Students, using HTTPS now on Proxies

[djbisbey]

Hi,

we have banned the http-proxy in school to stop them downloading and accessing sites they shouldn't, however they have now found using https based proxies bypasses this.

What is my next possible solution in my ever on going war with students.

Any advice / help much appreciated.

Thanks in advance.

OK.

Looking at the URL categorisation for this site in brightcloud it comes up in the "proxy Avoid and Anonymizers" category - so the simplest solution would be to apply a URL filter profile which blockas this category in its entirety (deny) and apply that profil to your outbound interface.

Because it's an atempted SSL connection, the users will get no nice "Access denied" banner because the PA can't do that for HTTPS connections - but it should block them anyway owing to the database categorisation.

Of course, if you don't have a valid web filter license you mgiht be in trouble. 🙂 I'm not sure if you can still create custom URL filter cetagories without the "general" web filter license, but you could try that also - create a custom URL filter category, add your proxy site to it, set it in a URL filter profile for "deny" with everything else allowed.

Or you could, as suggested, so SSL decrypt and stop them that way.

Cheers.

Can you share how you set up the SSL Decryption with another school district tech having the same issue? I'm not having any luck. Thanks!

There is a bug with application filtering, it doesn't seem to work on OS 3.1.5 or 3.1.6, not sure about previous version.  I logged a ticket with PaloAlto but looks like the bug is not important so it won't be fixed until release 4.

Hi tontabill,

I am sure if you work with your local sales team on the issue prioritisation they will help you.

Best Regards

I just got into the PA this past year. Would you mind sharing how you set up the SSL Decryption with our school?

For the safety of data transportation, experts advise students to use the HTTPS protocol, because any information entered using SSL is encrypted, so in case of interception, the attacker receives a random set of characters and can download your dissertation.
