Everything You Need to Know About DNS Protection
DNS plays a critical role in facilitating communication between devices and servers on the internet. However, its inherent design vulnerabilities and lack of built-in security features make it susceptible to various cyber threats, including DNS spoofing, cache poisoning, DDoS (Distributed Denial of Service) attacks, and DNS hijacking. A compromised DNS infrastructure can lead to significant disruptions, data exfiltration, and unauthorized access to sensitive information, underscoring the importance of robust DNS protection measures.
Common Threats to DNS Security:
DNS Spoofing
DNS spoofing involves the falsification of DNS data to redirect users to malicious websites or servers. Attackers exploit vulnerabilities in DNS servers or manipulate DNS responses to redirect traffic to fraudulent destinations, leading to potential data theft or malware infections.
Cache Poisoning
Cache poisoning attacks involve corrupting the DNS cache of a recursive resolver with malicious data. By injecting forged DNS records into the cache, attackers can redirect legitimate traffic to malicious servers, intercept sensitive information, or launch further attacks.
DDoS Attacks
DDoS attacks targeting DNS infrastructure can overwhelm DNS servers with a deluge of traffic, rendering them unresponsive and disrupting normal DNS resolution services. These attacks can result in service downtime, loss of revenue, and reputational damage for businesses.
DNS Hijacking
DNS hijacking occurs when attackers gain unauthorized control over a domain's DNS settings, allowing them to redirect traffic intended for legitimate domains to malicious destinations. This can lead to phishing scams, identity theft, and unauthorized access to sensitive accounts or data.
