Context
Security isn't a feature — it's a foundational property. A single vulnerability can compromise everything else. The review should think like an attacker: where are the weak points? What would I exploit?
Beyond fixing vulnerabilities, consider the security architecture holistically. Is defense-in-depth implemented? Are there single points of failure? Would you trust this system with your own data?
Driving Questions
- What would an attacker target first?
- Where is rate limiting missing or insufficient?
- What attack vectors exist in authentication flows?
- How are secrets managed and what's the rotation strategy?
- What happens when a secret is compromised — is incident response exercisable?
- Where does "security by obscurity" substitute for real controls?
