Access control

Secure Remote Access for SCADA and OT

Make every remote path known, owned, strongly authenticated, limited, monitored, and removable.

Find every path

Review VPNs, remote desktop gateways, jump hosts, cellular connections, vendor appliances, cloud relays, modems, support tools, and temporary exceptions.

Strengthen identity and approval

Require individual accounts, phishing-resistant MFA where feasible, explicit approval, least privilege, time limits, and rapid revocation.

Constrain the session

Limit source, destination, protocol, tool, duration, transfer capability, and administrative privilege. Avoid direct access from unmanaged endpoints.

Retain useful evidence

Record approvals, identity events, session start and end, commands or activity where appropriate, transferred files, alerts, and exception reviews.
