Recipes for Sandbox inspection

AntiVirus

The following recipes provide information about Sandbox inspection with AntiVirus:

Use FortiSandbox Appliance with AntiVirus

Feature overview

AntiVirus can use FortiSandbox to supplement its detection capabilities. In real-world situations, networks are always under the threat of zero-day attacks.

AntiVirus can submit potential zero-day viruses to FortiSandbox for inspection. Based on FortiSandbox’s analysis, the FortiGate can supplement its own antivirus database with FortiSandbox’s database to detect files determined as malicious/risky by FortiSandbox. This helps FortiGate’s AntiVirus to detect zero-day virus and malware whose signatures are not found in the FortiGate’s antivirus Database.

Support and limitations

  • FortiSandbox can be used with AntiVirus in both proxy-based and flow-based inspection modes.
  • With FortiSandbox enabled, Full Scan mode AntiVirus can do the following:
  • Submit only suspicious files to FortiSandbox for inspection. l Submit every file to FortiSandbox for inspection.
  • Do not submit anything. l Quick Scan mode AntiVirus cannot submit suspicious files to FortiSandbox. It can only do the following:
  • Submit every file to FortiSandbox for inspection. l Do not submit anything.

Network topology example

Configuring the feature

To configure AntiVirus to work with an external block list, the following steps are required:

  1. Enable FortiSandbox on the FortiGate.
  2. Authorize FortiGate on the FortiSandbox.
  3. Enable FortiSandbox inspection.
  4. Enable use of the FortiSandbox database.

To enable FortiSandbox on the FortiGate:

  1. Go to Global > Security Fabric > Settings.
  2. Set the Sandbox Inspection toggle to the On
  3. Enter the IP address of the FortiSandbox.
  4. Add an optional NotifierEmail if desired.
  5. At this point, selecting Test connectivity will return an unreachable status.

This is expected behavior because the FortiGate is not yet authorized by the FortiSandbox.

  1. Select Apply to save the settings.

To authorize FortiGate on the FortiSandbox:

  1. In the FortiSandbox Appliance GUI, go to Scan Input > Device.
  2. Use the FortiGate serial number to quickly locate the desired FortiGate and select the link icon to authorize the FortiGate.
  3. Enable the desired VDOM in the same manner.
  4. The link icon changes from an open to closed link. This indicates that the FortiSandbox has authorized this FortiGate.
  5. In the FortiGate GUI, go to Global > Security Fabric > Settings.
  6. Select Test connectivity. FortiGate is now authorized and the status now displays as Connected.
  7. FortiSandbox options are now displayed in the AV Profile

To enable FortiSandbox inspection:

  1. Go to Security Profiles > AntiVirus.
  2. Enable FortiSandbox inspection by selecting either Suspicious Files Only or All Supported Files.
  3. Files can be excluded from being sent to FortiSandbox based on their file types by choosing from a list of supported file types.
  4. Files can also be excluded from being sent to FortiSandbox by using wild card patterns.
  5. Select Apply.

To enable use of the FortiSandbox database:

  1. Go to Security Profiles > AntiVirus
  2. Enable use of the FortiSandbox database by setting the Use FortiSandbox Database toggle to the On
  3. Select Apply.

Use FortiSandbox Cloud with AntiVirus

Feature overview

FortiCloud Sandbox allows users to take advantage of FortiSandbox features without having to purchase, operate, and maintain a physical appliance.

FortiCloud Sandbox works the same way as the physical FortiSandbox appliance.

Starting from FortiOS 6.2, the FortiCloud Sandbox allows users to control the region where their traffic is sent to for analysis. This allows users to meet their country’s compliances regarding data’s storage location.

Support and limitations

  • Starting from FortiOS 6.2, users no longer require a FortiCloud account to use FortiCloud Sandbox. l Without a valid AVDB license, FortiGate devices are limited to 100 FortiCloud submissions per day.
  • Unlimited FortiCloud submissions are allowed if the FortiGate has a valid AVDB license.
  • There is a limit on how many submissions are sent per minute.
  • Per minute submission rate is based on the FortiGate model.
  • FortiSandbox can be used with AntiVirus in both proxy-based and flow-based policy inspection modes.
  • With FortiSandbox enabled, Full Scan mode AntiVirus can do the following:
  • Submit only suspicious files to FortiSandbox for inspection. l Submit every file to FortiSandbox for inspection.
  • Do not submit anything. l Quick Scan mode AntiVirus cannot submit suspicious files to FortiSandbox. It can only do the following:
  • Submit every file to FortiSandbox for inspection. l Do not submit anything.

Network topology example

Configuring the feature

To configure AntiVirus to work with an external block list, the following steps are required:

  1. Through FortiCare/FortinetOne, registerthe FortiGate device and purchase a FortiGuard AntiVirus license.
  2. Enable FortiCloud Sandbox on the FortiGate.
  3. Enable FortiSandbox inspection.
  4. Enable the use of the FortiSandbox database.

To obtain or renew an AVDB license:

  1. Please see the video How to Purchase orRenew FortiGuard Services for FortiGuard AntiVirus license purchase instructions.
  2. Once a FortiGuard license has been purchased or activated, users will be provided with a paid FortiSandbox Cloud license.
    1. Go to Global > Main Dashboard to view the FortiSandbox Cloud license indicator.
    2. Users can also view this indicator at Global > System > FortiGuard.

FAQ for Sandbox inspection

The following are some frequently asked questions about using sandbox inspection with FortiSandbox and FortiGate.

Why is the FortiSandbox Cloud option not available when sandbox inspection is enabled?

This option is only available if you have created a FortiCloud account. For more information, see the FortiCloud documentation.

Why don’t results from FortiSandbox Cloud appear in the FortiGate GUI?

Go to Log & Report > Log Settings and make sure Send Logs to FortiCloud is enabled and GUI Preferences is set to Display Logs from FortiCloud.

Why are the FortiSandbox Appliance VMs inactive?

Make sure that port 3 on the FortiSandbox has an active Internet connection. This is required in order to activate the FortiSandbox VMs.

Why aren’t files are being scanned by FortiSandbox?

Make sure an AntiVirus profile that sends files to FortiSandbox is enabled for all policies that require sandbox inspection.

Is FortiSandbox supported by FortiGate when in NAT or Transparent mode?

Yes, a FortiGate can be in either NAT or Transparent mode and support FortiSandbox.

Are FortiGates behind a NAT device supported? If so how many?

Yes, multiple FortiGates can be supported in-line with FortiSandbox. Note that the FortiSandbox will see all FortiGates only as one device so there is no way to differentiate reports.

If the FortiGate has a dynamic IP, will the FortiSandbox automatically update the FortiGate?

Yes. Dynamic IPs are supported and the FortiGate will not have to be reconfigured on the FortiSandbox each time.

What is Sandbox inspection?

What is Sandbox inspection?

Sandbox inspection is a network process that allows files to be sent to a separate device, such as FortiSandbox, to be inspected without risking network security. This allows the detection of threats capable of bypassing other security measures, including zero-day threats.

You can configure your FortiGate device to send suspicious files to FortiSandbox for inspection and analysis. The FortiGate queries scan results and retrieves scan details. The FortiGate can also download malware packages as a complementary AV signature database to block future intrusions by the same malware and download URL packages as complementary web-filtering black lists.

The FortiSandbox uses virtual machines (VMs) running different operating systems to test a file and to determine if it is malicious. If the file exhibits risky behavior, or is found to contain a virus, a new signature can be added to the FortiGuard AntiVirus signature database.

When a FortiGate learns from FortiSandbox that an endpoint is infected, the administrator can quarantine the host, if it is registered to a FortiClient.

FortiSandbox has a VM pool and processes multiple files simultaneously. The amount of time to process a file depends on hardware and the number of sandbox VMs used to scan the file. For example, it can take 60 seconds to five minutes to process a file. FortiSandbox has a robust prefiltering process that, if enabled, reduces the need to inspect every file and reduces processing time. For more information on enabling prefiltering, refer to the FortiSandbox documentation.

Explicit proxy authentication

Leave a reply

Explicit proxy authentication

FortiGate supports multiple authentication methods. This topic explains using an external authentication server with Kerberos as the primary and NTLM as the fallback.

To configure Explicit Proxy with authentication:

Enable and configure the explicit proxy

To enable and configure explicit web proxy in the GUI:

  1. Go to Network > Explicit Proxy.
  2. Enable Explicit Web Proxy.
  3. Select port2 as the Listen on Interfaces and set the HTTP Port to 8080.
  4. Configure the remaining settings as needed.
  5. Click Apply.

To enable and configure explicit web proxy in the CLI:

config web-proxy explicit set status enable set ftp-over-http enable set socks enable set http-incoming-port 8080 set ipv6-status enable

set unknown-http-version best-effort

end

config system interface edit “port2” set vdom “vdom1”

set ip 10.1.100.1 255.255.255.0

set allowaccess ping https ssh snmp http telnet set type physical set explicit-web-proxy enable set snmp-index 12

end

next

end

Configure the authentication server and create user groups

Since we are using an external authentication server with Kerberos authentication as the primary and NTLM as the fallback, Kerberos authentication is configured first and then FSSO NTLM authentication is configured.

For successful authorization, the FortiGate checks if user belongs to one of the groups that is permitted in the security policy.

To configure an authentication server and create user groups in the GUI:

  1. Configure Kerberos authentication:
    1. Go to User& Device > LDAP Servers.
    2. Click Create New.
    3. Set the following:
Name ldap-kerberos
Server IP 172.18.62.220
Server Port 389
Common Name Identifier cn
Distinguished Name dc=fortinetqa,dc=local
  1. Click OK
  1. Define Kerberos as an authentication service. This option is only available in the CLI.
  2. Configure FSSO NTLM authentication:

FSSO NTLM authentication is supported in a Windows AD network. FSSO can also provide NTLM authentication service to the FortiGate unit. When a user makes a request that requires authentication, the FortiGate initiates NTLM negotiation with the client browser, but does not process the NTLM packets itself. Instead, it forwards all the NTLM packets to the FSSO service for processing. a. Go to Security Fabric > Fabric Connectors.

  1. Click Create New and select Fortinet Single Sign-On Agent from the SSO/Identity
  2. Set the Name to FSSO, Primary FSSO Agent to 16.200.220, and enter a password. d. Click OK.
  1. Create a user group for Kerberos authentication:
    1. Go to User& Device > UserGroups.
    2. Click Create New.

Proxy policy addresses

Leave a reply

Proxy policy addresses

Proxy addresses are designed to be used only by proxy policies.

Fast policy match

The fast policy match function improves the performance of IPv4 explicit and transparent web proxies on FortiGate devices.

When enabled, after the proxy policies are configured, the FortiGate builds a fast searching table based on the different proxy policy matching criteria. When fast policy matching is disabled, web proxy traffic is compared to the policies one at a time from the beginning of the policy list.

Fast policy matching is enabled by default, and can be configured with the following CLI command:

config web-proxy global set fast-policy-match {enable | disable} end

Host regex match

In this address type, a user can create a hostname as a regular expression. Once created, the hostname address can be selected on the destination tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the regular expression.

This example creates a host regex match address with the pattern qa.[a-z]*.com.

To create a host regex match address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.
  3. Set the following:

l Category to Proxy Address, l Name to Host Regex, l Type to Host Regex Match, and l Host Regex Pattern to qa.[a-z]*.com.

  1. Click OK.

To create a host regex match address in the CLI:

config firewall proxy-address edit “Host Regex” set uuid 8e374390-57c9-51e9-9353-ee4469629df8

set type host-regex set host-regex “qa.[a-z]*.com”

next

end

URL pattern

In this address type, a user can create a URL path as a regular expression. Once created, the path address can be selected in the destination tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the regular expression.

This example creates a URL pattern address with the pattern /filetypes/.

To create a URL pattern address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.
  3. Set the following:

l Category to Proxy Address, l Name to URL Regex, l Type to URL Pattern, l Host to all, and l URL Path Regex to /filetypes/.

  1. Click OK.

To create a URL pattern address in the CLI:

config firewall proxy-address edit “URL Regex” set uuid 267dc8e4-57cb-51e9-0cfe-27877bff51d3

set type url set host “all” set path “/filetypes/”

next

end

URL category

In this address type, a user can create a URL category based on a FortiGuard URL ID. Once created, the address can be selected in the destination tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the URL category.

The example creates a URL category address for URLs in the Education category. For more information about categories, see https://fortiguard.com/webfilter/categories.

To create a URL category address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.

set type category set host “all” set category 30

next

end

To see a list of all the categories and their numbers, when editing the address, enter set category ?.

HTTP method

In this address type, a user can create an address based on the HTTP request methods that are used. Multiple method options are supported, including: CONNECT, DELETE, GET, HEAD, OPTIONS, POST, PUT, and TRACE. Once created, the address can be selected in the source tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the selected HTTP method.

The example creates a HTTP method address that uses the GET method.

To create a HTTP method address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.
  3. Set the following:

set type method set host “all” set method get

next

end

HTTP header

In this address type, a user can create a HTTP header as a regular expression. Once created, the header address can be selected in the source tab of an explicit proxy policy. This means that a policy will only allow or block requests where the HTTP header matches the regular expression.

This example creates a HTTP header address with the pattern Q[A-B].

To create a HTTP header address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.

set type header set host “all”

set header-name “Header_Test” set header “Q[A-B]”

next

end

User agent

In this address type, a user can create an address based on the names of the browsers that are used as user agents. Multiple browsers are supported, such as Chrome, Firefox, Internet Explorer, and others. Once created, the address can be selected in the destination tab of an explicit proxy policy. This means that a policy will only allow or block requests from the specified user agent.

This example creates a user agent address for Google Chrome.

To create a user agent address in the GUI:

  1. Go to Policy & Objects > Addresses.
  2. Click Create New > Address.

next

end

Advanced (source)

In this address type, a user can create an address based on multiple parameters, including HTTP method, User Agent, and HTTP header. Once created, the address can be selected in the source tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the selected address.

This example creates an address that uses the get method, a user agent for Google Chrome, and an HTTP header with the pattern Q[A-B].

next

end

next

end

Advanced (destination)

In this address type, a user can create an address based on URL pattern and URL category parameters. Once created, the address can be selected in the destination tab of an explicit proxy policy. This means that a policy will only allow or block requests that match the selected address.
