ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

During a security assessment you capture a four-way handshake from an 802.11g access point running original WPA with a pre-shared key and crack the eight-character passphrase offline. Hardware replacement is delayed, but all existing 802.11g clients support 802.1X. Which configuration change best eliminates this attack vector while preserving client connectivity?

  • Change the network to 128-bit static WEP and rotate the key every week.

  • Disable SSID broadcasting and require clients to connect using manually configured network profiles.

  • Set the TKIP rekey interval to 500 packets to limit the time any single key is valid.

  • Convert the SSID to WPA-Enterprise by enabling 802.1X/EAP authentication and using a RADIUS server to supply dynamic per-session keys.
