New agile methods for improving cyber security in companies
It is important that companies identify the material that they need to protect to enable efficient protection. Complex isolated networks are not always as well isolated as you would think. The feasibility study (Toteutettavuustutkimus) conducted by the National Cyber Security Centre Finland (NCSC-FI) successfully tested and developed new, agile and scalable methods for improving these areas.
Key findings:
The cybersecurity of services critical to society can be improved with scalable methods that can be deployed lightly. The companies thought that the pilot methods gave them immediate benefits.
Companies should also invest in monitoring the functionality of production networks’ important information security controls, such as network isolation. The need is illustrated by the finding made in the project, in which 81% of the participant organisations’ networks that were intended to be isolated leaked in unexpected ways.
