University Cybersecurity: Why Higher Education Is a Target and How to Defend Against It

In the night of 15–16 April 2026, one of Poland’s largest universities lost control of part of its data. A ransomware attack on the University of Warsaw affected — according to the institution itself — approximately 32,800 files, and some documents featuring students found their way to the darknet. The conclusion for the rector and the IT director is uncomfortable. A university is not a random target; it is an attractive target that is often poorly defended.

This article explains why that is and what genuinely reduces the risk.

Why a University Is a Tempting Target

A higher education institution is a trove of personal data on a scale rarely seen outside large organisations: students, applicants, doctoral candidates, current and former employees, academic records, and sometimes valuable research data. Add to this the inherently open culture of academia, the enormous number of users, and — critically for risk — a distributed, decades-old IT infrastructure.

The attack on UW was not isolated. Earlier, a prolonged disruption for students and staff was caused by an attack on the War Studies Academy. National statistics confirm the trend: in 2025 CERT Poland registered a record 260,783 unique incidents, of which 97% were online fraud, and the number of ransomware attacks rose to 179 (up from 147 the previous year).

Distributed Architecture Means a Wider Attack Surface

A mechanism that decision-makers should understand is at work here. The more separate systems an institution runs — student services, email, spreadsheets, e-learning, video — the more entry points, accounts, integrations and places where data lives without unified oversight. Every additional system is not just another contract and another vendor; it is another gateway that someone must guard.

The report “Cybersecurity of the Academic Sector,” produced under the editorship of AGH and under the patronage of the Ministry of Digitalisation, points explicitly to structural shortcomings in Polish universities — including in the area of incident response teams. In other words: the problem is not mere unawareness of threats, but architecture and response capability.

What Actually Reduces Risk

University cybersecurity cannot be bought with a single product; however, a few principles consistently reduce risk and limit the impact of an incident.

• Fewer separate systems. Consolidating processes into a single, controlled environment narrows the attack surface more effectively than adding security layers to more tools.
• Principle of least privilege (RBAC). Roles and permissions limit what an attacker can achieve after compromising a single account.
• Data stored in the EU only. Controlled data location simplifies oversight and compliance.
• Complete event log. An audit trail of operations allows an incident to be detected, contained and explained, and demonstrates due diligence.
• Regular, encrypted backups. These determine whether a ransomware attack means a week’s downtime or restoration from backup.
• Zero-Trust architecture. Assuming that no connection is trusted by default slows an attacker’s lateral movement inside the network.

Security and Compliance Are One Conversation

Operational cybersecurity and legal compliance go hand in hand. A student data breach is simultaneously a security incident and a GDPR violation, reportable to the supervisory authority. That is why access control, EU data location and an event log appear in both contexts; we explore these in the article on GDPR and the AI Act at universities. This is also an argument for consolidation — it is harder to secure and demonstrate compliance for five separate systems than for one environment with unified access control.

How MenToR Addresses This

The MenToR platform was built with security as a shared foundation, not an add-on: Zero-Trust architecture, data isolation, processing exclusively in the EU, role-based access control, an event log, and regular encrypted backups. By combining student affairs management (DEAN), teaching and classes into one environment, it reduces the number of separate systems — and therefore the attack surface — rather than expanding it.

Frequently Asked Questions

Why are universities targets for cyberattacks? Because they aggregate personal data on a large scale (students, applicants, staff, academic records), operate in an open academic culture, and maintain a distributed, decades-old IT infrastructure. The more separate systems, the wider the attack surface.

How many cyber incidents were there in Poland in 2025? CERT Poland registered a record 260,783 unique incidents. Online fraud accounted for 97% of these, and the number of ransomware attacks rose to 179, up from 147 the previous year.

How can a university reduce the risk of a data breach? The most effective measures are consolidating processes into a single controlled environment, applying the principle of least privilege (RBAC), storing data in the EU, maintaining a complete event log, keeping regular encrypted backups, and adopting a Zero-Trust architecture. Fewer separate systems means a narrower attack surface.

Is a student data breach a GDPR violation? Yes. A personal data breach is simultaneously a security incident and a GDPR violation, subject to notification to the supervisory authority. That is why operational security and legal compliance are best treated together.
