[asterisk-dev] Introduction to ASA - the Asterisk Security Architecture

[Matt Riddell]

One of the other ways to do high load security checking is to separate
out the code into two pieces.

One that runs inline and stops/blocks parts (including defined
rejections) and another that just processes info on high rates and sends
info back to the main process to tell it what to block.

That way you can analyse data at a higher rate than would be possible
without actively causing yourself to fall to a DoS, albeit with a slight
lag in the amount of time it takes to block it.
