🎯 Learning paths
Path 1: Cloud Security Engineer (2–4 months)
- Cloud provider security basics — IAM, network, storage
- Container and workload hardening — image scanning, runtime protection
- Detection & response — SIEM, EDR, logging pipelines
- Compliance basics — SOC2, PCI, HIPAA checklist
Outcome: Harden cloud workloads and implement monitoring for production.
Path 2: App & API Security (6–10 weeks)
- OAuth/OIDC fundamentals and secure token flows
- Secure coding and dependency scanning in CI
- Runtime protections — WAF, rate limiting, bot mitigation
Outcome: Build APIs and apps resilient to common attacks.
Path 3: Incident Responder / SIRT (6–8 weeks)
- Logging and telemetry — structured logs, tracing
- SIEM and alerting playbooks (use cases + runbooks)
- Automation with SOAR and post-incident analysis
Outcome: Run an effective security incident response process.
Path 4: Security & Compliance for Startups (4–6 weeks)
- Baseline controls: secrets, MFA, least privilege
- Cost-effective monitoring (open-source SIEM, managed EDR)
- Prepare evidence and automate SOC2 readiness
Outcome: Achieve audit-ready posture without large operational overhead.
📊 Key statistics (snapshot)
- Common topics covered: Identity & Access, Cloud & Infra, App/API Security, Detection & Response, Compliance.
- Practical artifacts: playbooks, checklists, threat model templates, code snippets for secure defaults.
- Typical production targets: MFA enabled, CI secret scanning, CI/CD security gates, automated backup encryption.
