Domain Name System Security (DNS security) is essential to protect your DNS infrastructure from cyberattacks. The DNS system has some design limitations that makes it vulnerable to a wide variety of attacks, which can include spoofing, denial of service, or the theft of private information.
DNS attacks are often combined with other cyberattacks and can be used as a distraction for security teams. Your organization must be able to rapidly detect and prevent DNS attacks so that they are prepared to handle simultaneous attacks, which can severely impact finances, workflow, and reputation.
The practice of DNS security protects your business from these common cyber threats:
DNS spoofing: This occurs when forged DNS data is introduced into a DNS resolver’s cache, causing it to return an incorrect IP address for a given domain. This diverts traffic to malicious sites or anywhere else the attacker desires. These sites can often be replicas of the original site that are used for distributing malware and illegally capturing login information.
DNS tunneling: This attack takes advantage of web protocols to tunnel through DNS queries and responses. Attackers can use these protocols to pass malware or stolen data circumventing firewalls.
DNS hijacking: Targets a website’s DNS record on the nameserver to redirect queries to a different domain name server.
Denial-of-service (DoS): These attacks send their targets copious amounts of traffic or information, causing them to crash or respond very slowly. This causes computer systems and networks to fail so that their intended users are unable to access them.
DNS security is crucial for protecting the internet's DNS infrastructure from cyberattacks. Since attackers frequently target DNS, DNS security tools play a vital role in safeguarding against threats such as malware, phishing, and denial-of-service attacks.
