Securing Remote OT Operations: Building a Resilient Framework for the Connected Age
- As OT environments become more interconnected, there is a need for a robust security framework tailored to remote OT environments.
- Securing all access points, whether cloud-based, on-premises, or hybrid, ensures safe and reliable operations in any environment.
- To create a resilient and layered defense against evolving threats, security must be consistently integrated throughout the network
- Three-quarters of surveyed companies have already encountered challenges due to OT-targeted cyber-attacks.
- Organizations can reduce potential security risks by restricting remote access to the minimum necessary for each task through the principle of least privilege.
- Establishing secure temporary access is crucial in OT settings, where unique credentials should be used for each session, and access should be promptly removed.
- A resilient security framework for remote OT environments must address the unique conditions and constraints of OT networks, especially where legacy equipment and operating systems are prevalent.
- Securing remote sessions is essential to safeguarding data confidentiality and integrity, particularly for older OT devices that may lack built-in encryption capabilities.
- Integration of IT and OT practices is essential to create effective security postures.
- Learning and education are essential for building a resilient framework, equipped with the knowledge needed to support security goals and avoid actions that might increase risk.
