Firewall products prevent fraudulent intrusion into computer networks. They range from small software components to complex network devices that monitor and remove potential threats. Basic firewalls are available with antivirus protection, while advanced ones cost thousands of dollars and include individual user management controls and network monitoring. Device-based firewall products are built into network hardware devices and provide more granularity in enterprise network traffic. Advanced features include hardware redundancy and performance monitoring.
Firewall products are computer security systems that prevent fraudulent intrusion into computer networks. These products range from small software components to more complex network devices that can track, monitor, and remove potential threats on a computer network. Most of the products run on servers or desktops and provide a sophisticated tool for monitoring your computer’s network traffic.
Before purchasing any firewall product, the consumer must determine how much security is needed. Basic firewall tools are available with most antivirus protection software, but provide limited security for corporate networks. Sophisticated products can cost several thousand dollars and are typically used in large organizations.
A good firewall tool can monitor and log every message sent over the network. This provides auditing and control over content shared over a computer network. Firewall is the main tool used to prevent harmful viruses from entering a computer network.
Basic firewall products include website blocking capabilities. This allows the computer owner to block specific websites from interacting with the home computer network. It provides basic coverage and protection against potential intruders and is relatively inexpensive and easy to install.
Advanced firewall products include individual user management controls. This allows for higher security features for specific users and applications on the network. Role-based security is typically found on enterprise firewall security products and includes advanced logging and monitoring tools for each user on the network.
Several companies sell device-based firewall products. These special software components are built into network hardware devices. An appliance firewall application is typically more expensive than a software version, but provides more granularity in enterprise network traffic. It typically includes logging and monitoring capabilities that can be stored on external machines for analysis purposes.
Network monitoring and advanced reporting are attractive features on sophisticated firewall products. These tools can track intrusion patterns and instantly send appropriate alerts to security personnel. The reporting capabilities of these products provide statistics on potential intruders and pattern analysis of how they are attempting to infiltrate your organization.
Companies should look for commercial software devices that provide state-of-the-art monitoring and protection of enterprise-wide network traffic. Advanced firewall features include hardware redundancy and performance monitoring, essential for large organizations.
