How does high-interaction honeypots differ from low-interaction honeypots?

High-interaction honeypots are designed to closely emulate real systems, allowing them to run actual services and applications. This comprehensive mimicry provides attackers with an experience that is as authentic as possible, which can lead to more valuable data about their tactics, techniques, and procedures. By engaging with genuine applications, high-interaction honeypots can reveal deeper insights into attack vectors and behaviors, enabling security professionals to understand threats more effectively.

In contrast, low-interaction honeypots do not provide the same degree of depth; they typically simulate only basic services and features to lure attackers but do not engage with them in a realistic manner. Instead, they might use predetermined responses and limited interaction capabilities, which, while still useful for gathering intelligence, do not offer the breadth of information that high-interaction honeypots can provide.

The other options do not accurately capture the fundamental differences between high and low interaction honeypots. For instance, high-interaction honeypots might use virtual machines but are not limited to them, and they can be resource-intensive rather than less so.
