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.
