Simple Network Management Protocol monitors and manages network devices like routers, switches, and servers. SNMP agents on devices expose management data through a structured hierarchy called a MIB. Managers poll agents for status information or receive traps (alerts) when thresholds are exceeded.

Why SNMP Matters for Your Cybersecurity Career

SNMP versions 1 and 2c transmit community strings in plaintext, making them easy targets for credential theft. Attackers who obtain SNMP write access can reconfigure network devices remotely. Security engineers must ensure SNMP v3 with encryption and authentication is enforced across all network infrastructure.
