To address cyberattack for DCS/SCADA system security, organizations need to implement a comprehensive DCS/SCADA system security strategy. This strategy should address the following:
- Segment your network
One of the best ways to protect your SCADA system from cyberattack is to segment your network. This means dividing your network into different zones and restricting access between the zones. This will make it more difficult for attackers to move laterally through your network and gain access to your SCADA system.
- Implement network access control (NAC)
NAC solutions can help you control and monitor access to your SCADA network. NAC solutions can identify devices that are connecting to the network and verify that they are authorized to do so. They can also restrict access to specific resources on the network.
- Use strong passwords and authentication
Use strong passwords for all accounts on your SCADA system, and implement multifactor authentication (MFA) whenever possible. MFA adds an extra layer of security by requiring users to provide two or more factors of authentication, such as a password and a code from a one-time password (OTP) generator.
- Keep your software up-to-date
Software vendors regularly release security patches to fix vulnerabilities in their software. It’s important to install these patches promptly to reduce the risk of your SCADA system being exploited.
- Monitor your network for suspicious activity
Implement security solutions to monitor your SCADA network for suspicious activity. These solutions can detect unusual patterns of traffic and alert you to potential threats.
- Train your staff on security best practices
Your staff is your front line of defense against cyberattacks. Make sure that they’re trained on SCADA security best practices, such as how to identify and report suspicious activity.
