📐 Principles
Defense in depth. If one layer fails, the next catches it. WAF ? Network ACL ? App-level auth ? Input validation ? Encrypted storage.
Zero-trust architecture. Every request is authenticated, every input is validated, every output is encoded. Trust no one, verify everything.
Data at rest? Encrypted. Data in transit? TLS 1.3. Passwords? Argon2id. Secrets? Rotated regularly. Keys? Hardware-backed.
Assume you will be breached. Design for detection, containment, and recovery. An incident response plan is not optional.
Manual security checks don't scale. SAST in CI/CD, DAST in staging, secret scanning in pre-commit hooks, dependency auditing in every build.
🧠 Mindset
I think in CIA triad (Confidentiality, Integrity, Availability) for every decision. I balance security with developer experience — I don't say "no," I say "here's how to do it securely."
My goal: Make your applications so secure that attackers move on to easier targets — and give you the compliance evidence to prove it to auditors, customers, and partners.
