Security headers can reduce exposure to framing, content injection and unsafe transport behaviour. Their absence is a configuration signal, not automatic proof that an application is exploitable.
Why it matters
Security headers can reduce exposure to framing, content injection and unsafe transport behaviour. Their absence is a configuration signal, not automatic proof that an application is exploitable.
What to review
- Inspect Content-Security-Policy, Strict-Transport-Security, frame protections and content-type handling.
- Apply policies deliberately; a copied policy can break legitimate scripts, frames or integrations.
- Test representative pages after each change and record exceptions with an owner.
How to interpret the result
Headers are only one layer. They do not replace secure code, authentication, authorization, dependency maintenance or server hardening.
A safe remediation workflow
Confirm the asset owner and change authority first. Apply the change in small, recoverable steps, test service functionality and repeat the check against the same public endpoint. Preserve the evidence and decision rationale when closing the finding.
