ACCESS-DEF Exam Dumps : CyberArk Defender Access (ACC-DEF)

The requirement is to allow users to authenticate just once if they meet certain authentication criteria. Configuring the QR Code as a "Single Authentication Mechanism" means that if a userauthenticates using the QR Code mechanism, they won't be challenged again. It fulfills the requirement of single authentication by leveraging a secure method that doesn't require subsequent challenges once the QR code is validated. This simplifies the login process while maintaining security by utilizing a secure token that is difficult to replicate or forge.

To minimize the frequency of 2FA/MFA prompts, the following settings are useful:

A.Challenge Pass-Through Duration:This setting allows users to bypass additional MFA prompts for a set period after successfully completing an MFA challenge. For example, if the duration is set to 8 hours, after the user completes MFA once, they won't be prompted again for another 8 hours on the same device.

D.IP Address filter:By whitelisting certain IP addresses, such as those within the corporate network, you can configure policies that do not prompt for MFA when a user is accessing resources from a known and trusted location.

B, C, and E are not related to minimizing MFA prompts. RADIUS is an authentication provider, OATH OTP is an authentication method, and port mapping is unrelated to authentication prompts.

 To mitigate the risk of unauthorized access attempts from a specific IP range, the best practice is to block that range from accessing the CyberArk Identity portal. This can be done by logging into the CyberArk Identity Admin portal and specifying the IP range to be blocked. By doing so, any traffic originating from this range will be denied access, thus reducing the vulnerability and potential for unauthorized access.

References: The information aligns with the best practices for securing access as outlined in the CyberArk documentation, which suggests defining challenge rules for user-added applications or based on the application URL, application domain, or user domain (email) to restrict access1. Additionally, it is consistent with the security guidelines provided by CyberArk, which include implementing measures to contain attacks and prevent unauthorized access2.
