Cisco CCNA Service Provider Question of the Week

What is the main security threat to a closed network?

1. A deliberate attack from the outside
2. A deliberate or accidental attack from the inside
3. An employee transmitting sensitive information to someone on the outside
4. An employee getting a virus from a public website

The correct answer is 2.

With a closed network, there is no connection to the outside, therefore any attack from the outside is not an issue.
