All,
Any service you recommend for doing domain classification and lookups against my Squid proxy logs? Just general classification and of course alerts for malware.
The best way to answer this kind of question in general (and perhaps in specific for your case) is to use the Splunk Security Essentials
app because it allows you to breakdown content by types of data (sources/sourcetypes) available:
