    Get credential by

    The method with which your CyberArk API credentials are retrieved. Can be Username, Identifier, or Address.

    Note: The frequency of queries for Username is one query per target. The frequency of queries for Identifier is one query per chunk. This feature requires all targets have the same identifier.

    Note: The Username option also adds the Address parameter of the API query and assigns the target IP of the resolved host to the Address parameter. This may lead to failure to fetch credentials if the CyberArk Account Details Address field contains a value other than the target IP address.

    		 yes
    Username

    (If Get credential by is Username) The username of the CyberArk user to request a password from.

    		 no
    Safe

    The CyberArk safe the credential should be retrieved from.

    		 no
    Address The option should only be used if the Address value is unique to a single CyberArk account credential. no
    Account Name (If Get credential by is Identifier) The unique account name or identifier assigned to the CyberArk API credential. no

    Use SSL

    If enabled, the scanner uses SSL through IIS for secure communications. Enable this option if CyberArk is configured to support SSL through IIS.

    If enabled, the scanner validates the SSL certificate. Enable this option if CyberArk is configured to support SSL through IIS and you want to validate the certificate.

    CyberArk credential field mapping to the CyberArk Accounts detail view in the CyberArk console:

    Note: The Username option also adds the Address parameter of the API query and assigns the target IP of the resolved host to the Address parameter. This may lead to failure to fetch credentials if the CyberArk Account Details Address field contains a value other than the target IP address.

    Note: Multiple options for Privilege Escalation are supported, including su, su+sudo and sudo. If sudo is selected, additional fields for sudo user, CyberArk Account Details Name and Location of sudo (directory) are provided and can be completed to support authentication and privilege escalation through CyberArk. See the Tenable Security Center User Guide for additional information about the supported privilege escalation types and their accompanying fields.

  6. Configure each field for SSH authentication. See Tenable Security Center User Guide to get detailed descriptions for each option.

  7. Click Submit.
