Networking & Operating System Basics
2-3 weeksBuild foundational knowledge of TCP/IP, DNS, HTTP/S, network architecture, and operating system security. Understand how data flows across networks and where vulnerabilities can emerge.
Cryptography & Access Control
2-3 weeksStudy symmetric and asymmetric encryption, hashing, digital signatures, PKI, and certificate management. Learn access control models (DAC, MAC, RBAC) and authentication mechanisms including MFA.
Threats, Attacks & Vulnerability Management
2-3 weeksExplore the threat landscape: malware types, social engineering, web application attacks (OWASP Top 10), and network-based attacks. Learn vulnerability scanning, CVSS scoring, and patch management.
Security Architecture & Defense Technologies
2-3 weeksStudy firewalls, IDS/IPS, SIEM systems, endpoint protection, and Zero Trust Architecture. Learn how to design and implement layered defense strategies for enterprise environments.
Governance, Risk & Compliance (GRC)
2-3 weeksUnderstand security frameworks (ISO 27001, NIST CSF), regulatory requirements (GDPR, HIPAA, PCI DSS), risk management methodologies, security policies, and audit processes.
Incident Response & Security Operations
2-3 weeksLearn the incident response lifecycle, digital forensics basics, log analysis, threat intelligence, and security operations center (SOC) workflows. Practice with tabletop exercises and simulated incidents.
Penetration Testing & Advanced Topics
3-4 weeksStudy ethical hacking methodologies, penetration testing tools (Nmap, Burp Suite, Metasploit), cloud security, DevSecOps, and emerging topics such as AI-driven threats and quantum-safe cryptography.
