DNS amplification attacks are among the most powerful DDoS attack that can be used in order to bring an entire network down. 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. A botnet of infected machines can be used to send an enormous amount of queries. These are then sent by an amplification record to DNS servers that are vulnerable.
There are many ways to defend yourself against these amplifications attacks. One of the most efficient methods is to limit the number open servers that are allowed to accept queries and secure network services. These measures help reduce the risk of DNS amplification attacks, which can result in a massive denial of service to other systems and services on the network.
The Amplified DNS flood is a method for DNS DDoS amplification which takes advantage of the open recursive DNS servers infrastructure. In this attack, the attacker first sends small DNS queries with a spoofed IP address to open DNS servers that are susceptible 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 intention and provides a method to send large quantities of traffic to the target without it being noticed. This DDoS attack is different from others because it uses an amplification protocol that does not use TCP. The protocol can handle large traffic volumes.
UDP is a very efficient way to communicate, but it has some disadvantages. TCP requires that there be a 3-way handshake. This prevents the majority of spoofed TCP attempts from working, because the TCP/IP layer can send RST packets in response to any unexpected TCP-handshake requests.
Amplification of this kind can lead to packets fragmenting into smaller pieces, which makes it harder to detect the attack. In order to avoid these problems, installing a real-time firewall between your site source and the public internet can mitigate these attacks.
There are several other techniques that can be deployed to protect against these kinds of attacks, including rate limiting, port limiting and threat intelligence. These can help to limit the number of open recursive DNS servers that can accept traffic and can also help to clean up any malicious TCP/UDP links that are being sent across your network.
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 true, especially if your network throughput is monitored live.

Is WordPress a CMS?
The answer is yes. It's a Content Management System (CMS). CMS is a way to manage your website content without having to use an application such Dreamweaver/Frontpage.
WordPress is free! Hosting, which is usually provided by your ISP, is free.
WordPress was initially designed as a blogging platform but now offers many different options, including eCommerce sites, forums, membership websites, portfolios, etc.
WordPress is very easy to set up and install. Download the file from their website, and then upload it to your server. Simply visit the domain name from your web browser, and then log in to the new site.
After installing WordPress, you'll need to register for a username and password. Once you log in you'll be able access all your settings via a dashboard.
From here, you can add pages, posts, images, links, menus, widgets, and plugins. This step may be skipped if you feel confident editing and creating content.
If you prefer to work with a professional web designer, you can hire them to manage the entire process.
What is a responsive web design?
Responsive web design (RWD), is a way to create websites that display responsively on all devices, including smartphones, tablets, desktop computers, laptops and tablets. This allows users the ability to view a website simultaneously on different devices and still have access to other features like navigation menus, buttons, and so forth. RWD is designed to ensure that a user can view a site on any size screen.
A website that sells primarily through eCommerce would be an example of this. You want your customers to be able to purchase products from your store, even if they are viewing it on a phone.
A responsive site will adapt to the device used to view it. A website that is viewed on your laptop will display the same way as a desktop website. It will look different if you view the page from your phone.
This means that you can create one website that looks great across all devices.
