Description

Detects AWS OpenSearch domains configured with outdated and insecure TLS protocol versions (TLS 1.0 or TLS 1.1). Using these legacy TLS versions makes the domain vulnerable to known cryptographic attacks and man-in-the-middle exploits.

Detection Strategy

• Scans all OpenSearch domains in the specified AWS region

• Checks the TLSSecurityPolicy configuration for each domain

• Reports a vulnerability if the domain uses Policy-TLS-1-0 or Policy-TLS-1-1

• Each vulnerability includes the domain's ARN and the specific insecure TLS policy being used
