What are the 3 types of IDS failure?

• A. Catastrophic, major, and partial failure
• B. Critical, major, minor
• C. None, some, all
• D. Hardware, software, human error

Answer: (A)

When assessing IDS failures, focus on how severe the impact is on safety and operation. The three types used here are catastrophic, major, and partial. A catastrophic failure means the IDS is completely nonfunctional or its failure creates an unsafe condition that cannot be tolerated. A major failure signifies a significant degradation in the IDS’s ability to protect or monitor, with substantial impact on performance or safety. A partial failure means only some functions are lost or degraded, while other capabilities remain working. Other options mix different concepts: terms like critical or minor don’t align with the standard three-level severity shown here, and phrases about sources of failure (hardware, software, human error) describe causes rather than how severe the failure is. None, some, all is vague and not a recognized severity scale.
