An organization wants to enhance its network security by integrating external systems to provide rich context to its authorization logic. They plan to use ClearPass Policy Manager for this purpose. Which feature of the Policy Manager will be most beneficial for integrating with these external systems?
ClearPass is designed as an open platform. The External Context Server feature allows ClearPass to exchange data with third-party security systems like Firewalls (Palo Alto, Check Point), EMM/MDM (Intune, AirWatch), and SIEMs (Splunk). By using REST APIs or XML/JSON over HTTP, ClearPass can send 'Context Server Actions' (like telling a firewall to quarantine a user) or receive data to be used as attributes in authorization policies.
An organization is setting up a ClearPass server for their network authentication. The administrator has installed a certificate issued by an internal Certificate Authority. The clients cannot fully validate the server's certificate. What additional step must the administrator take to ensure the clients can successfully validate the certificate?
Certificate trust is hierarchical. For a client device to trust a server certificate, it must trust the Root CA that signed it. If an internal CA is used, its root certificate is not present in the default trust stores of consumer devices. Therefore, the administrator must deploy that root certificate to every client (typically via GPO, MDM, or Onboard) so they can successfully verify the identity of the ClearPass server during the EAP handshake.
A network administrator is configuring a new Network Access Device (NAD) in ClearPass. They select RadSec for the network device and notice that the PSK field automatically changes to 'radsec' regardless of what is typed. What is the most likely reason for this behavior?
As discussed in Q5, RadSec utilizes TLS for security, which renders the traditional RADIUS MD5 shared secret obsolete. In the ClearPass interface, when RadSec is selected as the protocol, the system automatically defaults the PSK to 'radsec' because the underlying communication is now secured by certificates, not a password. This is a standard behavior of the protocol implementation in HPE Aruba products to indicate that certificate-based trust is now the priority.
A company wants to ensure that all BYOD devices undergo a health check before gaining full access to the network. They plan to use ClearPass OnGuard for this purpose. Given that they have a guest network where devices initially connect to an open guest SSID before full authentication, which agent should they use?
The Dissolvable Agent is ideal for BYOD and Guest scenarios where you cannot mandate that users install permanent software on their personal devices. When a user connects to the guest portal, the agent is downloaded as a temporary executable, runs the required Health Checks, reports the results back to ClearPass, and then removes itself from the system. This provides security without the administrative overhead of managing software installations on non-corporate hardware.
A web developer is tasked with creating a series of web pages with a unified look and feel using ClearPass Guest. The pages must mirror the company's internal website. Which type of skin should they use?
While ClearPass provides built-in skins that allow for basic logo and color changes, achieving a pixel-perfect mirror of an existing corporate website usually requires a Fully Custom Skin. These skins allow developers to upload custom CSS, HTML headers/footers, and JavaScript to match the exact 'look and feel' of the brand's main site. These are often provided as specialized plugins or professional service packages to ensure compatibility across different browser types.
