What UK Schools and Colleges Must Do to Meet the Government’s Cyber Security Core Standard

Cyber attacks on schools and colleges are no longer rare occurrences. They are deliberate, targeted, and increasingly costly. The UK government’s Department for Education (DfE) now sets out a Cyber Security Core Standard that all schools and colleges in England are expected to work towards meeting by 2030. For IT leads, headteachers, and senior leadership teams, understanding what this standard requires is not optional. The consequences of falling short reach far beyond a disrupted school day.

This article breaks down what the standard covers, who it applies to, and where data backup sits at the heart of your compliance journey.

Why the Cyber Security Core Standard Exists

Schools and colleges hold significant volumes of sensitive personal data. Safeguarding records, student outcomes data, staff payroll information, and financial records all sit within your network. A successful cyber incident can make that data inaccessible, compromise it entirely, or expose it to those with malicious intent.

The DfE’s standard identifies the potential consequences clearly: school closure, lasting operational disruption, significant financial loss, reputational damage, and safeguarding failures. These are not theoretical risks. UK schools have experienced ransomware attacks, phishing-led data breaches, and prolonged system outages that have affected students and staff alike.

The standard gives schools and colleges a structured framework for building genuine cyber resilience rather than simply responding to incidents after the fact.

The Six Key Areas of the Standard

1. Annual Cyber Risk Assessments

Schools and colleges must conduct a cyber risk assessment at least once per year and revisit it every term. This assessment should cover hardware, software, data processing activities, staff access permissions, and network infrastructure. It should feed directly into a risk register and a business continuity plan.

Responsibility sits with the Senior Leadership Team (SLT) digital lead, working alongside IT support, the Data Protection Officer (DPO), estate management, and the governing body.

Knowing your risks is the starting point for managing them. Schools that cannot identify where their vulnerabilities lie cannot protect against them.

2. Cyber Awareness for Students and Staff

Informed users are a school’s strongest line of defence. The standard requires schools and colleges to maintain an up-to-date acceptable use policy and deliver regular cyber security training to students, staff, governors, and anyone with a network login.

Training must cover phishing recognition, password security, multi-factor authentication (MFA), social engineering, the physical security of devices, and how to report an incident. For schools covered by the Risk Protection Arrangement (RPA), evidence that staff have completed the National Cyber Security Centre (NCSC) training annually is a condition of cover.

3. Anti-Malware Protection and Firewalls

A correctly configured boundary firewall and up-to-date anti-malware software are non-negotiable requirements. The standard sets out technical expectations for both, including centralised monitoring, scanning of web pages, email attachments and downloaded files, and active alerting when threats are identified.

Security updates to operating systems, firmware, and applications rated as high risk must be applied within 14 days of release. Any vulnerability scoring 7 or above on the CVSSv3 scale falls into this category.

4. User Account Management and Access Controls

Schools hold data that only certain people should be able to reach. The standard requires that accounts are configured so that students and staff access only what they need. MFA must be in place for senior leaders and anyone handling confidential, financial, or sensitive personal data.

Account management processes should cover joiners, leavers, and those changing roles, with termly reviews to remove or adjust access that is no longer appropriate. Global administrator accounts must not be used for routine tasks.

5. Licensed and Updated Digital Technology

Every piece of software, operating system, and application used in a school or college must be properly licensed and receiving security updates. End-of-support dates should be recorded and acted upon. Unlicensed software creates vulnerabilities that attackers actively seek out.

6. Data Backup

The DfE standard is unambiguous on this point. Schools and colleges must back up their data, and they must do it properly.

The NCSC’s recommended approach, endorsed by the DfE, is the 3-2-1 rule: three copies of important data, held on at least two separate devices, with at least one copy stored offsite. For RPA members, meeting this standard is a condition of making a claim following a cyber incident.

Backups must be immutable, meaning they cannot be altered or deleted once created. This protects against ransomware attacks that attempt to encrypt or destroy backup copies alongside live data. Backup plans must be tested termly, with restorations logged and reported. A backup that has never been tested is not a backup you can rely on when it matters most.

Where Backup Fits Into the Bigger Picture

For many schools, the backup standard is the most immediately actionable part of the DfE’s cyber security requirements. It does not require a complete network overhaul or months of policy writing. It requires a clear, tested plan with the right technology in place.

The risks of not having adequate backups are significant. If a ransomware attack locks your systems, your recovery depends entirely on whether your backups are recent, intact, and restorable. Schools that lack off-site, immutable backups face the prospect of paying a ransom, losing data permanently, or spending weeks rebuilding systems from scratch. Any of these outcomes can close a school.

The standard also emphasises that backups should not be device-specific. Data must be recoverable to a wide range of hardware, not tied to a single machine that may itself be compromised or unavailable.

Cloud backup services designed for the education sector meet these requirements by design. Automated daily backups, immutable storage, offsite replication, and tested restore processes are built into the service rather than left to chance.

Covering Microsoft 365 and Google Workspace

One area schools frequently overlook is the backup of cloud productivity platforms. Microsoft 365 and Google Workspace are now central to how most schools operate. However, both Microsoft and Google operate under a shared responsibility model: they protect the infrastructure, but the responsibility for backing up your data sits with you.

Retention policies within these platforms are limited. If a staff member accidentally deletes important records, or if a ransomware attack corrupts your Google Drive or SharePoint, the provider’s built-in recovery options may not be sufficient to restore what you have lost.

Dedicated backup solutions for Microsoft 365 and Google Workspace address this gap, capturing mailboxes, calendars, contacts, SharePoint sites, Teams data, and Drive files on a schedule that your team controls, with restore options that are fast and granular.

Meeting the Standard Is a Process, Not a One-Off Task

The DfE’s cyber security standard is not a checklist to complete once and file away. Risk assessments must be revisited every term. Backups must be tested regularly. Staff training must be renewed annually. Software must be kept current. Policies must reflect how your school actually operates today, not how it operated two years ago.

Schools working towards the 2030 deadline have time to build a structured, realistic roadmap. The NCSC’s Plan Technology for Your School service is a practical starting point for self-assessing where you currently stand.

How BackupVault Supports Schools and Colleges

BackupVault provides UK-based cloud backup services built for organisations that need to protect sensitive data and meet regulatory standards. Our education solutions are designed around the requirements schools face: SFVS compliance, GDPR obligations, and the DfE’s own guidance on data backup and recovery.

We back up Microsoft 365, Google Workspace, and on-premises servers, with immutable, encrypted storage held in UK data centres. Our backup schedules, retention policies, and restore processes are configured to meet the 3-2-1 standard the DfE and NCSC recommend.

If your school needs to close the gap between where it is now and where the cyber security standard requires it to be, data backup is the right place to start.
