Network Access Control (NAC) vendors


• Definition of Network Access Control (NAC)

Network Access Control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.

• Goals of NAC


▶ Authorization, Authentication and Accounting of network connections
▶ Encryption of traffic to the wireless and wired network using protocols for 802.1X such as EAP-TLS, EAP-PEAP or EAP-MSCHAP
▶ Role-based controls of user, device, application or security posture post authentication
▶ Automation with other tools to define network role
The main benefit of NAC solutions is to prevent end-stations that lack antivirus, patches, or host intrusion prevention software from accessing the network and placing other computers at risk of cross-contamination from viruses and other malware
▶ Identity and access management
Where conventional IP networks enforce access policies in terms of IP addresses, NAC environments attempt to do so based on authenticated user identities or roles
▶ Policy enforcement
NAC solutions allow network operators to define policies, such as the types of computers or roles of users allowed to access areas of the network, and enforce them in switches, routers, and Firewalls/IDS/Load Balancers etc. 


• NAC Vendors 

 

▶ Cisco Identity Services Engine (ISE)

 
Cisco Identity Services Engine (ISE) enables a dynamic and automated approach to policy enforcement that simplifies the delivery of highly secure network access control. ISE empowers software-defined access and automates network segmentation within IT and OT environments.
