Creating an Internet Access Control Rule

Configure an internet access control rule to protect your users' internet access whether they are on or off your corporate network.

Note:

Trend Micro Vision One automatically creates a default internet access rule to apply whenever no other internet access rules are matched. The default rule allows unrestricted access to the internet.

  1. On the Secure Access Rules screen, click the Internet Access Control tab and then click Create Rule.

    The rule configuration screen appears with the Web access control rule template selected.

  2. Specify a unique name and a description for the rule.
  3. (Optional) To enable or disable the rule, click the toggle next to Status.
    Tip:

    You can also enable or disable rules on the Internet Access Control tab.

  4. Configure the following rule factors.

    Rule Factor

    Description

    Options

    Source

    The users and locations that the rule applies to

    Users / Groups / Private IP groups

    • Users / Groups: Specify users and user groups from your IAM system.

      Note:

      If you have configured more than one IAM system, the IAM system with SSO enabled applies.

    • Private IP groups: Specify private IP address groups within your organization.

      A private IP address group references the IP addresses or segments on the internal corporate network that share the same egress IP address. You can define a private IP address group to identify a sub-location within a corporate network location. You can then use these sub-locations to implement different internet access rules for the corporate network location, regardless of which users are accessing from these internal IP addresses.

      Note:
      • The selected private IP address group must be a subset of at least one corporate network location.

      • Internet access rules may not apply in the following situation because the Internet Access Gateway cannot retrieve private IP addresses: Devices are not installed with the Secure Access Module and HTTP/HTTPS requests do not contain the X-Forwarded-For (XFF) header field to carry the device IP address.

      • To define a new IP group using one or more private IP addresses on your internal corporate network, click Add private IP address group.

    Locations

    Specify corporate network locations, or public/home network locations with specified IP addresses or geographic regions.

    • Corporate network locations identify user traffic from known locations, such as the corporate headquarters, a branch office, or company VPN. Corporate network locations access the internet through a specified Internet Access Gateway.

      Tip:

      To define your corporate network locations on the Internet Access Cloud Gateway or through an Internet Access On-Premises Gateway, go to Secure Access Configuration > Internet Access Configuration and configure settings on the Gateways tab.

    • Public/home network locations identify roaming users, such as users connecting to public Wi-Fi networks or working from home. Public/home network locations are defined by IP address or geographic region.

      Tip:

      To define a new public/home network location using one or more IP addresses, click Add public IP address group.

    Traffic

    The internet content that the rule applies to

    URLs/Cloud apps

    • Expand URL categories and apply the rule to URL categories predefined by Trend Micro or customized by the admin.

    • Expand Custom cloud app categories and apply the rule to cloud app categories predefined by Trend Micro or customized by the admin.

      For more information, see Custom Cloud App Categories.

    • Expand Custom cloud app actions and apply the rule to actions within apps. For example, you can block file downloads from Facebook.

    Schedule

    The weekly period that the rule is applied

    To configure the recurrence of the schedule, select Only apply the rule during the specified period, and then select a start date and end date.
