Selena has decided to change a 32-character unique wireless network name on her wireless router to improve network security after a break-in. She is following advice from CERT to make this change in…

Question

Options

• ADirect Sequence Spread Spectrum (DSSS) signal
• BMedia Access Control (MAC) address
• CWi-Fi Protected Access 2 (WPA2)
• DService Set Identifier (SSID)

• A
  4% (1)
• C
  4% (1)
• D
  92% (24)

Explanation

D is correct because the SSID (Service Set Identifier) is exactly the wireless network name - the 32-character string that identifies a Wi-Fi network to devices. Changing a default or easily guessable SSID is a standard hardening step recommended by CERT to reduce botnet targeting, since many botnets scan for routers left with factory-default network names.

Why the distractors are wrong:

• A (DSSS) is a radio transmission technique that spreads the signal across frequencies - it's a physical-layer method, not a configurable network name setting.
• B (MAC address) is a hardware identifier burned into a network adapter; while MAC filtering is a security feature, the MAC address itself is not a "network name" and isn't what you rename for identification purposes.
• C (WPA2) is an encryption/authentication protocol - it secures the password and data, not the network's name.

Memory tip: Think of SSID as the network's "name tag" - it's what you see when your phone scans for Wi-Fi. The "S" in SSID stands for "Set," as in the set (group) of devices sharing that network identity. If the question mentions changing a wireless network name, the answer is almost always SSID.
