Audit log configuration When managing SANs you may want to filter or audit certain classes of events to ensure that you can view and generate an audit log for what is happening on a switch, particularly for security-related event changes. These events include login failures, zone configuration changes, firmware downloads, and other configuration changes-in other words-critical changes that have a serious effect on the operation and security of the switch. Important information related to event classes is also tracked and made available. For example, you can track changes from an external source by the user name, IP address, or type of management interface used to access the switch. Auditable events are generated by the switch and streamed to an external host through a configured system message log daemon (syslog). You specify a filter on the output to select the event classes that are sent through the system message log. The filtered events are streamed chronologically and sent to the system message log on an external host in the specified audit message format. This ensures that they can be easily distinguished from other system message log events that occur in the network. Then, at some regular interval of your choosing, you can review the audit events to look for unexpected changes. Before you configure audit event logging, familiarize yourself with the following audit event log behaviors and limitations: • By default, all event classes are configured for audit; to create an audit event log for specific events, you must explicitly set a filter with the class operand and then enable it. • Audited events are generated specific to a switch and have no negative impact on performance. • The last 256 events are persistently stored on the switch and are streamed to a system message log. • The audit log depends on the system message log facility and IP network to send messages from the switch to a remote host. Because the audit event log configuration has no control over these facilities, audit events can be lost if the system message log and IP network facilities fail. 46 Fabric OS Administrator's Guide 53-1001336-01

Audit log configuration
When managing SANs you may want to filter or audit certain classes of events to ensure that you
can view and generate an audit log for what is happening on a switch, particularly for
security-related event changes. These events include login failures, zone configuration changes,
firmware downloads, and other configuration changes—in other words—critical changes that have a
serious effect on the operation and security of the switch.
Important information related to event classes is also tracked and made available. For example,
you can track changes from an external source by the user name, IP address, or type of
management interface used to access the switch.
Auditable events are generated by the switch and streamed to an external host through a
configured system message log daemon (syslog). You specify a filter on the output to select the
event classes that are sent through the system message log. The filtered events are streamed
chronologically and sent to the system message log on an external host in the specified audit
message format. This ensures that they can be easily distinguished from other system message log
events that occur in the network. Then, at some regular interval of your choosing, you can review
the audit events to look for unexpected changes.
Before you configure audit event logging, familiarize yourself with the following audit event log
behaviors and limitations:
By default,
all
event classes
are configured for audit; to create an audit event log
for specific
events
, you must explicitly set a filter with the
class
operand and then enable it.
Audited events are generated specific to a switch and have no negative impact on
performance.
The last 256 events are persistently stored on the switch and are streamed to a system
message log.
The audit log depends on the system message log facility and IP network to send messages
from the switch to a remote host. Because the audit event log configuration has no control
over these facilities, audit events can be lost if the system message log and IP network
facilities fail.
