How do I add rules to the Sandbox policy?
If you have the Cloud Sandbox subscription, you can add rules to the policy. You can configure different rules in your Sandbox policy to apply to different sets of users or to different locations. See also the recommended Sandbox policy.
To add a rule:
- Go to Policy > Web > Sandbox.
- Click Add Sandbox Rule.
- In the Edit Sandbox Rule window, complete the following:
- Rule Order: Policy rules are evaluated in ascending numerical order (Rule 1 before Rule 2, and so on), and the Rule Order reflects this rule's place in the order. You can change the value, but if you've enabled Admin Rank, your assigned admin rank determines the Rule Order values you can select.
Admin Rank: This option appears if you enabled the Admin Rank feature in the Advanced Settings page.
Enter a value from 1-7 (1 is the highest rank). Your assigned admin rank determines the values you can select. You cannot select a rank that is higher than your own. The rule's Admin Rank determines the value you can select in Rule Order, so that a rule with a higher Admin Rank always precedes a rule with a lower Admin Rank.
- Rule Status: Choose to Enable or Disable the rule. An enabled rule is actively enforced. A disabled rule is not actively enforced and doesn't lose its place in the Rule Order scheme. The service simply skips it and moves to the next rule.
File Types: Select the file type(s) to which the rule applies. The file types you can select for your Sandbox policy include the following:
- Windows Executable
- Windows Library
- Microsoft Excel
- Microsoft PowerPoint
- Microsoft RTF
- Microsoft Word
- Android Application Package
- PDF Document
- Adobe Flash
- Java Applet
- URL Categories: Select Any to select all URL categories, or select specific URL categories. You can search for URL categories or click the Add icon to add a new category.
- Users: Select Any to apply the rule to all users, or select up to 4 users under General Users. If you've enabled the unauthenticated users policy, you can select Special Users to apply this rule to all unauthenticated users, or select specific types of unauthenticated users. You can search for users or click the Add icon to add a new user.
- Groups: Select Any to apply the rule to all groups, or select up to 8 groups. You can search for groups or click the Add icon to add a new group.
- Departments: Select Any to apply the rule to all departments, or select any number of departments. If you've enabled the unauthenticated users policy, you can select Special Departments to apply this rule to all unauthenticated transactions. You can search for departments or click the Add icon to add a new department.
- Locations: Select Any to apply the rule to all locations, or select up to 8 locations. You can also search for a location or click the Add icon to add a new location. To apply this rule to unauthenticated traffic, the rule must apply to all locations.
Sandbox Categories: Select the type(s) of malicious files:
- Sandbox Adware refers to files that automatically render advertisements/install adware.
