Granular URL Monitoring

mike406 — Mon, 06 May 2019 22:29:00 GMT

I want to be able to grab full URLs when specific sites are visited e.g. github so I can see what app/repo is being hit. Right now all I get is the domain.

How granular can URL monitoring be? Can I get a full URL from URL filtering or URL category hits?

Can I trigger a packet capture when specific URLs are hit?

@mike406,

Do you decrypt outgoing traffic?

No, not yet.

@mike406,

Then you are recording everything that the firewall can see. Without decryption you won't get the full URL, just what the firewall can see in the session handshake.

Hi @mike406 ,

As @BPry mentioned, the way firewalls will identify the base URL is by examinig the servername field in client hello. if your communication is through ssl, the communication will be encrypted after ssl handshake, so the GET messages afterwards will be encrypted, you wont ba able to see it unless you have decryption configured.

Hey @mike406

Under your URL filtering profile -> URL Filtering Settings, have you tried disabling the default option "Log container page only"?

Just tried this, but no luck. Thanks for the idea, though.
