1 Dell SonicWALL Capture Advanced Threat Protection Beta Feature Guide June 2016 Topics: Purpose Supported platforms Overview Licensing Capture ATP Configuring Capture ATP About Dell Purpose This feature guide describes how to install and configure Dell SonicWALL Capture Advanced Threat Protection (ATP). Capture ATP is a new security service offering for Dell SonicWALL firewalls. Supported platforms Dell SonicWALL Capture ATP is supported on the following Dell SonicWALL network security appliances running SonicOS and higher: SuperMassive 9600 NSA 6600 TZ600 SuperMassive 9400 NSA 5600 TZ500 and TZ500 Wireless SuperMassive 9200 NSA 4600 TZ400 and TZ400 Wireless NSA 3600 NSA 2600 TZ300 and TZ300 Wireless SOHO Wireless Dell SonicWALL Capture Advanced Threat Protection 1

2 Overview Capture Advanced Threat Protection (ATP) is sold as an add-on security service to the firewall, similar to Gateway Anti-Virus (GAV). Capture ATP helps a firewall identify whether a file is malicious or not by transmitting the file to the Cloud where the Capture ATP service analyzes the file. Capture ATP then sends the results to the firewall. This process is done in real time while the file is being processed by the firewall. The firewall is located at the customer premises, but the Capture ATP server and database are located at a Dell SonicWALL facility. The firewall creates a secure connection with the Capture ATP cloud service before transmitting data. Before you can enable Capture ATP you must first get a license, and you must enable the Gateway Anti-Virus (GAV) service. You can choose the settings for GAV, such as protocols to scan for files, or IPs to exclude from scanning, and they will also apply to the Capture ATP service. All files that are submitted to Capture ATP for sandbox analysis are first subjected to pre-filtering. Files can be rejected or passed based on pre-filtering. If pre-filtering determines a file to be malicious or benign, the file will not be analyzed by the Capture ATP sandboxes. If a file is not determined to be malicious or benign by the GAV service during the Capture pre-filtering process, the file is submitted to the Capture ATP sandboxes for analysis. If the file does not appear in the Capture ATP > Scanning History page, that means that the file was not analyzed in the sandboxes, but was passed or rejected based on the Capture pre-filtering process. Only files that have been analyzed by the Capture ATP sandboxes are listed on the Scanning History page. Files that are determined to be malicious are kept for 30 days and are then deleted. Other files are deleted after the analysis is complete. The Block Until Verdict option ensures that no packets get through until the file is completely analyzed and it is determined to be either malicious or benign. The file is held until the last packet is analyzed. If the file has malware, the last packet is dropped, and the file is blocked permanently. Once a file is blocked permanently, there is no way to recover it or analyze it again. Capture ATP provides a file analysis report (scanning report) with detailed threat behavior information. If the Block Until Verdict option is not enabled, the scanning report provides information necessary to respond to a threat or infection. When a file is determined to be malicious, threat intelligence is incorporated into the other Dell security services, such as GAV and Cloud Anti-Virus, so that other firewalls will benefit within 48 hours. All files are sent to the Capture ATP cloud over an encrypted connection. Dell does not keep the files. All file types, whether they are malicious or benign are removed from the Capture ATP server after they are analyzed, except for executable files that contain malware. Executable files that are determined to be malicious are sent to the Dell threat research facility for further analysis, but they are also removed after a certain time period.

3 Licensing Capture ATP This section describes how to license the Capture ATP feature on your Dell SonicWALL appliances. The Capture ATP license requires that the Gateway-Antivirus (GAV) service is also licensed. You must enable Gateway-Antivirus (GAV) and Cloud Anti-Virus before you can enable Capture ATP. Currently, only Beta licenses are available for Capture ATP.

4 Activating a Beta Capture ATP license This procedure describes how to activate a Beta Capture ATP license. To activate a Beta Capture ATP license on your firewall: 1 Submit the serial number of the appliances you would like to activate by completing the survey at 2 After you complete the survey, you will be notified by when the Capture ATP license has been activated for your appliance. When Capture ATP is not licensed, the left-hand navigation panel only shows the Settings page. The other Capture ATP pages are not shown in the panel until Capture ATP is licensed and enabled.

5 When Capture ATP is not licensed, the Capture ATP > Settings page will display the page with the following message and instructions to go to the System > Licenses page where you can view licenses and get licenses. Dell SonicWALL Capture Advanced Threat Protection 5

6 Enabling SonicOS services Before you can enable Capture ATP, the SonicOS services Gateway Anti-Virus and Cloud Anti-Virus Database must be enabled. To enable the SonicOS services Gateway Anti-Virus and Cloud Anti-Virus Database: 1 On the firewall, go to the Security Services > Gateway Anti-Virus page. 2 Ensure that the checkboxes for Enable Gateway Anti-Virus and Enable Cloud Anti-Virus Database are checked. You can also choose the protocols that are used to scan for malicious files. The GAV protocol settings will apply to both GAV and Capture ATP services. You can also use GAV settings to select or define address objects to exclude from GAV and Capture ATP scanning. If a file is determined not to be malicious or benign by GAV during the pre-filtering process, the file is submitted to Capture ATP for analysis, and if Capture ATP determines that the file is malicious, it creates a detailed analysis report that can be accessed from the Capture ATP > Scanning History page.

8 Capture ATP will stop working if either Gateway Anti-Virus or Cloud Anti-Virus is disabled. If Gateway Anti-Virus is not enabled, the Capture ATP > Settings page will show the following message with instructions to go to the Security Services > Gateway Anti-Virus page where you can enable it. You can view the Gateway Anti-Virus Scan Settings by hovering on the small arrow in line with Enable Capture Advanced Threat Protection. Disabling Gateway Anti-Virus You can disable the Gateway Anti-Virus (GAV) service by clearing the checkbox for it on the Security Services > Gateway Anti-Virus page. If you disable Gateway Anti-Virus while Capture ATP is enabled, a popup message is displayed warning you that Capture ATP will also be disabled. Dell SonicWALL Capture Advanced Threat Protection 8

9 Configuring Capture ATP Topics Settings Dashboard Scanning History Submit Files Settings When Capture ATP is licensed, the Settings page shows the expiration date in the Capture ATP Status panel, and below that a checkbox to Enable Capture Advanced Threat Protection. To enable Capture ATP: 1 On the firewall, go to the Capture ATP > Settings page. 2 Select the checkbox for Enable Capture Advanced Threat Protection. 3 (Optional) If you want files that are being analyzed to be blocked until the analysis is finished, select the checkbox for Block Until Verdict. The file will be blocked until the Capture ATP analysis is finished, and the user will see a message stating that the file is blocked until the analysis is complete. When the Capture ATP analysis is finished, the file will either be passed or will be blocked permanently. If the file is malicious, it is blocked permanently, and there is no way to recover that file. If it is benign, the file is released and passed through.
