Introduction
Schools have become prime targets for cybercriminals, with education ranking among the most attacked sectors globally. From ransomware to phishing, the risks facing schools in 2024 continue to grow. As Multi-Academy Trusts (MATs) and individual schools increase their reliance on digital platforms for learning, administration, and communication, cybersecurity must be a priority.
This article explores the most pressing cyber threats facing schools this year and provides practical steps to mitigate risk.
1️⃣ Ransomware: A Growing Crisis
Ransomware remains the most significant cyber threat to schools, with attacks often crippling entire networks. Cybercriminals target schools because they:
- Store valuable personal and financial data (students, parents, staff).
- Rely on interconnected IT systems that are difficult to restore.
- Often lack dedicated cybersecurity personnel.
📌 Real-World Example
In 2023, several UK schools fell victim to ransomware attacks, with some forced to pay ransom or rebuild systems from scratch after losing access to critical files.
🛡️ How to Defend Against Ransomware:
✔ Regular backups – Keep secure, offline backups of essential data.
✔ Multi-Factor Authentication (MFA) – Protect administrative access.
✔ Staff & student training – Recognise suspicious links and phishing emails.
2️⃣ Phishing: The Gateway to Cyber Attacks
Phishing is the most common attack method used to steal login credentials and gain network access. These emails often impersonate:
- School leadership (Headteachers, IT Managers).
- External suppliers (Exam boards, software providers).
- Government bodies (DfE, Ofsted, HMRC).
📌 The Risk:
If a staff member clicks a malicious link or enters login details into a fake website, attackers can steal credentials, deploy ransomware, or exfiltrate sensitive student data.
🛡️ How to Prevent Phishing Attacks:
✔ Use email filtering tools to detect and block phishing emails.
✔ Train staff and students to spot phishing attempts.
✔ Enable MFA to prevent unauthorised access, even if credentials are compromised.
3️⃣ Data Breaches & GDPR Risks
Schools collect and store vast amounts of personally identifiable information (PII), making them a lucrative target. A data breach could expose:
- Student records (names, addresses, medical histories).
- Staff payroll and HR details.
- Parent contact and financial information.
Under UK GDPR, schools must report breaches to the Information Commissioner’s Office (ICO) within 72 hours, risking hefty fines and reputational damage if non-compliant.
🛡️ How to Reduce Data Breach Risks:
✔ Encrypt sensitive data both in transit and at rest.
✔ Limit access – Ensure staff can only access necessary data.
✔ Regular audits – Check for vulnerabilities and outdated permissions.
4️⃣ Weak or Outdated IT Systems
Many schools still run outdated operating systems and legacy software that no longer receive security updates. This creates:
- Critical vulnerabilities that hackers can easily exploit.
- Incompatibility with modern security tools.
- Slow, inefficient IT systems that disrupt learning.
📌 Common Risks:
- Windows 7/8 still in use (unsupported by Microsoft).
- Old, unpatched school software (e.g., misconfigured student portals).
- Shared passwords across multiple systems.
🛡️ How to Modernise IT Security:
✔ Upgrade to supported operating systems (Windows 11, macOS Ventura, or cloud-based solutions).
✔ Patch software regularly to close security gaps.
✔ Invest in endpoint protection to secure all school devices.
5️⃣ Supply Chain Attacks
Schools depend on third-party IT services, from learning platforms to administration systems. Attackers often compromise suppliers to infiltrate schools indirectly.
📌 High-Risk Vendors Include:
- EdTech providers (student learning platforms, cloud storage).
- Payroll & HR systems (handling sensitive financial data).
- IT contractors (with privileged network access).
🛡️ How to Secure the Supply Chain:
✔ Vet third-party vendors – Demand cybersecurity compliance proof.
✔ Enforce contractual security clauses – Require vendors to notify of breaches.
✔ Limit vendor access – Use role-based access controls (RBAC).
Final Thoughts: Strengthening Cyber Resilience in Schools
Cyber threats against schools will only increase in 2024, but proactive defence measures can reduce risk and safeguard students, staff, and sensitive data.
🔹 Key Actions for Schools:
✅ Implement cybersecurity awareness training for staff & students.
✅ Enforce multi-factor authentication (MFA) across all accounts.
✅ Ensure backups are secure and tested regularly.
✅ Upgrade and patch IT infrastructure to prevent vulnerabilities.
✅ Monitor and manage third-party vendor security risks.
With proper cybersecurity measures, schools can continue to provide safe, uninterrupted learning while staying protected against modern cyber threats.
