Is My Firewall Working Properly?

To prevent unintended intrusion from the network and internet by using a network firewall is basically very effective. By utilizing the list of blocked IP’s, applications, and data packets, break-in attempts will be prevented to over 80% of the time. However, this applies to only some situations.

When is a firewall effective?

Firewalls are different in settings for each unique environment in a network. It depends on the behavior of the data exchange between the users and the network or internet that is permitted by the administrator. I think this is the basic conditions a firewall should be installed upon, so as not to set the firewall to a “default-allow” rule, which will practically make the firewall useless.

To make the best of a firewall, it should be set to the “default-deny” rule, with exceptions for a list of IP’s, applications, access types and confirmations, only to the widest range that the company would really need in network and internet access. It’s best to apply the “default-deny” rule with exceptions that’s based only on a daily needs of the users of the network, although a dedicated technical support that’s responsible for intelligent-”allow-rule”-supervision should be available.

This setting may be the best security firewall system setting besides antivirus implementation.

Uh uh. No Good. It’s not working. Why?

It’s relieving to know that we’re really protected. It’s only that not every network owners really dedicate their small portion of investment to the “default-deny” set of rules implementation, because they refuse to have to add additional exceptions in the future upon someone complaining that he can’t use some internet resources.

They even don’t like more on the necessity of having to add exceptions each and every day. what they’re looking for is a practical procedure, without any later intervention needed to make it work.

This matter is not there because the system administrator has no idea regarding the case, but mostly because it is a common practice. Marketing and commercials sales pitch that don’t want their products to feel hard to be used effectively also takes the part.

How can we make it better on our own system?

To get number one firewall software installed is just cool. It’s just that it’s not only that. It needs us to have at least a bit more understanding about firewalls, networks, and how they work.

None that I can remember of all vendors is providing that yet, because that is our part as users. A little priming is very important as soon as it is installed.

We can make use of a free firewall, Zone Alarm Free, install and prime it for the best. By watching the video guide, even begginers can use a firewall like a wizard.

When we take care of things nicely, and the firewall is effective, we only have to relax and enjoy the day. After all, you have worked on it and you deserve it, right?

Please do this one!

If we are to achieve something, in this case a security for our network, we need to ACT. So, what’s holding you back? Let’s do it, and relax when you have a secure networking and internet!
