  • 1.  SWG SSL Filtering ( inline+Proxy)

    Posted Mar 27, 2014 10:21 AM

    Hello all. I am deploying Virtual SWG in my envoirement and I need to implement the following functionality.

    I need to filter some HTTPS URLs not the whole domain via SSL deep inspection through inline + proxy mode in the virtual envoirement. for example if I want to filter some specific URLs within youtube ( not the whole website)  which is using HTTPS how can this be achieved in this mode ? How to display blocked pages for HTTPS website sfor users ?

    what policies do I need to configure ? Secondly in inline + proxy mode do i need to configure my inline IP address within User's browsers ? or will it be transparent for the users ?

    What mechanism does SWG use for decrypting the SSL traffic from the users ? does it download certificates of the webistes from internet which users are accessing ?

    Regards,

    Sooooo, in order to block specific parts of a SSL encrypted site, you must be using SSL Deep Insepction.  More info on SSL Deep Inspection can be found below (with further useful links inside this article):

    http://www.symantec.com/docs/HOWTO54180

    Essentially though (in bullet points):

    • SWG must in proxy mode
    • Enable SSL Deep Inspection
    • Download SWG's cert and distribute to clients
    • Configure clients to use SWG's LAN/WAN IP address and ports (for https and http respectively) as proxy via GPO/PAC/WPAD/whatever
    • Configure SWG Policy for SSL Deep Inspection Inteception
    • Configure SWG Policy for filtering (with a lower priority)

    As far as blocking pages go, the below articles are quite handy:
    http://www.symantec.com/docs/TECH175244
    http://www.symantec.com/docs/TECH206412

    And to answer your final question, the whole SSL Deep Inspection process works in a man-in-the-middle scenario.  Clients create a SSL connection to the SWG, the SWG creates a SSL connection to the external website.
