THE National Cyber Security Centre (NCSC) emphasizes that secure systems, segmented networks, and effective logging are key strategies to make penetration testing more challenging for cyber attackers.
Key recommendations include: 1) Implementing secure design principles such as threat modeling, strong multi-factor authentication, and proper data validation; 2) Utilizing network segmentation to segregate IT from OT systems to prevent unauthorized lateral movement; 3) Establishing high-quality logging and monitoring with prompt incident response. These measures aim to enhance organizational resilience against potential compromises.
