Re: Think layers of security is all that? Think again

The thread title reminded me of this recent thread
»how to ensure PDF file viewing does not "call home"....
where firewall rules were often mentioned as a cure/fix.

Firewall rules will often prevent a call home function but it's not guaranteed.
It's just a layer.
The only way to guarantee that won't happen is to physically disconnect from the net.
Disconnecting doesn't necessarily mean a call home won't occur on reconnection but it can & should be considered as a legit security layer.

Definitely.
The cable modem to my iMac sits within arm's reach. Whenever installing or using a new or unfamiliar program, or am going to be in read-only mode for a while, I simply disconnect the ethernet wire. Been doing this for years.
