InformationFor SNMP polling, only SNMPv3 should be used.
SNMPv3 utilizes AES-128 encryption, message integrity, user authorization, and device authentication security features. SNMPv2c does not provide these security features. If an SNMPv2c community string is intercepted or otherwise obtained, an attacker could gain read access to the firewall. Note that SNMP write access is not possible.
