  1. In this world of information technology where everything is being done over the Internet, Flash Web Designers companies and people really need to ensure that they are protected from malicious attacks whether it is stealing valuable information or spreading computer viruses. The single most important and effective weapon that you can use to keep your personal information as well as your customer's is to use a firewall.

    In fact, today firewalls are being used by nearly every online person or company and in the case of companies; certain rules are created that help in controlling the intranet Web connectivity. Basically, a firewall will give you or a company the right to decide how users on the network can access information that is being passed between the Web and other concerned servers.

    Furthermore, firewalls have their own means of controlling how traffic enters and leaves the network and the easiest way in which they achieve this is by using what is known as filtering of packets. Thus, the firewall has to analyze packets of data and compare this data with predetermined filtering instructions. If the filter passes the packet of data then the data becomes available to you and other users; otherwise it will remove the information.

    There is also an alternative means employed by firewalls in protecting you and this method is known as proxy service. In fact, yet another effective means employed by firewalls to protect you and sensitive information is through comparing certain pieces of data packets against information retrieved from sites that are considered as being trusted. Thus, in case the information being passed through the firewall does not contain the required characteristics, it will be considered harmful and so, protected and even blocked from entering your system.

    In the end, the kind of firewall that you choose to use depends on a number of things such as your own personal preference, the importance of the data that you are handling and also the level of security that you desire. Furthermore, it is also possible to make the firewall conform to your particular needs and thus you can customize it so that only information that you consider safe is passed through the firewall and anything that is of a critical nature, can be closely monitored and passed only when it is deemed to be safe to do so.
