Discussion

Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Nonlocal maintenance and diagnostic activities are activities conducted by individuals communicating through an external network (e.g., the internet) or internal network. The Juniper SRX allows the use of SNMP to monitor or query the device in support of diagnostic information. SNMP cannot be used to make configuration changes; however, it is a valuable diagnostic tool. SNMP is disabled by default and must be enabled for use. SNMPv3 is the DOD-required version but must be configured to be used securely.

Check Content

Verify SNMP is configured for version 3.

[edit]
show snmp v3
 
If SNMPv3 is not configured for version 3 using SHA256 or higher, this is a finding.

Fix Text

Configure snmp to use version 3 with SHA256 authentication.
