How to combat DNS attacks?

DNS tunneling is a form of attack that hackers use to modify DNS data. For a few years now, many popular websites such as Twitter, Spotify, Netflix, Amazon have been attacked by DNS hackers. As a result, these sites have become inaccessible to Internet users for a long time. But what are these attacks really about? To answer this question, we will tell you about the 3 DNS attacks and how to fight them. Check them out here.

Attack 1: DNS amplification attack (DDoS-like)

At this level, attackers do not intervene to threaten DNS systems. Instead, they use DNS services to augment the distributed denial-of-service (DDoS) intrusion. To learn more, click on this site These attacks are not the most well-known. Amplification attackers use a bootnet to send a plurality of lookup requests to open DNS servers. To combat DDoS attacks, it is to host your site on multiple servers so that if one server becomes overloaded, another is available. By doing this, IP addresses of traffic can be blocked if the attack is weak.

Attack 2: DDoS attack on DNS

To combat many types of systems, DDoS attacks can be used. This allows DNS servers to be included. Because of this, a successful DDoS attack against a DNS server, leads to an outage that makes users unable to browse the website. DNS server attacks are a danger to network security and should be taken seriously. In order to reduce and prevent the consequences of such an attack, companies and providers should implement safeguards. Make sure the network is secure and opt for infrastructures that are housed and maintained by DNS specialists.

Attack 3: DNS Cache Poisoning and Spoofing

DNS poisoning aims to drive users from one website to another fraudulent website. Once the user types in their email to be able to log in, the DNS that has been poisoned, automatically displays the fake page. Users entering their names do not realize that the website they are visiting is fake. The best method to prevent such DNS cache poisoning attack is to regularly update the program. It will also be necessary to think about deleting DNS caches on local machines and reducing TTL times.
