Course Overview

This course equips participants with the knowledge and practical skills required to design secure network architectures and implement effective network segmentation strategies. It focuses on reducing attack surfaces, controlling communication between network zones, limiting unauthorized access, and strengthening protection across enterprise IT environments. Participants explore secure network architecture principles, segmentation models, VLANs, subnetting, access control lists, firewalls, microsegmentation, zero-trust networking, and network access control. The programme also addresses risk assessment, secure traffic flows, monitoring, troubleshooting, and design validation to help organizations build resilient networks that support operational requirements while maintaining strong security controls.

Learning Objectives

  • By the end of the course, participants will be able to:
  • Explain the principles of secure network architecture and defense in depth.
  • Assess network security risks and identify weaknesses in existing network designs.
  • Design network zones and segmentation boundaries based on business and security requirements.
  • Configure VLANs, subnets, and access control mechanisms to separate network resources.
  • Apply firewall rules and access control lists to regulate inter-segment communication.
  • Implement microsegmentation principles to restrict lateral movement within networks.
  • Integrate zero-trust principles into network access and resource protection strategies.
  • Develop segmentation policies for users, servers, applications, operational technology, and sensitive data environments.
  • Validate network segmentation effectiveness through testing, monitoring, and traffic analysis.
  • Establish network design documentation, governance procedures, and continuous improvement practices.

Who Should Attend

This course is designed for network engineers, network architects, cybersecurity professionals, network administrators, infrastructure specialists, and IT security teams responsible for designing, operating, or protecting enterprise networks. It is particularly valuable for professionals involved in network modernization, security architecture reviews, infrastructure transformation, access control implementation, and the protection of critical systems and sensitive information. The programme is also suitable for IT managers, information security managers, security operations personnel, systems engineers, and technical consultants working in government entities, ministries, banks, financial institutions, oil and gas companies, industrial facilities, and large corporations. Participants should have a basic understanding of TCP/IP networking, routing, switching, and common network security controls.

Learning Outcomes

  • Evaluate network architectures against established security design principles.
  • Identify trust boundaries, critical assets, and high-risk communication paths.
  • Develop network segmentation strategies aligned with organizational risk and operational needs.
  • Design VLANs, subnets, security zones, and controlled inter-zone communication.
  • Apply firewall policies and access control lists to enforce segmentation requirements.
  • Explain how microsegmentation can limit lateral movement and contain security incidents.
  • Incorporate zero-trust concepts into network access and resource protection designs.
  • Define appropriate segmentation approaches for corporate IT, cloud environments, and operational technology.
  • Test segmentation controls and interpret network traffic and monitoring results.
  • Produce network security diagrams, implementation plans, and recommendations for ongoing improvement.

Course Outline

Day 1

Secure Network Architecture and Design Principles

  • Understanding secure network architecture and its role in enterprise cybersecurity.
  • Applying defense in depth, least privilege, and secure-by-design principles.
  • Reviewing common enterprise network topologies and architectural models.
  • Identifying network assets, security requirements, trust boundaries, and critical dependencies.
  • Understanding attack surfaces, common network threats, and lateral movement techniques.
  • Assessing existing network architectures for exposure, complexity, and single points of failure.
  • Establishing security requirements for internal, external, remote, and third-party connectivity.
  • Understanding the relationship between network architecture, business continuity, and operational resilience.
  • Practical Exercise: Assess a sample enterprise network diagram, identify security weaknesses, and propose an improved secure network architecture.
Day 2

Network Segmentation Fundamentals and Implementation

  • Understanding network segmentation objectives, models, and security benefits.
  • Designing network zones according to business functions, user groups, applications, and data sensitivity.
  • Reviewing VLANs, subnetting, routing boundaries, and logical network separation.
  • Applying access control lists to restrict communication between network segments.
  • Understanding firewall-based segmentation and controlled inter-zone traffic flows.
  • Establishing segmentation policies for user networks, servers, management systems, and guest access.
  • Evaluating common segmentation mistakes, including overly permissive rules and unnecessary connectivity.
  • Documenting network zones, address spaces, permitted services, and access requirements.
  • Practical Exercise: Design a segmented enterprise network using VLANs, subnets, security zones, and access control rules.
Day 3

Advanced Segmentation, Microsegmentation, and Zero Trust

  • Understanding the limitations of traditional perimeter-based security models.
  • Exploring microsegmentation concepts and methods for controlling east-west traffic.
  • Applying workload-based and application-based segmentation principles.
  • Understanding zero-trust networking and continuous verification of access requests.
  • Integrating user identity, device posture, application context, and access policies.
  • Evaluating network access control approaches for managed and unmanaged devices.
  • Designing segmentation strategies for cloud workloads, virtual environments, and hybrid infrastructures.
  • Understanding the challenges of segmenting legacy systems and interconnected applications.
  • Practical Exercise: Develop a microsegmentation and zero-trust access model for a business application environment, defining communication paths and access restrictions.
Day 4

Segmentation Risk Assessment, Monitoring, and Validation

  • Identifying critical assets and mapping communication dependencies before implementing segmentation.
  • Conducting risk assessments to prioritize high-value systems and sensitive network zones.
  • Analyzing network flows to identify unnecessary access and undocumented dependencies.
  • Establishing monitoring requirements for inter-zone traffic and policy violations.
  • Using network logs and traffic analysis to validate segmentation behavior.
  • Testing permitted and prohibited communication paths against defined security requirements.
  • Troubleshooting routing issues, firewall rule conflicts, and application connectivity problems.
  • Planning controlled implementation, rollback procedures, and business continuity safeguards.
  • Practical Exercise: Analyze a simulated network traffic dataset, identify segmentation gaps, and develop a prioritized remediation plan.
Day 5

Secure Network Design Governance and Final Workshop

  • Establishing standards for secure network architecture and segmentation policy management.
  • Defining responsibilities for network design, security approval, implementation, and review.
  • Managing configuration changes, access exceptions, and policy recertification.
  • Integrating network segmentation with vulnerability management, incident response, and security monitoring.
  • Reviewing segmentation considerations for data centers, cloud environments, remote access, and operational technology.
  • Defining performance, security, and compliance indicators for ongoing network assessment.
  • Developing documentation standards for network diagrams, traffic flows, security rules, and dependencies.
  • Establishing periodic reviews and continuous improvement procedures for evolving network environments.
  • Final Workshop: Design and present a secure segmented network architecture for a complex enterprise environment, including security zones, VLANs, access control policies, microsegmentation opportunities, zero-trust principles, validation procedures, and an implementation roadmap.
