  30 * 1000 - 1099 are for commanding the audit system
  31 * 1100 - 1199 user space trusted application messages
  32 * 1200 - 1299 messages internal to the audit daemon
  33 * 1300 - 1399 audit event messages
  34 * 1400 - 1499 SE Linux use
  35 * 1500 - 1599 kernel LSPP events
  36 * 1600 - 1699 kernel crypto events
  37 * 1700 - 1799 kernel anomaly records
  38 * 1800 - 1999 future kernel use (maybe integrity labels and related events)
  39 * 2000 is for otherwise unclassified kernel audit messages (legacy)
  40 * 2001 - 2099 unused (kernel)
  41 * 2100 - 2199 user space anomaly records
  42 * 2200 - 2299 user space actions taken in response to anomalies
  43 * 2300 - 2399 user space generated LSPP events
  44 * 2400 - 2499 user space crypto events
  45 * 2500 - 2999 future user space (maybe integrity labels and related events)
  46 *
  47 * Messages from 1000-1199 are bi-directional. 1200-1299 & 2100 - 2999 are
  48 * exclusively user space. 1300-2099 is kernel --> user space 
  49 * communication.
