Night Owl studying roadmap curriculum

1. Who It Is For

  • Students preparing for Security Engineer, Application Security (AppSec), or Penetration Tester roles.
  • Engineers who want to build hardened systems and audit vulnerability vectors.

2. Core Skills & Competency Matrix

Application Security (AppSec)

OWASP Top 10XSS & CSRF NeutralizationSQL & NoSQL InjectionStatic Analysis (SAST/DAST)Auth & Session Security

Network Defense & Cryptography

Public Key Cryptography (RSA, ECC)TLS 1.3 & Certificate PinningWireshark Packet AnalysisFirewalls & WAFs

Security Operations & Auditing

SIEM (Splunk, Elastic)Incident Response PlaybooksThreat Modeling (STRIDE)Cloud Security Posture (CSPM)

3. Structured Learning Path

1

Cryptographic Primitives & Network Security

Weeks 1–6

Understand asymmetric encryption, digital signatures, hashing algorithms, and protocol security.

Key Topics:Diffie-Hellman key exchangeHMAC message integrityReplay attack defensePacket dissection
2

Application Penetration Testing & OWASP Hardening

Weeks 7–14

Audit vulnerabilities, test input sanitization boundaries, and implement strict Content Security Policies.

Key Topics:DOM-based XSS vectorsJWT signature strippingSSRF exploitation & defenseRate limiting architectures
3

Enterprise Defense, DevSecOps & Incident Response

Weeks 15–20

Integrate security scanning into CI pipelines and configure proactive alerting.

Key Topics:Automated dependency auditingSecret scanningLog tampering preventionBreach containment

4. Verified Capstone Projects

5. Career Lab: Resume Crafting Guidance

  • Feature verified bug bounty disclosures (HackerOne, Bugcrowd) or CVE research if available.
  • Emphasize defensive engineering: show how you mitigated security vulnerabilities rather than just theoretical scanning.

6. Technical Interview Preparation

  • 1.Explain the exact difference between encryption, hashing, and encoding with technical examples.
  • 2.Walk through how you would conduct a threat model for a new mobile banking application.
  • 3.Explain how SameSite cookies and Content Security Policy prevent CSRF and XSS attacks.
