Firewalls are something that I don’t talk about enough. They are the most crucial part of protecting your network, and your patient health records. Firewalls block entry into your system, and are the number one protection on your network. Let me do the best I can to describe firewalls, and why they are so important.


First off, the modem you get from your internet provider is NOT your firewall. It is a router with very basic settings that allow you to add/deny certain access. It is by no means a way to protect your data. A router may be fine for a home user, but definitely not enough for a medical practice. Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet. The job of a good solid firewall is to block unauthorized access while still permitting outward communication.

Over the years, firewalls have improved beyond simple packet filtering. They can now block threats, prevent intrusions, logging, tracking and even techniques to address evolving security threats. At this point, this type of protection is standard. If your practice does not have a firewall, you need to get one…TODAY.

Another thing a firewalls does is completely isolates your computer from the internet by inspecting each packet that comes through. The granular control is what allows this device to secure your network. Your firewall can also allow you to set up individualized virtual private networks so you can securely access your records form anywhere in the world.
