A library WLAN still runs SNMPv2c with the community string ‘public’ on APs. What should the designer do?
Select an answer to reveal the explanation.
Short Explanation
‘public’ on SNMPv2c is the spare key hanging on a hook labeled Spare Key. Turn off the old SNMP flavors or move to SNMPv3—do not recycle the Wi-Fi password as the community string.
Full Explanation
Older SNMP versions with default or weak community strings expose management information and control paths. Preventative practice disables SNMPv1/v2c or upgrades to SNMPv3 with stronger authentication and privacy. Reusing WLAN PSKs as community strings or leaving ‘public’ enabled is unsafe.
