The Definitive Guide on DNS filtering
What is DNS filtering?
DNS filtering is the process of using the Domain Name System to block malicious websites and filter out harmful or inappropriate content. This ensures that company data remains secure and allows companies to have control over what their employees can access on company-managed networks. DNS filtering is often part of a larger access control strategy.
How do DNS filtering services work?
DNS filtering is a type of network security solution that blocks users from accessing restricted websites, applications, and content. If you want to prevent the people on your network from accessing certain content, there are several ways to go about it. You can use a proxy server to filter all of the data that is going through, but that would mean that you would have to make sure that you had proxy services setup for every device on your network. You can also go with a DNS filtering service that lets you control everything from one centralized location.
If the malicious site is on that company’s blocklist, the DNS resolver will block the request, preventing malicious-website.com from loading and thwarting the phishing attack.
DNS filtering can blocklist web properties either by domain name or by IP address:
By domain: The DNS resolver does not resolve, or look up, the IP addresses for certain domains at all.
By IP address: The DNS resolver attempts to resolve all domains, but if the IP address is on the blocklist, the resolver will not send it back to the requesting device.
What is the difference between DNS filtering and web filtering?
DNS filtering is a form of web filtering and it is used to stop certain websites from being accessed by certain users. It is achieved through the use of a DNS server or a DNS resolver. The DNS server stores the domain names that are to be filtered and then forwards them to the users who need them.
Web filtering is used for blocking websites that are considered as dangerous or unsuitable for some reason. It can be used either for preventing access by specific users or all users, depending on what level of security you want. For example, if you want to block all your website visitors from accessing your website, then you will use web filtering. If you just want to block certain types of content, then you will use DNS filtering .
How does DNS filtering block prohibited content?
The DNS is the root of the Internet and it is responsible for translating domain names into IP addresses. It also acts as a gate between the Internet and your computer. This gateway is used by many websites to send content to users, but it is also used by hackers to send malicious content through DNS filters.
Why do we need DNS filtering ?
DNS Filtering is the process of changing the domain names in a website from one to another. A DNS server is responsible for translating an IP address into a domain name and vice versa. This can be done using a combination of static or dynamic IP addresses and/or DNS servers.
DNS filtering is not just about employers blocking sites they don’t want their employees to access. It’s also a very important cybersecurity measure that prevents you from accessing malicious sites that can administer phishing, ransomware attacks.
Unfortunately, there are a lot of people who compromise websites in order to trick people into handing over their login credentials, scamming them out of money, and causing businesses to be shut down.
What are the Benefits of using DNS filtering
DNS filtering is a mechanism that allows organizations to control which websites their users can access. by modifying the DNS servers and/or other bits of configuration, so that only specific IP addresses or subdomains can be loaded.
