Advanced Identity Agents Configuration

In This Section: Customizing Parameters Advanced Identity Agent Options

Customizing Parameters

You can change settings for Identity Agent parameters to control Identity Agent behavior. You can change some of the settings in SmartConsole and others using the Identity Agent Configuration tool.

To change Identity Agents parameters in SmartConsole:

1. In SmartConsole, go to Menu > Global properties.

   The Global Properties window opens.

2. In the left navigation tree, click Advanced > Configure.
3. Go to Identity Awareness > Agent.
4. Change the Identity Agents parameters.
5. Click OK.

This is a sample list of parameters that you can change:

Parameter	Description
nac_agent_disable_settings	Whether users can right click the Identity Agent client (umbrella icon on their desktops) and change settings.
nac_agent_email_for_sending_logs	You can add a default email address, to which to send client troubleshooting information.
nac_agent_disable_quit	Whether users can right click the Identity Agent client (umbrella icon on their desktops) and close the agent.
nac_agent_disable_tagging	Whether to disable the packet tagging feature that prevents IP Spoofing.
nac_agent_hide_client	Whether to hide the client (the umbrella icon does not show on users' desktops).

Kerberos SSO Compliance

The Identity Awareness Single Sign-On (SSO) solution for Identity Agents gives the ability to authenticate users transparently that are logged in to the domain. This means that a user authenticates to the domain one time and has access to all authorized network resources without additional authentication.

Using Identity Agents gives you:

• User and computer identity
• Minimal user intervention - The administrators do all the necessary configuration steps and no user input is required user.
• Seamless connectivity - Transparent authentication when users are logged in to the domain. If you do not want to use SSO, users enter their credentials manually. You can let them save these credentials.
• Connectivity through roaming - Users stay automatically identified when they move between networks, while the client detects the movement and reconnects.
• Added security - You can use the patented packet tagging technology to prevent IP Spoofing. Identity Agents also gives you strong (Kerberos based) user and computer authentication.

You get SSO in Windows domains with the Kerberos authentication protocol. Kerberos is the default authentication protocol used in Windows 2000 and above.

The Kerberos protocol is based on the idea of tickets, encrypted data packets issued by a trusted authority, which in this case, is the Active Directory (AD). When a user logs in, the user authenticates to a domain controller that provides an initial ticket granting ticket (TGT). This ticket vouches for the user’s identity. When the user needs to authenticate against the Identity Awareness Gateway, the Identity Agent presents this ticket to the domain controller and requests a service ticket (SR) for a specific resource (Security Gateway that Identity Agents connect to). The Identity Agent then presents this service ticket to the Security Gateway that grants access.

How SSO Works

This is the workflow for SSO (Single Sign On):

1. The user logs in to the computer and authenticates to the AD server.
2. The AD sends an initial ticket (TGT) to the computer.
3. The Identity Agent connects to the Security Gateway, which then requests the identity.
4. The Identity Agent requests an SR (service ticket) for the Security Gateway and presents the TGT to the AD server.
5. The AD server sends the SR to the computer.

   The user name is encrypted with the shared secret between the Security Gateway and the AD server.

6. The Identity Agent sends the SR to the Security Gateway.
7. The Security Gateway uses the shared secret to decrypt the ticket and confirms the user identity.
8. The user can access the Data Center.

SSO Configuration

SSO configuration includes two steps:

• AD Configuration - Creating a user account and mapping it to a Kerberos principal name.
• SmartConsole Configuration - Creating an LDAP Account Unit and configuring it with SSO.

AD Configuration

To use Kerberos with AD, make a Kerberos principal name with the Check Point Security Gateway service. Map this new account to the domain name.

Use the setspn.exe utility. Make sure you have the correct version.

Important - If you used the setspn utility before, with the same principal name, but with a different account, you must delete the different account, or remove the association to the principal name.
To remove the association, run:
setspn -D ckp_pdp/<domain_full_dns_name> <old_account name>

If you do not do this, authentication will fail.

To configure AD for Kerberos:

1. Make a new user account.
2. Open the command line (Start > Run > cmd).
3. Run:
   setspn -A ckp_pdp/<domain_full_dns_name> <username>

To see users associated with the principle name, run: setspn -Q ckp_pdp*/*

When done, configure an Account Unit in the SmartConsole, to use this account.
