If SNMP is enabled, the Juniper SRX Services Gateway must use and securely configure SNMPv3.
Vulnerability discussion
To prevent non-secure protocol communications with the organization's local SNMPv3 services, the SNMP client on the Juniper SRX must be configured for proper identification and strong cryptographically-based protocol for authentication.SNMPv3 defines a user-based security model (USM), and a view-based access control model (VACM). SNMPv3 USM provides data integrity, data origin authentication, message replay protection, and protection against disclosure of the message payload. SNMPv3 VACM provides access control to determine whether a specific type of access (read or write) to the management information is allowed.The Junos operating system allows the use of SNMPv3 to monitor or query the device for management purposes. Junos does not allow SNMPv3, of any type, to be used to make configuration changes to the device. SNMPv3 is disabled by default and must be enabled for use. SNMPv3 is the DoD-preferred method for monitoring the device securely. If SNMPv3 is not being used, it must be disabled. The following commands will configure SNMPv3. The Junos operating system allows the use of FIPS approved protocols for both authentication (SHA1) and for privacy (AES128). These protocols should be used to ensure secure management connections.
Check content
Verify SNMPv3 is enabled and configured.
[edit]
show snmp
If an SNMP stanza does not exist, this is not a finding.
If SNMPv3 is not configured to meet DoD requirements, this is a finding.
If versions earlier than SNMPv3 are enabled, this is a finding.
Fix text
Enable and configure SNMPv3 and configure a trap and community string.

Pro Tips
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
text/turtle or
Accept: application/rdf+xml.
