Staff from the sales department have administrator rights to their corporate standard operating
environment, and often connect their work laptop to customer networks when onsite during
meetings and presentations. This increases the risk and likelihood of a security incident when the
sales staff reconnects to the corporate LAN. Which of the following controls would BEST protect
the corporate network?

A.
Implement a network access control (NAC) solution that assesses the posture of the laptop
before granting network access.

B.
Use an independent consulting firm to provide regular network vulnerability assessments and
biannually qualitative risk assessments.

C.
Provide sales staff with a separate laptop with no administrator access just for sales visits.

D.
Update the acceptable use policy and ensure sales staff read and acknowledge the policy.
