About Administrator Accounts

From the Administration Control page, you can link to pages that establish the names, passwords, and privileges for individual administrators or groups of administrators.

ACS administrator accounts are:

Unique to ACS and not related to other accounts, such as Windows administrator accounts, ACS TACACS+ accounts, or any other ACS user accounts.

Unrelated to external ACS users because ACS stores ACS administrator accounts in a separate internal database.

Privileges

The privileges that you grant to each administrator determine access to areas of the web interface. By default, new administrators do not have any privileges.

Administration Control Privilege

Administrators who have the Administration Control privilege can access the complete Administration Control page. For these administrators, this page provides management of administrators and access to pages that control administrative access policy. Restricted administrators can update their passwords. Figure 11-1 shows the access granted by the administration control privilege.

Figure 11-1 The Administration Control Privilege

Examples of privileges that you can grant to administrators or groups of administrators include:

Shared profile components

Network, system, and interface configuration

Administration control

External user databases, posture validation, and network access profiles (NAPs)

Reports and activities

For example, you are an administrator with the Administration Control privilege who wants to configure access to the Network Configuration section of the web interface for administrators whose responsibilities include network management. Therefore, you check only the Network Configuration privilege for the applicable administrator accounts.

However, you might want to configure all privileges for an administrator or an administrative group. In this case, you click the Grant All (privileges) option.

The web interface also includes a filter that can control the type of access granted to administrators. For example, you can configure an administrator for read-only access to groups of users, or you can grant them add and edit access to the same groups.


Note See Chapter 10 "Logs and Reports," for information on generating reports of privileges granted to administrators.


The Influence of Policy

The Administration Control page also includes links to access, session, and password policy configuration pages. These policies influence all account logins and include the following configuration options:

Access Policy—IP address limitations, HTTP port restrictions, and secure socket layer (SSL) setup.

Session Policy—Timeouts, automatic local logins, and response to invalid IP address connections.

Password Policy—Password validation, lifetime, inactivity, and incorrect attempts.

Group Access Privileges

ACS includes options that determine the type of administrator access to groups or users in groups. When enabled, these options grant an administrator the following privileges with respect to any available group:

Add or edit user pages

Edit group pages

Read access to user pages

Read access to the group pages

Table 11-1 describes the interaction of the options:

Table 11-1 Group Access Options

Password Expirations and Account Lockouts

Successful logins take administrators to the main ACS web interface page. However, all logins are subject to the restrictions that have been configured in Administration Control, including expiration, account lockout, and password configuration options.

Limits set for password lifetime and password inactivity can force password change or account lockout. In addition, the limit set for failed attempts can force password change, and privileged administrators can manually lock accounts. In the case of an account lockout, a privileged administrator must unlock the account.

ACS includes the Account Never Expires option that can globally override automatic account lockouts and password configuration options. If the Account Never Expires option is enabled for a specific administrator, all administrator lockout options are ignored.

In the case of an account lockout, ACS displays the Login Process Fail page. Depending on the options, ACS displays the following pages for changing passwords:

A password update page appears when you attempt to log in.

The Change Password page appears when you click the Administration Control button in the navigation bar, if you do not have the Administration Control privilege. The Change Password page includes a list of the password criteria.

Figure 11-2 shows the process flow at login time.

Figure 11-2 Login Process Flow

1 When the administrator reaches the Incorrect Password Attempts limit, ACS locks the account. At this point, successful attempts will fail. However, if Account Never Expires is set, then the account cannot be locked out.

2 The administrator has successfully logged in. Therefore, if only the password has been incorrectly used, ACS allows retries even though the administrator has exceeded the Incorrect Password Attempt limit.

Support for Regulatory Compliance

ACS includes options that can support regulatory compliance. For example, an administrator with the Administration Control privilege can decide whether to grant the Administration Control privilege to other administrators. Administrators who do not have this privilege cannot access the administrator configuration details.

All administrator logins are subject to the policy that you configure for passwords and accounts, unless you check the Account Never Expires option. For example, ACS provides configurable limits on password lifetime, activity, and incorrect password attempts. These options can force password change and can result in automatic account lockout. Privileged administrators can also lock out an account. In addition, you can monitor the last password change and last account activity for each administrator.

In addition, you can restrict access to reports. For example, you can enable or disable an administrator's ability to change the Administration Audit report configuration.

You can also configure administrator access to user groups. You can selectively choose to allow administrators to setup groups and add or edit users. ACS also provides configuration of administrator read access to users and groups.

Logging In

The ACS login page is the access point for the web interface. If your valid password expires, or if a change in policy affects a password, ACS forces you to change your password when you log in. If you are locked out, contact an administrator who has the Administration Control privilege.


Note Administrators must have a Windows domain administrator account in order to log in and manage ACS services. However, Windows domain administrators cannot log in to ACS. Only administrators with valid ACS accounts can log in to ACS. For information, see the Installation Guide for Cisco Secure ACS for Windows Release 4.2 or the Installation Guide for Cisco Secure ACS Solution Engine Release 4.2.


ACS for Windows

To log in from a client, you must have an administrator account. However, the Session Policy includes an Allow automatic local login option. If this option is enabled, you can bypass the login page on the server that is running ACS. This option is available for unintentional lockouts. For more information about automatic local logins, see Configuring Session Policy.

ACS SE

To access the ACS web interface from a browser, log in to ACS by using an administrator account.

The first administrator to log in must create an administrator name and password by using the Add ACS Admin command in the command line interface (CLI) to create the administrator name and password for the first account. For complete information on the CLI, see the "Administering Cisco Secure ACS Solution Engine" chapter of the Installation Guide for Cisco Secure ACS Solution Engine Release 4.2.

In cases where ACS has locked out all administrators, use the Unlock <administrator name> command from the CLI. Only an administrator with the Administration Control privilege can use this command. For complete information on the CLI, see the "Administering Cisco Secure ACS Solution Engine" chapter of the Installation Guide for Cisco Secure ACS Solution Engine Release 4.2.

To log in:


Step 1 To start ACS, click the ACS Admin button in the Cisco Secure ACS program group.

Option
Description
Administrator Details

Administrator Name (appears only on the Add Administrator page)

The login name for the ACS administrator account. Administrator names can contain 1 to 32 characters, excluding the left angle bracket (<), the right angle bracket (>), and the backslash (\). An ACS administrator name does not have to match a network user name.

The administrator name does not appear on the Edit Administrator page because ACS does not allow name changes for previously configured administrators. To change names, delete the account and configure an account with a new name. To disable an account, revoke all privileges.

Password

The password can match the password that the administrator uses for dial-in authentication, or it can be a different password. ACS enforces the options in the Password Validation Options section on the Administrator Password Policy page.

Passwords must be at least four characters long and contain at least one numeric character. The password cannot include the username or the reverse username, must not match any of the previous four passwords. and must be in ASCII characters. For errors in passwords, ACS displays the password criteria.

If the password policy changes and the password does not change, the administrator remains logged in. ACS enforces the new password policy at the next login.

Confirm Password

Verifies the password in the Password field. For errors in password typing, ACS displays an error message.

Last Password Change (Edit Administrator page only)

Displays the date of the change on which a password changes through administrative action on this page or through expiration of a password during login. (Read-only) Always displays the change date, not the expiration date. Does not appear until a new account has been submitted.

Last Activity (Edit Administrator page only)

Displays the date of the last successful login. (Read-only) Does not appear until a new account has been submitted.

Account Never Expires

Prevents account lockout by overriding the lockout options on the Administrator Password Policy page with the exception of manual lockout. Therefore, the account never expires but password change policy remains in effect. The default value is unchecked (disabled).

Account Locked

Prevents an administrator, who was locked out due to the lockout options on the Password Policy page, from logging in. When unchecked (disabled), this option unlocks an administrator who was locked out.

Administrators who have the Administration Control privilege can use this option to manually lock out an account or reset locked accounts. The system displays a message that explains the reason for a lockout.

When an administrator unlocks an account, ACS resets the Last Password Change and the Last Activity fields to the day on which the administrator unlocks the account.

The reset of a locked account does not affect the configuration of the lockout and unlock mechanisms for failed attempts.

Administrator Privileges

Contains the privilege options for the User Setup and Group Setup sections of the web interface.

By default, a remote administrator does not have privileges.

Grant All

Enables all privileges. ACS moves all user groups to the Editable Groups list. A privileged administrator can also grant privileges to each ACS administrator by assigning privileges on an individual basis. In either case, the administrator can individually override options enabled by Grant All.

By default, ACS restricts all privileges for new administrator accounts.

Revoke All

Clears (restricts) all privileges. ACS removes all user groups from the Editable Groups list. Revoking all privileges for an existing account effectively disables the account. The administrator can individually override options disabled by Revoke All.

You can also disable an account by revoking all privileges.

User & Group Setup

Add/Edit users in these groups

Enables an administrator to add or edit users, and to assign users to the groups in the Editable groups list.

When enabled, this setting overrides the settings in the Read access to users in these groups option.

Setup of these groups

Enables an administrator to edit the settings for the groups in the Editable groups list.

When enabled, this setting overrides the settings in the Read access of these groups option.

Read access to users in these groups

Enables read-only access to users in the Editable groups.

When the Add/Edit users in these groups option is enabled, it overrides the settings in the Read access to users in these groups option.

If the Add/Edit users in these groups option is checked (enabled), it does not matter if this setting is enabled or disabled. The Add/Edit users in these groups setting overrides this setting, and the administrator can edit all users in the Editable groups.

If the Add/Edit users in these groups option is unchecked (disabled):

Check this check box to grant the administrator read access to the users in the Editable groups. In this case, the administrator cannot submit changes.

When unchecked, administrators cannot view users.

Read access of these groups

Enables read-only access to users in the Editable groups.

When the Add/Edit users in these groups option is enabled, it overrides the settings in the Read access to users in these groups option.

If the Add/Edit users in these groups option is checked (enabled), it does not matter if this setting is enabled or disabled. The Add/Edit users in these groups setting overrides this setting, and the administrator can edit the Editable groups.

If the Add/Edit users in these groups option is unchecked (disabled):

Check this check box to grant the administrator read access to the Editable groups list. In this case, the administrator cannot submit changes.

When unchecked, administrators cannot view groups.

Available groups

Lists all user groups. Administrators do not have access to the groups in this list.

Editable groups

Lists the user groups to which administrators have access. Other options in the User & Group Setup area determine the limits on administrator access to these groups and associated users in this list.

Reject connections from listed IP addresses

Restricts remote access to the web interface to IP addresses outside of the specified IP Address Ranges.

IP filtering operates on the IP address received in an HTTP request from a remote administrator's web browser. If the browser is configured to use an HTTP proxy server or the browser runs on a workstation behind a network device performing network address translation, IP filtering applies only to the IP address of the HTTP proxy server or the NAT device.

IP Address Ranges

The IP Address Ranges table contains ten rows for configuring IP address ranges. The ranges are always inclusive; that is, the range includes the Start and End IP addresses.

Use dotted-decimal format. The IP addresses that define a range must differ only in the last octet (Class C format).

Start IP Address

Defines the lowest included IP address in the specified range (up to 16 characters).

End IP Address

Defines the highest included IP address in the specified range (up to 16 characters).

HTTP Configuration
HTTP Port Allocation
 

Allow any TCP ports to be used for Administration HTTP Access

Enables ACS to use any valid TCP port for remote access to the web interface.

Restrict Administration Sessions to the following port range From Port n to Port n

Restricts the ports that ACS can use for remote access to the web interface. Use the boxes to specify the port range (up to five digits per box). The range is always inclusive; that is, the range includes the start and end port numbers. The size of the specified range determines the maximum number of concurrent administrative sessions.

ACS uses port 2002 to start all administrative sessions. Port 2002 does not need to be in the port range. Also, ACS does not allow definition of an HTTP port range that consists only of port 2002. The port range must consist of at least one port other than port 2002.

A firewall configured to permit HTTP traffic over the ACS administrative port range must also permit HTTP traffic through port 2002, because this is the port that a web browser must address to initiate an administrative session.

We do not recommend allowing administration of ACS from outside a firewall. If access to the web interface from outside a firewall is necessary, keep the HTTP port range as narrow as possible. A narrow range can help to prevent accidental discovery of an active administrative port by unauthorized users. An unauthorized user would have to impersonate, or "spoof," the IP address of a legitimate host to make use of the active administrative session HTTP port.

Secure Socket Layer Setup

Use HTTPS Transport for Administration Access

Enables ACS to use the secure socket layer (SSL) protocol to encrypt HTTP traffic between the CSAdmin service and the web browser that accesses the web interface. This option enables encryption of all HTTP traffic between the browser and ACS, as reflected by the URLs, that begin with HTTPS. Most browsers include an indicator for SSL-encrypted connections.

To enable SSL, first install an a server certificate and a certification authority certificate. Choose System Configuration > ACS Certificate Setup to access the installation process. With SSL enabled, ACS begins using HTTPS at the next administrator login. Current administrator sessions are unaffected. In the absence of a certificate, ACS displays an error.

Option
Description
Session Configuration

Session idle timeout (minutes)

Specifies the time, in minutes, that an administrative session must remain idle before ACS terminates the connection (four-digit maximum, 5 to 1439).

When an administrative session terminates, ACS displays a dialog box asking whether the administrator wants to continue. If the administrator chooses to continue, ACS starts a new administrative session.

This parameter only applies to the ACS administrative session in the browser. It does not apply to an administrative dial-up session.

Allow Automatic Local Login (ACS for Windows)

Enables administrators to start an administrative session without logging in, if they are using a browser on the computer that runs ACS. ACS uses a default administrator account named local_login to conduct these sessions.

When unchecked (disabled), administrators must log in using administrator names and passwords.

Note To prevent accidental lockout when there are no defined administrator accounts, ACS does not require an administrator name and password for local access to ACS.

The local_login administrator account requires the Administration Control privilege. ACS records administrative sessions that use the local_login account in the Administrative Audit report under the local_login administrator name.

Respond to invalid IP address connections

Enables ACS to send an error message in response to attempts to start a remote administrative session by using an IP address that is invalid according to the IP address Range settings in the Access Policy. If this check box is clear, ACS does not display an error message when an invalid remote connection attempt is made. (the default is Enabled)

Disabling this option can help to prevent unauthorized users from discovering ACS.
