Abstract: This paper analyses DNS firewalls in other to check if they can be a useful tool to protect children at home or at school, making it possible to control access to websites or cloud services that may be inappropriate or dangerous for them. Using this technology helps to protect the safety and privacy of minors by blocking the connection to Internet services that are inappropriate for the user's age, blocking malicious websites that contain malware or blocking phishing pages that try to capture their credentials. There are DNS firewalls that have additional features such as automatic updating of restricted domains from public lists or other features such as the ability to block access to game servers, streaming platforms, or social networks during configurable time periods, allowing that at school times children cannot access certain content. To analyse the usefulness of this technology, the requirements of the school and family environment are determined. Different open-source solutions, or the solutions that are free of change, are checked to obtain the level of compliance with the requirements as well as their characteristics, functionalities, hardware requirements, but also its architecture flexibility that can be adopted for its configuration. The solutions and architectures evaluated as the most appropriate are test in this paper during a period in a local family network, obtaining the final conclusions and proposing an implementable solution.
