  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)

  48  * exclusively user space. 1300-2099 is kernel --> user space
