Read the first 7 Wireless & Mobile Security flashcards as text

  1. Which encryption protocol was introduced to replace the vulnerable WEP standard in wireless networks?

    Answer: WPA (Wi-Fi Protected Access)

    WPA was specifically designed as an interim replacement for WEP, using TKIP for stronger encryption while maintaining backward compatibility.

  2. What encryption algorithm does WPA2 use to secure wireless communications?

    Answer: AES with CCMP

    WPA2 uses AES (Advanced Encryption Standard) with CCMP (Counter Mode CBC-MAC Protocol), providing much stronger security than WEP's RC4.

  3. What is a rogue access point in network security?

    Answer: An unauthorized wireless access point installed on a network without admin approval

    A rogue access point is an unauthorized AP connected to a network, which attackers or insiders can use to bypass perimeter security and intercept traffic.

  4. What does SSID stand for in the context of wireless networking?

    Answer: Service Set Identifier

    SSID stands for Service Set Identifier, which is the name that identifies a specific wireless network and is broadcast in beacon frames.

  5. Which IEEE standard defines port-based Network Access Control (NAC) used in enterprise wireless authentication?

    Answer: IEEE 802.1X

    IEEE 802.1X provides port-based NAC, requiring devices to authenticate (often via RADIUS) before gaining network access, commonly used in WPA2-Enterprise.

  6. In a wireless evil twin attack, what does the attacker deploy to capture victim credentials?

    Answer: A malicious access point mimicking a legitimate Wi-Fi network's SSID

    In an evil twin attack, the attacker creates a fake AP with the same SSID as a legitimate network, luring users to connect and then intercepting their traffic or credentials.

  7. What is the primary purpose of disabling SSID broadcasting on a wireless access point?

    Answer: It provides security through obscurity by hiding the network name from passive scans

    Disabling SSID broadcast is a security-through-obscurity measure; the network still exists and can be discovered by active scanning tools, so it provides minimal real protection.
