Vulnerability discussion

SNMP Versions 1 and 2 are not considered secure. Without the strong authentication and privacy provided by the SNMP Version 3 User-based Security Model (USM), an attacker or other unauthorized users may gain access to detailed system management information and use the information to launch attacks against the system.

Check content

Determine if the system's SNMP service only uses SNMPv3 or its successors. Consult vendor documentation to determine if earlier versions of SNMP are supported and what configuration is necessary to enable or disable the protocols. Snmpd version 1 was the only version available in AIX versions prior to AIX 5.2. #which snmpd #ls -l If the results are not /usr/sbin/snmpdv3e or /usr/sbin/snpdv3ne this is an earlier version of the protocol used by the service, this is a finding.

Fix text

Configure the system's SNMP service to only use SNMPv3 with encryption or its successors. The SNMP version supporting encryption is an installable fileset on the expansion cd as fileset 'snmp.crypto'. Enable snmpv3 with encryption. # snmpv3_ssw -e

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.
