The aim of this sub-module is to familiarize small and medium-sized enterprises (users) with their obligations in the event of personal data breach. After reviewing the video and the theoretical part, users will be able to answer questions to check their knowledge. The user will be offered statements, in respect of which he/she will be able to state whether he/she considers them true or false. Once the user has answered the answers, an explanation of the correct answer will appear. If the user achieves a minimum of 80 % correct answers, then the system will generate a certificate as proof of successfully passing the theoretical sub-module.
