Adding Users to the Rule Base

Using Identity Awareness

The Identity Awareness Software Blade lets you configure the Firewall to enforce access control for individual users and groups. You can use Identity Sources to get information about users and groups to create flexibility and additional security for the Rule Base. Identity Awareness lets you create rules that are for the specified users for these Rule Bases:

  • Firewall
  • URL Filtering and Application Control
  • DLP
  • Anti-Bot

For more about using Identity Awareness, see the R77 Identity Awareness Administration Guide.

Identity Sources

After the Security Gateway acquires the identity of a user, user-based rules can be enforced on the network traffic. Identity Awareness can use these sources to identify users:

  • AD Query - Seamlessly queries the AD (Active Directory) servers to get user information.
  • Browser-Based Authentication - Uses a Captive Portal to authenticate users.
  • Identity Agent - Client that is installed on endpoint computers connects to a Security Gateway and authenticates users.
  • Terminal Servers Identity Agent - An agent on a Terminal or Citrix server connects to a Security Gateway to get user information.
  • Remote Access Devices - Use Identity Awareness with the Mobile Access and VPN Software Blades (Office Mode only) to authenticate users that connect from a remote device.

AD Query

The Security Gateway registers to receive security event logs from the AD domain controllers when the security policy is installed. When a user authenticates with AD credentials, these event logs are generated and are sent to the Security Gateway. The Firewall identifies the user based on the AD security event log. The user sends traffic that matches an Identity Awareness rule in the security policy. The Firewall can enforce the user-based rule on the traffic.

Browser-Based Authentication

Browser-Based Authentication uses the Internet browser to identify users. You can use these Browser-Based Authentication solutions:

  • Captive Portal
  • Transparent Kerberos Authentication

Captive Portal uses a web interface to authenticate users before they can access network resources. When users try to access a protected resource, they must log in to a web page to continue.

When Transparent Kerberos Authentication is enabled, the Transparent Authentication page tries to authenticate users before the Captive Portal web page opens. The Transparent Authentication page communicates with the AD to use the Kerberos protocol to authenticate the users. If the users are successfully authenticated, then they can access the network resources. If they are not authenticated, then they are redirected to the Captive Portal.

Enabling Identity Awareness

There is an Identity Awareness configuration wizard in SmartDashboard that helps you enable and configure the Identity Awareness Software Blade. You can use the configuration wizard on these identity sources:

  • AD Query
  • Browser-Based Authentication
  • Terminal Servers

Using the Identity Awareness Wizard

The Identity Awareness Configuration wizard configures how the Security Gateway gets information about users and computers.

This section gives an example of how to configure the AD query and browser-based methods for Identity Awareness.

To use the configuration wizard:

  1. From the Network Objects tree, double-click the Security Gateway.

    The Gateway Properties window opens.

  2. From the navigation tree, click General Properties.
  3. From the Network Security tab, select Identity Awareness.

    The Identity Awareness Configuration wizard opens.

  4. Select AD Query and Browser-Based Authentication and then click Next.

    The Integration With Active Directory window opens.

  5. Select the AD domain and enter the Username and Password.

    Make sure that the AD account has domain administrator privileges.

  6. Click Connect.

    The Successfully connected message is shown.

  7. Click Next.

    The Browser-Based Authentication Settings window opens.

  8. Enter the URL for the Captive Portal and then click Next.

    The Identity Awareness is Now Active window opens.

  9. Click Finish and then install the policy.

Identity Awareness and Remote Access

Identity Awareness for Mobile Access and IPsec VPN clients works in Office Mode for Security Gateways. The Remote Access option is included as an identity source when you enable Identity Awareness.

To enable or disable Remote Access for Identity Awareness:

  1. From the Network Objects tree, double-click the Security Gateway.

    The Gateway Properties window opens.

  2. From the navigation tree, click Identity Awareness.
  3. Select or clear Remote Access.
  4. Click OK and then install the policy.

Creating a New AD Object

The Identity Awareness configuration wizard helps you create a new AD (Active Directory) LDAP Account Unit object in SmartDashboard. Enter the AD settings in the Integration with Active Directory window.

To create new AD Account Unit with the Identity Awareness wizard:

  1. From the Integration with Active Directory window, select Create new domain.

    Integration_AD_Window

  2. Enter the settings for the AD domain controller.
  3. Click Connect.

    SmartDashboard connects to the AD server.

  4. Click Next and then follow the instructions and finish the wizard.

    SmartDashboard creates the new AD Account Unit.

Working with Access Roles

After you enable Identity Awareness, you create Access Role objects.

You can use Access Role objects as source and/or destination parameter in a rule. Access role objects can include one or more of these objects:

  • Users and user groups
  • Computers and computer groups
  • Networks

To create an Access Role object:

  1. Select Users and Administrators in the Objects Tree.
  2. Right-click Access Roles > New Access Role.

    The Access Role window opens.

  3. Enter a Name and Comment (optional) for the access role.
  4. In the Networks tab, select one of these:
    • Any network
    • Specific networks - Click the plus sign and select a network.

      Your selection is shown in the Networks node in the Role Preview pane.

  5. In the Users tab, select one of these:
    • Any user
    • All identified users - Includes users identified by a supported authentication method (internal users, AD users or LDAP users).
    • Specific users - Click the plus sign.

      A window opens. You can search for Active Directory entries or select them from the list.

  6. In the Machines tab, select one of these:
    • Any machine
    • All identified machines - Includes computers identified by a supported authentication method (AD).
    • Specific machines - Click the plus sign.

      You can search for AD entries or select them from the list.

  7. Optional: For computers that use Full Identity Agents, from the Machines tab select Enforce IP Spoofing protection.
  8. Click OK.

    The access role is added to the Users and Administrators tree.

Using Identity Awareness in the Firewall Rule Base

The Identity Awareness Software Blade lets you customize the Firewall for users regardless of what computer they are using. Use Access Role objects in a rule and Identity Awareness identifies users that match the rule. You can also enable an Accept action to redirect traffic from an unidentified user to a Captive Portal.

Sample Firewall Workflow with Identity Awareness

The Firewall inspects traffic that starts from a source that matches the Access Role object. The Identity Awareness source tries to identify the user.

  • If the user is identified, the traffic is allowed.
  • If the user is not identified, the traffic is only allowed when the user authenticates to the Captive Portal. If Captive Portal is not enabled, or the user does not authenticate, then the traffic is dropped.

Redirecting to a Captive Portal

You can configure rules that use an Access Role object and an Accept action, to redirect HTTP traffic to a Captive Portal. The rule allows traffic when the users for the Access Role are identified. If the Captive Portal action is enabled, these are the procedures for the Firewall to identify a user:

  • The Identity Awareness source identifies the user
  • The user authenticates at the Captive Portal

Rules can redirect HTTP traffic according to these parameters:

  • Source - Includes an Access Role object
  • Action - Uses Accept

To enable Captive Portal for a rule:

  1. Right-click the Action cell and select Edit Properties.

    The Action Properties window opens.

  2. Select the Redirect http connections to an authentication (captive) portal.
  3. Click OK.

    The Action column shows accept (display captive portal).

  4. Install the policy.

Using User Directory

User Directory lets you integrate LDAP and other external user management servers with Check Point products and security solutions. These are some of the Software Blades that work with User Directory:

  • Mobile Access
  • Identity Awareness
  • Data Loss Prevention

User Directory Features

  • Use LDAP servers to manage user information for the network
  • Security Gateways can retrieve CRLs (Certificate Revocation Lists)
  • Security Management Server can use LDAP information to authenticate users
  • High Availability can duplicate and backup user information across multiple LDAP servers
  • Create multiple Account Units to work with distributed databases
  • Use profiles to support multiple LDAP vendors
  • Encrypt User Directory connections

Deploying User Directory

User Directory integrates the Security Management Server and an LDAP server and lets the Security Gateways use the LDAP information.

Item

Description

1

Security Gateway - Retrieves LDAP user information and CRLs

2

Security Gateway - Queries LDAP user information, retrieves CRLs, and does bind operations for authentication

3

Security Management Server - Uses User Directory to manage user information

4

LDAP server - Server that holds one or more Account Units

Creating an Account Unit

An Account Unit represents branches of user information on one or more LDAP servers. The Account Unit is the interface between the LDAP servers and the Security Management Server and Security Gateways.

When you enable the Identity Awareness and Mobile Access Software Blades, SmartDashboard opens a configuration wizard. The Active Directory Integration window of this wizard can create a new AD Account Unit. After you complete the wizard, SmartDashboard creates the AD object and Account Unit.
