blocking youtube

[jack samuel]

Dears,

I m blocking a streaming media category in url filtering but it is not getting blocked, and it is falling in the default action,  I have a question that without enabling SSL decryption https websites cannot be blocked ??  as I have seen in forums people says that it can be controlled by application filtering??? is it correct

I want to block  many https sites so how we can controlled all https sites  becz enabling ssl decryption for all the traffic will impact the performance on the firepower module on 5525X

thanks

Which version are you running? There has been an issue with 6.1 that resulted in categories not working correctly for url filtering. Check your connection events. What is the URL Category for the specific connection event?

URL Filtering only works to a certain degree with SSL since the payload cannot be checked for the URL and only the CN / DNS entry can be used to filter traffic.
