Wireless Network Security

A security engineer is reviewing the WLAN configuration of a small business that uses WPA2-Personal. The owner wants to raise resistance to offline dictionary attacks against the preshared key without replacing all client hardware. Which two changes best accomplish this goal? (Choose two.)

An administrator observes unauthorized devices connecting to an enterprise wireless network using WPA2-Personal. Which mitigation strategy best prevents credential sharing and ensures unique authentication for every employee?

Which THREE of the following actions are considered best practices when hardening an enterprise wireless infrastructure?

A hospital's wireless network uses WPA2-Enterprise with PEAP-MSCHAPv2. A security engineer discovers that an attacker can capture a client's authentication exchange and crack the password offline. Which change most directly mitigates this specific attack?

A financial services firm deploys 802.1X with EAP-TLS on its corporate WLAN. During an assessment, a consultant captures the 802.11 four-way handshake and observes that the attacker cannot derive the PMK because the exchange never leaves the client and RADIUS-issued credentials exposed. Which property of EAP-TLS best explains why this capture alone cannot be used to impersonate a legitimate client?

A hospital's wireless intrusion prevention system reports that a nearby attacker is broadcasting beacon frames that clone the SSID and BSSID of the hospital's legitimate access point at a higher signal strength, luring staff laptops to associate with the attacker's hardware. Which attack is being described, and which defense most directly addresses it?

A security auditor notices that wireless clients are frequently disconnected by de-authentication frames that contain a spoofed MAC address of the access point. What is the auditor witnessing?

An assessor is standing in a parking lot outside a warehouse and needs to map the coverage footprint and identify all BSSIDs in range, including hidden networks, using a passive approach that does not associate to any AP. Which tool and technique fit this requirement?

A security researcher is evaluating the susceptibility of a WPA3-Personal network to offline dictionary attacks. Which statement accurately describes the resistance provided by WPA3-SAE compared to WPA2-PSK?

Which TWO of the following statements are true regarding the use of WPA3 compared to WPA2?

A retail chain wants to let customers join a guest WLAN without sharing the corporate preshared key, while still keeping guest traffic isolated from point-of-sale systems. Which design best meets these requirements?

A security analyst at a financial firm is reviewing wireless traffic captured near the executive conference room. The capture shows a flood of 802.11 management frames with source addresses set to the company's legitimate AP MAC address, but the frames are not encrypted and are arriving at a high rate. Which type of attack is most likely occurring?

A security administrator is configuring a new wireless intrusion prevention system (WIPS) for a corporate campus. The administrator wants the WIPS to automatically contain an unauthorized access point that is broadcasting the corporate SSID. Which WIPS capability should be enabled to achieve this?

Refer to the exhibit. Which configuration setting poses the most significant risk to the wireless network environment?
