This type of attack uses large amounts of Internet Control Message Protocol (ICMP) ping traffic target at an Internet Broadcast Address. Since the sent data packages are larger than what the server can handle, the server can freeze, reboot, or crash. TCP/IP fragmentation breaks the packets into small chunks that are sent to the server. The ping of death takes advantage of this and sends data packets above the maximum limit (65,536 bytes) that TCP/IP allows. It works by sending small data packets to the network resource. The ping command is usually used to test the availability of a network resource. We will look at five common types of attacks. Let’s look at how DoS attacks are performed and the techniques used. Distributed DoS– this type of attack is performed by a number of compromised machines that all target the same victim.DoS– this type of attack is performed by a single host.There are two types of Dos attacks namely In this tutorial, we will introduce you to what denial of service attack is, how it is performed and how you can protect against such attacks. Some organizations such as payment gateways, e-commerce sites entirely depend on the internet to do business. The internet and computer networks power a lot of businesses. The effect of this can either be crashing the servers or slowing them down.Ĭutting off some business from the internet can lead to significant loss of business or money.

This results in the server failing to respond to all the requests. This type of attack is usually implemented by hitting the target resource such as a web server with too many requests at the same time.

DoS is the acronym for Denial of Service. DOS is an attack used to deny legitimate users access to a resource such as accessing a website, network, emails, etc.
