Master the course with just 5 Modules

This course guides learners from the basics of network architecture and digital threats to the hands-on implementation of core security measures. Starting with foundational concepts like protocols and vulnerabilities, participants explore tools such as firewalls, intrusion detection systems, and encryption techniques. The journey concludes with practical skills in incident response and proactive defense strategies, empowering learners to secure networks confidently in real-world environments.

Introduction to Network Security Concepts

Overview of network threats, layered defense, CIA triad, attack vectors, security protocols (SSL/TLS, SSH, IPsec).

Firewalls and Access Control

Types of firewalls, stateless vs stateful filtering, NAT, ACLs; hands-on: configuring firewall rules in Cisco Packet Tracer.

Virtual Private Networks (VPNs)

VPN types (IPsec, SSL), tunneling, encryption, authentication; hands-on: site-to-site and remote-access VPN setup simulations.

Intrusion Detection and Prevention Systems (IDS/IPS)

IDS vs IPS, signature-based and anomaly detection; hands-on: simulating network attacks and responses.

Wireshark Lab for Packet Analysis

Capturing and analyzing network traffic; identifying port scans, suspicious payloads, malformed packets, and sniffing behavior.
