Effective patch management and backing up of systems is an important element of not only operational resilience but also a comprehensive security program for industrial control systems (ICS).
A well-thought-out backup plan for the entire control system is recommended. A thorough backup plan considers the following factors.
We can help to perform a backups (and verification where applicable) of your Servers,
Workstations, PLCs, HMI Panels, Drives, Network Switches etc. and store the associated programs and configuration files in an agreed repository.
We recommend having multiple backup repositories to mitigate the risk that your repository is corrupt. If your security policies permit backups to be held off-site then we are also able to include for this within our service.
