Security Management Solution

Introducing Moxa‘s MXview as an easy and accessible way to monitor your network security. As ICS networks keep expanding and more networks continue to converge, it is important to understand the benefits of the defense-in-depth approach when designing security architecture. However, having cybersecurity building blocks deployed in an ICS network is not sufficient to completely protect critical assets from unauthorized access.

After determining that the network devices and network topology are secure, a network management policy [Security View]  needs to be established to ensure that the network remains secure throughout the entire network lifecycle. To achieve this, system operators should follow a series of guidelines. This will allow them to implement procedures that follow best practices to ensure that secure monitoring and management of the network take place as smoothly and reliably as possible.

According to a report published by ICS-CERT, a sound security management model should include the following stages:

• Identify and secure network connections in the ICS
• Harden network devices
• Manage the human factor
• Continually monitor and assess the network’s security status
• Respond to incidents and get networks back to normal operation quickly

Those with malicious intent can still access the secure network if individuals who use the ICS network do not adhere to the security management model. In order to guarantee that the network has not been compromised, check if the ICS network is following the management principles and ensure that all users have read the guidelines to ensure a more secure ICS network.
