Purpose

Specifies a host name for certificate validation when SSL encryption is enabled and validation is enabled (ValidateServerCertificate=true). This property is optional and provides additional security against man-in-the-middle (MITM) attacks by ensuring that the server the driver is connecting to is the server that was requested.

Valid Values

host_name

where:

host_name

is a valid host name.

Behavior

If host_name is specified, the driver compares the specified host name to the DNSName value of the SubjectAlternativeName in the certificate. If the certificate does not have a SubjectAlternativeName, the driver compares the host name with the Common Name (CN) part of the certificate. If the values do not match, the connection fails and the driver throws an exception.

Notes

  • If SSL encryption or certificate validation is not enabled, this property is ignored.
  • If SSL encryption and validation is enabled and this property is unspecified, the driver uses the server name that is specified in the connection URL or data source of the connection to validate the certificate.
