Its been there since 2.6.6 kernel. IOW - day 1.

The queueing is complicated and if you have a group of processes it gets real 
messy. The audit queue tries hard for guaranteed delivery or take the system 
down if the flow is not working right. Its not like syslog or iptables 
logging.

SE Linux helps for MLS systems, but for CAPP, it doesn't come into play. The 
data flowing through the audit system could be very sensitive. Anyone needing 
access to the stream either needs to replace auditd, write their own 
dispatcher, or write a plugin to the shipped dispatcher. This way the admin 
knows exactly what processes have access to the data.
