Operational technology plays a very vital role in every organization. How can companies protect it?
FREMONT, CA: Over the past few years, cyberattacks are increasing, and threat actors are continually evolving at an exponential rate and looking for easy access. Since IT boundaries are strengthening, building control systems generally provide a path of less resistance to these cyber threats. In conventional IT, the main focus is eliminating risk and solving problems, but in operational technology, enterprises usually don’t know what problems and risks exist. It is crucial for enterprises to determine what they know and identifies where their operational technology (OT) vulnerabilities still exist.

There
are some essential, cost-effective solutions that hold the potential of going a long way in increasing control system security.
• Inventory and assessment: The majority of enterprises don’t possess the knowledge of how to control the system, contractors, and connectivity present in their portfolio, which makes the basic remediation cumbersome, if not impossible. Enterprises should initiate an IT/OT assessment for recognizing connected devices to get the baseline of all the connected devices in the network.
• IT solutions: Enterprises should place devices that are publicly exposed behind a firewall or secure gateway device equipped with a facility management-owned and controlled remote access solution. Moreover, businesses should also implement explicit users with role-based access. Besides, vendor access needs to be controlled through policy and enforcement.
• Vendor Management 2.0: Policy should be created not only for remote access, but also configuration, system setup, and backup of all control systems and auditing is also necessary. Moreover, it is vital to incorporate threat monitoring designed and implemented, particularly for OT systems.
• Experienced partner: The enterprises should look for a service provider that is capable of understanding the business goals and can partner with them in securing building control systems.
If followed correctly, the above points can undoubtedly protect the company against a hacker’s attacks since the enterprise continues to enhance its overall operational technology cyber posture.
