Description

In today's hyper-connected world, Cybersecurity is the most critical discipline for individuals and organizations. Cyber threats, data breaches, and sophisticated attacks pose daily risks to personal privacy, infrastructure, and enterprise assets.

This course equips you with actionable cybersecurity insights, foundational network defense principles, practical vulnerability assessment tools, and real-world countermeasures.

What You Will Learn:

  • Core security principles: Confidentiality, Integrity, and Availability (The CIA Triad).
  • Network architecture, packet sniffing with Wireshark, and port scanning with Nmap.
  • Cryptography, symmetric and asymmetric ciphers, hashing, and digital certificates.
  • Setting up isolated virtual penetration testing labs using Metasploitable.
  • Exploitation frameworks: Metasploit, Searchsploit, and automated vulnerability scanners.
  • Web application security: understanding and preventing SQL Injection and filter bypasses.
  • Social engineering tactics, phishing simulation, malware behavior, and incident mitigation.
  • OSINT tools like Shodan, anonymous web navigation, and cloud security basics.
