ALT The image shows a comparison of three types of Simple Network Management Protocols (SNMP). SNMPv1 and SNMPv2c are marked with red "X" symbols, indicating disapproval. SNMPv3 is marked with a green check mark, indicating approval.
ALT An infographic comparing SNMPv1/v2c and SNMPv3. The left side, labeled SNMPv1 & SNMPv2c, highlights clear-text protocol, lack of strong protection, and easy interception of sensitive data. The right side, labeled SNMPv3, emphasizes encryption, stronger authentication, and enhanced network security.

ALT The image displays a table titled "Cisco Password Types." It lists password types from 0 to 9, detailing the ability to crack, vulnerability severity, and NSA recommendation for each. Some types are labeled as "Do not use," while others are "Recommended" or have conditional approval.
ALT The image displays a list titled "SMI Mitigation Actions" with a background of a gear and network motif. The list includes: 1) Disable Smart Install auto-loading feature on all network devices. 2) Review Cisco switch configuration files for deviations from documented pre-existing configurations. 3) Implement deny by default strategy at edge firewall devices and ensure TFTP (UDP port 69) and SMI (TCP port 4786) are denied.
ALT A slide detailing actions for administrators to mitigate Simple Network Management Protocol (SNMP) issues. It includes the following points: utilize SNMPv3 with authPriv for security, ensure administrative credentials are properly configured with different passwords for authentication and encryption, limit object identifiers to a predefined list, apply Extended Access Control Lists (ACLs) to mitigate unauthorized access, and segregate SNMP traffic to a separate management network.
