Practice principles of least privileges to minimize permissions and accesses to SDM600 related resources. 
Follow security practices defined in SDM600 security deployment guidelines. 
Physically protect process control systems from unauthorized direct access.  
Do not directly connect control systems networks to the internet.  
Separate process control systems from other networks using a firewall system with a minimal number of open ports.  
Process control systems should not be used for internet surfing, instant messaging, or receiving emails.  
Portable computers and removable storage media should be carefully scanned for viruses prior connection to a control system.

For all versions, Hitachi Energy recommends that users apply these general mitigation factors: 

Upgrade the system once a remediated version is available.
Apply Hitachi Energy recommended security practices and firewall configurations to help protect a process control network from attacks that originate from outside the network. Such practices include: 
Physically protecting process control systems from direct access by unauthorized personnel.
Not allowing direct connections to the internet.
Process control systems should not be used for internet surfing, instant messaging, or receiving emails.

Use a firewall system that has a minimal number of exposed ports to separate the process control network from other networks. 
Connection to other networks must be evaluated as necessary. 

Scan portable computers and removable storage media carefully for viruses before connection to a control system.

MSM is not designed nor intended to be connected to the internet. Disconnect the device from any internet facing network.
Adopt user access management and updated antivirus protection engines equipped with the latest signature rules for computers that have installed and are operating the MMS Client application. 
Use the default operating system (OS) user access management function to limit unauthorized access and/or rogue commands via the MMS Client application.
