Types of DoS Attack – Different Kinds & Forms Of Denial of Service Attack
While you might know that “DoS attack” stands for Denial of Service attack (or DDoS), it is not the only type of DoS attack. They all have variations, but they can be very different in the way you deal with them.
Different types of DoS attacks
Below are some examples of DoS Attacks.
There are at least two types of DoS attacks. There are three types of DoS attacks: DDoS attacks and unintended DDoS attacks. These are the main characteristics of each.
1. DoS attacks
DoS attacks were a threat to the internet’s first Internet. However, they are now of minimal academic value. DoS attacks are limited to one computer. One computer was sufficient to take down or disable a website in the early day’s internet and dial-up modems. Nowadays, even small hobby websites can absorb DoS attacks without real problems.
2. DDoS attacks
DDoS is Distributed Denial of Service. It’s an updated version of the old-school DoS attacks. There are two main types of DDoS attacks. These include infrastructure-level DDoS attacks (levels 3 and 4 of the OSI 7-layer model) as well as application-level DDoS attacks (levels 6 and 7 of the OSI Seven-layer model).
DDoS attacks at the infrastructure level are similar to old-school DoS attacks, but they affect multiple computers. However, they can be difficult to block if you do a good job monitoring your internet traffic.
DDoS attacks at the application level are, however, much more complex. They require more technical skills to create and more technical skills for resolution. Application-level DDoS attacks attack a specific part of a website. For example, a login page or payment page. They can cause significant traffic disruptions to the website, if not complete downtime. However, they remain undetected for an as long time as possible.
3. DDoS attacks that were not intended
Unintended DDoS attacks occur when legitimate traffic overwhelms a website or a portion of a website to the point that the service is unable to function or even completely shut down. It is often due to media exposure or social media exposure. Perhaps you have seen news stories about celebrities wearing certain items and then the website crashed due to so many people trying to buy them.
Although you may not think of your products or services being used by celebrities, the principle applies regardless. The traffic that results from an unexpected endorsement by someone important to your customer base may feel and look like a DDoS attack.
However, there is one difference between unintended and intended DDoS attacks. The first tend to originate from countries with few or no customers, while the latter is more common in countries that have a large customer base.
DoS attacks on your website can be prevented
Unfortunately, you can’t stop people from attacking you with DDoS attacks. You can reduce their impact if you’re prepared. These are some suggestions.
You can buy as much bandwidth as possible
Your bandwidth is like a pipe. Your pipe is wider, so attackers will have to work harder to flood it. This is the first and most obvious defense you have against DoS attacks.
Make sure to use a website vulnerability scanner and a DDoS mitigation tool.
Although there is plenty of website vulnerability scanner on the market, the core of any decent option is an anti-malware scanner and a web applications firewall. The latter is the most important for DoS attacks. You can also set up your firewall to block as much traffic as possible but still allow you to access the traffic that you desire.
You might consider signing up for a DDoS mitigation program if DDoS attacks are of concern. These services are similar to firewalls but are optimized for DDoS attacks. Firewalls only work when there is a DDoS attack.
Your architecture should be as flexible as possible and as scalable as you can.
This is recommended for many reasons, including protection against DoS attacks. Smart DNS lookup, content distribution networks, load-balancing, and content distribution networks are all important in the context of DoS.
