Cisco NAC Agent
What is Cisco NAC Agent?
Cisco NAC is a network admission control (NAC) system developed by Cisco Systems designed to produce a secure and clean network environment. The system usually installs an application known as the Clean Access Agent on computers that will be connected to the network. This application, in conjunction with both a Clean Access server and a Clean Access Manager, has become common in many universities and corporate environments today. It is capable of managing wired or wireless networks in an in-band or out-of-band configuration mode, and Virtual Private networks (VPN) in an in-band only configuration mode.
Overview
The most used version is 4.9.4.3, with over 98% of all installations currently using this version. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The main program executable is NACAgent.exe. The software installer includes 17 files and is usually about 20.87 MB (21,882,948 bytes).
