What is the purpose of Multi-Layer Security?

Multi-Layer Security, often referred to as defense in depth, aims to create a comprehensive security posture that protects systems and data from various threats. Its core purpose involves deploying multiple security measures at different layers to prevent unauthorized access, particularly to vulnerable systems such as Internet of Things (IoT) devices. This approach ensures that even if one layer of defense is compromised, additional layers remain to thwart potential intrusions, thereby enhancing overall system security.

The choice that highlights preventing unauthorized access to IoT devices directly aligns with the fundamental goal of maintaining security across multiple dimensions and recognizing the particular vulnerabilities associated with IoT devices, which are often targeted by attackers. Instead of relying on a single point of security, this method emphasizes the importance of bolstering defenses to mitigate risks effectively.

The other options, while relevant to technology and security in different contexts, do not directly relate to the primary goal of Multi-Layer Security. Improving user interface design, reducing network latency, and enhancing data storage capacity do not directly contribute to a layered security framework focused on preventing unauthorized access to critical systems.
