What is NAC?
Network Access Control (NAC) is a security solution that controls the access of devices to a network. It ensures that only authorized devices can connect to the network and helps prevent unauthorized access or malicious activity.
How Does NAC Work?
NAC works by authenticating devices attempting to connect to the network, checking their compliance with security policies, and then granting appropriate access based on the results. It often involves the use of agents, probes, or policy enforcement points to enforce security policies.
Benefits of NAC
- Enhanced network security
- Improved visibility and control over network devices
- Protection against unauthorized access and threats
- Compliance with security policies and regulations
Examples of NAC Solutions
Some popular NAC solutions include Cisco Identity Services Engine (ISE), Aruba ClearPass, and Fortinet FortiNAC. These solutions offer features such as device profiling, guest access management, and endpoint compliance checking.
Case Studies
Company A implemented a NAC solution and saw a significant decrease in security incidents related to unauthorized access. The solution helped them enforce security policies and improve network visibility.
Statistics on NAC
A recent study found that organizations that use NAC solutions experience 50% fewer security incidents compared to those that do not. NAC can also help reduce the time and cost associated with security breaches.
