Building Management Systems and Cybersecurity
Building management systems (BMS) have become crucial components in modern smart buildings, controlling various operations and ensuring efficiency. While BMS can offer significant benefits in terms of streamlining processes and reducing costs, they also pose a substantial security risk if not properly secured. As smart devices, infrastructures, and the Internet of Things (IoT) become more prevalent in BMS environments, the potential for cyber threats increases. Tenable OT Security addresses this gap in BMS security by providing visibility, security, and control to safeguard critical building functions like HVAC, fire safety, and access control.
Enhancing Visibility and Threat Detection
One of the key challenges in securing BMS environments is the diverse nature of assets, including IT and IoT-based systems. Tenable OT Security offers 360-degree visibility to desilo operations and provide a comprehensive view of the entire BMS environment. By employing a hybrid threat detection methodology that combines policy, anomaly, and signature-based technologies, Tenable OT Security can detect threats faster, whether they are known, zero-day, or targeted attacks. This proactive approach helps in identifying and addressing potential security incidents before they impact operations.
Deep Situational Awareness and Vulnerability Management
Tenable OT Security goes beyond traditional network-only detection to offer deep situational analysis of BMS systems, including firmware versions, user access, and ladder logic. This level of insight allows organizations to spot security incidents more effectively and schedule necessary cyber maintenance for BMS assets. Moreover, the intelligent vulnerability management capabilities of Tenable OT Security prioritize vulnerabilities based on a Vulnerability Priority Rating (VPR) to help organizations address the most critical security issues first.
Control and Policy Enforcement
Maintaining control over BMS systems is essential to prevent tampering and unauthorized changes. Tenable OT Security provides centralized tracking and configuration control features to alert organizations of any unscheduled or unauthorized modifications. By defining and enforcing security rules specific to the BMS environment, organizations can automate security policy enforcement and mitigate risks associated with malicious activities or inadvertent changes made by personnel.
Integrated Security Solutions and Future Readiness
Tenable OT Security is designed to work seamlessly with other security systems such as Tenable Security Center and Tenable Vulnerability Management, creating an integrated approach to BMS security. By leveraging existing investments in IT security solutions and fostering collaboration with industry partners, organizations can adapt to evolving cybersecurity challenges and ensure the continuous operation of smart buildings. With a growing market demand for secure and efficient building management systems, Tenable OT Security provides the necessary tools and expertise to safeguard critical infrastructure and ensure business continuity.
