Introduction to System and Network Security

Program Overview

This introductory course gives IT staff and new security practitioners a working understanding of how systems and networks are attacked and defended. It covers the CIA triad, common vulnerabilities, secure network design, firewalls and intrusion detection, operating system hardening, identity and access management, encryption basics and security monitoring. Concepts are tied to recognised references such as the CIS Critical Security Controls and to the baseline controls expected by GCC national cybersecurity regulators, so participants can contribute to securing real environments from day one.

Learning Outcomes

• ✓Explain core security principles, including confidentiality, integrity, availability, least privilege and defence in depth.
• ✓Identify common network and system vulnerabilities and the attacks that exploit them.
• ✓Design a segmented network architecture using firewalls, a DMZ and VLANs for a small organisation.
• ✓Apply hardening baselines to Windows and Linux servers and verify them with a checklist.
• ✓Configure basic access controls, including multi-factor authentication and role-based permissions.
• ✓Interpret alerts from firewall, IDS and endpoint logs and escalate suspected incidents.

Target Audience

• System and network administrators
• IT support and infrastructure engineers
• Junior security analysts and SOC trainees
