Best Practices of Industrial Control Systems Security
- Monitor Networks: Since linked devices on ICS networks tend to be static and change infrequently, it is imperative to monitor these networks. Setting up a baseline for typical network behavior through ongoing monitoring is essential to improving security.
- Least Privilege: Many ICS protocols don’t have enough access constraints, which might allow unauthorized users to access vital and sometimes dangerous functions. To use ICS protocol-aware firewalls to mitigate this risk, it’s most critical.
- Network Segmentation: Air gaps were formerly a sufficient means of providing security for ICS networks, but they are no longer so. To guarantee the security of equipment not meant for internet access, network segmentation is becoming more and more important.
- Secure Remote Access: To monitor and operate globally dispersed ICS assets, remote access is often necessary. But it’s crucial to make sure that strong encryption, access control, and authentication procedures are in place when establishing this access.
What is Industrial Control System (ICS)?
Industrial control systems (ICS) are a broad word used in manufacturing to refer to integrating network connections, hardware, and software to support vital infrastructure. In the context of critical infrastructure, ICS assets facilitate the efficient administration and operation of crucial services.
Devices for monitoring energy production, distribution, and transmission are among these assets in the power grid. An industrial control system manages production, distribution, handling of products, and manufacturing in the industrial sector.
