Web: Example for Using URL Filtering and Application Control Together

Networking Requirements

As shown in Figure 1, the FW is deployed at the network border as the enterprise's gateway to implement URL filtering on HTTPS requests of employees. The detailed requirements are as follows:
  • Enterprise employees can access only Facebook in the social networking category and cannot access other websites.
  • Employees of the marketing department can access the Facebook website and all Facebook applications. Employees of the R&D department can access only the Facebook website but cannot use other Facebook applications, such as email and chat.

To meet the requirements, URL filtering and application control must be used together. URL filtering controls employees to access only Facebook but not other websites. Application control implements refined control on the access to Facebook applications.

Figure 1 Using URL filtering and application control together

Configuration Roadmap

  1. Set interface IP addresses and assign the interfaces to security zones.
  2. Create the URL filtering profile url_profile_all to allow enterprise employees to access Facebook in the social networking category and prohibit the access to other websites.
  3. Configure the security policy policy_sec_all and reference the URL filtering profile url_profile_all to control the URL access of all employees in the enterprise.
  4. Configure the security policy policy_sec_marketing to allow employees in the marketing department to access Facebook and all Facebook applications.

    To control lower-level Facebook applications, you need to configure SSL-encrypted traffic detection.

  5. Configure the security policy policy_sec_research to control employees in the R&D department to access only the Facebook website but not other Facebook applications, such as email and chat.
