Firewall software regulates incoming and outgoing data between different security domains in order to block unauthorized users from accessing your computer or your data while permitting approved communications. It is an effective means of establishing and maintaining computer security without limiting functionality.
Features and Advantages of Firewall Software
Desktop firewall software typically provides data filtering, port monitoring, registry protection, email and file protection, and safeguards to make your personal information inaccessible to anyone but you. It also shares some security features with network software in that it provides network monitoring capabilities. This feature is standard on business firewall software, as businesses typically set up local area networks (LANs) to streamline inter-office communications between users.
Firewall software also provides hacker detection tools, password setup and management capabilities, and a wide range of settings and restrictions that allow you to do everything from blocking popup windows to disallowing Web traffic from predefined sources.
Antivirus and firewall software can be combined for enhanced protection. Antivirus software is used to find and delete viruses, worms and other malware threats. Because antivirus firewall software provides superior protection, it is often favored for network security applications, though it can slow down your computer noticeably.
Firewall software prevents hackers and unauthorized users from accessing, manipulating, stealing or otherwise compromising your data. It is a vital protective measure for businesses to take.
Popular Firewall Programs
Popular personal firewall software applications include ZoneAlarm Pro, Outpost Firewall Pro, Normal Personal Firewall, eConceal Pro, Webroot Desktop Software and Injoy Firewall. In most cases, the companies that produce these applications also offer similar programs designed to meet the needs of businesses who have in-office computer networking setups.
If you want to evaluate the quality or effectiveness of a particular program, there are five key functionality categories to consider. First, compare your needs against the program’s set of features. Keep searching until you find an application that delivers everything you’re looking for. Second, ease of use is a major concern—a firewall program isn’t any good unless all the users in your network know how to use it properly. Reliability is the third key issue—look for evidence that the firewall software functions at a high level over an extended period of time. Fourth, make sure the manufacturer offers extensive help and support services in the event of a malfunction or breakdown. Finally, make sure the software is easy to install—this will save you a lot of time and make sure your network is secure faster.
