Designed to build a solid foundation in network security, this course is ideal for beginners and professionals aiming to strengthen their understanding of how networks are structured, secured, and defended.

Course Highlights:

Introduction to Network Security: Understand what network security is, why it matters, and how physical networks, protocols, and security principles form the foundation of secure communication.

Protocols and Fundamentals: Explore how TCP/IP, UDP and ICMP function, and learn how open-source tools like Wireshark and Nmap can be used to analyze and secure network activity.

Application and Transport Security: Learn how to secure data in transit using encryption, protect email systems with PGP and S/MIME and ensure safe browsing through HTTPS, TLS and SSH configurations.

Network Layer Protection: Discover how VPNs and IPsec work to create secure communication channels and protect data traveling across public networks.

Data Link Layer Security: Examine vulnerabilities such as ARP spoofing and MAC flooding and apply defensive techniques in wired and wireless environments using VLANs and WPA3.

Network Access Control: Learn authentication and authorization methods, including RADIUS, TACACS+, ACLs, RBAC and Network Admission Control, to control who can access network resources.

Firewalls and Intrusion Detection/Prevention: Understand different firewall architectures, DMZ configurations and IDS/IPS systems and learn how they protect networks from unauthorized access and malicious activity.

Advanced Network Security Practices: Explore network segmentation, incident handling and security roles, gaining insight into how organizations maintain resilience against evolving threats.

Embark on this learning journey to understand, secure, and defend modern networks, gaining the essential knowledge and skills to protect data, devices, and digital systems.
