[IT Security Tip] What is a Firewall?

When you are using the internet for your work or personal use, you are susceptible to an attack. Having a reliable firewall in place will help keep you protected. Being proactive when it comes to cyber security is key to keeping your business and employees safe.

When thinking about what a firewall is and how it works it's best to think of it as a filter. The firewall filters out all data based on settings and rules you put in place regarding what you want coming in and going out. It acts as your first line of defense against potential attacks. Firewalls can prevent malicious software from gaining accessing to your computer or network via the internet. They are set up to stop unwanted traffic from specific locations, applications, websites, or specific users.

Firewalls can either be a hardware or software. Both options for a firewall are great, it's just figuring out what works best for your needs. Hardware tends to be the safer choice since it's a separate device. The software versions of firewall are integrated right into the computer or operating systems. Some routers now come with a simple firewall integrated into them to help keep you safe. This is a great option with many companies with remote workers or employees working from home. 

Firewalls are a necessity in today’s world if you want to keep your business and employees safe. They are simple to have an IT company manage and keep your firewall working and updated. Staying safe in the digital world can be challenging.
