A router [a] is a networking device that forwards data packets between computer networks. Routers perform the “traffic directing” functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node
Essentially, you need to have firewalls fully implemented on your site. There are three basic types of firewalls: hardware firewalls, software firewalls, and web application firewalls (WAFs). Typically, an infrastructure has a combination of hardware and software firewalls, along with ones specifically designed for web applications, because apps create their own unique challenges and have become such a frequent target for intrusions. Making sure that technology is system-wide is one of the HIPAA compliant server requirements.
What is a firewall?
Firewall is actually a kind of broad term. It refers to a hardware or software system (i.e., physical component or an app) that is used to secure a network, via a set of rules that control the traffic that’s entering and exiting it.
The hardware/software distinction is just one way to categorize firewalls, though. As indicated in the US Department of Commerce’s NIST firewall guidelines (Special Publication 800-41), and as expanded by TechTarget, five primary types of firewalls are application-level gateways (proxies), circuit-level gateways, multilayer inspection firewalls, packet-filtering firewalls, and stateful inspection firewalls.
