A firewall alone won't stop a determined attacker, and neither will encryption on its own, or a well-written access policy in isolation. Real network protection comes from layering all of them together — so that if one control fails, another is already there to catch the gap.

That layered approach is exactly what British cybersecurity standards expect from serious organisations, and it's what separates networks that merely look secure from networks that actually are.

Arab British Fellowship Training Academy's "Building Multi-Layered Network Defences" course walks participants through every layer of that defence, from network design and access control to encryption, monitoring, incident response and disaster recovery — all aligned with the standards used across the UK.

Who Should Attend?

• Network Engineers integrating security into network infrastructure from the ground up.
• Cybersecurity Analysts and Security Professionals mastering comprehensive network protection.
• IT Managers and Administrators strengthening network security within their organisations.
• Incident Response Teams securing networks against cyberattacks.
• Compliance Specialists tracking UK-specific cybersecurity requirements.

Knowledge and Benefits:

• Apply the core concepts of network security and protection under British standards.
• Build integrated security strategies that protect networks from diverse threats.
• Analyse attack patterns and choose the right defence mechanisms to prevent breaches.
• Combine multiple network security systems into a genuinely layered defence.
• Design incident response plans and strengthen team performance during emergencies.
• Maintain compliance with British cybersecurity regulations and standards.

Module 1: The Threats a Layered Defence Has to Stop

• External and internal threats common in complex network environments.
• How each threat type actually affects systems, data and people.

Module 2: What "Integrated" Security Really Means

• Why combining multiple security methods beats relying on any single control.
• The core components that make up a layered network defence.

Module 3: British Standards Behind the Design

• NCSC Cyber Security Standards and what they expect in practice.
• Building compliance into the network design from day one.

Module 4: Designing the Network for Security From the Start

• Segmenting networks with VLANs, firewalls and isolated zones.
• Using VPNs to separate and protect sensitive traffic.

Module 5: Controlling Who Gets In

• Multi-Factor Authentication and the principle of least privilege.
• Deciding who needs access to what, and reviewing it regularly.

Module 6: Firewalls, IDS and IPS Working Together

• How modern firewalls and intrusion detection/prevention systems complement each other.
• Stopping unauthorised access before it becomes a breach.

Module 7: Encrypting Data in Transit and at Rest

• SSL/TLS, digital signatures and other authentication techniques.
• Where encryption fits into a layered defence strategy.

Module 8: Monitoring the Network Continuously

• Tools for tracking traffic and catching unusual activity early.
• Why continuous monitoring beats periodic checks.

Module 9: Defending Against Advanced Attacks

• Countering APTs, malware and DDoS attacks.
• Patch management and closing vulnerabilities before they're exploited.

Module 10: Responding to and Investigating Incidents

• Rapid response strategies and post-incident analysis.
• Building emergency plans that keep the network running.

Module 11: Running Security at the Enterprise Level

• Structuring security teams and coordinating with external partners.
• Documentation that supports both compliance and legal investigations.

Module 12: Protecting Data, Mobile Devices and IoT

• GDPR compliance and safeguarding personal data across the network.
• Securely integrating mobile devices and IoT into enterprise networks.

Module 13: Planning for Disaster Recovery

• Building recovery plans and testing network performance under crisis conditions.
• Keeping systems updated as threats and technology evolve.
