### Understanding the DCAF Environment

DCAF offers two main levels of security, which limit users' ability to take over your target workstations. These levels, basic DCAF (or nonsecure) and secure DCAF, offer protection for your workstations to varying degrees. For typical nonsecure environments that deal with nonconfidential information, basic DCAF provides adequate protection. Secure DCAF is more complex and caters to environments, such as banks and insurance companies, that work with confidential material and require greater protection.

In order to be part of the DCAF environment, the workstations must have DCAF components installed.
