Cause And Disadvantages Of Firewalls

Not many people know or are aware of what a firewall is or how it works. Firewalls are installed onto your computer system as a security system that is making sure that nothing such as a virus gets into your computer, it also controls the incoming and outgoing network traffic based on how the person set the settings. Firewalls were first used in the 1980’s it was called a packet filter before actually called a firewall. Firewalls are meant to be installed on your computer so that your computer won’t be hacked. A firewall is the most common security system used in any type of computer. Many people think that a firewall is something simple that once it is installed and applied, then it will work perfectly fine, but in reality a firewall should

Firewalls are not effective enough to protect devices because people can easily hack and are getting passed firewalls therefore there should be something other than firewalls to protect devices. There are many factors on why a firewall is not an effective way to protect personal information. Every year there are new and more advanced technology being made and used, and firewalls are not up to date or are missing many factors that will not keep up with these new and more advanced technologies which make it so much easier for people to get passed a firewall. For example, in Kyle Cebull’s article “3 Reasons your Business Firewall or Router Isn't Effective Against Threats” he gives an example from the computer company Dell which says, “According to Dell, by the end of 2016, more than two-thirds of all internet traffic will be encrypted. Even some network administrators don’t realize that viruses and malware are riding into their network via encryption” (Cebull). What

But with evidence that shows that even banks, which need big and well prepared security systems cannot handle hackers, then a firewall alone should not be used as a way to protect a device. But if they use something to help support the firewall, it can potentially help stop all these cyber attacks happening and could help the firewall perform better. For example in the article “Two-Factor Authentication (2FA)” it explains what a two-factor authentication is and how it is a good way to secure your personal information. The two factor authentication has been used in big companies such as Instagram, Apple and Facebook. It is such a simple thing to use and a very hard thing to get passed by. A two factor authentication works as a second layer of security which can be seen as a support for a firewall, if a hacker wants to do something they might be able to get passed the firewall, but then they will have to get passed the two factor authentication and it is harder to get passed this because once they try to get passed it the owner of the account or the device will be alerted because it will tell the them that your device or account is trying to be logged in somewhere (“Two-Factor Authentication”). The two factor authentication also will need to have a code put in to be able to access whatever the person wants to access
