What Is a Firewall?
A firewall is a network security tool that prevents unauthorized users and hackers from accessing a network. Antivirus software protects data from infection; firewalls deter attackers by preventing them from gaining access to your computer in the first place.
Here are some of the top reasons why network firewall security is so crucial for enterprises in the 21st century:
A Firewall Protects Your Company From Hackers
Social engineering is the most common way hackers get into business systems and steal information. They use a variety of tricks to deceive employees who don’t know what’s going on into giving them private and sensitive information.
The best way to stop this problem from getting worse is to get good cybersecurity training, but firewalls also help significantly. Firewalls can tell you when bad traffic is coming in and stop attacks. You can buy a firewall that’s only hardware, or a firewall that’s both hardware and software. But it’s strongly recommended you buy a firewall that protects against viruses.
A Firewall Enables Blocking of Unapproved Websites
Firewalls stop people who shouldn’t be on your network from getting in; however, you can also stop your users from going to certain websites. This is helpful if you don’t want your employees to go to inappropriate websites or sites which might have harmful downloads while working on your network.
For instance, you might not let your employees go to pornographic sites, or sites where they can gamble. You can also block access to shady online shopping sites, or sites which let you download things illegally.
A Firewall Safeguards Your Company From Malicious Code
Firewalls keep viruses and other bad software from getting into computers. They watch the data coming in and going out and record any strange things. They can be set up to let you know when there is an attack, or when someone tries to get into your computer system without your permission. These alerts can make a big difference in how secure your business is.
Repeated alerts could signal that a threat is watching your organization and that you need to beef up your defenses. At this point, you need to start making a good plan for what to do if you do get attacked.
A Firewall Lets You Limit Bandwidth Usage
Firewalls can be used to limit the amount of traffic on a network. With a firewall, you can limit the quantity of bandwidth that various types of data use. One way to do this is to limit the bandwidth used to stream video and other media files.
A firewall can be set up so that only certain kinds of traffic can connect to the internet. For example, you might want to stop people from getting to certain websites, but still let them use your office printer.
A Firewall Provides VPN Services
A VPN uses encryption to ensure that two people can talk to each other safely. The encrypted traffic moves through public networks like the internet without anyone knowing.
A firewall can provide VPN services. For example, you can set up your firewall so that only a certain number of computers can connect to the internet. Then, you can make a tunnel that lets these computers talk to each other over the internet.
You can also use a firewall to send encrypted data between your business computers and your remote office; this can also link your company’s local area network (LAN) to a wide area network (WAN).
