Course Overview

The Diploma in Network Security is a UK Level 4 qualification lasting nine to twelve months covering practitioner-grade defence of enterprise IP estates. The programme concentrates on firewalls, IDS and IPS, VPNs, NAC, network segmentation, SIEM inspection and packet analysis, and the syllabus is aligned with (ISC)², International Information System Security Certification Consortium guidance and reference materials from ISACA. Delivery is available on-campus in central London, fully online with the same lab and tooling provisioning, or by distance learning, and every route joins the same intake cohort with weekly tutor visibility and named programme-tutor support.

By graduation from the Diploma in Network Security you will be a network security practitioner able to defend a live enterprise estate, with practitioner foundations that map to junior technical roles demonstrated through a portfolio of coursework, applied labs and, at the closing stage, a blend of coursework, applied labs and short applied examinations. Every learner leaves the Diploma in Network Security with a documented body of work suitable for UK employer conversations across SOCs, MSSPs, telecoms security teams and public-sector network defence, and with a clear progression route into the next step of the LSCE ladder. Coursework is scheduled around working professionals so that part-time and full-time routes share the same weekly seminar, the same assessment rubric and the same tutor group.
