[Certificate]
| This subkey stores SSL/TLS certificates configuration values.
|
DestinationCertPreference | This value is of type REG_SZ, and defines the required level of SSL/TLS certificate verification when connecting to a remote destination server. Note: SSL/TLS certificate verification is not relevant if UDP or TCP protocols are used to connect to the destination. Accepted values are:
ANY - (Default) Require an SSL/TLS certificate to be presented, but accept the certificate even if the chain of trust cannot be authenticated, or the hostname does not match the presented certificate. This is useful for self-signed certificates.
STRICT - Require an SSL/TLS certificate to be presented, and have both a valid chain of trust and also a hostname matching the certificate. A hostname must be provided in the associated Destination#Host setting, as an IP address will not work. |
DestinationCertPreferenceSAM | This value is of type REG_SZ, and defines the required level of SSL/TLS certificate verification when connecting to a Snare Agent Manager server. Accepted values are:
ANY - (Default) Require an SSL/TLS certificate to be presented, but accept the certificate even if the chain of trust cannot be authenticated, or the hostname does not match the presented certificate. This is useful for self-signed certificates.
STRICT - Require an SSL/TLS certificate to be presented, and have both a valid chain of trust and also a hostname matching the certificate. A hostname must be provided in the SAM1IP setting, as an IP address will not work. |
WebCertID | The thumbprint of the certificate to be used for HTTPS web user interface interactions. By default, Snare Agent generates a self-signed certificate. Customer is welcome to replace it with a CA-signed certificate for improved security. |
