Securing SCADA networks is the primary goal for any penetration tester on the job. Let's see the following section and learn how we can implement SCADA services securely and impose restriction on it.
Securing SCADA is really a tough job when it is to be practically implemented; however, we can look for some of the following key points when securing SCADA systems:
Keep an eye on every connection made to SCADA networks and figure out if any unauthorized attempts were made
Make sure all network connections are disconnected when not required
Do implement all the security features provided by the system vendors
Implement IDPS technologies for both internal and external systems and apply incident monitoring for 24 hours
Document all network infrastructure and provide individual roles to administrators and editors
Establish IRT teams or red teams for identifying attack vectors on a regular basis
