The Block and Allow List policies use site patterns to specify a range of sites that are allowed or blocked. With site patterns, you can allow or block a domain or a range of similar sites without entering each URL separately.
When a user navigates to a site, Web Control compares the URL to the site patterns configured in the assigned Block and Allow List policies.
A site pattern consists of a URL or partial URL, which Web Control interprets as two distinct components:
Domain with protocol information (for example, http://, https://, or ftp://)
Path
Example site pattern: www.trellix.com/us/enterprise
http://www.trellix.com | The domain consists of two parts:
Web Control matches the domain information from the end. A matching URL domain must end with the site pattern’s domain. The protocol can vary.
| ||
/us/enterprise | The path includes everything that follows the slash (/) after the domain. Web Control matches path information from the beginning. A matching URL path must begin with the site pattern’s path.
|
Site patterns must be at least three characters in length and must not include wildcard characters. Web Control doesn't check for matches in the middle or end of URLs.
Use the "." character at the beginning of a site pattern to match a specific domain. For convenience, the "." character causes Web Control to ignore the protocol and introductory characters.
.trellix.com matches these URLs | .trellix.com doesn't match these URLs |
