Network access control can play a crucial part in any organization in system authentication and network security endorsement

 

Network Access Control (NAC) is an application that employs a specified set of protocols to specify and enforce a policy that describes how to protect access to various computer systems by unauthorized users when they first try to access the network. In simple terms, it is an access control technology that controls access on networks using a firewall or anti-virus protection. It is typically implemented in a private or intranet network. In more complex terms, it can be implemented as a comprehensive security solution for the entire network infrastructure.

The most common devices to use in a private or intranet network access control implementation are routers and edge routers. Moreover, there are also security devices such as intrusion detection devices and firewalls. These devices are used to restrict and prevent access from unauthorized sites. There are several reasons why a company would want to implement this type of security policy in their network infrastructure. For starters, it is important to set up a system that will allow for the collection and recording of information about all of the computers in the organization. This information can then be used for purposes such as incident response, training purposes, or for any other purposes that are defined by the administrator. One example of a technology that is commonly used for ensuring the security of a network is the endpoint security device.

Furthermore, some companies choose to install network access control solutions through the use of what is known as the patch management device. A patch management device is a software program that provides updates to the most recent definitions of security controls, such as those provided by the firewall. These programs are typically installed on individual computers within the organization and are used to scan all computers on a network for potential vulnerabilities. Once these vulnerabilities have been identified, the patch management program will then try to download and install the latest patch available. Once this has been done, the device will then disconnect from the network, allowing the application to continue running while any security-related issues are resolved. Recently, in September 2018, Fortinet launched a new network access control solution for IoT security to offer a response to threats.
