Restricted SaaS access (Office 365, G Suite, Dropbox)

With the web proxy profile, you can specify access permissions for Microsoft Office 365, Google G Suite, and Dropbox. You can insert vendor-defined headers that restrict access to the specific accounts. You can also insert custom headers for any destination.

You can configure the web proxy profile with the required headers for the specific destinations, and then directly apply it to a policy to control the header's insertion.

To implement Office 365 tenant restriction, G Suite account access control, and Dropbox network access control:

1. Configure a web proxy profile according to the vendors' specifications:
   1. Define the traffic destination (service provider).
   2. Define the header name, defined by the service provider.
   3. Define the value that will be inserted into the traffic, defined by your settings.
2. Apply the web proxy profile to a policy.

The following example creates a web proxy profile for Office 365, G Suite, and Dropbox access control.

Due to vendors' changing requirements, this example may no longer comply with the vendors' official guidelines.

To create a web proxy profile for access control using the CLI:

1. Configure the web proxy profile:

   config web-proxy profile
      edit "SaaS-Tenant-Restriction"
           set header-client-ip pass
           set header-via-request pass
           set header-via-response pass
           set header-x-forwarded-for pass
           set header-front-end-https pass
           set header-x-authenticated-user pass
           set header-x-authenticated-groups pass
           set strip-encoding disable
           set log-header-change disable
           config headers
               edit 1
                   set name "Restrict-Access-To-Tenants"  <---header name defined by Office365 spec. input EXACTLY as it is
                   set dstaddr "Microsoft Office 365" <----built-in destination address for Office365
                   set action add-to-request
                   set base64-encoding disable
                   set add-option new
                   set protocol https http
                   set content "contoso.onmicrosoft.com,fabrikam.onmicrosoft.com"  <----your tenants restriction configuration
               next
               edit 2
                   set name "Restrict-Access-Context"  <----header name defined by Office365 spec. input EXACTLY as it is
                   set dstaddr "Microsoft Office 365"  <----build-in destination address for Office365
                   set action add-to-request
                   set base64-encoding disable
                   set add-option new
                   set protocol https http
                   set content "456ff232-35l2-5h23-b3b3-3236w0826f3d" <----your directory ID can find in Azure portal
               next
               edit 3
                   set name "X-GooGApps-Allowed-Domains"  <----header name defined by Google G suite.
                   set dstaddr "G Suite"  <---- built-in G Suite destination address
                   set action add-to-request
                   set base64-encoding disable
                   set add-option new
                   set protocol https http
                   set content "abcd.com"    <----your domain restriction when you create G Suite account
               next
   
               edit 4
                   set name "X-Dropbox-allowed-Team-Ids" <----header defined by Dropbox
                   set dstaddr "wildcard.dropbox.com"  <----build-in destination address for Dropbox
                   set action add-to-request
                   set base64-encoding disable
                   set add-option new
                   set protocol https http
                   set content "dbmid:FDFSVF-DFSDF"  <----your team-Id in Dropbox 
               next
           end
       next
   end

2. Apply the web proxy profile to a firewall policy:

   config firewall policy
       edit 1
           set name "WF"
           set srcintf "port10" "wifi"
           set dstintf "port9"
           set srcaddr "all"
           set dstaddr "all"
           set action accept
           set schedule "always"
           set service "ALL"
           set webproxy-profile "SaaS-Tenant-Restriction"
           set utm-status enable
           set utm-inspection-mode proxy
           set logtraffic all
           set webfilter-profile "blocktest2" 
           set application-list "g-default"
           set profile-protocol-options "protocol"
           set ssl-ssh-profile "protocols"
           set nat enable
       next
   end
