Transparent web proxy (386474)

In addition to the Explicit Web Proxy, FortiOS now supports a Transparent web proxy. While it does not have as many features as Explicit Web Proxy, the transparent proxy has the advantage that nothing needs to be done on the user’s system to forward supported web traffic over to the proxy. There is no need to reconfigure the browser or publish a PAC file. Everything is transparent to the end user, hence the name. This makes it easier to incorporate new users into a proxy deployment.

You can use the transparent proxy to apply web authentication to HTTP traffic accepted by a firewall policy. In previous versions of FortiOS, web authentication required using the explicit proxy.

Normal FortiOS authentication is IP address based. Users are authenticated according to their IP address and access is allowed or denied based on this IP address. On networks where authentication based on IP address will not work you can use the Transparent Web proxy to apply web authentication that is based on the user’s browser and not on their IP address. This authentication method allows you to identify individual users even if multiple users on your network are connecting to the FortiGate from the same IP address.

Using the Transparent proxy

To implement the Transparent proxy, go to System > Settings and scroll down to Operations Settings and set the inspection mode to Proxy.

Then go to System > Feature Visibility and enable Explicit Proxy.

Then go to Security Profiles > Proxy Options, edit a proxy options profile and under Web Options enable HTTP Policy Redirect.

Then go to Policy & Objects > IPv4 Policy and create or edit a policy that accepts traffic that you want to apply web authentication to. This can be a general policy that accepts many different types of traffic as long as it also accepts the web traffic that you want to apply web authentication to.

Select a Security Profile and select the Proxy Options profile that you enabled HTTP Policy Redirect for.

 

Using the Transparent proxy

Then go to Policy & Objects > Proxy Policy create a Transparent Proxy policy to accept the traffic that you want to apply web authentication to. Set the Proxy Type to Transparent Web. The incoming interface, outgoing interface, destination address, and schedule should either match or be a subset of the same options defined in the IPv4 policy. Addresses added to the Source must match or be a subset of the source addresses added to the IPv4 policy. You can also add the users to be authenticated by the transparent policy to the source field.

Select other transparent policy options as required.

More about the transparent proxy

The following changes are incorporated into Transparent proxy, some of which affect Explicit Web Proxy as well.

Flat policies

The split policy feature has been removed. This will make the explicit policy more like the firewall policy.

Authentication

The new authentication design is intended to separate authentication from authorization. Authentication has been moved into a new table in the FortiOS. This leaves the authorization as the domain of the explicit proxy policy.

Previously, if authentication was to be used:

1. The policy would be classified as an identity based policy
2. The policy would be split to add the authentication parameters
3. The authentication method would be selected
4. The user/group would be configured Now:

The user/group is configured in the proxy policy

1. A new authentication rule is added
2. This option refers to the authentication scheme
3. The authentication scheme has the details of the authentication method The new authentication work flow for Transparent Proxy:

Toggle the transparent-http-policy match:

config firewall profile-protocol-options edit <profile ID> config http set http-policy <enable|disable>

If disabled, everything works like before. If enabled, the authentication is triggered differently.

• http-policy work flow:
• For transparent traffic, if there is a regular firewall policy match, when the Layer 7 check option is enabled, traffic will be redirected to WAD for further processing.
• For redirected traffic, layer 7 policy (HTTP policy) will be used to determine how to do security checks.
• If the last matching factor is down to user ID, then it will trigger a new module to handle the L7 policy user authentication.
• Then propagate learned user information back to the system so that it can be used to match traffic for L4 policy.

New Proxy Type

There is a new subcategory of proxy in the proxy policy called Transparent Web. The old Web Proxy is now referred to as Explicit Web Proxy.

• This is set in the firewall policy l It is available when the HTTP policy is enabled in the profile-protocol options for the firewall policy l This proxy type supports OSI layer 7 address matching.
• This proxy type should include a source address as a parameter l Limitations:
• It can be used for HTTPS traffic, if deep scanning is not used l It only supports SNI address matching, i.e. domain names
• It does not support header types of address matching l It only supports SSO authentication methods, no active authentication methods.

IP pools support

Proxies are now supported on outgoing IP pools.

SOCKSv5

SOCKSv5 authentication is now supported for explicit proxies.

To configure:

config authentication rule edit <name of rule> set protocol socks end

Forwarding

Proxies support URL redirect/forwarding. This allows a non-proxy forwarding server to be assigned a rule that will redirect web traffic from one URL to another, such as redirecting traffic destined for youtube.com to restrict.youtube.com.

l A new option called “Redirect URL” has been added to the policy l Traffic forwarding by VIP is supported

Support for explicit proxy address objects & groups into IPv4 firewall policies

This would allow the selection of web filter policy, SSL inspection policy, and proxy policy based on source IP + destination (address|explicit proxy object|category|group of any of those). This enables things like “do full SSL interception on www.google.com, but not the rest of the Search Engines category”.

Support application service in the proxy based on HTTP requests.

The application service can be configured using the following CLI commands:

config firewall service custom edit <name of service> set explicit-proxy enable set app-service-type <disable|app-id|app-category> set app-category <application category ID, integer> set application <application ID, integer> end

Security Fabric Audit and Fabric Score

This chapter contains information about the Security Fabric Audit and Fabric Score, which together provide a method to continually monitor and improve your Security Fabric’s configuration.

What is the Security Fabric Audit?

The Security Fabric Audit is a feature on your FortiGate that allows you to analyze your Security Fabric deployment to identify potential vulnerabilities and highlight best practices that could be used to improve your network’s overall security and performance.

Why should you run a Security Fabric Audit?

Using the Security Fabric Audit helps you to tune your network’s configuration, deploy new hardware and/or software, and gain more visibility and control of your network. Also, by checking your Security Fabric Score, which is determined based on how many checks your network passes/fails during the Audit, you can have confidence that your network is getting more secure over time.

Running a Security Fabric Audit

The Security Fabric Audit can be found by going to Security Fabric > Audit. In the first step, all detected FortiGates are shown.

Running a Security Fabric Audit

In the second step, the audit is performed and a list of recommendations are shown. Two views are available: Failed or All Results. These views can be further segmented so that you view results from all FortiGates or just a specific unit.

In each view, a chart appears showing the results of individual checks. The following information is shown: the name and a description of the check, which FortiGate the check occurred on, the checks result on your overall security score, and any necessary recommendations.

If you hover the mouse over the Result for a check, you can get a breakdown on how this score was determined.

For more information about this, see “Security Fabric Score” on page 38.

Logging for the Security Fabric Audit

In Step Three of the Audit, Easy Apply recommendations are displayed and can be applied. By using Easy Apply, you can change the configuration of any FortiGate in the fabric.

For other recommendations, further action is required if you wish to follow the recommendation.

You can also view Audit recommendations for specific devices using the FortiView Topology consoles. If a recommendation is available for a device, a circle containing a number appears. The number shows how many recommendations are available, while the color of the circle shows the severity of the highest check that failed (red is critical, orange is high, yellow is medium, and blue is low).

Logging for the Security Fabric Audit

An event filter subtype is available for the Security Audit. Every time an audit is run, event logs are created on the root FortiGate that summarize the results of the audit, as well as details into the individual tests.

Security Fabric Audit Checks

Syntax

config log eventfilter set security-audit {enable | disable} (enabled by default)

Security Fabric Audit Checks

The Security Fabric Audit performs a variety of checks when analyzing your network. All checks are based on your current network configuration, using realtime monitoring. The Audit runs these checks across all FortiGates in the Security Fabric.

Security Fabric Score

The Security Fabric Score widget has been added to the FortiGate Dashboard to give visibility into auditing trends. This widget uses information from the Security Fabric Audit to determine your score. Score can be positive or negative, with a higher score representing a more secure network.

Score is based on the number of checks failed and the severity of these checks. The weight for each severity level is as follows:

l Critical: 50 points l High: 25 points l Medium: 10 points l Low: 5 points

You get points for passing a test only when it passes for all FortiGates in your fabric. If this occurs, the score is calculated using this formula:

+Severity Weight x Secure FortiGate Multiplier

The Severity Weight is calculated as Severity divided by the number of FortiGates in the Fabric. The Secure FortiGate Multiplier is determined using logarithms and the number of FortiGates in the fabric. For example, if you have four FortiGates in your fabric that all pass the Compatible Firmware check, your score for each individual FortiGate is:

(50/4) x 1.292 = 16.2 points

If a test fails on any FortiGate in your Fabric, all other FortiGates that passed the check award 0 points. For the FortiGate the test failed on, the score is calculated using this formula:

-Severity Weight x Count

Count is the number of times the check failed during the audit. For example, if two critical FortiClient vulnerabilities are discovered during the Audit, your score for that check is:

-50 x 2 = -100 points

 

For checks that do not apply, your score does not change. For example, if you have no FortiAPs in the fabric, you will receive no points for the FortiAP Firmware Versions check.

New Security Fabric features

In FortiOS 5.6, the Security Fabric (previously known as the Cooperative Security Fabric) has been expanded in several ways to add more functionality and visibility.

One of the most important functional changes is that FortiAnalyzer is now a required part of the Security Fabric configuration. Also, two important new features, Security Fabric Audit and Fabric Score, have been added to provide a method to continually monitor and improve the Security Fabric configuration.

Many changes have been made through FortiView to improve the visibility of the Security Fabric. More information is now displayed and you can access downstream FortiGates directly from the root FortiGate’s FortiView display.

Other smaller improvements have been made throughout the Security Fabric, with a focus on improving communication between devices.

In FortiOS 5.6.1, the new updated GUI design consolidates the Security Fabric features together under a new menu and has many new topological changes to provide greater visibility into the connectivity of your networked devices. This includes adding more Fortinet products to the topology and widgets. Other topology improvements include enhanced IPsec VPN detection (which now includes detection of downstream FortiGates) and support for SD-WAN. Smaller changes have also been made to add more information to device tooltip alerts in the Physical and Logical Topology views.

Setting up the Security Fabric in FortiOS 5.6

See the following FortiGate Cookbook recipes to get started in setting up the Security Fabric in FortiOS 5.6:

l Installing a FortiGate in NAT/Route mode l Security Fabric installation

Security Fabric between remote networks by enabling FortiTelemetry for IPsec VPN interfaces

You can now enable FortiTelemetry for IPsec VPN interfaces. The Security Fabric can now detect the downstream FortiGate through the IPsec VPN interface. This allows you to send FortiTelemetry communication over a Gateway-to-Gateway IPsec VPN tunnel between two remote networks. One of the networks would contain the root FortiGate and the network at the other end of the IPsec VPN tunnel can connect to the root FortiGate’s Security Fabric.

In the GUI, to enable FortiTelemetry

1. Go to Network > Interfaces and edit your IPsec VPN interface.
2. Under Administrative Access enable FortiTelemetry.

 

New Security Fabric Security Fabric between remote networks by enabling FortiTelemetry for IPsec VPN features          interfaces

Your IPsec VPN interface will automatically be added to the FortiTelemetry enabled interface list under Security Fabric > Settings.

In the CLI, enter the following commands:

config system interface edit <vpn_name> set fortiheartbeat enable

end

Re-designed Security Fabric setup

A new updated GUI menu consolidates the Security Fabric features in one location. This includes Physical Topology, Logical Topology, Audit, and Settings. For more details, see the illustration below:

Security Fabric between remote networks by enabling FortiTelemetry for IPsec VPN interfaces

New Security Fabric features

Improved Security Fabric Settings page

The Security Fabric Settings page has been updated to act as a centralized location for you to enable connectivity to other Fortinet products. Navigate to Security Fabric > Settings.

Changes to the Settings page include the following:

l The previous Enable Security Fabric option has been replaced with an option to enable FortiGate Telemetry. l The previous Downstream FortiGates option has been replaced with Topology to show multiple devices.

See the screen shot below:

Security Fabric dashboard widgets

Security Fabric dashboard widgets

New dashboard widgets for the Security Fabric put information about the status of the Security Fabric at your fingertips when you first log into your FortiGate.

The FortiGate dashboard widget has been updated to include the following Fortinet products: FortiGate (core), FortiAnalyzer (core), FortiSwitch, FortiClient, FortiSandbox, and FortiManager. See the screen shot below:

You can hover over the icons along the top of the Security Fabric widget to get a quick view of the status of the Security Fabric. Available information includes the FortiTelemetry status and the status of various components of in the Security Fabric.

The Security Fabric Score widget shows the Security Fabric Audit score for the Security Fabric and allows you to apply recommended changes right from the dashboard.

 

Physical and Logical FortiView improvements

Physical and Logical FortiView improvements

The FortiView Physical and Logical Topology pages now display the following improvements:

• Shows both FortiGates in an HA configuration l Shows FortiAPs l Lists FortiAnalyzer and FortiSandbox as components of the Security Fabric l Highlights the current FortiGate l Displays Link Usage in different colors l Ranks Endpoints by FortiClient Vulnerability Score and by Threat Score ( see below, for more information) l Displays user avatars l Recognizes servers as a device type

• Introduces a search bar to help locate specific devices in the Security Fabric

Updated Physical and Logical Topology legend

On the Physical Topology and Logical Topology pages, the Security Fabric legend has been updated. See the screenshot below:

Physical and Logical FortiView improvements

New option to minimize the Topology

This new feature allows you to minimize portions of the Physical and Logical Topology. This makes it easy to view your entire topology, or minimize portions to focus in on a specific area. See the screenshot below:

Security Fabric Topology shows new resource information alerts

The enhanced Security Fabric topology now shows CPU Usage and Memory Usage alerts in the device information tooltip. It also displays a warning if the FortiGate is in conserve mode. Note that the CPU usage, memory usage and conserve mode data are drawn from the data that was last loaded from the FortiGate, not real-time data.

You can see the new CPU Usage and Memory Usage fields shown in the tooltip below:

Physical and Logical FortiView improvements

The Conserve mode warning is shown below:

SD-WAN information added to Security Fabric topology

The Security Fabric topology now includes SD-WAN. Enhancements include greater visibility into where the data comes from and goes to, link saturation indicators, and detailed tooltip explanations. The following SD-WAN information has been integrated into the Security Fabric topology:

• The tooltip for the SD-WAN interface now includes load balancing settings. l In the Security Fabric Logical Topology, SD-WAN and its interface members will appear above all interfaces.
• If connected to an upstream FortiGate, one link between the exact SD-WAN member and the upstream FortiGate will appear.
• If connected to a destination bubble, links between each enabled member and the destination bubble appear.
• Interface bandwidth and link utilization for other interfaces (WAN role interface) have been temporarily removed and will be added back in later.
• Fixes have been made to show vulnerabilities for multiple MAC addresses (402495) and to show the FortiSwitch serial and port (389158).

For more details see the screenshot below:

 

FortiCache support for the                      (435830)

SD-WAN Monitor Support added to Security Fabric (417210)

The Security Fabric now retrieves monitor information from all members of the Security Fabric and displays it in the GUI of the root FortiGate. Support was added for the Routing Monitor, DHCP Monitor and User Quarantine Monitor.

You can use the new drop down menu shown below to select the Security Fabric members:

FortiCache support for the Security Fabric (435830)

FortiGates in the Security Fabric can now use FortiCache as a remote cache service. Previously, FortiCache was supported via WCCP re-direct only, but now FortiGates can use it as a local cache rather than redirecting via WCCP.

In the GUI, follow the steps below:

1. Go to Security Fabric > Settings and enable HTTP Service.

Enhanced Security Fabric audit tests for FortiGuard licenses (409156)

2. Set Device Type to FortiCache and add the IP addresses of the FortiCache devices.
3. You can also select Authentication and add a password if required. See the screenshot below:

In the CLI, enter the following commands:

config wanopt forticache-service set status enable

set local-cache-id <local-cache-id> set remote-forticache-id <remote-forticache-id> set remote-forticache-ip <remote-forticache-ip>

end

l status – Enable/disable using FortiCache as web-cache storage l disable – Use local disks as web-cache storage l enable – Use a remote FortiCache as web-cache storage l local-cache-id – The cache ID that this device uses to connect to the remote FortiCache l remote-forticache-id – The ID of the FortiCache that the device connects to l remote-forticache-ip – The IP address of the FortiCache the device connects to

Enhanced Security Fabric audit tests for FortiGuard licenses (409156)

The Security Fabric audit now has separate audit tests for FortiGuard licenses based on whether the FortiGuard license is valid, expired, never been activated, or temporarily unavailable. Previously, the audit test performed one batch test on all FortiGuard licenses, regardless of the status of the licenses. Recommendations for individual licenses are also provided in the GUI tooltips.

You can see the new breakdown of pass or fail actions shown below:

• License valid = pass l License expired = fail l License never activated = fail
• License is unavailable (connection issue with FortiGuard) = pass

If a required Feature Visibility is disabled, the audit test for it will not show vulnerabilities. The audit will show a score of zero (or a pass). Go to System > Feature Visibility (previously the Feature Select menu) to make any changes.

FortiClient Vulnerability Score

In the GUI, follow the steps below to check the status of your FortiGuard licenses:

1. Go to Security Fabric > Audit to check the status of your FortiGuard licenses.
2. Follow the steps in the Security Fabric Audit wizard.
3. Expand Firmware & Subscriptions, and look at the FortiGuard License Subscriptions section to verify whether any recommended action is required. See the example below:

FortiClient Vulnerability Score

Endpoints in the Security Fabric topology are now ranked by their FortiClient Vulnerability Score. This score is calculated by the severity of vulnerabilities found on the endpoint:

l critical vulnerability = 100 points l high vulnerability = 50 points l medium vulnerability = 5 points l low vulnerability = 2 points l info vulnerability = 1 point

FortiView Consolidation

Information about the Security Fabric can now be seen throughout the FortiView dashboards on the upstream FortiGate, when the real-time view is used.

• You can right-click on an entry and select View Aggregated Details to see more information.
• The upstream FortiGate filters information to avoid counting traffic from the same hosts multiple times on each hop.

The upstream FortiGate also now has the option to end downstream FortiGate sessions or quarantine endpoints that connect to downstream FortiGates.

Remote login to downstream FortiGates

Remote login to downstream FortiGates

You can now log into downstream FortiGates from the upstream FortiGate, by right-clicking on the downstream FortiGate when viewing the Security Fabric’s topology using FortiView.

Logging Consolidation and Improvements

Several changes have been made to improve logging for a Security Fabric.

Sending all logs to a single FortiAnalyzer

By default, all FortiGates in the Security Fabric now send logs to a single FortiAnalyzer. The connection to the FortiAnalyzer is configured on the upstream FortiGate, then the settings are pushed to all other FortiGates.

In FortiOS 5.6, a FortiAnalyzer is required for the root FortiGate in the Security Fabric; however, downstream devices can be configured to use other logging methods through the CLI:

config system csf set logging-mode local

The entire Security Fabric tree is now updated upward, and each node has an updated state of the whole subtree. The content is saved in the local file and upon request from the GUI or a diagnose command (dia sys csf downstream) it can be retrieved.

 

What is the Security Fabric Audit?

Executive Summary

This chapter briefly highlights some of the higher profile new FortiOS 5.6 features, some of which have been enhanced for FortiOS 5.6.1.

Security Fabric enhancements

Security Fabric features and functionality continue to evolve. New features include improved performance and integration, a security audit function that finds possible problems with your network and recommends solutions, security fabric dashboard widgets, improved device detection, and the remote login to other FortiGates on the fabric. See New Security Fabric features on page 20.

Security Fabric Audit

The Security Fabric Audit allows you to analyze your Security Fabric deployment to identify potential vulnerabilities and highlight best practices that could be used to improve your network’s overall security and performance. See Security Fabric Audit and Fabric Score on page 32.

Re-designed Dashboard

The Dashboard has been enhanced to show more information with greater flexibility and more functionality. See New Dashboard Features on page 40 for details.

NGFW Policy Mode

You can operate your FortiGate in NGFW policy mode to simplify applying Application control and Web Filtering to firewall traffic. See NGFW Policy Mode (371602) on page 57.

Flow-based inspection with profile-based NGFW mode is the default inspection mode in FortiOS 5.6.

Transparent web proxy

In addition to the Explicit Web Proxy, FortiOS now supports a Transparent web proxy. You can use the transparent proxy to apply web authentication to HTTP traffic accepted by a firewall policy.
