Synopsis
When designing an industrial control system, the normal design life can be measured in decades - the Thames Tideway Tunnel project has a design life of 120 years.
There is a large estate of legacy systems that expose the UK’s Critical National Infrastructure to the risk of disruption through offensive Cyber activities conducted by a range of threat actors.
This presentation will introduce the IEC 62443 standard to the audience, with the objective of increasing their knowledge of the multi-layered approach necessary to secure systems that pre-date ‘Cyber Security’. The standard has such breadth that Nick will concentrate on the foundations; how to remotely compile an asset register that allows an organisation to quantify its risk exposure, how to segregate a network in order to limit unauthorised network traversal, what is the difference between segmentation and segregation - and why it is important, the impact to risk presented by the fallacy of an air gapped network, and why VLANs are not a security control (contrary to what IT tell you).
Throughout the presentation there will be real world examples and war stories to provide some light relief to what is a serious subject – the names will be changed to protect the guilty.
