Physical protection is your first line of defence when it comes to securing your premises.

The responsibilities of individuals within the second line of defense vary widely but typically include: • Assisting management in design and development of processes and controls to manage risks. Defining activities to monitor and how to measure success as compared to management expectations.

Train employees to become the first line of defense in the network security risk prevention infrastructure. First, remind them to physically protect devices by not leaving them unattended or in unsecure areas, including locked cars.
