Logging and Reporting (5.6)

Logging and Reporting (5.6)

New logging and reporting features added to FortiOS 5.6.

Client and server certificates included in Application control log messages (406203)

When SSL/TLS traffic triggers an application control signature, the application control log messages now include information about the signatures used by the session. This includes the client certificate issuer, the name in the server certificate, and the server certificate issuer.

DNS Logging (401757)

FortiOS logging now includes the Detailed DNS log message type. DNS events were previously recorded as event logs. In FortiOS 5.6 DNS log messages are a new category that also includes more DNS log messages to provide additional detail about DNS activity through the FortiGate. You can enable DNS logging from the CLI using the following command (shown in this example for memory logging):

config log memory filter set dns enable end

Logging and Reporting (5.6)

DNS log messages include details of each DNS query and response. DNS log messages are recorded for all DNS traffic though the FortiGate and originated by the FortiGate.

The detailed DNS logs can be used for low-impact security investigation. Most network activity involves DNS activity of some kinds. Analyzing DNS logs can provide a lot of details about the activity on your network without using flow or proxy-based resource intensive techniques.

Added Policy Comment logging option (387865)

As an alternative to custom log fields, the functionality has been added to log a policy’s comment field in all traffic log files that use that policy, in order to sort/isolate logs effectively with larger deployments and VDOMs. The feature is disabled by default. config log setting set log policy comment [enable/disable]

FortiAnalyzer encryption option name change (399191)

For clarity, and because the default options for config log fortianalyzer setting have now changed, the option default has now been changed to high-medium in the following CLI commands:

config log fortianalyzer setting set enc-algorithm [high/high-medium/low]

config log fortinalyzer override-setting set enc-algorithm [high/high-medium/low]

config log fortiguard setting set enc-algorithm [high/high-medium/low]

config log fortiguard override-setting set enc-algorithm [high/high-medium/low]
