Educational institutions should review their security posture on a periodic basis, at least annually, and more frequently if major changes occur—such as the introduction of new systems, regulatory updates, or security incidents. These reviews are not just a compliance exercise, but a way to stay resilient against evolving threats.

It’s also important to recognize that the Information Security Management System (ISMS) should be proportional to the size and complexity of the institution. A small school with a few hundred students will not need the same level of processes, tooling, and documentation as a large university with tens of thousands of students and staff. In other words, the ISMS should grow in scope and depth along with the data volume and the number of people whose information needs to be protected.

In practice:

• Quarterly or semi-annual reviews are advisable for institutions with a larger digital footprint, sensitive research data, or complex IT environments.

• Annual reviews may suffice for smaller schools, provided they are complemented by ongoing monitoring and timely updates when risks change.

By aligning the frequency of reviews with both the threat landscape and the institution’s scale, schools can ensure that their security posture is not only compliant, but also realistic, effective, and sustainable.
