Geek Speak: Can I secure Application Level Tracing?
One of my co-workers( Glen Gordon) found a good article, @ https://scottcate.mykb.com/Article_D5C6F.aspx
Bottom line: secure the trace.axd file with an entry in web.config. J
<location path="trace.axd">
<system.web>
<authorization>
<allow users="admin" />
<deny users="*" />
</authorization>
</system.web>
</location>
