Network Access Control NAC | The advantages to network access control

There are several reasons why using network access control system is advantageous

Due to their pivotal importance when it comes to supplying information within companies and institutions, IT infrastructures are a crucial factor for a company’s success. Vulnerabilities in terms of IT security can quickly lead to data losses or production downtime, ultimately jeopardizing economic success. At companies with high security requirements such as financial or research institutions, the use of network access control is a matter of course. However, SMEs also need to keep track of the location of all devices connected to their network, who they belong to and what types of device they are. The current boom in the number of network-capable devices and employees using their own devices at work has paved the way to increasingly substantial and complex requirements for IT networks.

Even network perimeters are becoming blurred: Employees working remotely need to gain access from outside the network, whereby external servers or guests permit access to the network from within. Network access control aims to minimize the security risks in this environment while simultaneously facilitating user requirements in terms of network access. Network access control systems integrated in an extensive IT security management system assist with checking and ensuring compliance with IT security policies in different operational environments as well as detecting and handling attacks on networks and interferences within the network.

Protect your data and resources against unauthorized access

Network access control substantially increases the security of a company network. It provides transparency with regard to the existing infrastructure and devices that request access to the network. Granular permission allocation enables simpler central management of permissions and prevents malicious users from causing extensive damage. Administrators can take a back seat when it comes to managing end devices, something which can often turn into a full-time job in large networks. Network access control allows you to control access to your network by guests and services providers, and facilitates a secure approach to BYOD. Scope

Support and implementation of your security strategy

Who is allowed to access which service with which device via which access type? With the increasing mobility of employees, the number of diverse types of end devices in the corporate network is growing at the same time. In a security strategy the wifi integration must be defined, to maintain an overview of the network and facilitate its management to a high degree. This has also been shown to reduce operating costs. On the other hand, the end devices should be dynamically assigned to an appropriate network segment depending on the device category, e.g., PC or print.
