What is Cisco Access Control server ACS?
Cisco Access Control Server (ACS) is an authentication, authorization, and accounting (AAA) platform that lets you centrally manage access to network resources for a variety of access types, devices, and user groups.
Is Cisco ACS free?
ACS can be migrated free of charge from an appliance into VM, however it requires purchasing a service/ support contract for the VM.
How do I add a device to Cisco ACS?
From the ACS main menu, click on the Network Configuration button. Click on the Add Entry button. Configure the Domain Name System (DNS) name of the AP, the IP address of the AP, the Remote Authentication Dial-In User Service (RADIUS) shared secret and the authentication method.
What replaced Cisco ACS?
The logical replacement is Cisco ISE.
What is difference between ACS and ISE?
ACS does not have third party profiles and even though third party devices would work, integration is not as easier. Another big difference is that ISE is tightly integrated and is a linchpin for TRUSTSEC deployment to define, manage and push policies/tags etc and is also used for propagation of tags using SXP.
What is AAA client?
An AAA client is a RADIUS or authentication server term for each configured authenticator that is allowed to request authentications for supplicants.
How do I add a device to my Tacacs server?
Start by clicking the left checkbox to enable and then select the dropdown to enter the TACACS settings. Fill out a Shared Secret to be used by the network device when it authenticates a username password to ISE. Next select Enable Single Connect Mode and the underlying Single Connect Support.
Is Tacacs secure?
TACACS+ provides security by encrypting all traffic between the NAS and the process. Encryption relies on a secret key that is known to both the client and the TACACS+ process.
Is Cisco smartnet mandatory?
Our technical support company says it's required to have a Smartnet license to be able to upgrade the network to the latest firmware. The answer to this question is both a yes and a no. A valid Service Contract is needed to download firmware files from the Cisco website.
What does ACS stand for in networking?
What Does Access Control System (ACS) Mean? An access control system (ACS) is a type of security that manages and controls who or what is allowed entrance to a system, environment or facility. It identifies entities that have access to a controlled device or facility based on the validity of their credentials.
What is the difference between Radius and TACACS+?
RADIUS was designed to authenticate and log remote network users, while TACACS+ is most commonly used for administrator access to network devices like routers and switches.
What is access control server?
What is Access Control Server. Access Control Server (ACS) is in the issuer domain (banks) of 3-D Secure protocols. An ACS which is used to support cardholder authentication is required to be maintained by each card issuer.
Overview
This chapter contains an overview of Cisco Secure Access Control Server Release 4.0 for Windows, hereafter referred to as ACS.
Introduction to ACS
ACS is a scalable, high-performance Remote Access Dial-In User Service (RADIUS) and Terminal Access Controller Access Control System (TACACS+) security server.
ACS Features, Functions and Concepts
ACS incorporates many technologies to render AAA services to network-access devices, and provides a central access-control function.
Managing and Administrating ACS
ACS provides a flexible administration scheme to configure, maintain, and protect its AAA functionality. You can perform nearly all ACS administration tasks through the ACS web interface. You use the web interface to easily modify the ACS configuration from any connection on your LAN or WAN, and view it by using a web browser.
ACS Specifications
Note For the hardware, operating system, third-party software, and network requirements, see the Installation Guide for Cisco Secure ACS for Windows at: http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/acs40/install/index.htm.
What is the log target for ACS?
By default, a Log Target called the LogCollector identifies the Monitoring and Reports server.
What is ACS 5.8?
This chapter describes logging functionality in ACS 5.8. Administrators and users use the various management interfaces of ACS to perform different tasks. Using the administrative access control feature, you can assign permissions to administrators and users to perform different tasks.
What interfaces can you use to log messages?
You can use the following ACS interfaces for logging: Web interface—This is the primary logging interface. You can configure which messages to log and to where you want the messages logged. Command line interface (CLI)—Allows you to display and download logs, debug logs, and debug backup logs to the local target.
How to send Cisco logs?
You can use the web interface and the CLI to send logs, including debug logs, to Cisco technical support personnel if you need troubleshooting assistance. In the web interface, choose Monitoring and Reports > Launch Monitoring and Report Viewer > Monitoring and Reports > Troubleshooting > ACS Support Bundle.
Where are administrative and operational audit messages logged?
For example, administrative and operational audit messages are always logged to the local store, but you can also configure them to be logged to a remote syslog server or the Monitoring and Reports server log target. However, administrative and operational audit messages configured to be additionally logged to a remote log target are only logged to that remote log target if they are first logged successfully to the local log target.
When you configure a critical log target, and a message is sent to that critical log target, the message is?
When you configure a critical log target, and a message is sent to that critical log target, the message is also sent to the configured noncritical log target on a best-effort basis.
Does ACS track actions?
Apart from this, you also need an option to track the various actions performed by the administrators and users. ACS offers you several logs that you can use to track these actions and events.
What is ACS in Cisco?
The Cisco Secure Access Control Server Release 4.1 , hereafter referred to as ACS, authenticates users against one of several possible databases, including its internal database. You can configure ACS to authenticate users with more than one type of database. With this flexibility you can use user account data that is collected in different locations without having to explicitly import the users from each external user database into the ACS internal database. You can also apply different databases to different types of users, depending on the security requirements that are associated with user authorizations on your network. For example, a common configuration is to use a Windows user database for standard network users and a token server for network administrators. For information about authentication protocols and the external database types that support them, see Authentication Protocol-Database Compatibility, page 1-8 .
How does ACS work?
ACS forwards the username and password to an LDAP database by using a Transmission Control Protocol (TCP) connection on a port that you specify. The LDAP database passes or fails the authentication request from ACS. When receiving the response from the LDAP database, ACS instructs the requesting AAA client to grant or deny the user access, depending on the response from the LDAP server.
What is ACS in Windows XP?
ACS supports the authentication of computers that are running the Microsoft Windows operating systems that support EAP computer authentication, such as Windows XP with Service Pack 1. Machine authentication, also called computer authentication, allows networks services only for computers known to Active Directory.
What is ACS database?
The ACS internal database is crucial for the authorization process. Regardless of whether a user is authenticated by the internal user database or by an external user database, ACS authorizes network services for users based on group membership and specific user settings in the ACS internal database.
What is CSNTExtractUserClearTextPw?
The following example routine creates in Microsoft SQL Server a procedure named CSNTExtractUserClearTextPw, the default procedure that ACS uses for CHAP/MS-CHAP/ARAP authentication. Table and column names that could vary for your database schema appear in variable text. For more information about data type definitions, procedure parameters, and procedure results, see ODBC Database (ACS for Windows Only) .
When you configure ACS to authenticate users against an ODBC-compliant relational database, must you create?
When you configure ACS to authenticate users against an ODBC-compliant relational database, you must create a stored procedure to perform the necessary query and return the values that ACS expects. The values that are returned and the tasks that are required of the stored procedure vary depending on the authentication protocol used.
Can ACS be used in relational database?
As with Windows user database support, you can use ACS ODBC-compliant relational database support to use existing user records in an external ODBC-compliant relational database. Configuring ACS to authenticate against an ODBC-compliant relational database does not affect the configuration of the relational database. To manage your relational database, refer to your relational database documentation.
How to enable or disable ACS configuration web?
To enable or disable an interface for ACS configuration web, use the acs config-web-interface command in the EXEC mode.
How to back up ACS configuration?
To back up an ACS configuration (not including the ADE OS data), use the acs backup command in the EXEC mode.
How to enter ACS configuration mode?
To enter the ACS Configuration mode, use the acs-config command in the EXEC mode.
How to start or stop an ACS instance?
To start or stop an individual process of an ACS instance, use the acs command in the EXEC mode.
How to delete acs log?
To delete an ACS run-time core file or JVM core log excluding the latest one, use the acs delete log command in the EXEC mode.
What is the default username for ACS?
After resetting your password and installing a valid license, use the default username ( acsadmin) and changed password, or the username and password for a newly created admin user, to access the ACS CLI in the ACS Configuration mode.
How many users can access ACS?
Up to six users can access the ACS Configuration mode at a time; six users equal six sessions. When one of the six sessions ends, you must wait up to five minutes for the session to be available to another user.
What is ACS report?
These reports show the status of user accounts when you access them in the ACS web interface. They are available only in the web interface, are always enabled, and require no configuration.
What does "logged in users" mean in ACS?
From a Logged-in Users Report, you can instruct ACS to delete users who are logged into a specific AAA client. When a user session terminates without a AAA client sending an accounting stop packet to ACS, the Logged-in Users Report continues to show the user. Deleting logged-in users from a AAA client ends the accounting for those user sessions.
What is a DSN in ACS?
The System DSN to be used by ACS for communicating with the relational database is created on the computer running ACS. The name you assigned to the DSN appears in the Data Source list on each ODBC log configuration page.
What is the name of the CSV file in ACS?
The current file is named log .csv, where log is the name of the log.
What is system log?
System logs are logs about the ACS system and therefore record system-related events. These logs are useful for troubleshooting or audits. They are always enabled and are only available in CSV format. Some system logs can be configured. For information about each system log, including which system logs are configurable, see Table 11-4 .
What is ACS watchdog packet?
If you want, you can configure ACS to record update packets, too. In addition to providing interim accounting information during a user session, update packets drive password-expiry messages via ACS Authentication Agent. In this use, the update packets are called watchdog packets.
How many types of logs are there in ACS?
ACS provides logs that can be divided into four types:
