Is your firewall spying on you?
Whom do we trust?
The best way of penetrating users’ PCs to see what they get up to online would be to become a Firewall maker. Like, when I wanted a Firewall and was too tight to pay for one, I turned to Checkpoint’s little freebie Zone Alarm. It sits between you and the Internet and lets you know when someone’s trying to sneak in through your backdoor or when a program you’re running tries to connect to the Web for no apparent reason. When you’re as techie as me – not very – you just have to trust it.
