Network security

Learn the fundamentals of securing computer networks against cyber threats. This course covers essential concepts such as network architecture, encryption, firewalls, intrusion detection, and vulnerability management. Ideal for beginners and IT professionals looking to strengthen their understanding of protecting data, preventing attacks, and ensuring secure communications.

This course includes
Module 1: Introduction to Network Security Importance of network security in modern organizations CIA triad: Confidentiality, Integrity, Availability Common network threats and attack vectors Module 2: Networking Fundamentals Review OSI and TCP/IP models IP addressing, subnets, and routing basics Network devices: routers, switches, access points, firewalls Module 3: Security Architecture & Design Secure network topologies (DMZ, segmentation, VLANs) Zero Trust and defense-in-depth strategies Risk assessment and threat modeling Module 4: Cryptography & Encryption Symmetric vs. asymmetric encryption Public Key Infrastructure (PKI) and digital certificates VPNs and secure communication protocols (SSL/TLS, IPSec) Module 5: Firewalls & Intrusion Detection/Prevention Types of firewalls (packet-filtering, stateful, next-gen) IDS/IPS configuration and monitoring Network Access Control

This comprehensive course provides a deep understanding of how to protect and defend computer networks from cyber threats. Participants will explore core security principles, including risk assessment, encryption methods, firewalls, intrusion detection and prevention systems, secure network design, and incident response strategies.


The curriculum blends theory with hands-on practice through labs and real-world scenarios, enabling learners to identify vulnerabilities, configure security tools, and implement best practices to safeguard data and communications. By the end of the course, students will be equipped with the skills to monitor, detect, and mitigate network attacks, and to design robust security policies that meet industry standards—making it ideal for IT professionals, aspiring cybersecurity specialists, and anyone responsible for protecting digital infrastructure.


By the end of this course, learners will be able to: Understand Core Security Principles – Explain key concepts such as confidentiality, integrity, availability, authentication, and non-repudiation. Identify Network Threats and Vulnerabilities – Recognize common cyberattacks (e.g., malware, phishing, DDoS) and evaluate potential risks. Implement Security Measures – Configure firewalls, intrusion detection/prevention systems (IDS/IPS), VPNs, and encryption to protect data and network traffic. Design Secure Network Architectures – Apply best practices for segmenting networks, hardening devices, and creating layered defenses. Monitor and Respond to Incidents – Use security tools to detect breaches, perform basic forensics, and develop incident response procedures. Apply Industry Standards and Policies – Align network security strategies with frameworks such as ISO 27001, NIST, and GDPR compliance requirements. Develop a Security Mindse
