Security Architecture
Authentication, authorization, encryption, and defense-in-depth patterns for building secure systems that protect data and resist attacks.
Threat Modeling
Systematic identification of threats, attack surfaces, and mitigations using STRIDE and attack trees.
Defense in Depth
Layered security controls so that no single failure leads to full system compromise.
Zero Trust Architecture
Never trust by network location alone — continuous verification for every request.
Identity & Access Management
Managing digital identities, authentication, and authorization at enterprise scale.
Authentication Fundamentals
Verifying identity at scale — passwords, MFA, SSO, passwordless, and session management.
Authorization Models
RBAC, ABAC, ReBAC, and policy-based authorization — choosing the right access control model.
RBAC vs ABAC
Role-Based vs Attribute-Based Access Control — structured comparison of models and use cases.
OAuth2 & OpenID Connect
The industry standard delegation and identity protocols — flows, tokens, and common pitfalls.
JWT Best Practices
Secure JWT issuance, validation, rotation, and anti-patterns to avoid.
API Security
Securing APIs against injection, broken auth, and excessive exposure — OWASP API Top 10.
Encryption Patterns
Protecting data confidentiality in motion and at rest — TLS, AES, envelope encryption.
Secrets Management
Secure storage, injection, and rotation of credentials, API keys, and certificates.
Key Management Systems
Handling cryptographic keys safely with KMS and HSM — rotation, access, and audit.
Network Security
Network segmentation, firewalls, VPCs, and micro-segmentation to limit blast radius.
WAF & DDoS Protection
Defending internet-facing entry points from application-layer attacks and volumetric floods.
Security Headers
HTTP security headers that protect browsers from XSS, clickjacking, and content injection.
Secure SDLC
Embedding security into every phase of the software development lifecycle.
Container Security
Image scanning, runtime security, and least-privilege configuration for containers.
Data Security
Classification, encryption, masking, and access controls to protect sensitive data.
Supply Chain Security
Protecting software provenance — SBOM, dependency scanning, and signed artifacts.
Incident Response
Preparation, detection, containment, eradication, and recovery from security incidents.
Network Segmentation
Separating trust zones with firewalls, VPCs, and micro-segmentation strategies.
Compliance Frameworks
SOC 2, ISO 27001, PCI DSS, HIPAA — compliance controls and implementation patterns.
Security Logging & Auditing
Recording security-relevant actions for accountability, forensics, and compliance.
Encryption at Rest & Transit
TLS configuration, AES key sizes, and envelope encryption patterns.
