Auditing Logs

This section describes in detail the recording feature that collects and records information on any changes in the security appliance configuration. To access this feature, navigate to MONITOR | Logs > Auditing Logs in the SonicOS web management interface.

What is Configuration Auditing

Configuration auditing is a feature that automatically records any configuration changes that an administrator attempts from one of the available user interfaces, web management (via HTTP and HTTPS), command line (via console or SSH), or SonicWall GMS. A configuration auditing records table is created to record all attempted configuration changes, both successful and failed. With configuration auditing, SonicOS archives the history of its configuration changes, so that the administrator or others can later revisit and analyze the records. This feature is enabled by default for the platforms where it is available.

Benefits of Configuration Auditing

Auditing of configuration change records can be useful as described below:

Automatic documentation of any configuration changes performed by an administrator
Assistance in troubleshooting unexpected changes in run-time system behavior
Visibility, continuity, and consistency where there are several administrators, either simultaneously or consecutively. Each administrator has access to a record of changes performed or attempted by all other administrators.
Third party integration with Firewall Manager, SEIM systems, logging and reporting solutions
Compliance with regulations such as SOX, FISMA, NIST, DISA STIP

What Information is Recorded

Configuration auditing generates a record for every configuration change. The record includes:

Which parameter was changed
When the change was made
Who made the change
From where the change was made
Details of the change, such as the previous and subsequent values

What Information is Not Recorded

The following are not included in the Configuration Auditing operation:

Importing a Settings File - Configuration changes due to importing a settings file are currently not recorded by the configuration auditing feature. Since all current settings are cleared prior to applying imported configurations, the assumption is that all existing configurations are modified.
WXA configuration settings — SonicOS does not audit any configuration changes in WAN Acceleration. Some settings are saved on the WXA instead of the firewall, although the settings can be configured from the SonicOS web management interface.
ZEBOS settings for BGP/OSPF/RIP routing configurations — SonicOS stores these settings as one long string of ZEBOS CLI commands. Records of changes made by these commands are not duplicated in the configuration auditing operation.
Anti-Spam Junk Store applications — Configuration settings changed through a proxy server running a junk store are excluded from configuration auditing.
Licensing - All aspects of system licensing are authenticated through MySonicWall, and are not recorded through configuration auditing.
Uploading a file from Home > Capture ATP does not audit uploading a file from the page, because the contents of this page do not reside on the firewall.

Audit Recording in High Availability Configurations

The Configuration Auditing operation records changes individually for each device. It does not synchronize the recorded information between appliances in an HA pair. When the active HA unit next synchronizes with the standby HA unit, it sends configuration changes to the standby unit. The synchronization operation information updates the auditing record of the standby device in the pair. On the standby unit, the auditing record indicates that the configuration changes it recorded came from the active unit.

Modifying and Supplementing Configuration Auditing

Configuration Auditing operations can be modified and supplemented through the following:

SNMP Trap Control

SNMP (Simple Network Management Protocol) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks. SNMP traps allow the user to monitor security appliance status and configuration through a Management Information Database (MIB). Configuration auditing works in conjunction with SNMP by giving the user the option to enable a trap for each logged event collected during a network configuration change, whether successful or failed.

E-CLI Commands

E-CLI (Enterprise Command Line Interface) commands are available for configuration auditing record setting and display, for those administrators who like to work from the command line. You can use the following E-CLI commands to enable or disable configuration auditing and to view records:

to work with settings:

config(C0EAE49CE84C)# log audit settings

(config-audit)# enable

(config-audit)# debug

(config-audit)# auditall

(config-audit)# commit

to show audit records:

(config-audit)# show log audit view

Auditing Record Storage and Persistence

Configuration auditing records are saved to non-volatile storage (such as flash), so that records can be restored, if required, after a reboot. The number of records saved is directly proportional to the capability of the device, as defined in the product matrix below. Higher-end platforms can store more records than lower-end devices. Devices with no flash or smaller flash capacity do not support configuration auditing.

All configuration auditing records, on any platform, are deleted when the appliance is rebooted with factory defaults.
