So, does a DNS firewall reduce the risk of ransomware attacks? This is one of the frequently asked questions when it comes to internet security management, especially since ransomware attacks have become increasingly common.
The number of incidents is only growing and is becoming a concern not only for large companies and governments. In fact, medium and small businesses , especially those that handle and store sensitive data, have been working to mitigate risks and establish levels of control and security for data and networks .
DNS firewall for everyone
Size doesn't matter... This is a popular saying that, unfortunately, perfectly exemplifies the current situation and risks of ransomware attacks.
Do you know how hackers choose companies to attack with ransomware?
First, they choose the weak and unprepared ones , without any information security policy or process on the internet. It's that simple.
Secondly, the least secure ones contain an abundance of sensitive data , which makes it easier to demand payment .
However, every computer is a primary target and gateway for ransomware attacks or other forms of malicious code. After all, just as DNS is the gateway for all data traffic and access flow, it is also the gateway for any and all types of attacks .
That's why a good internet security solution starts with controlling and monitoring DNS (Domain Name System).
So, we can immediately answer the question in the title of this article: Does a DNS firewall reduce the risk of ransomware attacks?
The answer is a big, resounding YES!!!
Without a doubt, when properly configured, a good DNS firewall can indeed reduce the risk of ransomware attacks .
When it comes to internet security, downplaying or ignoring the need to establish and manage access rules based on DNS queries is definitely not a good idea.
Going back to the popular expression, regardless of company size, all companies should dedicate proper and professional attention to the security of their data and information .
How does a DNS firewall work?
Just to illustrate, before we proceed, watch this short video (it's only one minute long) which, in a didactic and very simple way, explains how a DNS firewall works and its importance in reducing the risk of ransomware attacks .
A DNS firewall works through processes that ensure the security, control, and monitoring of data and internet access flows on a network .
Unlike a traditional firewall, a DNS firewall , in addition to blocking and redirecting users to prevent access to malicious websites, also acts more broadly, at different layers and phases of the DNS, reducing the risk of data loss, blocking, or compromise .
In principle, this technology makes it possible to protect more data , helps isolate compromised devices , and keeps information about malicious attacks visible and up-to-date through an automated threat feed .
A good tip for all sizes of businesses, but especially for medium and small businesses, is to research and learn about affordable solutions and technologies .
Both economically and in terms of ease of use, not all solutions available on the market are cheap or simple to operate . Furthermore, the support provided is invariably only in English.
Since small and medium-sized business owners end up being directly involved in the management processes of their companies, it makes all the difference to be able to monitor and control internet security processes in Portuguese in a completely intuitive and easy way .
Why invest in a DNS firewall to reduce the risk of ransomware attacks?
Similarly, the answer to that question is simple and entirely pragmatic. That is, because prevention is easier and cheaper than cure .
Furthermore, without prevention or protection to avoid ransomware attacks, the impact and resulting losses cannot always be reversed . Consequently, they can be fatal for any company , especially for medium and small businesses.
Moreover, every entrepreneur knows the pain and the joy of owning their own business. Because of this, they are almost always practical and objective. They know their company better than anyone (or they should) and understand the importance of management and cost-effectiveness .
By analogy, managing internet security processes is directly connected to saving resources , freeing up resources for investments and for each company's business operations.
The lack of investment aimed at mitigating ransomware attacks, for example, is in itself a risk that businesses should not take . This administrative omission can lead to:
- losses due to data loss (temporary or permanent);
- losses resulting from the interruption in the production or provision of goods and services;
- losses due to the shutdown of revenue-generating activities and operations.
- losses incurred in an attempt to remedy the situation or succumbing to extortion in a ransomware attack; and
- damage to your company's reputation.
But how exactly can small and medium-sized enterprises prevent cyberattacks?
Regardless, a lack of investment always leads to losses. It is up to companies to manage these risks in the same way they seek, for example, to avoid wasting employees' time on websites and social media.
The solution to this type of waste and to reduce the risk of ransomware attacks or more common cyberattacks undoubtedly lies in technology .
In this sense, it should begin with good internet security practices and a suitable, customized DNS firewall solution .
Reduce the risk of ransomware attacks with a DNS Firewall.
Given the increasing number of cyberattack incidents and the need for investments to reduce the risk of ransomware attacks , a DNS firewall solution is essential .
Small and medium-sized business owners need to understand that their companies are indeed targets when it comes to demanding money to unlock or return data and access.
In contrast, the less prepared they are, the easier and more preferable they become for hackers and ransomware attacks, regardless of the motivation .
Regardless, some malicious attacks are simply intended to infiltrate as many systems as possible and build a "reputation" for the hacker. Others aim to access data and information that allows for a strategic advantage in decision-making. Still others, for example, aim to steal data for sale to competitors or on the Deep Web.
That's why it's so important to implement a DNS firewall to prevent, protect against, and reduce the risk of ransomware attacks or other forms of cyberattacks.
In this sense, it's necessary to understand that there is no magic solution to prevent attacks. What does exist are good practices and the systematization of information security processes through technology . Also, it's through DNS that malicious attacks begin.
In short, the purpose and relevance of a DNS firewall is to reduce the risk of ransomware attacks.
