DNS, which is the abbreviation for Domain Name System, is an important and powerful tool that is behind the working of the entire Internet. Earlier, when the Internet was at a nascent stage, there used to be IP addresses which would take the user to the website he or she wishes to visit. At a time when the number of websites was just a handful this process did not seem like much of a problem. However, as the Internet continued to grow and more and more sites kept on adding, remembering a string of digits (which is the IP address) became impossible. Human minds cannot remember complex combination of numbers. However, what it can remember is names. Thus the concept of DNS came into existence.
What is DNS and how does it work?
As already mentioned DNS stands for Domain Name System. It is basically the name give to the website which can be remembered by the human mind. Every website has an address which is called the IP Address. This address is basically a string of digits. DNS is the alphanumeric name assigned to that IP Address which allows the user to easily remember and get linked to the website. Whenever a person types in the DNS the browser asks the DNS Server to locate the IP address associated with it. This DNS server may contact other servers in order to find the IP address and once found returns the page to the machine. Greatest advantage about this system is that DNS servers get updated on a regular basis without any specific organization being responsible for the job. Thus, this becomes a major shared database and makes communication easy.
DNS Security Issues
With ease come some compromises. In case of DNS this has been the lack of security. At earlier stage no one considered making this a highly secured system. Adding any security to the system at a later stage without disintegrating the system became impossible. However, this opened up the Internet users to a large number of threats from cyber criminals. Issues like hacking, spamming, and even DoS (Denial of Service) started emerging as the Internet grew in size and people with malicious intent became highly sophisticated. The fact that DNS is inherently insecure is a truth known globally. This is why it is important to ensure DNS security, to safeguard the interest of the enterprises as well as their clients.
DNS Security Features
DNS security is one of the best in business that offers all-round protection against any cyber attack. It secures the interest of the organization and protects the users as well. The security is provided mainly through the DNS Firewall, which acts as an added security layer protecting the DNS against hack.
The stages of protection offered by
» Protection of DNS against hack using firewall. This will effectively deter any unauthorized access and exploit of DNS.
» Malware protection and IP blacklisting. This is done on a global scale and is updated on a regular basis to allow detection of recurring and recent malwares and blacklisting IPs from where these originate.
» Real-time filter providing protection against newest threats and compromised IPs which have not yet been updated on the global database.
DNS Security is rated as the top line security available on global scale. It has been conceived by the best in security business and takes holistic approach towards protection of DNS.
