Which of the following best describes Computer Network Exploitation?

Computer Network Exploitation, often abbreviated as CNE, focuses on the task of gathering intelligence and extracting data from target networks. This involves accessing and collecting information without necessarily disrupting or damaging the system itself. The primary goal is to obtain valuable data that can provide insights into the operations, intentions, and capabilities of adversaries.

The process can encompass various techniques and tools that allow operators to infiltrate networks stealthily, ensuring that the data collection is as unobtrusive as possible. This differs fundamentally from simply disrupting, destroying, or defending against cyber activities, which are distinct operations with separate objectives.

In summary, the definition of Computer Network Exploitation centers around the strategic and covert collection of data to inform decision-making and enhance situational awareness, making it the most appropriate description among the provided options.
