NIS2 Implementing Regulation

(19) In order to protect the networks of the relevant entities and their information systems against malicious and unauthorised software, those entities should implement controls that prevent or detect the use of unauthorised software and should, where appropriate, use detection and response software. The relevant entities should also consider implementing measures to minimize the attack surface, reduce vulnerabilities that can be exploited by attackers, control the execution of applications on endpoints, and deploy email and web application filters to reduce exposure to malicious content.
