Safety and Cybersecurity -- You Can't Have One Without the Other: Page 2 of 2

Security planning needs to include safety. The two can no loner be separate concerns.

Safety and security need to run through the same planning, since security breaches can adversely affect safety. “My point is that many things that apply to safety also increase security and vice-versa,” said Chabroux. “Safety standards have formal methods to verify things. Not so much for security. However, many of these methods do apply to security. So by being judicious, one can increase security and safety at the same time.”

Possibly it is true that keeping a system safe can add to security, and certainly a non-secure system is intrinsically unsafe. But it is undoubtedly quite simple to have a system that is functionally unsafe despite being quite secure. Of course, I am talking about functional safety, the ability to prevent injury or damage to the system, not data safety, the ability to prevent theft or damage to any data.
