A description of Windows® Firewall in Windows Vista®
Information on Windows® Firewall in Windows Vista®
Windows® Firewall is a software provided with Windows Vista® Operating System. It helps protect your computer from malicious software infecting your system and functions by restricting the resources for the software behaving in an unexpected manner. However, Windows Vista® users already have Windows® Firewall enabled in their system to protect it once Windows® start the booting up process. On adequately configuring this software, it protects your computer along with other computers in your network. The Windows® Firewall Control Panel provides an easy-to-use interface with several options available for configuration.
A few key features of Windows Vista® Firewall are mentioned below:
- Controls network traffic
- Enables program exceptions
- Security monitoring
Controls network traffic
Windows® Firewall is a device that effectively controls network traffic, wherein it blocks certain inbound traffic directed at your local network and enables the outbound traffic to flow to the Internet. Firewall lets you open Certain conduits for enabling access to the systems in your local network, like the web servers. When properly configured, Firewall remembers the required context of connections and keeps updating them. But Firewall does not invariably provide a solution to all your security problems and can lose its relevance on compromising any of the local machines.
Enables program exceptions
Firewall can create exceptions with regard to certain programs and can enable the flow of traffic. In order to enable program exceptions, ensure that the option is adequately set in the Firewall settings. There are 3 methods to enable program exception in Windows® Firewall. If you receive Windows® Firewall Security Alerts whenever Firewall blocks a program, select the “Unblock” option. This will add the program to your list of exceptions and will enable you to run the program smoothly. You can also manually add the program by selecting “Security Centre” from the “Control Panel”. Select “Windows® Firewall” in the “Windows® Security Centre” and then click on the “Exceptions” tab in the “Windows® Firewall” window. Proceed by adding the programs for which you require free incomings. If you are unable to exempt a program from Firewall by the above methods, you can also make use of the program port number. Here, determine the Process ID (PID) by typing “tasklist’ in Command Prompt. Identify the port number using the PID. Then add the program name and port number to the list of exceptions in the Windows® Firewall window.
The Security Monitoring feature allows you to create new rules along with modifying the existing ones. You could create rules to block connections and also enable connections from certain programs or ports. In addition, you can also alter the existing pre-configured rules to secure your system from unwanted software attack. The New Rule Wizard lets you create new rules using the Security Monitoring feature. You can also opt for exporting your list of rules to another text file.
