Answer:
security
Step-by-step explanation:

Many times the information that is being transferred is private or even valuable, therefore grabbing the attention of hackers/thief's that want this information. This makes security highly important, but making sure that the information is completely secure is impossible. The best that can be done is adding certain safety measures to secure the information as much as possible, which in term is a technical challenge.
