Course Overview

This course provides participants with a practical foundation in network security, focusing on protecting network infrastructure, controlling access, identifying threats, and reducing vulnerabilities. It covers essential security technologies and practices, including firewalls, network segmentation, secure protocols, intrusion detection, and traffic monitoring. Participants develop an understanding of common network attacks, security controls, and incident response procedures. The programme emphasizes practical network protection techniques, secure configuration, risk assessment, and continuous monitoring to help organizations maintain reliable, secure, and resilient network environments.

Learning Objectives

  • By the end of the course, participants will be able to:
  • Explain core network security principles and their role in protecting organizational information systems.
  • Identify common network threats, vulnerabilities, attack methods, and potential business impacts.
  • Describe network architectures, communication protocols, and security control mechanisms.
  • Configure fundamental firewall rules and access control policies.
  • Apply network segmentation and secure communication principles to reduce unauthorized access.
  • Explain the functions of intrusion detection and prevention systems.
  • Analyze basic network traffic and security logs to identify suspicious activity.
  • Apply secure configuration and vulnerability management practices to network devices.
  • Describe incident detection, escalation, containment, and recovery procedures.
  • Develop basic recommendations for strengthening network security and maintaining continuous protection.

Who Should Attend

This course is designed for IT professionals, network administrators, system administrators, technical support specialists, junior cybersecurity professionals, and infrastructure engineers who need a solid understanding of network security principles and protective controls. It is particularly suitable for professionals responsible for maintaining network availability, configuring network devices, managing access, and supporting secure IT operations. The programme is also appropriate for IT supervisors, information security officers, technology support teams, and technical staff in government entities, ministries, banks, financial institutions, oil and gas companies, industrial organizations, and large corporations. It is suitable for participants beginning their cybersecurity careers as well as experienced IT professionals seeking to strengthen their network security knowledge. Basic familiarity with computer networks, IP addressing, and common networking protocols is recommended.

Learning Outcomes

  • Describe the main components and principles of a secure network architecture.
  • Recognize common network attacks, including scanning, spoofing, denial-of-service, and unauthorized access attempts.
  • Explain how firewalls, access control lists, and network segmentation help protect network resources.
  • Identify secure network protocols and understand the risks associated with insecure communications.
  • Interpret basic network traffic patterns and security log entries.
  • Recognize indicators of compromise and suspicious network activity.
  • Apply fundamental hardening practices to network devices and infrastructure.
  • Explain vulnerability assessment, patch management, and risk prioritization.
  • Follow established procedures for network security incident reporting and response.
  • Recommend practical measures to improve network protection, monitoring, and operational resilience.

Course Outline

Day 1

Network Security Principles and Threat Landscape

  • Understanding network security objectives: confidentiality, integrity, and availability.
  • Reviewing network architectures, including local area networks, wide area networks, wireless networks, and enterprise networks.
  • Understanding the TCP/IP model, IP addressing, routing, switching, and common network services.
  • Identifying network assets, trust boundaries, entry points, and potential attack surfaces.
  • Examining common network threats, including malware communication, reconnaissance, spoofing, and denial-of-service attacks.
  • Understanding the difference between vulnerabilities, threats, exploits, and security risks.
  • Reviewing defense-in-depth principles and layered network security controls.
  • Establishing basic network security assessment and documentation practices.
  • Practical Exercise: Map a sample enterprise network, identify critical assets and potential attack surfaces, and recommend initial security controls.
Day 2

Firewalls, Access Control, and Network Segmentation

  • Understanding firewall architectures, functions, and deployment models.
  • Reviewing packet filtering, stateful inspection, application-aware controls, and firewall rule evaluation.
  • Developing access control policies based on business requirements and least-privilege principles.
  • Understanding access control lists and traffic filtering across network devices.
  • Designing network segmentation using subnets, virtual local area networks, and security zones.
  • Examining demilitarized zones and the isolation of externally accessible services.
  • Understanding secure remote access and virtual private network fundamentals.
  • Reviewing secure management access and administrative account protection.
  • Practical Exercise: Develop a basic firewall rule set and segmentation plan for an enterprise network, including rules for authorized traffic and restricted access.
Day 3

Network Monitoring, Detection, and Secure Configuration

  • Understanding network monitoring objectives and security visibility requirements.
  • Exploring intrusion detection systems and intrusion prevention systems.
  • Reviewing signature-based and behavior-based threat detection concepts.
  • Interpreting basic network traffic captures, connection records, and security logs.
  • Identifying suspicious connections, unusual traffic patterns, and potential indicators of compromise.
  • Understanding secure protocols, including HTTPS, SSH, and secure remote administration practices.
  • Applying hardening principles to routers, switches, firewalls, and wireless access points.
  • Reviewing firmware updates, patch management, configuration backups, and change control.
  • Practical Exercise: Analyze sample network logs and traffic observations to identify suspicious activity and recommend corrective actions.
Day 4

Vulnerability Management and Network Incident Response

  • Understanding network vulnerability assessment and its role in preventive security.
  • Identifying common configuration weaknesses, exposed services, outdated firmware, and unnecessary access permissions.
  • Reviewing vulnerability scanning concepts and interpreting assessment findings.
  • Prioritizing vulnerabilities according to severity, exposure, exploitability, and business impact.
  • Understanding patch management and secure configuration remediation.
  • Developing network security incident detection, classification, escalation, and reporting procedures.
  • Applying containment principles to suspicious hosts, compromised accounts, and affected network segments.
  • Coordinating network incident response with IT operations, cybersecurity teams, and business stakeholders.
  • Practical Exercise: Review a network vulnerability assessment report, prioritize remediation actions, and develop an incident response plan for a simulated security event.
Day 5

Network Security Implementation and Continuous Improvement

  • Integrating firewalls, segmentation, secure protocols, monitoring, and access controls into a coordinated security approach.
  • Developing network security baselines and configuration standards.
  • Establishing regular reviews of firewall rules, administrative privileges, and exposed network services.
  • Defining monitoring requirements, alert thresholds, and incident escalation paths.
  • Evaluating backup, configuration recovery, redundancy, and network availability requirements.
  • Understanding the relationship between network security, business continuity, and operational resilience.
  • Defining basic network security performance indicators and reporting requirements.
  • Developing improvement plans based on risk assessments, monitoring results, and incident lessons learned.
