Security Engineering & Operations Topics
Operational security practices, secure systems implementation, threat modeling, penetration testing, vulnerability assessment, and security operations at production scale. Covers network security, endpoint security, secure architecture implementation, incident response mechanics, and security automation. Distinct from Security & Compliance (which addresses governance, compliance frameworks, and policy) and from Security Research & Innovation (which addresses novel techniques and research contributions).
Secure Software Delivery: DevSecOps, Pipeline, and Supply Chain Security
Embedding security into how software is built, assembled from dependencies, and shipped. Covers shift-left and secure-SDLC practices, infrastructure-as-code security, CI/CD pipeline and secrets management, integrating security scanning into build and deploy, and configuration and secret management across environments, together with software supply chain security: software composition analysis (SCA), dependency and open-source vulnerability management, build-provenance and artifact integrity, and mitigating supply-chain attack vectors. The 'secure the delivery pipeline and everything it pulls in' discipline, distinct from vendor-risk governance.
Secure Coding and Application Security
Writing and reviewing code that resists attack. Covers the OWASP Top Ten and common web vulnerabilities (XSS, SQL injection, CSRF), input validation, secure coding practices and security code review, static application security testing (SAST), API and HTTP security, database and frontend security, and mobile app security. The application-layer defense discipline for engineers building software.
Identity, Authentication, and Access Management
Designing and operating identity and access control systems. Covers authentication protocols and standards (OAuth, SAML, OIDC, MFA), authorization models (RBAC, ABAC), identity lifecycle and privilege management, IAM architecture and automation, and access control across cloud and on-premises environments. The 'who can do what' control plane, distinct from cryptographic key management.
