Synopsis

Permissive HTTP Strict Transport Security Policy Detected

Description

HTTP Strict Transport Security (HSTS) is an optional response header that can be configured on the server to instruct the browser to only communicate via HTTPS.

The detected HSTS policy doesn't have long max-age value which is a representation (in milliseconds) determining the time in which the client's browser will adhere to the header policy or it doesn't cover subdomains via includeSubDomains directive.

Solution

The max-age must be set at least to 31536000 seconds (1 year) and includeSubDomains directive must be specified.
