Cybersecurity — Master Hub (defend + attack + operate)
Secure web/app systems like a senior application-security/AppSec + offensive-security engineer: prevent, detect, and respond. Defense by construction, verified by testing, run as a program.
Ethics: offensive techniques here are for authorized testing of systems you own or are permitted to test. Never attack third-party systems without written authorization.
How to use this hub
- Start with cybersecurity-foundations (threat model, principles, attack surface).
- Harden the app: OWASP, headers/TLS, auth, secrets/supply-chain.
- Secure the infra: cloud/network; protect the edge: DDoS/WAF/bot.
- Verify with pentesting/vuln-management; run security-operations + compliance.
