The use case for Transport Layer Security (TLS) is to enable a client and a server to establish secure communications for another protocol. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used for web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, and voice-over-IP (VoIP). TLS operates between the transport layer and the application layer of the Internet Protocol Suite and is used to secure various other protocols like HTTP (resulting in HTTPS), SMTP, IMAP, and more. This protocol ensures privacy and data integrity between two communicating applications. Detailed information about TLS and its use cases can be found in IETF RFC 5246, which outlines the specifications for TLS 1.2, and in subsequent RFCs that define TLS 1.3.

HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to classify endpoints, and one of its profiling methods involves analyzing HTTP User-Agent strings to identify device types (e.g., iPhone, Windows laptop). HTTP User-Agent strings are sent in HTTP headers when a client accesses a website. For CPPM to profile devices using HTTP User-Agent strings, it must receive the HTTP traffic from the clients. In this scenario, the company is using Mobility Controllers (MCs), campus APs, and AOS-CX switches, and CPPM is the only ClearPass solution in use.

HTTP User-Agent Profiling: CPPM can passively profile devices by analyzing HTTP traffic, but it needs to receive this traffic. In an AOS-8 architecture, the MC can mirror client traffic to CPPM for profiling. Since HTTP traffic is part of the data plane (user traffic), the MC must mirror the data plane traffic (not control plane traffic) to CPPM.

Option A, 'Create datapath mirrors that use the CPPM's IP address as the destination,' is correct. The MC can be configured to mirror client HTTP traffic to CPPM using a datapath mirror (also known as a GRE mirror). This involves setting up a mirror session on the MC that sends a copy of the client's HTTP traffic to CPPM's IP address. CPPM then analyzes the HTTP User-Agent strings in this traffic to profile the endpoints. For example, the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http can be used to mirror HTTP traffic to CPPM.

Option B, 'Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM,' is incorrect. IF-MAP (Interface for Metadata Access Points) is a protocol used for sharing profiling data between ClearPass and other systems (e.g., Aruba Introspect), but it is not used for sending HTTP traffic to CPPM for profiling. Additionally, IF-MAP is not relevant when only CPPM is in use.

Option C, 'Create control path mirrors to mirror HTTP traffic from clients to CPPM,' is incorrect. Control path (control plane) traffic includes management traffic between the MC and APs (e.g., AP registration, heartbeats), not client HTTP traffic. HTTP traffic is part of the data plane, so a datapath mirror is required, not a control path mirror.

Option D, 'Create a firewall whitelist rule that permits HTTP and CPPM's IP address,' is incorrect. A firewall whitelist rule on the MC might be needed to allow traffic to CPPM, but this is not the primary step for enabling HTTP User-Agent profiling. The key requirement is to mirror the HTTP traffic to CPPM, which is done via a datapath mirror, not a firewall rule.

The HPE Aruba Networking AOS-8 8.11 User Guide states:

'To enable ClearPass Policy Manager (CPPM) to profile devices using HTTP User-Agent strings, the Mobility Controller (MC) must mirror client HTTP traffic to CPPM. This is done by creating a datapath mirror session that sends a copy of the client's HTTP traffic to CPPM's IP address. For example, use the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http to mirror HTTP traffic to CPPM. CPPM then analyzes the HTTP User-Agent strings to classify endpoints by type (e.g., iPhone, Windows laptop).' (Page 350, Device Profiling with CPPM Section)

Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:

'HTTP User-Agent profiling requires ClearPass to receive HTTP traffic from clients. In an Aruba Mobility Controller environment, configure a datapath mirror to send HTTP traffic to ClearPass's IP address. ClearPass will parse the HTTP User-Agent strings to identify device types and operating systems, enabling accurate profiling.' (Page 249, HTTP User-Agent Profiling Section)

Control Plane Security (CPsec) enhances security in the network by protecting management traffic between APs and Mobility Controllers (MCs) from eavesdropping. CPsec ensures that all control and management traffic that transits the network is encrypted, thus preventing potential attackers from gaining access to sensitive management data. It helps in securing the network's control plane, which is crucial for maintaining the integrity and privacy of the network operations. :

Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.
