What does the term "Network Access Control" (NAC) refer to in ForeScout?

The term "Network Access Control" (NAC) in ForeScout refers to policies and practices that are implemented to regulate device access to a network. This includes identifying and authenticating users and devices before allowing them access to the network resources. NAC plays a crucial role in enhancing security by ensuring that only authorized devices meet specific security compliance standards before they can connect to the network. This approach helps in mitigating risks such as unauthorized access and potential threats from non-compliant devices.

The other choices represent different networking concepts that do not directly align with the core principles of NAC. Establishing a guest network pertains to providing controlled access to temporary users, bandwidth management focuses on regulating the data transmission rates of devices, and configuring VPN services is aimed at securing remote connections to a network. While all these aspects contribute to broader network management and security, they do not specifically embody the essence of Network Access Control as defined in ForeScout.
