Network Access Control – 802.1x Protocol

Network access control (NAC); is a solution used to limit or block access by users on the network using  the implementation of the specified security protocols on corporate networks.

Enterprise companies' network infrastructures accommodate a large number of users and devices. Unauthorized access to these network infrastructures in the cyber world brings with it the loss of big data and services. Network access control services provide customized authorizations across corporate network infrastructures, ensuring that sensitive data is accessible only to designated users. Network access control, also called NAC; It determines the authentication, authorization, security control and optimization phases and the authorization of users on the network. These stages, which make access to the network much more controlled, provide effective protection against ZeroDay Attack and similar cyber attacks. It also facilitates the effective and rapid visualization and intervention of risk situations.
Access control, which involves guests and unauthorized persons in a network where they cannot access sensitive data, is also useful in checking that users on the network meet the necessary up-to-date security measures. Offering an advanced and practical security experience for large networks that are becoming increasingly difficult to control, access control is an indispensable cybersecurity service for companies today.
