Consider this to be similar to a door that they have the ability to open, or close and lock. Medical facilities can program this software, and/or hardware, and decide what comes in and what goes out, thus limiting what data is transmitted outside their internal network based on security requirements (Beal). This type of technology can help catch unencrypted files that may have been unintentionally sent to an outside source. When this occurs, it is considered a breach. Use of the firewall can help prevent unintentional breaches such as this from happening. The firewall can also be used to prevent outside computers from accessing their network. Some downsides to this technology are the cost and performance. In order to keep up with the most current trends, better, newer and more expensive equipment may be needed. This can become very costly. The firewall may also slow performance to some degree, but is well worth the benefit of the security that it
