 32 * 1000 - 1099 are for commanding the audit system
 33 * 1100 - 1199 user space trusted application messages
 34 * 1200 - 1299 messages internal to the audit daemon
 35 * 1300 - 1399 audit event messages
 36 * 1400 - 1499 access control messages
 37 * 1500 - 1599 kernel LSPP events
 38 * 1600 - 1699 kernel crypto events
 39 * 1700 - 1799 kernel anomaly records
 40 * 1800 - 1899 kernel integrity events
 41 * 1900 - 1999 future kernel use
 42 * 2000 is for otherwise unclassified kernel audit messages (legacy)
 43 * 2001 - 2099 unused (kernel)
 44 * 2100 - 2199 user space anomaly records
 45 * 2200 - 2299 user space actions taken in response to anomalies
 46 * 2300 - 2399 user space generated LSPP events
 47 * 2400 - 2499 user space crypto events
 48 * 2500 - 2999 future user space (maybe integrity labels and related events)

 50 * Messages from 1000-1199 are bi-directional. 1200-1299 & 2100 - 2999 are
 51 * exclusively user space. 1300-2099 is kernel --> user space
