DNS amplification can be one of most powerful DDoS techniques to bring down a whole network. The attacker will use the DNS system to flood the target with large amounts of UDP packets. These packets can then be amplified and even fragmented.
The attack employs a combination IP spoofing with open recursion as well as amplification. It sends a steady stream of requests to DNS servers who are vulnerable. The attack can be carried out by a botnet, which is a collection of infected computers that produce a large number of queries. This traffic is then sent via an amplification records to DNS servers.
You can defend against these attacks in several ways. Secure open network service, like DNS or NTP, as well as limiting the number servers open to accepting queries, are the best ways to protect against these attacks. These measures help to reduce the likelihood of DNS amplifications, which may result in massive denial of services for other systems or services on the system.
Amplified DNS flooding is a method that's commonly used to amplify DNS DDoS attacks. It takes advantage open DNS server infrastructure. In this attack, an attacker first sends small DNS query with a fake IP address to DNS servers open to the attack. The DNS resolvers then send the query back to the victim's domain with a response that is considerably larger than the initial request.
This reflects the attacker's original intent and provides a way to send large amounts of traffic to the victim without it being detected. Unlike many other DDoS attacks, this type of amplification uses a simple protocol that doesn't require TCP and can handle large amounts of traffic easily.
UDP has its advantages, but also some disadvantages. TCP uses a three-way handshaking, which makes it impossible for most spoofed TCP to work. This is because the TCP/IP Stack can send RST (reset packets) in response to unexpected TCP requests.
Another drawback of this type of amplification is that it can result in the packets getting fragmented into smaller ones, which can make the attack harder to detect. To avoid these issues, deploying a firewall between your source sites and the public network can help mitigate these kinds of attacks in real time.
There are several other techniques that can be deployed to protect against these kinds of attacks, including rate limiting, port limiting and threat intelligence. They can limit the number open recursive DNS server that can accept traffic, and also help clean up any malicious TCP/UDP link that is being sent across your system.
Using common network throughput monitoring tools such as SNMP and netflow can be very useful for identifying an amplification attack before it is too late. This can be especially true if your network's throughput is monitored in real-time.

You can also deploy a static website to any platform that supports PHP such as WordPress, Drupal Joomla! Magento PrestaShop and others.
Static websites are typically easier to maintain, as they don’t have to constantly send requests between servers. A static web page loads faster as there is no need to forward requests back and forth among servers. Smaller companies with limited resources and the time required to manage websites properly will find static web pages more beneficial.
