Access Control
Restricting access to systems, networks, or devices to authorized users only. ORDR enforces access control using device identity and real-time behavior rather than network topology alone.
What is Access Control?
Restricting access to systems, networks, or devices to authorized users only. ORDR enforces access control using device identity and real-time behavior rather than network topology alone.
Access control is one of the oldest and most fundamental principles in security, but its application in modern connected environments has grown dramatically more complex. Traditional access control models — role-based, mandatory, or discretionary — were designed for IT endpoints where installing an agent or configuring authentication software was assumed. In IoT and OT environments, that assumption breaks down entirely.
Thousands of devices on a typical enterprise network — sensors, PLCs, infusion pumps, cameras, HVAC controllers — have no native identity mechanism and cannot participate in directory-based access control. This creates implicit trust: anything on the network can reach anything else, with no enforcement boundary. Attackers exploit this regularly. Once inside a network, lateral movement is trivial when access control doesn't extend to unmanaged assets.
Effective access control in connected environments requires knowing what every device is, what it legitimately needs to communicate with, and enforcing those limits at the network layer — regardless of whether the device itself supports authentication. This shifts control enforcement from the endpoint to the network and to policy engines that understand device identity and behavior.
Key Facts
- The average enterprise has 3–5x more unmanaged devices than managed IT endpoints
- IoT and OT devices account for more than 50% of connected assets in healthcare and manufacturing
- NIST 800-82 and ISA/IEC 62443 both mandate access control for OT environments
- Most ICS breaches exploit the absence of device-to-device access control, not perimeter failures
How ORDR Addresses Access Control
ORDR builds a behavioral baseline for every device and generates least-privilege access control policies based on observed communication patterns. These policies are automatically pushed to network enforcement points — firewalls, NAC, and switches — so that each device can only reach the destinations it legitimately needs, regardless of whether it supports agent-based controls.
