When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using Valid SSID," the next step is to locate the general area of the threat. You can use HPE Aruba Networking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network. This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.

Internet Key Exchange (IKE)/IKEv2 plays a crucial role in an HPE Aruba Networking client-to-site VPN by helping to negotiate the IPsec Security Association (SA) automatically and securely. IKE/IKEv2 handles the authentication and key exchange processes, ensuring that both the client and the VPN gateway can establish a secure IPsec tunnel.

1.SA Negotiation: IKE/IKEv2 automates the negotiation of the Security Association, which defines the parameters for the secure IPsec tunnel.

2.Secure Authentication: It provides a secure method for authenticating the communicating parties and exchanging cryptographic keys.

3.Efficiency: Using IKE/IKEv2 simplifies the setup and maintenance of secure VPN connections, enhancing the overall security and reliability of the VPN.

Integration of CPDI and CPPM for Zero Trust:

CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.

CPDI can tag devices based on their behavior or detected applications.

CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).

Option Analysis:

Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.

Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.

Option C: Incorrect. Custom fingerprint definitions are not part of this integration.

Option D: Incorrect. CPDI provides information about devices, not user identities.

When using "Tips

" conditions within an 802.1X service's enforcement policy, you should enable caching roles and posture attributes from previous sessions in the service's enforcement settings. This ensures that ClearPass retains posture information from previous authentications, which is necessary for making decisions based on the current posture state of an endpoint. By caching these attributes, ClearPass can apply appropriate enforcement actions based on the device's posture status.

Syslog Integration with CPPM:

ClearPass Policy Manager (CPPM) can integrate with third-party firewalls via Syslog messages to detect and respond to internal threats.

The Syslog integration enables CPPM to gather context on suspicious activity and enforce appropriate policies such as isolating attackers by working with network devices like Aruba switches and APs.

Option A: Correct. This method allows for dynamic response to threats and leverages existing infrastructure without requiring major reconfiguration.

Option B: Incorrect. CPDI is primarily used for profiling devices, not directly for threat response based on Syslog information.

Option C: Incorrect. While it is possible for CPPM to poll information, this approach is less dynamic and not focused on immediate threat response.

Option D: Incorrect. Tunnel mode SSIDs and UBT are designed for forwarding user traffic securely but do not directly enhance threat detection or mitigation.

ClearPass Device Profiler gathers information (DHCP, HTTP user-agent, MAC OUI, RADIUS, etc.) to identify device types and roles—especially non-user devices. Aruba documentation describes using profiling to recognize and categorize devices such as IP cameras, printers, and IoT “bots”, and to supply this identity context to access control policies. ExamTopics

Typical use cases include:

Automatically identifying a device as a security camera, printer, IP phone, etc.

Using that profile to assign an appropriate role/VLAN and enforcement profile in CPPM (e.g., restricted video-surveillance VLAN).

ClearPass literature explicitly calls out that Device Profiler is used to “automatically profile devices and provide an identity context (such as cameras, printers, or bots)” that can be used in policy decisions.

Options B, C, and D are handled by vulnerability scanners, directory services, or posture/OnGuard, not by Device Profiler itself. Therefore the correct use case is Option A.

ClearPass OnGuard uses a Posture Policy object to define:

Which checks are performed (e.g., AV installed, firewall status, patches)

How the results map to posture tokens such as “Healthy,” “Quarantined,” etc.

The official OnGuard configuration workflow states that you must first “Define the posture policy”, and that these posture policies contain the rules for evaluating health and determining posture tokens.

Service enforcement policies then consume the posture token (e.g., Tips:Posture = Healthy) but do not define the posture conditions themselves. The “Posture” tab on a service is used to enable posture and associate it with the posture policy; the detailed rules live in the posture policy object.

Therefore, posture logic is defined by creating rules within a posture policy → Option A.
