Threats: Denial of Service

Introduction

Hi, I'm Luca and I am a student in year 10 at St. Francis Xavier's College in Woolton, Liverpool. One of the subjects I am currently studying at school is ICT, and I am going to share my knowledge and understanding of this subject with everyone in a series of blogs. In this particular blog, I will be discussing cyber bullying. I hope that you enjoy this blog, and come away learning something new which you can hopefully pass on to someone else.

What is Denial of Service
Denial of Service is an illegal act, which has the intent of disabling a server.

Every server responds to external requests from its network. An example of this is when a web server responds to an internet browser calling for a web page to be delivered from its hard drive.

Each request takes a small period of time and some of the CPU resources on a server. With a DoS attack, the server is overwhelmed by millions of rogue requests being sent to it. This means that it is using up all of its resources and denying normal service for the legitimate users.

Why Would these Types of Attack be Made

A reason why these types of attacks would be made is because if one person has access to the wire that someone else is using, they then have access to that person's computer. This means that the person who is being granted access can find out all different types of information, such as bank details, passwords, internet history and a lot more.
