My daughters 17 year old boyfriend hacked around "Nukenabber", "NetBus detective" "BO Detect" and "Cleaner" in under two days, just for fun. He's impressed with ZoneAlarm as he hasn't got through it in six weeks. Most teenagers can hack any un-protected PC by the time they are 14. It isn't long before they can get around simple protection. A firewall that screens the PC from internet scanning makes the PC 'invisible' and so less susceptible to hacking. Entry attempts are logged as they try to transit any of the PCs ports. ZoneAlarm users who are recording a lot of access hits probably have trojans (or spy-software embedded in free-ware downloads) on board transmitting to their base through the firewall by permission granted to the host program. Their base station is then aware of the internet connection, it's address and the port in use. The biggest risk to ALL PCs is invasion via ICQ chat, when other participants can pass through the firewall to plant a trojan. ZoneAlarm blocks access during subsequent sessions but the door is open during the current session. I'm impressed with ZoneAlarm and so far have seen no ill effects.
