High-confidence secret in SSM String parameter (unencrypted)

Severity: Critical
Service: Secrets exposure
Check ID: SECRETS_SSM_PARAM_HIGH

What this check finds

An SSM Parameter Store parameter of type String or StringList matches a high-confidence credential pattern. String parameters are not encrypted at rest and are readable in plaintext by any IAM principal with ssm:GetParameter.

Passing looks like: No secrets in SSM string parameters.

How to fix it

Convert to SecureString: aws ssm put-parameter --name PARAM_NAME --value VALUE --type SecureString --key-id alias/aws/ssm --overwrite

Compliance controls it is evidence for

A failing result counts against these controls in KloudLytics; a passing one is evidence towards them. How compliance mapping works

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
