Identity & Access Management
Controlling access to systems using authentication (who you are), authorization (what you can do), and auditing (tracking actions).
- • Multi-Factor Authentication
- • Role-Based Access Control
- • Federated Identity Systems
Introduction to Cybersecurity
Cybersecurity involves protecting systems, networks, and data from digital attacks. This guide provides foundational knowledge covering core concepts, threat models, and practical defenses.
CIA Triad

Key Concepts in Cybersecurity
Common Vulnerabilities
OWASP Top 10 vulnerabilities including injection attacks, broken authentication, and insecure APIs.
- • Regular software updates
- • Security testing (pentesting)
- • Code reviews
Common Cyber Threats
Malware & Ransomware
Malicious software that compromises systems or holds data hostage.
Phishing Attacks
Social engineering attacks to steal credentials or install malware.
Distributed Denial
Overwhelming systems with traffic to disrupt services.
Defense Strategies
Layered Security
Multiple security measures working in concert to reduce attack surface.
Incident Response
Prepared plan for identifying, containing, and recovering from breaches.
Security Awareness
Educating users to recognize threats like phishing attempts.
Industry Best Practices
Security by Design
- • Integrate security throughout development lifecycle
- • Principle of least privilege
- • Fail-safe defaults
Continuous Monitoring
- • Real-time threat detection
- • Log analysis & correlation
- • Security Information Event Management (SIEM)
