Module that emits CEF logs
Project description
Most Mozilla Services applications need to generate CEF logs. A CEF Log is a formatted log that can be used by ArcSight, a central application used by the infrasec team to manage application security.
The cef module provide a log_cef function that can be used to emit CEF logs:
- log_cef(message, severity, environ, config, [username,
[signature]], **kw)
Creates a CEF record, and emit it in syslog or another file.
- Args:
message: message to log
severity: integer from 0 to 10
environ: the WSGI environ object
config: configuration dict
signature: CEF signature code, defaults to ‘AuthFail’
username: user name, defaults to ‘none’
extra keywords: extra keys used in the CEF extension
Example:
>>> from cef import log_cef >>> log_cef('SecurityAlert!', 5, environ, config, ... msg='Someone has stolen my chocolate')
With environ and config provided by the web environment.
You can use the cef module with pythons logging module.
Example of logging configuration:
'syslog': { '()': cef.SysLogFormatter, 'datefmt': '%H:%M:%s', },
Send message to the log:
log_file.warning('Something', {environ: environ, username: request.user, data: data})
The SysLogFormatter will use the date format set in the log configuration (datefmt). It will convert the logging error level into a sys log error level.
CEF specific fields (version, vendor, device_version, product) can be also be provided, defaults will be used if not passed.
