Tenable Priority Scanning for CyberArk

Tenable sets a priority system that allows for flexible querying. The following is set out to describe the order Tenable tries values and the logic behind it.

1. Tenable queries CyberArk with the target value entered into the Tenable Targets configuration field. For example, if you put a FQDN in the target list, Tenable queries CyberArk with the address value of the FQDN. If you enter an IP address or range such as 192.0.2.1-20, Tenable tries to query using the IP address or IP range of the target system(s) in the CyberArk Address value. If the target system uses FQDN and can be resolved, then it will be contacted.
2. If the target value fails, Tenable then looks to see if there is a domain value (for a Windows system). If a domain value is present, Tenable queries CyberArk using the domain value for the address value to attempt to use domain credentials.
3. If the configured target value and the domain value both fail, Tenable then pulls the IP address of the system. If the IP address does not match one of the IP addresses supplied in the target list, Tenable then queries CyberArk using the IP address of the target itself. This is checked against the target value in the configuration to prevent querying CyberArk twice with the same value.
