Control: Site headers must contain Strict-Transport-Security

Description

The HTTP Strict-Transport-Security (HSTS) response header helps to strengthens your TLS implementation by informing the browser that the site should only be accessed using HTTPS, and any further attempts to access the site using HTTP should automatically redirect to HTTPS. These countermeasures help prevent Man-in-the-middle attacks as well as other attacks such as Session Hijacking.

Usage

Run the control in your terminal:

steampipe check net_insights.control.security_headers_strict_transport_security

Snapshot and share results via Steampipe Cloud:

steampipe login
steampipe check --share net_insights.control.security_headers_strict_transport_security
