The exhibit shows a screenshot of a Malwarebytes alert that indicates that a website was blocked due to compromise. The alert contains the following information:

• The type of protection: Web Protection
• The website that was blocked: 10.254.1.21
• The port that was used: 80
• The process that initiated the connection: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
• The IP address of the device that initiated the connection: 10.1.26.151

The IP address of the device that initiated the connection is the one that should be recorded as a possibly compromised client, as it indicates that the device tried to access a malicious website that could infect it with malware or steal its data. In this case, the IP address of the possibly compromised client is 10.1.26.151.

 This is because an Endpoint Context Server (ECS) is a feature that allows ClearPass to receive contextual information from external sources, such as Aruba Central, and use it for policy enforcement and reporting. An ECS can be configured to point to the Aruba Central API and fetch data such as device type, category, OS, applications, traffic flows, etc.

An ECS can be used to communicate the information that an IoT client has used SSH to Aruba ClearPass Policy Manager (CPPM). The ECS can query the Aruba Central API and retrieve the network traffic flows of the wireless IoT devices that are categorized as “Raspberry Pi” clients. The ECS can then filter the traffic flows by the SSH protocol and send the relevant information to CPPM. CPPM can then use this information for policy decisions, such as allowing or denying SSH access, or triggering alerts or actions.

B. On CPPM enable Device Insight integration. This is not a valid step because Device Insight is a feature that allows ClearPass to discover, profile, and fingerprint devices on the network using deep packet inspection (DPI) and machine learning (ML). Device Insight does not communicate with Aruba Central or receive information from it. Moreover, Device Insight might not be able to detect SSH traffic on encrypted wireless IoT devices without decrypting it first.

C. On Central configure APs and gateways to use CPPM as the RADIUS accounting server. This is not a valid step because RADIUS accounting is a feature that allows network devices to send periodic updates about the status and activity of authenticated users or devices to a RADIUS server, such as CPPM. RADIUS accounting does not communicate with Aruba Central or receive information from it. Moreover, RADIUS accounting might not be able to capture SSH traffic on wireless IoT devices without inspecting it first.

D. On Central set up CPPM as a Webhook application. This is not a valid step because Webhook is a feature that allows Aruba Central to send notifications or events to external applications or services using HTTP requests. Webhook does not communicate with CPPM or send information to it. Moreover, Webhook might not be able to send SSH traffic information on wireless IoT devices without filtering it first.

Aruba Central supports site-to-site VPNs between AOS 10 gateways, which are Aruba devices that provide routing, firewall, and VPN functions. Aruba Central can automatically provision and manage the site-to-site VPNs using the VPN Manager feature. The VPN Manager allows you to create VPN groups that consist of one or more hubs and branches, and define the VPN settings for each group1

Aruba Central uses IPsec as the protocol to secure the site-to-site connections between the AOS 10 gateways. IPsec is a standard protocol that provides encryption, authentication, and integrity for IP packets. Aruba Central automatically establishes IPsec tunnels for all site-to-site connections using keys that are securely distributed by Central. The keys are generated by Central and pushed to the gateways using a secure channel. The keys are rotated periodically to enhance security2
