As the number of computers and systems in the world increased, the computer files stored on HOSTS reached enormous sizes. One of the biggest challenges of the HOSTS system was that each computer had to be given a different name. It was not possible for this system to be constantly up-to-date. This led to some developments in this field. The most important of these developments was the advancement of DNS security solutions to overcome these problems.
DNS enabled computers and IP addresses to have a hierarchical structure. This structure eliminated the need to keep records of all systems active on the Internet in a single center from the day it developed. According to statistics in 2019, the data demonstrates the global trend of internet hosts using the domain name system between 1993 and 2019. There were around 1.01 billion internet hosts accessible on the DNS in January 2019. It can be said that this rate has increased over time, as the DNS system continues to develop.
Unfortunately, with the increase in cyber attacks, the protection of enterprise networks and systems has become vitally necessary. To protect an enterprise from numerous cyber threats, DNS security should be one of the top priorities. Let’s examine DNS security and the benefits it will bring to your company.
What is DNS?
DNS is short for “Domain Name System”. DNS is used to convert names to IP. Interestingly, DNS is a system that can grow up to 256 characters. The device name and Internet “domain” is shown by the host. By identifying their IP addresses, DNS enables devices using computers or computer systems to connect with one another. The domain naming system is utilized in place of IP addresses since they are complicated and difficult to memorize.
Keeping track of every IP address and domain name on the network is one of DNS’s primary goals. The widely known BIND program is employed for this purpose. DNS can quickly determine where on the Internet a site is when a user attempts to access it. DNS is a system that names each domain on the Internet and links them together.
Why Should We Use DNS?
When DNS was created at the beginning of the internet, cybersecurity was not a consideration. Nowadays, the biggest issue with this is that it cannot be stopped and is very challenging to follow in a professional context. Therefore, a number of technologies that enhance DNS security remove issues that hackers can take advantage of. Most of the time, DNS security solutions avoid or significantly reduce the dangers connected with DNS resolver systems that block spoofing efforts.
Protection from phishing and malware assaults
The DNS can be used to block dangerous websites linked to phishing or the propagation of malware. It can serve as a filter to only allow trustworthy websites or to prohibit particular website categories. By adding its known hosts to a blacklist, DNS occasionally also enables it to defend against advertisements.
Possibility of quicker lookup
Compared to ISP DNS servers, secure DNS servers typically provide quicker lookups. They could also have a variety of defenses and several flaws, including filters on an ISP’s server. Users may eventually benefit from increased connection speeds and enhanced dependability. Employee productivity may also rise as a result.
Typo fixing
Your first search could have been misdirected if you searched for other addresses instead of the address because it’s really simple to misspell website address names when you’re pressed for time. Because hackers frequently register different misspelling names of legitimate websites and exploit them to spread harmful malware, this poses a severe threat. The initial crowds of guests arrive quickly.
Stability
The IP address of a website may alter for a variety of reasons. Visitors must thus stay informed about this information. This is sometimes a very arduous process. But to make things easier, the DNS system refreshes IP addresses often, saving users’ time and effort.
How does DNS work?
It is essential to understand the fundamentals of DNS security’s operation before delving into its specific configuration. Each computer connected to the Internet has a specific IP address that is used to identify it when engaging in data transmission. Knowing where to send data packets so they can get to their destination is crucial.
Web browsers often conduct these exchanges by consulting the DNS servers of their ISP. DNS servers can alternatively be categorized as recursive resolvers and authoritative servers. Recursive resolvers know where to search even if they don’t have the precise address, whereas proxy servers keep the actual IP addresses of websites.
The user experience becomes simpler with this technology. Users simply need to remember the website’s name in this case, whereas DNS servers must obtain lengthy IP addresses. You utilize a DNS server each time you visit a website. Everyone now has access to the internet thanks to DNS.
Can DNS Security prevent cyberattacks?
Even small changes can have a huge impact on cybersecurity, as DNS is what holds the internet together. Monitoring DNS queries originating from your company and returned IP addresses can significantly improve network security. One of the first things to do to stop the attack instantly is to flag any unusual DNS behavior.
Finding a DNS provider that will allow the use of a privately run DNS server is another possibility. They include special security mechanisms to restrict dangerous DNS connections and can be set up to detect suspicious behavior. It is a really useful feature as the attack can be completely avoided as the connection is blocked at the DNS layer.
Various malicious websites and their IP addresses are listed in a large number of public databases. Protecting against risky requests may be achieved by configuring a DNS to filter reported addresses.
Conclusion
From everything we’ve said, it’s clear that DNS functions something like the internet equivalent of a phone book. In other terms, the DNS system may be compared to a massive phone book that stores IP addresses and domain names. This technique allows us to connect to our browser and access websites by inputting meaningful or catchy domain names rather than IP numbers. We would have had to remember each website’s IP address if the DNS system hadn’t been built.
This system is designed to provide security and control of users and network visitors. Your IP address is stored and protected here as people access systems and networks. Thanks to DNS, you will be directed to where you want most safely. Unknowingly, you utilize a DNS server each time you visit a website. It is one of the foundational elements that enable the internet.
