Password Security Best Practices for Operational Technology (OT) Systems
Summary
Hide ▲
Show ▼
Operational Technology (OT) systems, which control critical infrastructure such as energy plants and manufacturing facilities, face unique cybersecurity challenges due to their direct interaction with physical systems. These challenges include outdated hardware, shared accounts, remote access vulnerabilities, and the increasing intermingling of IT and OT systems. Strong password policies are essential to mitigate these risks, as weak passwords can lead to severe consequences, including physical dangers and operational disruptions.
