Custom tls logging
|
||
|
|
===================
|
||
|
|
|
||
|
|
In your Suricata.yaml, find the tls-log section and edit as follows:
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
|
||
|
|
- tls-log:
|
||
|
|
enabled: yes # Log TLS connections.
|
||
|
|
filename: tls.log # File to store TLS logs.
|
||
|
|
append: yes
|
||
|
|
custom: yes # enabled the custom logging format (defined by customformat)
|
||
|
|
customformat: "%{%D-%H:%M:%S}t.%z %a:%p -> %A:%P %n %n %d %D"
|
||
|
|
|
||
|
|
And in your tls.log file you would get the following, for example:
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
