Vulnerability discussion

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded.Since the A10 Networks ADC can monitor connectivity to servers, it can be configured to perform a health check of the Syslog servers. When connectivity is lost or the health check fails for another reason, it can send an SNMP trap notifying authorized personnel.

Check content

Review the device configuration. The following command shows the configured Server Load Balancing instances: show run | sec slb If no Server Load Balancing instance is configured with a health check to the Syslog server, this is a finding. The following command shows the device configuration and filters the output on the string "snmp": show run | inc snmp This will include which SNMP traps the device is configured to send. If the output does not include "snmp-server enable traps slb server-down", this is a finding.

Fix text

The following command enables the device to send an SNMP trap when the health monitor shows the connection to the server is down: snmp-server enable traps slb server-down The following command enables the device to send an SNMP trap when the health-monitor shows the connection to the server is up: snmp enable traps slb server-up The following command creates a health monitor for UDP 514 (the Syslog port): health monitor [monitor name] method udp port 514 The following command creates a Server Load Balancing instance and assigns a health monitor to it: slb server server-name [ipaddr | hostname] health-check [monitor]

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.
