ACCESS-DEF CyberArk Defender Access (ACC-DEF) Questions and Answers

 MFA filters can be used in various scenarios within the CyberArk Defender Access environment to enhance security. Specifically, they can be applied to the User and Admin Portal login to ensure that multi-factor authentication is required for access, providing an additional layer of security beyond just a username and password. At the application level, 2FA/MFA can be enforced to protect sensitive applications by requiring users to authenticate with multiple factors before gaining access. Additionally, MFA filters can be utilized for self-service password reset processes, ensuring that users are who they claim to be before allowing them to change their passwords.

References: The information provided is based on the CyberArk Defender Access documentation, which outlines the use of MFA filters in securing access to portals and applications, as well as safeguarding password reset procedures12.

The CyberArk Authenticator desktop application can be installed on both Windows and MacOS operating systems. It is designed to generate Time-based One-Time Passwords (TOTPs) for use in two-factor authentication, providing an additional layer of security for user sign-ins.

References: This information is based on the CyberArk documentation which specifies that the CyberArk Authenticator is compatible with Windows and macOS machines1.

 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.

The App Gateway allows users to access on-premise applications from anywhere without a VPN. For applications that use the App Gateway, the connection from the user travels the same network pathways already in place. CyberArk Identity connects to the CyberArk Identity Connector through the firewall, which then connects to the on-premise directory service for authentication and authorization. This setup simplifies the user experience by allowing them to use the same URL to access the application whether they are on the internal network or outside the corporate network.

The CyberArk Identity mobile app is available for download through official app distribution platforms such as the Apple App Store for iOS devices and Google Play Store for Android devices. These platforms are the standard sources for obtaining mobile applications securely. The Admin Portal is typically used for managing CyberArk solutions and does not distribute mobile apps, the support portal is used for documentation and troubleshooting, and mobile apps are generally not distributed via email attachments due to security risks.

The CyberArk Identity Connector auto-update feature can be managed directly by the IT admin. It can be disabled on the CyberArk Identity Connector server through the configuration window. Additionally, it can also be managed via the CyberArk Identity SaaS Admin Portal under the appropriate settings for network and connectors12.

References: The procedures for managing the CyberArk Identity Connector, including disabling the auto-update feature, are detailed in the CyberArk documentation1. This information is also supported by resources that discuss the exam content for the CyberArk Defender Access (ACC-DEF) certification2.

 In UBA systems, events are typically associated with user accounts, which are identified by usernames. Therefore, to find all events related to a specific user, you would filter by the username associated with that user’s account. The filter user_name ='ivan.helen@acme' would be used to retrieve all events where the username ‘ivan.helen@acme’ is involved.

References: This guidance is based on standard practices for querying event data in UBA systems. For the most accurate and detailed explanation, please refer to the official CyberArk Defender Access (ACC-DEF) study guide and course documentation, which can be found through the CyberArk training portal1.

Within the CyberArk Admin Portal under User Security Policies, the Account Unlock options allow administrators to set policies for how users can unlock their accounts:

• The option to allow for Active Directory users provides the capability for users who utilize Active Directory as their directory service to unlock their own accounts, often necessary after an account has been locked due to multiple failed login attempts.
• The restriction to only allow browsers with an identity cookie helps enhance security by ensuring that account unlock requests come from a browser that has already been recognized by the system, indicating a previous successful login, and thus a lower risk of fraudulent unlock attempts.
• Showing a message to users on the desktop login UI that their account is locked is a direct way to inform users who are attempting to log in from their desktops that their account is currently inaccessible and action may be needed on their part.
• The message explaining the account unlock experience is a user-friendly notification that informs users who have gone through the unlock process that their sign-in experience was different due to the account having been locked and subsequently unlocked, which can be a reminder of the security processes in place and the importance of maintaining secure login credentials.

The Admin Portal: Applications Dashboard is designed to display the applications launched by users, the application type, and the number of times they were launched. This dashboard provides administrators with a useful summary and graphical representations of CyberArk Identity usage, including the total number of app launches over a specified period, which can be instrumental in monitoring and analyzing user activity patterns within an organization.

• CyberArk’s official documentation on viewing dashboards1.
• ExamTopics’ discussion on the CyberArk Defender Access (ACC-DEF) exam questions2.

In the context of UBA systems, the dataset related to updating user profiles would typically be found under the Configuration category. This category generally includes events and data related to system settings, user account configurations, and profile changes. Examining this dataset would allow an investigator to track any alterations made to user profiles, which could be relevant in an incident investigation.

References: This guidance is based on standard practices for managing and analyzing data within UBA systems. For the most accurate and detailed explanation, please refer to the official CyberArk Defender Access (ACC-DEF) study guide and course documentation, which can be found through the CyberArk training portal1.

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.

The “Land and Catch” feature is supported by browsers that are compatible with the CyberArk Identity Browser Extension. This feature allows users to add applications to their User Portal by recognizing when users enter credentials and offering to store the user’s credentials. The supported browsers for this feature are Google Chrome, Firefox, and Microsoft Edge12.

References: The information about supported browsers for the “Land and Catch” feature can be found in the CyberArk public documentation and the CyberArk training resources123. It’s important to note that the Browser Extension for Internet Explorer and Safari is deprecated, which means these browsers are no longer supported for new features like "Land and Catch"2.

In the context of web application connectors:

• OpenID Connect is an identity layer on top of the OAuth 2.0 protocol, which allows for the secure issuance of access tokens representing user identity. It relies on JSON Web Tokens (JWTs) for the identity information of the users, which enables client applications to verify the identity of the end-user based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner.
• Bookmark is a simple type of web app connector that doesn't provide single sign-on (SSO) capabilities. Instead, it acts as a shortcut, allowing users to quickly access web applications or URLs without requiring any form of automated authentication.
• Browser Extension refers to a tool that automates the process of entering a user's credentials into applications that do not support standard SSO protocols. The extension can store the username and password and automatically input these details when the user navigates to the login page of a web application, effectively simulating an SSO experience for non-SSO applications.

CyberArk can enforce Multi-Factor Authentication (MFA) for VPNs using the RADIUS and SAML protocols. This allows organizations to secure remote access to their corporate network, on-premises applications, and resources by applying an additional layer of authentication. For VPNs or VDI solutions that support these protocols, CyberArk’s MFA can be integrated to enhance security. Examples of VPN solutions that support RADIUS or SAML include Cisco, Juniper Networks, Citrix, and Palo Alto Networks. Additionally, SAML can be used to enable single sign-on to a VPN’s web interface, gateways, or portals.

References: CyberArk’s official documentation provides detailed information on how MFA can be applied to VPNs and VDIs, specifically mentioning the support for RADIUS and SAML protocols1.

 Within a Web App connector, the admin uses the Workflow feature to grant users access. Enabling the Workflow feature for an application allows end users to send requests for access to the application to designated users or roles for approval. Approvers can then grant access to the application permanently or for a specified time window. Granting access to the application means the users receive the View, Run, and Automatically Deploy permissions1.

References: The information is based on the CyberArk Defender Access (ACC-DEF) course and learning resources, specifically from the CyberArk documentation on managing application access requests1.

When the “Challenge Pass-Through Duration” is set to “No Pass Through”, it ensures that users are presented with an authentication challenge every time they attempt to access the portal or applications. This setting is crucial for maintaining strict security protocols and ensuring that user identities are verified at each access attempt, preventing unauthorized access and enhancing overall security posture.
