Title

The Palo Alto Networks security platform must not use SNMP Versions 1 or 2. (Cat I impact)

Discussion

SNMP Versions 1 and 2 are not considered secure. Without the strong authentication and privacy that is provided by the SNMP Version 3 User-based Security Model (USM), an unauthorized user can gain access to network management information used to launch an attack against the network. SNMP Versions 1 and 2 cannot authenticate the source of a message nor can they provide encryption. Without authentication, it is possible for nonauthorized users to exercise SNMP network management functions. It is also possible for nonauthorized users to eavesdrop on management information as it passes from managed systems to the management system.

Check Content
