As cybersecurity standards evolve and governance requirements increase, many schools and organisations are doing more than ever to protect their systems. Yet despite this, we continue to see data breaches make headlines, sometimes even in schools with robust programs in place. So where’s the gap?
The missing controls that opened the door to most public data breaches
It turns out that most public data breaches aren’t caused by highly sophisticated tactics or cutting-edge cyber tools. More often than not, they stem from missing or poorly implemented basic controls — the kind that should form the foundation of any cybersecurity strategy.
Five essential practices every school or education provider should review:
1. Multifactor Authentication (MFA)
This helps prevent unauthorised access, even when credentials are phished or compromised. Enable MFA across all available data points – including user identity, location, device, and classification – to reduce the impact of phishing, credential stuffing, and other common attacks.
2. Zero Trust
A ‘never trust, always verify’ strategy that continuously verifies all users, devices, and applications accessing resources. This proactive approach limits access, constantly checks identities and assumes threats can be internal or external, strengthening the protection of data and accounts.
3. Up-to-Date Systems and Software
Keeping systems and software current with an update rollout plan reduces exposure to known vulnerabilities. Apply security patches promptly and decommission outdated platforms to prevent exploitation of unpatched flaws. Automate updates where possible and prioritise critical fixes to strengthen security posture.
4. Antimalware
A key defence against malicious software that can compromise data, disrupt operations, or provide attackers with access. Deploy reputable antimalware across all devices, enable real-time scanning, and update regularly to detect and block emerging threats. Integrate with broader threat detection systems for enhanced protection.
5. Protection of Sensitive Data
Safeguarding critical information helps prevent data loss and exposure of critical information across systems and environments. Classify data based on sensitivity, apply encryption in transit and at rest, and enforce strict access controls. Become familiar with what data you have, where it is stored, and who has access to it.
The Cost of Neglecting the Basics
While advanced cybersecurity solutions are often prioritised, neglecting foundational practices can leave schools vulnerable to 98% of common attacks. These basic measures require fewer resources than dealing with the aftermath of a breach, making them cost-effective for schools of all sizes. These five practices provide baseline protection against most attacks, but outlier threats can still slip through the cracks. Don’t wait for an attack to expose weaknesses in your defences—start with the basics and work your way to comprehensive protection.
Does your cybersecurity management program include these five practices?
