Pre-defined filters
Your software includes several sample category, protocol, and cloud app filters. You can use these filters as they are, or modify them. If you do not need the predefined filters, many of them can also be deleted. Delete a filter by selecting it in the list on the Filters page and clicking Delete.
The predefined category filters are:
- Basic
- Basic Security
- Block All
- Default
- Monitor Only
- Permit All
- Strict Security
The Block All and Permit All category filters are not listed on the Filters page, though they can be added to policies. These filters are handled differently than the others, and cannot be deleted or edited. When Filtering Service receives an Internet request, it first checks to see if the Block All or Permit All filter applies, before performing any additional checks (see Responding to a URL request). The predefined protocol filters are:
- Basic Security
- Default
- Monitor Only
- Permit All
The Permit All protocol filter, like its equivalent category filter, is not listed on the Filters page and cannot be edited or deleted. It is also prioritized during the policy enforcement process.
The predefined cloud app filters are:
- Basic Security
- Monitor Only (used as the default filter)
The Default filters can be edited, but cannot be deleted. In upgrade environments, if there are gaps in the Default policy, the Default filters are used to filter requests during periods when no other filter applies.
