cef_to_syslog

High performing parser to convert cef strings to json. Supports both CEF:0 and CEF:1 versions.

Sample Usage:

const cef = require('cef_to_json')
console.log(cef.toJson(
'CEF:0|Security|threatmanager2|1.0|100|worm successfully stopped|10|src=10.0.0.1 dst=2.1.2.2 spt=1232'));

Sample Output:

{
  cefVersion: '0',
  deviceVendor: 'Security',
  deviceProduct: 'threatmanager2',
  deviceVersion: '1.0',
  deviceEventClassId: '100',
  name: 'worm successfully stopped',
  agentSeverity: '10',
  src: '10.0.0.1',
  dst: '2.1.2.2',
  spt: '1232'
}
