A network security consultant is conducting an audit of an organization's multi-generational wireless network infrastructure. Match each wireless security requirement or vulnerability scenario to its corresponding cryptographic protocol or mechanism.
- High-security corporate requirement enforcing WPA3 192-bit mode (Suite B compliance)Galois/Counter Mode Protocol with 256-bit key length (GCMP-256)
- WPA3-Personal pre-shared key replacement designed to prevent offline dictionary attacksSimultaneous Authentication of Equals (SAE) based on Dragonfly key exchange
- Standard WPA2 mandatory encryption cipher providing authenticated data encryptionCounter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP)
- Legacy WEP integrity check mechanism susceptible to unauthenticated message modificationCyclic Redundancy Check (CRC-32) Integrity Check Value
Answer
High-security WPA3 192-bit mode matches GCMP-256; WPA3-Personal pre-shared key replacement matches SAE; WPA2 mandatory encryption matches CCMP; Legacy WEP integrity check matches CRC-32.
WPA3 192-bit mode specifies GCMP-256 for top-tier government and enterprise security; WPA3-Personal utilizes SAE (Dragonfly) to protect passphrase-based connections; WPA2 relies on CCMP (AES-CCMP) for default confidentiality and integrity; WEP's integrity checksum relies on linear CRC-32 which is easily manipulated by attackers.
