Threat Prevention and UserCheck

UserCheck handles specified threat incidents. UserCheck notifications inform the user of data capture. If the action is Ask, the user must provide a reason to allow the traffic. User decisions are logged. You can develop an effective prevention policy based on logged user responses.

For each Threat Prevention profile, you can define the action that is taken when a malicious file or activity is identified.

Action	Description
Ask	The Software Blade blocks the file or traffic until the user makes sure that the gateway should send it. The user decides if the file or traffic are allowed or not. The decision itself is logged in the User Response field in the Ask User log.
Prevent	The Software Blade blocks the file or traffic. You can show a UserCheck Prevent message to the user.
Detect	The Software Blade allows the file or traffic. The event is logged and is available for your review and analysis in the Logs & Monitor view.

For more about using UserCheck objects and settings, see the UserCheck chapters in the R80.30 Data Loss Prevention Administration Guide.

Using the Threat Prevention UserCheck Pane

On the UserCheck page, you can create, edit, and preview UserCheck interaction objects and their messages. It has these options:

Option	Meaning
New	Creates a new UserCheck object

• Email - How the message shows in an email
• Agent -How the message shows in the UserCheck agent

Configuring the Security Gateway for UserCheck

Enable or disable UserCheck directly on the Security Gateway. Make sure that the UserCheck is enabled on each Security Gateway in the network. To enable UserCheck , enable a blade that has the UserCheck functionality.

The Security Gateway has an internal persistence mechanism that preserves UserCheck notification data if the Security Gateway or cluster reboots. Records of a user answering or receiving notifications are never lost.

To configure UserCheck on a Security Gateway:

1. In SmartConsole, click Gateways & Servers and double-click the Security Gateway.

   The Gateway Properties window opens.

2. From the navigation tree, click UserCheck.

   The UserCheck page opens.

3. Make sure Enable UserCheck for active blades is selected
4. In the UserCheck Web Portal section:

   In the Main URL field, enter the primary URL for the web portal that shows the UserCheck notifications.

   If users connect to the Security Gateway remotely, make sure that the Security Gateway internal interface (in the Network Management page) is the same as the Main URL.

   Note - The Main URL field must be manually updated if:

   • The Main URL field contains an IP address and not a DNS name.
   • You change a gateway IPv4 address to IPv6 or vice versa.
5. Optional: Click Aliases to add URL aliases that redirect different hostnames to the Main URL.

   The aliases must be resolved to the portal IP address on the corporate DNS server

6. In the Certificate section, click Import to import a certificate that the portal uses to authenticate to the Security Management Server.

   By default, the portal uses a certificate from the Check Point Internal Certificate Authority (ICA). This might generate warnings if the user browser does not recognize Check Point as a trusted Certificate Authority. To prevent these warnings, import your own certificate from a recognized external authority.

   Note - After you download your certificate, you can click Replace to replace it with a different certificate, and click View to see the certificate information.

7. In the Accessibility section, click Edit to configure interfaces on the Security Gateway through which the portal can be accessed. These options are based on the topology configured for the Security Gateway. The topology must be configured.

   Users are sent to the UserCheck portal if they connect:

   • Through all interfaces
   • Through internal interfaces (default)
     • Including undefined internal interfaces
     • Including DMZ internal interfaces
     • Including VPN encrypted interfaces (default)

     Note: Make sure to add a rule to the Firewall Rule Base that allows the encrypted traffic.

   • According to the Firewall Policy. Select this option if there is a rule that states who can access the portal.

   If the Main URL is set to an external interface, you must set the Accessibility option to one of these:

   • Through all interfaces - necessary in VSX environment
   • According to the Firewall Policy
8. In the Mail Server section, configure a mail server for UserCheck. This server sends notifications to users that the Gateway cannot notify using other means, if the server knows the email address of the user. For example, if a user sends an email which matched on a rule, the Gateway cannot redirect the user to the UserCheck portal because the traffic is not http. If the user does not have a UserCheck client, UserCheck sends an email notification to the user.
   • Use the default settings - Click the link to see which mail server is configured.
   • Use specific settings for this gateway - Select this option to override the default mail server settings.
   • Send emails using this mail server - Select a mail server from the list, or click New and define a new mail server.
9. Click OK.
10. If there is encrypted traffic through an internal interface, add a new rule to the Firewall Layer of the Access Control Policy. This is a sample rule:

    Source	Destination	VPN	Services & Applications	Action
    Any	Security Gateway on which UserCheck client is enabled	Any	UserCheck	Accept

11. Install the Access Control Policy.
