Opportunistic Wireless Encryption (OWE) is a WPA3 feature designed for open wireless networks, where no password or authentication is required to connect. OWE enhances security by providing encryption for devices that support it, without requiring a pre-shared key (PSK) or 802.1X authentication.

Option C, "It allows anyone to connect, but provides better protection against eavesdropping than a traditional open network," is correct. In a traditional open network (no encryption), all traffic is sent in plaintext, making it vulnerable to eavesdropping. OWE allows anyone to connect (as it’s an open network), but it negotiates unique encryption keys for each client using a Diffie-Hellman key exchange. This ensures that client traffic is encrypted with AES (e.g., using AES-GCMP), protecting it from eavesdropping. OWE in transition mode also supports non-OWE devices, which connect without encryption, but OWE-capable devices benefit from the added security.

Option A, "It allows both WPA2-capable and WPA3-capable clients to authenticate to the same WPA-Personal WLAN," is incorrect. OWE is for open networks, not WPA-Personal (which uses a PSK). WPA2/WPA3 transition mode (not OWE) allows both WPA2 and WPA3 clients to connect to the same WPA-Personal WLAN.

Option B, "It offers more control over who can connect to the wireless network when compared with WPA2-Personal," is incorrect. OWE is an open network protocol, meaning it offers less control over who can connect compared to WPA2-Personal, which requires a PSK for access.

Option D, "It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MITM) attacks," is incorrect. OWE provides encryption to prevent eavesdropping, but it does not protect against honeypot APs (rogue APs broadcasting the same SSID) or MITM attacks, as it lacks authentication mechanisms to verify the AP’s identity. Protection against such attacks requires 802.1X authentication (e.g., WPA3-Enterprise) or other security measures.

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

"Opportunistic Wireless Encryption (OWE) is a WPA3 feature for open networks that allows anyone to connect without a password, but provides better protection against eavesdropping than a traditional open network. OWE uses a Diffie-Hellman key exchange to negotiate unique encryption keys for each client, ensuring that traffic is encrypted with AES-GCMP and protected from unauthorized interception." (Page 290, OWE Overview Section)

Additionally, the HPE Aruba Networking Wireless Security Guide notes:

"OWE enhances security for open WLANs by providing encryption without requiring authentication. It allows any device to connect, but OWE-capable devices benefit from encrypted traffic, offering better protection against eavesdropping compared to a traditional open network where all traffic is sent in plaintext." (Page 35, OWE Benefits Section)

EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) and PEAP (Protected EAP) are two EAP methods used for 802.1X authentication in wireless networks, such as those configured with WPA3-Enterprise on HPE Aruba Networking solutions. Both methods are commonly used with ClearPass Policy Manager (CPPM) for secure authentication.

EAP-TLS:

Requires both the supplicant (client) and the server (e.g., CPPM) to present a valid certificate during authentication.

Establishes a TLS tunnel to secure the authentication process, but the primary authentication mechanism is the mutual certificate exchange. The client’s certificate is used to authenticate the client, and the server’s certificate authenticates the server.

PEAP:

Requires only the server to present a certificate to authenticate itself to the client.

Establishes a TLS tunnel to secure the authentication process, within which the client authenticates using a secondary method, typically a username and password (e.g., via MS-CHAPv2 or EAP-GTC).

Option A, "EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of its process," is incorrect. Both EAP-TLS and PEAP establish a TLS tunnel. In EAP-TLS, the TLS tunnel is used for the mutual certificate exchange, while in PEAP, the TLS tunnel protects the inner authentication (e.g., username/password).

Option B, "EAP-TLS requires the supplicant to authenticate with a certificate, but PEAP allows the supplicant to use a username and password," is correct. This is a key difference: EAP-TLS mandates certificate-based authentication for the client, while PEAP allows the client to authenticate with a username and password inside the TLS tunnel, making PEAP more flexible for environments where client certificates are not deployed.

Option C, "EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake," is incorrect. Both methods use a TLS tunnel, and both authenticate the server during the TLS handshake (using the server’s certificate). In EAP-TLS, the client’s certificate is also part of the TLS handshake, while in PEAP, the client’s credentials (username/password) are sent inside the tunnel after the handshake.

Option D, "EAP-TLS creates a TLS tunnel for transmitting user credentials securely, while PEAP protects user credentials with TKIP encryption," is incorrect. PEAP does not use TKIP (Temporal Key Integrity Protocol) for protecting credentials; TKIP is a legacy encryption method used in WPA/WPA2 for wireless data encryption, not for EAP authentication. PEAP uses the TLS tunnel to protect the inner authentication credentials.

The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:

"EAP-TLS requires both the supplicant and the server to present a valid certificate for mutual authentication. The supplicant authenticates using its certificate, and the process is secured within a TLS tunnel. In contrast, PEAP requires only the server to present a certificate to establish a TLS tunnel, within which the supplicant can authenticate using a username and password (e.g., via MS-CHAPv2 or EAP-GTC). This makes PEAP more suitable for environments where client certificates are not deployed." (Page 292, EAP Methods Section)

Additionally, the HPE Aruba Networking Wireless Security Guide notes:

"A key difference between EAP-TLS and PEAP is the client authentication method. EAP-TLS mandates that the client authenticate with a certificate, requiring certificate deployment on all clients. PEAP allows the client to authenticate with a username and password inside a TLS tunnel, making it easier to deploy in environments without client certificates." (Page 40, 802.1X Authentication Methods Section)

An ArubaOS user role determines the firewall policies and bandwidth contracts that apply to the client’s traffic. When a user is authenticated, they are assigned a role, and this role has associated policies that govern network access rights, Quality of Service (QoS), Layer 2 forwarding, Layer 3 routing behaviors, and bandwidth contracts for users or devices.
