Would you apply the same thinking to *outbound* traffic by first denying
all outbound traffic, and then adding rules for, say eBay, Slashdot,
etc?

While real time firewall blocking of inbound threats reaches exhaustion
fast, I think a real time block of threats that you might accidentally
connect to outbound (like phishing sites or botnet C&Cs) does indeed
make sense as a) the volume is typically lower, and b) you usually
restrict outbound traffic only by port/service . What are your thoughts
on that?

Cheers,
Frank
