SNMP
Simple Network Management Protocol
A protocol for monitoring and managing network devices.
SNMP lets administrators monitor and configure routers, switches, printers, and servers by polling values and receiving asynchronous trap notifications. Versions 1 and 2c are insecure because they pass community strings as clear text, effectively unencrypted passwords that attackers can sniff or guess, and default strings like public and private are a frequent finding. SNMPv3 adds authentication and encryption and should be preferred. The exam emphasizes hardening SNMP by disabling old versions and replacing default credentials.
Looking SNMP up is step one. Getting tested on it is step two.
