DDoS (Distributed Denial-of-Service) attacks have been around for long now and they are continually evolving. DDoS attack in simple terms means the use of multiple compromised systems to target a network with excessive traffic. The purpose of these attacks is to cause service disruptions or complete shutdowns to hinder business growth. Unlike other attacks that aim to steal data and company assets, DDoS attacks are mostly about stopping daily operations.
Most people confuse DDoS with DOS (Denial of Service) but they are different. DOS comes from a single source, while DDoS uses multiple sources which makes it difficult to counter and prevent it. Not having any robust cybersecurity solution in place can make these DDoS attacks consequential by causing reputation damage and financial losses. These attacks have also evolved, now there are various types of DDoS attacks that are attempted for different purposes.
Eager to know what these different types of attacks are? Then you are on the right page because this article will throw light on the top types of DDoS attacks you must protect your company from.
5 DDoS Attacks That You Must Defend Against
The DDoS attacks are categorized based on several factors including the type of traffic used, attack duration, method of attack, and the attack’s target. While the main categories are protocol attacks, application-layer attacks, and volumetric attacks, there are various sub-categories of these attacks. This article will throw light on those attacks in-depth, keep reading to uncover them and discover solutions to prevent them.
Here are 5 DDoS attacks you must protect your company from:
DNS Flood
This is one of the common types of DDoS attack that targets the Domain Name System (DNS) servers. It overwhelms the server with a high volume of DNS requests. Cybercriminals send a high number of requests to the targeted DNS server with spoofed IP addresses, which stops the server from responding to legitimate queries.
This mainly causes service disruptions and inaccessibility of websites that rely on targeted DNS servers. As a result, the downtime increases which leads to a loss of revenue. To prevent such attacks you need modern-day cybersecurity solutions. This is why owners opt for professional cyber security services UAE to strengthen their security against such attacks.
UDP Flood
UDP (User Datagram Protocol) floor is another type of DDoS attack that overwhelms the targeted system with UDP packets. These attacks are highly effective in making the server, bandwidth, or system unavailable to legitimate users and requests. Additionally, unlike other attacks, UDP floods require fewer resources to execute.
Attackers send a large amount of UDP traffic with spoofed IP addresses on random ports of any particular system or server. The server then checks the incoming packet for a specific port and issues a response. With the high volume of packets, the server can easily become exhausted and become unavailable to the normal traffic.
ReDos
ReDoS or Regular Expression Denial of Service is another type of DDoS attack that you may not have heard about. This attack usually targets vulnerable applications and uses regular expressions to parse user input. To trigger a regular expression from the application attackers send malicious input.
As a result, the application enters into an infinite loop and eats up all its resources. The application then becomes very sluggish to its legitimate users or even goes down which can be consequential.
Spoofed Session Flood
A spoofed session flood is also recognized as a Fake Session Attack that has a similar process to most other attacks but a different approach. It affects the targeted system by creating a high number of fake sessions with the help of spoofed IP addresses. The reason why this attack is effective is because the spoofed requests appear to be from legitimate sources.
Considering this, the targeted server then allocates its resources to handle the new sessions initiated by attackers. As the server continues to handle these sessions its resources such as CPU, RAM, and memory get consumed. Eventually causing it to get exhausted which can cause performance degradation.
HTTP Flood
This is one of the most common types of DDoS attacks that most organizations encounter nowadays. These attacks target any specific web server to overwhelm it with excessive traffic. Cybercriminals use botnets to send countless requests that the server can’t handle. This affects the website user experience drastically.
In most cases, a website becomes totally inaccessible to its daily traffic, and this downtime can make a business lose revenue opportunities. To defend against these attacks, traditional cybersecurity solutions aren’t enough. This is why you should acquire cyber security services UAE to keep your website unaffected by these attacks.
