Is a Computer Firewall Really Necessary?
To prevent unintended intrusion from the network and internet by using a network firewall is basically very effective. By applying all of it’s list to block packets, programs, and IPs, a firewall will minimize infiltration to over 80% of the time. However, this applies to only some situations.
How can we tell if a firewall is effective?
Firewalls should be tuned 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 with a comprehensive built-in firewall in it.
Why is it not effective?
It’s tempting to think that we are being under protection. 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 resent more on the necessity of having to add exceptions based on a daily basis. what they’re looking for is an easy to implement procedure, without having to mess with it later to make it work.
This issue is not there because the system administrator has no idea regarding the case, but mostly because it is a common practice. Commercials and marketing advertising copy that don’t want their products to feel hard to be used effectively also takes the part.
How can we make the best out of it?
To acquire number one firewall solution installed is fine. It’s just that it’s not good enough. It needs us to have at least a bit more knowledge about networking, computer security, and network firewall.
None that I can remember of all vendors is providing that yet, because that is our part as users. A little priming is crucial after the installation is done.
I’m talking about making use of a free firewall, Zone Alarm Free, install and prime it for the best. By watching the video guide, first-time and fire-and-forget users can benefit from it.
When we take care of things nicely, and the firewall is effective, all we have to do is just relax and enjoy the day. Well, you worked hard for it that you inevitably deserve it, don’t you think?
The most important thing!
To achieve things that we want, (network computer security is one of it), the major thing to do is ACTION. Now, what are we waiting for? Let’s do it, and relax when you have a secure networking and internet!
