On firefox you can use LiveHTTPHeaders extension to capture all the
HTTP trafick on a readable way. Very usefull to analize & debug AJAX.
For other browser you can always use a cheapo proxy and activate all
the logging. As example SpoonProxy able that. So you can capture
everything the browser send or receive.
If the browser is embeded on other program, you have not acces to
proxy configurations, theres network tools like Ethereal to capture
trafick.
With ajax you always have the client side code, and communication
samples, only the server side code is unknom on non-FOSS software.

About the original subject. Imho, yes. A ajax call need to validate
the call, as a normal web page do. On PHP you can track a $_SESSION
var, and takes 1 line of code. Hee!, you reuse the auth method you use
on all other pages.

if (!$_SESSION["userLogued"]) {  echo 0; exit() }

A number of ajax apps will ignore or forget to add that line, and will
be posible to break into applications trough ajax.
