Inspector – Network and Information Systems (Cyber Security) – vacancy ref. no. 431496
Make a difference in protecting public health by becoming a Network and Information Systems Inspector.
The Network and Information Systems Regulations (NIS) (2018) extended the original Drinking Water Supply regulations to include greater emphasis on the security and reliability of information systems which control drinking water production or delivery, with particular regard to the modern-day threat of cyber security.
The main responsibility of the DWI NIS team is to ensure that the 17 drinking water companies in England and Wales (that are currently within scope of the NIS regulations) take appropriate and proportionate technical and organisational measures to manage any risks posed to the security of their network and information systems. This includes the cyber and physical security of assets on which their essential service of drinking water provision relies.
The Inspectorate regularly needs to respond to an evolving risk picture, or incidents which impact on the water network. Therefore the post holder will need to be flexible and able to adapt quickly to changing work priorities and may be required to participate in the Inspectorate’s response to a security incident. This may include out of hours working on occasion, but the Inspectorate makes every effort to allow for individual personal circumstances and offers a range of flexible working options including remote working and some working from home.
- Evaluation of annual self assessments by Operators of Essential Service (OES) against the Cyber Assessment Framework.
- Logging and assessment of any reported incidents from the sector.
- Scoping of, preparation for and completion of verification audits with selected OESs.
- Making recommendations regarding any enforcement action that might be required to address gaps in compliance.
- Preparation of new and revision of existing guidance for OES on meeting the requirements of NIS.

- Routine liaison with Inspectorate colleagues, Defra, Welsh Government and OESs.
