affected resource with its region. On Pro and Business a fix is written for the specific resource rather than the general case above. The exact access it needs
