Certified Incident Handler (CIH) Practice Ecam

Which characteristic is essential for tools used in OT-based incident response?

1. Ability to handle industrial protocols

2. Compatibility with consumer-grade software

3. Focus on application-layer security

4. Integration with cloud-based services

The correct answer is: Ability to handle industrial protocols

The essential characteristic for tools used in OT (Operational Technology)-based incident response is the ability to handle industrial protocols. OT environments often utilize specialized protocols that govern the operation of machinery and systems within sectors such as manufacturing, energy, and transportation. These protocols include Modbus, DNP3, and PROFINET, which are crucial for controlling equipment and monitoring processes. Tools designed for OT incident response must be adept at understanding and interacting with these industrial protocols to effectively identify, analyze, and mitigate incidents that may disrupt operations. Moreover, since OT systems can be quite different from typical IT environments, the capability to decode and manage these protocols is vital for maintaining the integrity and safety of physical processes. In contrast, compatibility with consumer-grade software, a focus on application-layer security, and integration with cloud-based services are not as pertinent within an OT context. Consumer-grade software may lack the necessary robustness and specific features needed for industrial applications. Application-layer security typically centers on IT components, while cloud-based integration may not be suitable for all OT environments, especially those prioritizing local control and minimal external dependencies.
