What Is Cisco Network Admission Control (Cisco NAC)?

Cisco Network Admission Control, sometimes called Cisco NAC, functions similarly to a doorman or bouncer at your company's network. Its job is to check who is coming in, ensure they are allowed, and stop people who shouldn't be there from getting in. Consider it this way: you wouldn't let anyone into an exclusive nightclub, would you? You will want to ensure that everyone who enters is either on the guest list or, at the very least, is dressed suitably for the occasion. That is precisely what the Cisco Network Admission Control performs for your network. Cisco Network Admission Control will examine the credentials of all devices attempting to join your network to determine whether or not it is appropriate for them to do so. It validates devices by having them enter things like usernames, passwords, and certificates so that only the appropriate ones are allowed in. Once a device has been granted access, Cisco NAC will monitor it to ensure that it is following the policies and procedures that have been established. Cisco NAC will remove a device from the network if it starts acting strangely, like downloading malware or trying to attack other devices. Cisco Network Admission Control also offers administrators of the network real-time visibility into activities taking place on the network. It's the same as having a spy working for you within the organization, reporting on everything that happens and alerting you if anything appears out of the ordinary. In addition, like a competent doorman, Cisco NAC can adjust its behavior in response to varying conditions. Your network will remain secure even in the face of new dangers if you maintain current Cisco Network Admission Control (NAC) versions. In conclusion, Cisco Network Admission Control is something you need if you want to ensure the safety and security of your network. It is the equivalent of having a highly skilled bouncer at the entrance, verifying everyone's credentials, and ensuring that only the appropriate people are let in. You may relax knowing that the security of your network is being handled competently since Cisco NAC is on the job.
