The asset inventory provided by Tenable OT Security provides unparalleled depth of information, including firmware and operating system versions, internal configurations, running software, user details, serial numbers, and backplane configurations for both IT and OT equipment.
4. Risk-Based Vulnerability Management
Leveraging the robust asset tracking functionalities, Tenable OT Security assesses the risk levels of each asset within your ICS network. It generates detailed reports that provide risk scoring and valuable insights, along with recommended mitigation strategies. Tenable vulnerability management is performed using multiple parameters, including firmware versions, relevant CVEs (Common Vulnerabilities and Exposures), proprietary research, default passwords, open ports, installed hotfixes, and other relevant factors. This comprehensive approach enables authorized personnel to immediately identify new vulnerabilities and effectively address risk factors present in the network.
Tenable OT Security compares the current and previous device snapshots to gain better understanding of changes within your OT environment. This includes maintaining a full history of changes made to device configurations over time. Furthermore, you have the capability to roll a device back to its previously confirmed good state.
