    Unqualified (local) DNS lookup

    I'm wondering if it's possible to configure Synology DNS to provide a default domain when an unqualified name is sent. I can't see anything in the GUI or documentation that talks about this. My old system uses dnsmasq as the DNS server, and when set with the --domain option, this will only...

    Threat Prevention "ET EXPLOIT [Possible] Apache log4j RCE Attempt" signatures added to ET OPEN

    I've started to see Threat Prevention events and alerts flagged as relating to the new Apache log4j exploit. The 20 new ET OPEN rules are defaulted to drop: If you haven't enabled rules for "Attempted Administrator Privilege Gain" then it would be sensible to enable them now.
