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.

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.
