Module description

In this module we introduce you to information security, i.e. how to protect information and information systems against unauthorised access and tampering. Avoiding security breaches has a high priority for all organisations storing and handling confidential data. We will cover technical aspects such as firewalls, access control and cryptography, and organisational issues such as security policies.

The goal of this module is to enable you to learn how to employ technical solutions effectively in an organisation-wide context.
