Cyber Threats, Vulnerabilities and Network Defense

Detect Cyber Threats and Defend Networks. Profile threat actors, analyze exploits, capture packets with Wireshark, and scan for vulnerabilities using Nmap. Cyber threats are constantly evolving, and defenders need both threat intelligence skills and hands-on technical abilities to keep up. This course teaches you to identify, analyze, and mitigate modern cyber attacks across enterprise environments. You'll start by profiling threat actors — from nation-states and APTs to insider threats — and analyzing the social engineering tactics and attack vectors they use to gain access. From there, you'll investigate technical exploit mechanics including web application attacks (SQL injection, XSS, CSRF), password cracking methodologies, and cryptographic vulnerabilities, with a hands-on password cracking lab using tools like John the Ripper and Hashcat. The course then moves to network-level defense. You'll capture and analyze live network traffic with Wireshark to detect rogue DHCP servers and ARP spoofing, and classify vulnerabilities across software, hardware, cloud, supply chain, and virtualization layers. Finally, you'll execute Nmap port scans, interpret CVSS severity scores, and design prioritized mitigation plans with defense-in-depth strategies. Every module features a scenario-based role-play with an AI threat intelligence lead, where you resolve realistic red-team findings and make defensive decisions. Who this is for: Junior security analysts, network administrators, and IT specialists aiming to build practical skills in threat intelligence, vulnerability management, and packet-level network defense.
