MicroData believes that every business should have a proper firewall plan to protect its valuable data assets from any malware that could be threatening to the data. Moreover, firewall makes sure to close off any potential doors for hackers to step in and make sure they do not have any control over any of your network traffic. A firewall is a program that scans all network traffic for particular sorts of activities (e.g., sending e-mail messages or looking up Web sites). When it detects an unlawful action, it disables access to the relevant port until the user or administrator fixes the problem. When you use an Internet browser (such as Microsoft Explorer) to connect to a Web site, the firewall may prevent you from accessing the site until you enter a valid login and password. Installing a firewall on your system is advantageous for a variety of reasons: It protects against viruses and malware, prevents users from exchanging files unlawfully over networks, keeps away unwanted software programs like as chat rooms, and prohibits people from visiting restricted sections of your network without authorization (i.e., “sniffing” packets).
