Manny got a Tiny Hardware Firewall, and he really likes it for when he's on the road. It was recently updated by THF and he wants to know how often he has to send it in to get updated. Leo says that security flaws have to be acted upon by getting one to click on something so the malware can take advantage of it. Often, so-called zero-day exploits are designed around this, and people have no real way of knowing they've been hacked. But keeping a system and THF patched, will mitigate vulnerability, except for zero-day exploits, which are patched pretty quickly.
