DNS is very important for browsing the Internet. They allow users, by entering a domain name, to get to the correct path of a web page. Now, the truth is that there are cyber attacks that can compromise them. It is something that is present on the Internet and that could pose a significant problem. In this article we focus on explaining why it is essential to protect DNS for telecommuting .
Telework is increasingly present and you have to protect yourself
Keep in mind that remote work is something that is increasingly present in our day to day. There are many users who carry out their functions from home, without having to physically go to an office. Current technology allows this possibility.
However, this is also a challenge for security . It is not enough simply to have the appropriate means to telework, such as an Internet connection, computer equipment and the necessary software. You also have to take into account the importance of everything being properly protected.
Having security programs, keeping equipment up-to-date, protecting our network… All this helps make teleworking not only an option for many companies, but also safe. In this way we avoid that the data and information of the organization, as well as that of the employee himself, can be compromised.
Among all that we can keep safe, something very important is the DNS. We must avoid attacks that may pose a problem for our security. We already know that we can run into DNS cache poisoning , for example, which would cause the user to be redirected to an unsafe page when browsing.
Why Protecting DNS Is Important When Working Remotely
Many business networks are protected against all kinds of threats. They have firewalls, computer programs on the devices, perfectly encrypted wireless networks, systems to prevent DNS attacks …
What happens when we work from home? It is possible that when entering a web page, accessing a company service, security is not the same. It may be that our network is not well protected, that there are possible intruders, that our computer has viruses, etc. There are many problems that can be.
Let’s assume that our network has suffered a DNS poisoning attack. We try to enter company pages and we find that it redirects us to a different one. Even this process could go unnoticed by users.
This could lead to the leakage of important data and information from an organization. Not only the privacy of users, remote workers, but also the entire company could be compromised.
PDNS Digital Roaming
That is why it is essential to protect computers and prevent attacks that could compromise DNS resolvers. There is an application called PDNS Digital Roaming , available for Windows 10, that detects when a device is being used outside the corporate network and redirects DNS traffic to PDNS using a DNS over HTTPS encryption protocol. The goal is to offer users the same security protections as if they were connecting from the corporate network.
Its creators indicate that it is not a VPN, but rather an application that aims to encrypt and redirect DNS traffic in order to keep users safe. When installed on the computer, users can verify that DNS traffic is directed to PDNS and everything is encrypted.
Therefore, as a conclusion we must say that it is very important to protect our equipment at all levels . It is essential to have a good antivirus and other security tools, as well as to keep systems up to date. On many occasions, vulnerabilities arise that must be corrected to prevent the entry of attackers who compromise us.
Also, beyond the computer itself and the programs that we have installed, it is necessary to protect the networks and, as we have seen in this article, the DNS traffic. Preventing us from being redirected to fraudulent pages, preventing them from infecting us simply by entering a website, is very important. We have seen the particular case of remote workers, which could even compromise the information of a company, but we must also apply it to private users.
