Per-Request Policy with LTM SSL Forward Proxy

Overview: Adding a per-request policy to LTM SSL forward proxy

If you have an LTM® SSL forward proxy configuration, you can add a per-request policy to it. Every time a client makes a URL request, the per-request policy runs. The policy can contain any available per-request policy action item, including those for URL and application categorization and filtering.

Complete these tasks before you start:

  • Configure any application filters that you want to use.
  • Configure any URL filters (and user-defined URL categories) that you want to use.
  • Configure a per-request policy.
  • Have an LTM SSL forward proxy configuration set up.

Task summary

Creating an access profile for LTM-APM

You create an access profile to provide the access policy configuration for a virtual server that establishes a secured session.
  1. On the Main tab, click Access Policy > Access Profiles .
    The Access Profiles List screen opens.
  2. Click Create.
    The New Profile screen opens.
  3. In the Name field, type a name for the access profile.
    Note: An access profile name must be unique among all access profile and any per-request policy names.
  4. From the Profile Type list, select LTM-APM.
    Additional settings display.
  5. In the Language Settings area, add and remove accepted languages, and set the default language.
    A browser uses the highest priority accepted language. If no browser language matches the accepted languages list, the browser uses the default language.
  6. Click Finished.
    This creates an access profile with a default access policy.
The access profile displays in the Access Profiles List. Default-log-setting is assigned to the access profile.
You can configure the access policy further but you are not required to do so.

Verifying log settings for the access profile

Confirm that the correct log settings are selected for the access profile to ensure that events are logged as you intend.
Note: Log settings are configured in the Access Policy Event Logs area of the product. They enable and disable logging for access system and URL request filtering events. Log settings also specify log publishers that send log messages to specified destinations.
  1. On the Main tab, click Access Policy > Access Profiles .
    The Access Profiles List screen opens.
  2. Click the name of the access profile that you want to edit.
    The properties screen opens.
  3. On the menu bar, click Logs.
    The access profile log settings display.
  4. Move log settings between the Available and Selected lists.
    You can assign up to three log settings that enable access system logging to an access profile. You can assign additional log settings to an access profile provided that they enable logging for URl request logging only.
    Note: Logging is disabled when the Selected list is empty.
  5. Click Update.
An access profile is in effect when it is assigned to a virtual server.

Creating a per-request policy

You must create a per-request policy before you can configure it in the visual policy editor.
  1. On the Main tab, click Access Policy > Per-Request Policies .
    The Per-Request Policies screen opens.
  2. Click Create.
    The General Properties screen displays.
  3. In the Name field, type a name for the policy and click Finished.
    A per-request policy name must be unique among all per-request policy and access profile names.
    The policy name appears on the Per-Request Policies screen.

Processing SSL traffic in a per-request policy

To use SSL forward proxy bypass in a per-request policy, both the server and client SSL profile must enable SSL forward proxy and SSL forward proxy bypass; and, in the client SSL profile, the default bypass action must be set to Intercept.
Important: Configure a per-request policy so that it completes processing of HTTPS requests before it starts the processing of HTTP requests.
Note: These steps describe how to add items for controlling SSL web traffic to a per-request policy; the steps do not specify a complete per-request policy.
  1. On the Main tab, click Access Policy > Per-Request Policies .
    The Per-Request Policies screen opens.
  2. In the Access Policy column for the per-request policy that you want to update, click the Edit link.
    The visual policy editor opens in another tab.
  3. To process the HTTPS traffic first, configure a branch for it by adding a Protocol Lookup item at the start of the per-request policy.
    1. Click the (+) icon anywhere in the per-request policy to add a new item.
      A popup screen opens, listing predefined actions on tabs such as General Purpose, Authentication, and so on.
    2. In the Search field, type prot, select Protocol Lookup, and click Add Item.
      A properties popup screen opens.
    3. Click Save.
      The properties screen closes. The visual policy editor displays.
    The Protocol Lookup item provides two default branches: HTTPS for SSL traffic and fallback.
  4. Before you add an SSL Bypass Set, or an SSL Intercept Set, item to the per-request policy, you can insert any of the following policy items to process SSL traffic:
    • AD Group Lookup
    • LDAP Group Lookup
    • LocalDB Group Lookup
    • RADIUS Class Lookup
    • Dynamic Date Time
    • Logging
    • Category Lookup
      Important: Category Lookup is valid for processing SSL traffic only when configured for SNI or Subject.CN categorization input and only before any HTTP traffic is processed.
    If you insert other policy items that inspect the SSL payload (HTTP data) before an SSL Bypass Set item, the SSL bypass cannot work as expected.
  5. At any point on the HTTPS branch where you decide to bypass SSL traffic, add an SSL Bypass Set item.
The per-request policy includes items that you can use to complete the processing of SSL traffic. Add other items to the policy to control access according to your requirements.
A per-request policy goes into effect when you add it to a virtual server.

Configuring policies to branch by local database user group

If you plan to look up local database groups from the per-request policy, you must configure local database-related items in the access policy and the per-request policy to use the same session variable.
  1. On the Main tab, click Access Policy > Access Profiles .
    The Access Profiles List screen opens.
  2. In the Access Policy column, click the Edit link for the access profile you want to configure.

      A new line is added to the list of entries with the Action set to Read and other default settings.
    3. In the Destination column in the Session Variable field, type the name of the variable in which to store the user groups retrieved from the local database.
      In the per-request policy, the default value that the LocalDB Group Lookup item uses is session.localdb.groups. If you enter a differentvalue, note it. You will need it to update the advanced expression in the LocalDB Group Lookup item in the per-request policy.
    4. In the Source column from the DB Property list, select groups.
    5. Click Save.
      The properties screen closes. The visual policy editor displays.
    This is not a complete access policy, but you can return to it and complete it later. You can close the visual policy editor or leave it open.

    A popup properties screen opens.
  10. Click the Branch Rules tab.
  11. Click the change link in the entry for the default expression.
    A popup screen opens.
  12. If the session variable you typed in the access policy Local Database action was session.localdb.groups, perform these substeps.
    1. In the User is a member of field, remove MY_GROUP and type the name of a group.
    2. Click Finished.
      The popup screen closes.
    3. Click Save.
      The properties screen closes and the visual policy editor displays.
  13. If you typed a session variable other than session.localdb.groups in the access policy Local Database action, perform these substeps.
    1. Click the Advanced tab.
      In the field, this expression displays. expression is expr { [mcget {session.localdb.groups}] contains "MY_GROUP" }
    1. In the expression, replace session.localdb.groups with the name of the session variable you typed into the Local Database action.
    2. In the expression, replace MY_GROUP with the name of a group that should match a local database group.
    3. Click Finished.
      The popup screen closes.
    4. Click Save.
      The properties screen closes and the visual policy editor displays.
    This is not a complete per-request access policy, but you can return to it and complete it later.
The access and per-request policies are configured to use the same session variable. The access policy is configured to support the use of LocalDB Group Lookup in the per-request policy.
Complete the configuration of the access and per-request policies.

Categorizing URLs using custom categories in a per-request policy

Important: These steps apply to a BIG-IP® system on which URL categories are available only by creating them in Access Policy Manager® (APM®).
If you haven't configured URL categories and URL filters yet in APM, configure them before you start this task.
Look up the category for a URL request and use it in a policy branch rule, or to assign a URL filter, and so on.
Note: These steps provide guidance for adding items to control traffic based on the URL category; they do not specify a complete per-request policy.
  1. On the Main tab, click Access Policy > Per-Request Policies .
    The Per-Request Policies screen opens.
  2. In the Access Policy column for the per-request policy that you want to update, click the Edit link.
    The visual policy editor opens in another tab.
  3. Add a Category Lookup item and set its properties:
    Important: A Category Lookup item triggers event logging for URL requests and provides categories for a URL Filter Assign item.
    1. From the Categorization Input list, select an entry based on the type of traffic to be processed. .
      • For HTTP traffic, select Use HTTP URI (cannot be used for SSL Bypass decisions).
      • For SSL-encrypted traffic, select Use SNI in Client Hello (if SNI is not available, use Subject.CN).
      • Use Subject.CN in Server Cert is not supported for reverse proxy.
    2. For Category Lookup Type, you can only retain the default setting Process custom categories only.
    1. Click Save.
      The properties screen closes. The visual policy editor displays.
  4. To add a URL Filter Assign item, do so anywhere on a branch after a Category Lookup item.
    A URL filter applies to the categories that a Category Lookup item returns. If the filter specifies the Block action for any URL category, URL Filter Assign blocks the request.
    Note: If URL Filter Assign does not block the request and the filter specifies the confirm action for any URL category, URL Filter Assign takes the Confirm per-request policy branch and the policy exits on the ending for it.
    1. From the URL Filter list, select a URL filter.
    2. To simplify the display in the visual policy editor if the URL filter does not specify confirm actions, select Branch Rules, and click x on the Confirm entry.
    3. Click Save.
      The properties screen closes and the visual policy editor displays.
Now the per-request policy includes an item that looks up the URL category. You can add other items to the policy to control access according to your requirements.
Note: SSL bypass and SSL intercept are not supported when you are protecting internal resources from incoming requests. They are supported in a forward proxy configuration.
A per-request policy goes into effect when you add it to a virtual server.

Configuring a per-request policy to control access to applications

Access Policy Manager® (APM®) supports a preset group of application families and applications. You can configure your own application filters or use one of the filters that APM provides: block-all, allow-all, and default.
Configure a per-request policy to specify the logic that determines whether to allow access to the applications or application families.
Note: This task provides the steps for adding items to control requests based on the application name or application family or based on an application filter. It does not specify a complete per-request policy.

    The popup screen closes. The visual policy editor displays.
A per-request policy goes into effect when you add it to a virtual server.

Creating a DNS resolver

You configure a DNS resolver on the BIG-IP® system to resolve DNS queries and cache the responses. The next time the system receives a query for a response that exists in the cache, the system returns the response from the cache.
  1. On the Main tab, click Network > DNS Resolvers > DNS Resolver List .
    The DNS Resolver List screen opens.
  2. Click Create.
    The New DNS Resolver screen opens.
  3. In the Name field, type a name for the resolver.
  4. Click Finished.

Adding forward zones to a DNS resolver

Before you begin, gather the IP addresses of the nameservers that you want to associate with a forward zone.

Add a forward zone to a DNS resolver when you want the BIG-IP® system to forward queries for particular zones to specific nameservers for resolution in case the resolver does not contain a response to the query.
Note: Creating a forward zone is optional. Without one, a DNS resolver can still make recursive name queries to the root DNS servers; however, this requires that the virtual servers using the cache have a route to the Internet.
  1. On the Main tab, click Network > DNS Resolvers > DNS Resolver List .
    The DNS Resolver List screen opens.
  2. Click the name of the resolver you want to modify.

  5. In the Name field, type the name of a subdomain or type the fully qualified domain name (FQDN) of a forward zone.
    For example, either example or site.example.com would be valid zone names.
  6. Add one or more nameservers:
    1. In the Address field, type the IP address of a DNS nameserver that is considered authoritative for this zone.
      Based on your network configuration, add IPv4 or IPv6 addresses, or both.
    2. Click Add.
      The address is added to the list.
    Note: The order of nameservers in the configuration does not impact which nameserver the system selects to forward a query to.
  7. Click Finished.

Adding a DNS resolver to the http-explicit profile

An HTTP profile defines the way that you want the BIG-IP®system to manage HTTP traffic.
Note: APM® provides a default http-explicit profile for Secure Web Gateway (SWG) explicit forward proxy. You must add a DNS resolver to the profile.
  1. On the Main tab, click Local Traffic > Profiles > Services > HTTP .
    The HTTP profile list screen opens.
  2. Click the http-explicit link.
    The Properties screen displays.
  3. Scroll down to the Explicit Proxy area.
  4. From the DNS Resolver list, select the DNS resolver you configured previously.
  5. Ensure that you retain the default values for the Tunnel Name and Default Connect Handling fields.
    The default value for Tunnel Name is http-tunnel. The default value for Default Connect Handling is Deny.
  6. Click Finished.

Updating the virtual server for SSL forward proxy

To add per-request processing to an LTM® SSL forward proxy configuration, associate the access profile, custom HTTP profile, and per-request policy with the virtual server.

  1. On the Main tab, click Local Traffic > Virtual Servers .
    The Virtual Server List screen opens.
  2. Click the name of the virtual server that is configured for LTM SSL forward proxy.
    SSL client and server profiles that are configured specifically for SSL forward proxy are associated with this virtual server.
  3. From the HTTP Profile list, select http-explicit.
  4. From the HTTP Profile list, select the HTTP profile you configured earlier.
  5. In the Access Policy area, from the Access Profile list, select the access profile that you configured earlier.
  6. From the Per-Request Policy list, select the per-request policy that you configured earlier.
  7. Click Update.
The access policy and per-request policy are now associated with the virtual server.

Overview: SSL forward proxy client and server authentication

With the BIG-IP® system's SSL forward proxy functionality, you can encrypt all traffic between a client and the BIG-IP system, by using one certificate, and to encrypt all traffic between the BIG-IP system and the server, by using a different certificate.

A client establishes a three-way handshake and SSL connection with the wildcard IP address of the BIG-IP system virtual server. The BIG-IP system then establishes a three-way handshake and SSL connection with the server, and receives and validates a server certificate (while maintaining the separate connection with the client). The BIG-IP system uses the server certificate to create a second unique server certificate to send to the client. The client receives the second server certificate from the BIG-IP system, but recognizes the certificate as originating directly from the server.

Important: To enable SSL forward proxy functionality, you can either:
  • Disassociate existing Client SSL and Server SSL profiles from a virtual server and configure the SSL Forward Proxy settings.
  • Create new Client SSL and Server SSL profiles and configure the SSL Forward Proxy settings.
Then with either option, select the Client SSL and Server SSL profiles on a virtual server. You cannot modify existing Client SSL and Server SSL profiles while they are selected on a virtual server to enable SSL forward proxy functionality.
A virtual server configured with Client and Server SSL profiles for SSL forward proxy     functionality

A virtual server configured with Client and Server SSL profiles for SSL forward proxy functionality

  1. Client establishes three-way handshake and SSL connection with wildcard IP address.
  2. BIG-IP system establishes three-way handshake and SSL connection with server.
  3. BIG-IP system validates a server certificate (Certificate A), while maintaining the separate connection with the client.
  4. BIG-IP system creates different server certificate (Certificate B) and sends it to client.

Task summary

To implement SSL forward proxy client-to-server authentication, as well as application data manipulation, you perform a few basic configuration tasks. Note that you must create both a Client SSL and a Server SSL profile, and enable the SSL Forward Proxy feature in both profiles.

Task list

Creating a custom Client SSL forward proxy profile

You perform this task to create a Client SSL forward proxy profile that makes it possible for client and server authentication while still allowing the BIG-IP® system to perform data optimization, such as decryption and encryption.
