Final answer:
Defense-In-Depth is a strategy that involves implementing multiple layers of security in an IT system, making it a true example of Risk Mitigation. This approach reduces the risk of a threat causing severe damage by ensuring there are multiple defenses in place.
Step-by-step explanation:
The concept of Defense-In-Depth is indeed an example of Risk Mitigation. The main answer to whether Defense-In-Depth is a form of risk mitigation is A) True. Defense-In-Depth involves implementing multiple layers of security controls throughout an IT system. By providing several defensive mechanisms, if one layer fails, the subsequent layers can continue to provide protection.Explanation in more than 100 words: Defense-In-Depth is like having a multi-layered shield in place; it reduces the risk of a threat causing severe damage because there are multiple opportunities to stop the threat before it reaches the core of the system. In the context of the question, Plan B, which represents taking precautionary measures to mitigate potential threats, aligns with the Defense-In-Depth strategy. It's a conservative approach that assumes even if the threat might not be real, the consequences of it being real and not preparing for it would be catastrophic.Conclusion: Defense-In-Depth is a strategic approach in cybersecurity used to protect information by layering defenses. Implementing it is a proactive way of managing security risks that might threaten an organization's data and systems.
