Certificate name wildcards
SyslogDefender and SyslogSender support wildcards in certificate common names (CNs) and in X.509v3 Subject Alternative Names (SANs). The left-most subdomain name can use an asterisk as a wildcard character in its right-most position.
The following table shows matching and non-matching names and wildcards:
Server Domain Name or Client verify_name | Certificate CN or SAN | Matches? |
|---|---|---|
Server5.YourCo.com | *.YourCo.com | Yes |
Server5.YourCo.com | Server*.YourCo.com | Yes |
www.Server.YourCo.com | *.YourCo.com | No The wildcard matches against only one subdomain name. |
YourCo.com | *.YourCo.com | No The wildcard does not match an omitted subdomain name. |
any | www.*.YourCo.com | No The wildcard must be in the left-most position of the subdomain name. |
any | *Server.YourCo.com | No The wildcard must be in the right-most position of the subdomain name. |
