About Personal Firewalls
The Trend Micro PC-cillin 2002 Personal Firewall protects your computer against attacks from the Internet. A firewall creates a barrier between your computer and the network (LAN, Internet). This barrier examines and filters network traffic to your computer. By filtering network traffic, the firewall prevents malicious programs or files from entering your computer.
With the PC-cillin 2002 Personal Firewall, you can also control the security level, create a list of sites you know can be trusted, and view a list of blocked ports. The Personal Firewall is actually composed of the following components:
-
Cloaking: Prevents your computer from being found. Cloaking hides the entry points (ports) of your computer making it appear to be disconnected from a network. Hackers using techniques like NetBIOS browsing, port scanning, or ICMP packet special processing will be unable to locate your computer.
-
Firewall: Provides a barrier between your computer and the network (LAN, Internet). This barrier examines and filters network traffic coming into your computer. By filtering network traffic, the firewall prevents malicious programs or files from entering your computer. The firewall protects against attacks hackers commonly use including: Ping of Death, IP conflict, SYN flooding, and others.
-
Trojan Backdoor Blocking: If a hacker has already broken into your system, he or she could have installed a Trojan (small hidden program) onto your computer (unlike viruses, Trojans do not replicate themselves, but can still wreak havoc on your system). To avoid being traced, the hacker can then use your computer to attack other computers. The Trojan Backdoor Blocking function prevents hackers from using your computer by blocking Back Orifice, Back Orifice 2000, Net Bus, Deep Throat and other known back door programs.
There is also an Internet Emergency Lock feature that lets you immediately disable all Internet activity if you suspect you are under attack. Enabling this feature immediately stops all traffic to and from the Internet.
