Which of the following are items that can be configured on a wireless router to make it more difficult for attackers to gain access? (Select TWO).
- A.
Change the wireless channel
- B.
Disable SSID broadcast
- C.
Change SSID from default
- D.
Enable DES encryption
- E.
Turn on port forwarding
Correct Answer(s)
B. Disable SSID broadcast
C. Change SSID from defaultExplanation
Disabling SSID broadcast and changing the SSID from default are two items that can be configured on a wireless router to make it more difficult for attackers to gain access. Disabling SSID broadcast prevents the router from broadcasting its network name, making it less visible to potential attackers. Changing the SSID from default adds an extra layer of security as attackers often target routers with default settings. By changing the SSID, the attacker would need to spend more time figuring out the network name, making it harder for them to gain access.Rate this question:
