New UK cyber resilience guidance focuses on protecting essential services

The National Cyber Security Centre has published a new cyber resilience benchmark for organisations providing essential services or supporting critical national infrastructure. The guidance addresses risks including ransomware, supply-chain attacks and disruption to important digital systems.

What has the NCSC published?

On 30 October 2026, the National Cyber Security Centre published its Cyber Assessment Framework Core Profile.

The document establishes a common baseline for assessing cyber resilience across organisations facing moderately sophisticated cyber threats.

It builds on version 4.0 of the existing Cyber Assessment Framework.

The new profile is designed to help organisations understand the security measures needed to protect essential functions and recover from disruptive incidents.

It also supports the development of consistent expectations across sectors.

Why is cyber resilience important for emergency preparedness?

Modern essential services depend heavily on digital infrastructure.

Electricity networks, water suppliers, communications providers and other critical organisations use computer systems to manage operations.

A serious cyber incident could affect an organisation’s ability to deliver services, communicate with customers or restore normal operations.

The NCSC’s guidance recognises several potential threats, including ransomware, compromised suppliers and attacks involving older technology.

It also places importance on the ability to continue essential operations when something goes wrong.

What does the guidance recommend?

The framework covers several aspects of organisational resilience.

These include identifying important systems, managing cyber risks, controlling access, maintaining secure backups and monitoring for suspicious activity.

It also addresses incident response and recovery.

Organisations are expected to understand which systems are essential, how disruption could affect them and what arrangements are needed to restore services.

Testing recovery plans is particularly important.

A backup that has never been tested may not provide the protection an organisation expects.

Does this mean a cyberattack on UK infrastructure is expected?

No.

The publication of cyber resilience guidance is not evidence that a specific attack is imminent.

The NCSC routinely develops guidance to help organisations manage existing and emerging threats.

The new Core Profile is intended to improve preparedness rather than announce an immediate emergency.

What can households learn from this?

Although the guidance is aimed at organisations, some of its underlying principles apply to household preparedness.

Important information should be backed up, essential contact details should be available offline, and households should consider what they would do if internet or telephone services became unavailable.

It is also sensible to maintain alternative ways of receiving information.

Prepper Weekly’s household emergency plan template provides a starting point for documenting important contacts and arrangements.
