Network and Information Systems Directive Overview

This document is a guide on the Network and Information Systems (NIS) Directive, which was established by the European Union in 2013 to enhance cybersecurity across member states, including the UK. It outlines the framework's objectives, including reducing cyber risks and improving the cybersecurity posture of essential services and critical infrastructure. The UK NIS Regulations, implemented in 2018, transpose the NIS Directive into UK law, specifying obligations for operators of essential services and digital service providers. The document details the implications of the recent NIS2 Directive introduced in 2023, which expands the scope of critical sectors and introduces stricter compliance measures. It discusses the roles of competent authorities in overseeing compliance and the significance of the Cyber Assessment Framework (CAF) in assessing cybersecurity controls. The document also highlights the potential impacts of NIS2 on UK regulations and the necessity for organizations to prepare for upcoming changes in compliance requirements.
