🎯 Three Subjects Covered
This Cyber Security section covers three MCA Semester III subjects:
1. Cybersecurity Fundamentals & Network Security (CSF & NS)
- Foundation subject — no prior cybersecurity knowledge required
- CIA Triad, attack types, OSI/TCP-IP security layers
- Firewalls, IDS/IPS, VPNs, Zero Trust
- Wireshark, Nmap, Splunk basics
- SOC operations and incident lifecycle
2. Ethical Hacking & Penetration Testing (EHPT)
- Prerequisite: CSF & NS completed or concurrent
- Reconnaissance, scanning, exploitation
- Metasploit, Burp Suite, DVWA
- OWASP Top 10, web app security
- VAPT report writing
3. Digital Forensics & Incident Response (DFIR)
- Prerequisite: CSF & NS completed or concurrent
- Digital evidence, chain of custody, legal framework
- FTK Imager, Autopsy, Volatility
- Windows/Linux/Network forensics
- Incident response lifecycle, forensic reporting

Many topics overlap between the three subjects:
- Wireshark appears in CSF & NS, EHPT, and DFIR
- Splunk appears in CSF & NS and DFIR
- Nmap appears in CSF & NS and EHPT
- Incident lifecycle spans CSF & NS and DFIR
Link freely between subjects — this is the power of Obsidian!
