Seven questions every OT security team should ask before trusting a remote access solution with critical systems 

Remote access is essential to operating and maintaining critical infrastructure. But giving a vendor, contractor, or employee a way to connect is not the same as controlling what they can reach, how long access lasts, or what happens during a session.

Evaluating secure remote access for OT and ICS environments requires looking beyond connectivity, MFA, and session recording. Security teams need to verify individual identity, limit access to authorized assets, protect credentials, govern file transfers, maintain live oversight, and account for every access path, including legacy systems and remote sites.

Use this checklist to evaluate whether a remote access solution can demonstrate seven essential controls for secure, accountable access to critical systems.
