A DNS amplification attack is one of the most powerful DDoS attacks that can be used to bring down an entire network. The attacker will manipulate DNS to flood a victim with large numbers of UDP packages, which can either be amplified into smaller packets or fragmented.
The attack uses IP Spoofing, Open Recursion and Amplification to send a stream of queries continuously to DNS servers which are vulnerable. This can be achieved by using a group of infected PCs that generate a massive amount of queries.
There are several ways to defend against these amplification attacks. Among the most effective methods are securing open network services, such as DNS and NTP, and limiting the number of open network servers that can accept queries. These measures can reduce the risks of DNS amplification attack, which could result in a massive disruption of services to other network systems.
The Amplified DNS flood is a method for DNS DDoS amplification which takes advantage of the open recursive DNS servers infrastructure. In this attack, an attacker first sends small DNS query with a fake IP address to DNS servers open to the attack. DNS resolvers send the request back to the victim with a much larger response than the original 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. This DDoS attack, unlike many others, uses a simple amplification protocol. It doesn't use TCP and is capable of handling large amounts of traffic.
Despite the efficiency of UDP communication, there are some drawbacks to this type of amplification. 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.
This type of amplification can also result in packets being fragmented, making the attack more difficult to detect. Installing a firewall in between your source site and the public network will help you mitigate these types of attacks.
Other techniques can also be used to defend against this type of attack, such as rate limiting, ports limiting, and threat intelligence. These techniques can be used to limit the amount of open DNS servers that accept traffic.
Using network monitoring tools like SNMP and Netflow to identify amplification attacks before it's too much is very helpful. It is even more important if you are monitoring your network in real-time.
