“Security.” It’s a word that we are all familiar with, but it can have many different meanings depending on context. Security to people nearing retirement age may mean financial security for their future.
At a large event like a concert, it could mean both security guards and the overall security of the event.
However, as time goes by, the word security has become increasingly related to the digital world.
Using the Internet to pay bills, access banking information, or even applying for loans is commonplace. We must be prepared to protect our identity and personal information.
Now, whether you are talking about your home or your business, network security starts with a firewall.
So what is a firewall?
A firewall, in terms of network security, can be a physical device that your incoming and outgoing data is routed through. It could also be a program on your device that can strengthen and supplement your devices’ security.
Both of these have different capabilities and purposes and can be used individually or together.
While there are different types, their essential function is the same. A firewall is put in place to allow or deny traffic, based on a set of security rules.
In a business setting where many staff members use a computer daily, a firewall can be put in place to block unwanted traffic.
A simple security rule to check for secure certificates can stop unwanted traffic easily.
Websites have security certificates, so when you access a page, your firewall can check the certificate. If the certificate is digitally signed and known as trusted, the firewall will allow traffic to proceed.
Search results can often display links of potentially harmful websites.
A firewall adds a layer of security making sure your employees don’t accidently find themselves on a website that could compromise your network.
This same principle works for home networks and can allow you to set some security rules. These rules can be put in place to help keep Internet usage safe, especially with children around the house. A firewall can also block certain content.
In an office setting, you could turn off access to social media to stop staff from accessing sites that aren’t needed to complete work.
It can block certain search engines and even limit the use of unsecure versions of websites.
At home, you can block content from websites you don’t want your family to have access to.
There is also the option of having active network times. You can have your Wi-Fi network only active during business hours, keep your kids off their devices at bedtime, or limit access to certain days.
There are many other things that your firewall can do to help keep your network safe.
Keeping your network secure has the potential to save you thousands of dollars, depending on the number of devices and your dependency on those devices.
Safety and security always has a high value to you. It can also help you rest easier knowing that either your business, or your family, is a little bit safer.
