Firewall Spyware Detector
What is firewall and how does it block a program?
Firewall software is one of the must-have applications to protect the PC and the network it is connected to. Computers are susceptible virus attacks while using Internet. Harmful spyware, worms, Trojans are made by hackers to install in the users’ computers to corrupt or delete system file or steam data from the Internet. Therefore, you can install firewall software if you need to safeguard your PC with antivirus, antispyware and antimalware software. The purposes of using software firewall are:
- Protection against intruders
- Inspecting coming and outgoing connection
- Protection for private data
Protection against intruders
Firewall software provides protection against intruder files to attack computers by safeguarding either the computer or the network from the harmful traffic. The firewall has been proven to be a significant defense to protect computers and the connecting network from malicious hackers who send Trojans to access private data. It is also a must have for PCs that are connected to and accessible through several devices or through Internet.
Inspecting coming and outgoing connection
The main purpose of using firewall software is inspecting the incoming and outgoing connection. Users can either allow or block the flow of incoming or outgoing connection based on its inspection. Most of the firewall software can be configured to help users filter connection and block probable attacks on particular ports or application or service. The software blocks a connection or a computer when it detects malicious port scan activity and other types of attacks such as Denial of Service attacks, IP flooding, IP spoofing, duplicate IP addresses. It also safeguards computers and connections from other vulnerabilities that were known to be attacked often by hackers and other type of attacks.
Protection for private data
An advanced firewall software will provide additional protection that includes protect the firewall software itself from malware. If firewall software fails to safeguard the software itself, the computer and the network will be at the risk of IP address being spoofed or the information on the hard drive to be intruded or the computer can be infected. It also ensures that the web protection and privacy of data will be only accessed by a trusted network. Some firewall support filtering feature that allow only particular websites or set of IPs.
