Defense-in-depth is a strategy that uses multiple layers of security to protect an organisation’s assets. Its goal is to stop threats at various stages, even if one line of defense is breached. It includes not only hardware and software, but also people (after all, human error is a leading cause of security breaches).
For many years Mitsubishi Electric has been successful with its defense-in-depth strategy. Cyber security has long been at the core of how we operate and what we produce, and it continues to be so today.
IEC 62443-4-1 certification assures that all factory automation products are manufactured according to secure development lifecycle principles. Certification facilitates cyber security on each level: from early concept to deployment in customer infrastructure and support during everyday operations (including firmware updates).
Mitsubishi Electric also has a very well established PSIRT (Product Security Incident Response Team) to provide you with guidance in case of an incident.
