    I block LSASS from/to LAN and WAN access. Doing so doesn't create a problem, but I see LSASS trying to access the Internet when I launch certain apps or games or game services, like EA Games - Origin. Why would programs and/or games use it? Is it responsible for more than just local user credentials?

    Local Security Authority Subsystem Service.

    Should not be blocked from Internet, as it is also the one responsible for updating the certificate store (I had also blocked it and the cert store became outdated eventually). The games might use it to access the cert store and verify their own validity.

    Thanks for this info. I searched quite a bit to find documentation about this to no avail.
