​How firewalls work against threats?

04/03/2019

You likely have seen your computer display a message about your firewall. You know it keeps your computer safe, but what do firewalls do to protect you?


How do firewalls work?

Firewalls are software programs that prevent someone from accessing your computer. It identifies inbound threats and isolates them so that they don’t have a chance to wreak havoc with your system.


They’re not just good at keeping viruses, malware, and so on out, though. They can also be used to prevent the transmission of sensitive data out of your system. So, if you have an employee who is trying to transmit protected files, the firewall can prevent that.


Finally, a firewall might also be programmed to block what it deems malicious sites or sites that are considered a no-no. If you’re running a business and would prefer that your staff do not access social media while at work, the software can be programmed to block access to those sites.


Essentially, a firewall works by following a set of parameters that your IT professional puts in place. If it comes across a request, incoming or outgoing, that falls outside of those parameters, it will block that request.


By blocking any requests that do not fit the preset parameters, it ensures that your entire system is safe.
