Abstract
A Unified Threat Management System (UTMS) for securing network traffic in a process control system may comprise network devices configured to receive network traffic related to the process control system and including a ruleset received from an external source. The ruleset may include one or more rules defining a condition to accept or deny the network traffic received at the network device. The state of the network device may be integrated into the process control system as a process control object or variable, thus allowing the state and other UTMS and component network device parameters and variables to be displayed to an operator at a workstation within a graphical process control system environment. The network devices may also communicate with a perpetual service that proactively supplies the devices with rulesets to meet the latest security threats, threat patterns, and control system vulnerabilities found or predicted to exist within the network.
