Therefore, you must be very careful to apply Windows security patchesĪnd use a host-based firewall on the ACS Server.

Protect itself from being attacked or from having malicious code loaded on RADIUS for authentication and the Cisco ACS server as your authentication This can be complex and will require some user training. With that, there are some downsides that you If you implement Cisco NAC, you are basically choosing to There are also third-party audit servers that are compatible with the NACįramework, such as the Qualsys Appliance, McAfee While Cisco ACS can do auditing and logging of certain user activities, Is that AV client up-to-date? Another similar Micro OfficeScan solution works with Cisco ACSĪnd the NAC framework to check a user’s posture when it comes to the state of Validation server can have other types of validations and features that ACS This is primarily because the third-party Optionally, the ACS server can send the credentials off to a
The first rule is that the client be healthy and is allowed access to the Write the rules in a way that the most common rule is matched first.

Posture validation rules are a series of polices with multiple rules insideĮach policy. Requesting accesses is checked against the posture validation rules. After that, the Type Length Value (TLV) and posture of the host Next, the ACS Server checks the authentication credentialsĪgainst its own internal database, or Microsoft Active Directory (AD), forĮxample. Hosts and NADs, but also VPN clients and other RADIUS clients. That is because the ACS server is probably not only authenticating NAC Back on the ACS server, there willīe a NAP (network access profile) that determines what to do with the RADIUS The RADIUS request willĬontain VSAs, or vendor specific attributes. To see what the Cisco ACS Web console looks like, check out FigureĬisco’s NAC relies on the RADIUS authorization protocol toĬommunicate the authorization information to ACS. While Cisco ACS plays an important role in the Cisco NAC equation, itĬan do this for many thousands of users without a lot of horsepower. Server needs to be increased in order to support Cisco NAC generally, this is There are some who believe the performance of the Cisco ACS You can extend the Cisco Secure Access Control Server policies byįorwarding credentials to third-party servers. In turn, enforces policy items like antivirus signature file version and OS

That it also implements security policy verification of host credentials. The best part about Cisco Secure Access Control Server is Additionally, you have a choice of downloading access lists and VLANĪssignment to the NAD, to control the PC host. The Cisco Secure Access Control Server judges the state or health of Generally speaking, Cisco Secure AccessĬontrol Server connects with the Cisco Trust Agent to build much of the NACįramework.
Exactly what is this? The short answer is that Cisco ACS isĬisco Secure Access Control Server plays a prominent role inĬisco NAC as a policy decision point. When learning about and implementing Cisco NAC, there are The UNIX version of Cisco ACS has been discontinued. The appliance version is called the CiscoĪCS Solution Engine. You can obtain Cisco ACS in either a Windows However, beginning with ACS version 4.0, CiscoĪCS is performing the same authentication, authorization, and accountingįunctions for networks that are NAC-enabled. Traditionally, this was just needed for dial-up users over modem phone lines What when you logged in and out, as well as what you were granted access to). Figure A shows anĮxample of how Cisco ACS plays a role in the typical network for wireless networkĬisco ACS not only centralizes authentication (who you are)īut also authorization (what you can access) and accounting (the logging of Two major AAA protocols namely, TACACS+ and RADIUS. Cisco Secure Access Control Server supports PIX firewalls, and network access servers. Secure Access Control Server (ACS) to offer authentication, accounting, andĪuthorization services to network devices. When implementing Cisco’s Network Access Control (CNAC). However, today the Cisco ACS server is being used as the central posture server
Typically, you only hear about the importance of the CiscoĪCS server for VPN and dial-up authentication, authorization, and accounting. David Davis explains the role of the Cisco ACS server as part of its NAC solution. Besides being a Cisco NAC AAA server, Cisco ACS also performs AAA for wireless LAN devices, dial-up users, VPN users, and more. The Cisco ACS server is a vital part of Cisco's NAC solution.
