While there is continuous development of new means of protection against DNS attacks, hackers are also working hard in coming up with new ways of demolishing them. Remember, there is no way of annihilating all DNS attacks. You can, however, beat them by using the latest versions of protective software.
Authoritative and Recursive Servers
One of the ways hackers may use to compromise your dns security is blocking your access to an internet service. Usually, they do this by filling the website you are keen on visiting with so many queries that the traffic volumes become too high for you to access it. In addition, hackers may create malware in a computer with the aim of spreading it to all other computers in the same network.
Authoritative servers only respond to queries they are sure of and enable the disabling of recursive. To boost security, you can always include another DNS server with separate authoritative and recursive features but within one appliance with the other one. Additionally, efficiency and reliability of the DNS services is greatly improved.
Vulnerability in the software of your DNS server may be easily overlooked, leaving a loophole for attackers to exploit in an attempt to compromise it. The best way to protect yourself against such an unexpected attack is running different algorithm types on different DNS engines, thus confusing the attackers. In the event that the dns security system gives a new security alert, you can temporarily move to an alternative engine. Meanwhile, security upgrades on the original engine can be patched, tested and validated. In addition, it would be hard for attackers to know which software is in operation.
The basic means of putting up a guard against malware is installation of a DNS firewall. It prevents diversion of your workstation to suspect sites. In addition, the firewall prevents spreading of infectious malware by putting the infected user in Walled Garden isolation. Therefore, the administrator will receive notification whenever a user is infected and take the necessary action.
The rise of internet use in cloud solutions, mobile and billions of other devices connected to the internet presents a good opportunity for DNS attackers to engage in their trade. To be safe, therefore, you must always be ahead of the game by being on the lookout for up-to-date dns security strategies.
