In today\u2019s online world in which almost 60% of the world uses the internet, protecting yourself from malware and malicious content is very crucial. KeepSolid provides a DNS firewall to help you do just that. To understand how the firewall works, we need to look at how DNS, or domain name system operates. DNS works like a phonebook but just for the internet. When you type in an address, such as techwalls.com or google.com, the webservers won\u2019t know how to route your request as they understand numerical IP addresses. DNS helps by looking up the domain and converting it to the machine-readable IP.<\/p>\n\n\n\n\n\n\n\n

With the brief introduction of DNS, let\u2019s discuss KeepSolid firewall. The DNS firewall works by filtering out resolutions by the DNS that include malware, adult content and other malicious sites. If a resolution is a known site and is blocked, you will not have access. However, this is customizable to restrict or allow what can be seen on your internet. Recommendation would be to use the principal of less privilege. This essentially means to block most by default and allow what you need, rather than allowing all and blocking what you don\u2019t. The firewall is available for both computers and mobile devices on all platforms. This is great for all users with different devices.<\/p>\n\n\n\n
