Internal Firewall Best Practices


Network Firewall Security

A firewall is a shield for a computer which prevents unauthorized access to or from a private network. It works on particular security protocols. If a specific program doesn't meet those protocols, then it doesn't allow them to access the internet. This system prevents unauthorized users from accessing private networks connected to the internet. Every message and data are entering or leaving the network pass through the Firewall. It examines all messages and blocks them, which doesn't meet specific security criteria. You can use wireless in either software or hardware form. For optimal security, you can use a combination of both. For the different level of network security, there are various kinds of firewalls, such as:

  • Web application firewalls
  • Proxy Server Firewalls
  • Circuit-level gateway implementation
  • Packet-filtering

Firewall Device

It is a hardware firewall which exactly likes a software firewall. The difference between hardware and software versions of the Windows firewall is that the former lives outside of the server. This device also filters the traffic to a computer and protects it from harmful virus attacks. Just like a standard computer, a firewall device has a processor, memory, and sophisticated software. They make the most from powerful hard and software networking components. All the traffic is thoroughly checked against configurable ruleset. Based on inspection, Firewall hardware grant or deny access.


Window Firewall Log

During the internet traffic filtration process, almost every kind of fireward keeps a log. It’s a document that shows you how your Firewall is dealing with different types of traffic. You can quickly get valuable information from this log, such as source, port numbers, protocols, and destination IP addresses. Here is how the Windows Firewall log file proves useful.

You can check:

  • whether your Firewall is working correctly or not.
  • Any suspicious activity
  • Whether there is some repeated failed access attempt from a specific IP. If that happens, then you can take necessary security measures to deal with that particular ID.
  • The cause of application failure is a Windows firewall or something else.

By default, a log file is disabled, but you can enable it.
