This intermediate-level System & Network Security course teaches you to think like an ethical hacker, spotting vulnerabilities, analyzing attacks, and defending infrastructure using real-world tools and techniques.

You'll begin by mastering system hacking methodologies, password attacks, and authentication weaknesses, then dive into malware analysis, exploring viruses, worms, rootkits, Trojans, and today's AI-enabled threats and ransomware-as-a-service models. From there, you'll uncover how network sniffing, ARP poisoning, and honeypot evasion tactics work, and learn how firewalls and intrusion detection systems (IDS) stand up against real attackers. The course also covers endpoint security and network access control, and dives into IoT and OT (operational technology) security, including industrial control systems and HMI-based attacks, so you understand how connected devices and critical infrastructure get compromised. You'll get hands-on with tools like Kali Linux, Nmap, Snort, Shodan, VirusTotal, PEStudio, Ettercap, and Netstat, alongside AI-powered pentesting demos and MITRE ATT&CK-aligned reporting. By the end, you'll have practical, job-ready skills in ethical hacking and network defense, a strong foundation for a career in cybersecurity.

Explore system hacking methodologies, password attack techniques, authentication security, and privilege escalation concepts. Learn how attackers target systems and how security professionals defend against these threats.
