Network access control, or NAC, solutions support network visibility and access management through policy enforcement on devices and users of corporate networks.
With organizations now having to account for exponential growth of mobile devices accessing their networks and the security risks they bring, it is critical to have the tools that provide the visibility, access control, and compliance capabilities that are required to strengthen your network security infrastructure.
A NAC system can deny network access to noncompliant devices, place them in a quarantined area, or give them only restricted access to computing resources, thus keeping insecure nodes from infecting the network.
NAC solutions help organizations control access to their networks through the following capabilities:
Whether accounting for contractors, visitors, or partners, organizations use NAC solutions to make sure that non-employees have access privileges to the network that are separate from those of employees.
The exponential growth in mobile devices has liberated the workforce from their desks and given employees freedom to work remotely from their mobile devices. NAC for BYOD ensures compliance for all employee owned devices before accessing the network.
IoT devices, whether they be in manufacturing, healthcare, or other industries, are growing exponentially and serve as additional entry points for attackers to enter the network. NAC can reduce these risks in IoT devices by applying defined profiling and access policies for various device categories.
NAC vendors can share contextual information (for example, user ID or device type) with third-party security components. They can respond to cybersecurity alerts by automatically enforcing security policies that isolate compromised endpoints.
As more medical devices come online, it’s critical to identify devices entering a converged network. NAC solutions can help protect devices and medical records from threats, improve healthcare security, and strengthen ransomware protection.
