Define Denial of Service attack definition properly. Give a daily life example to understand it more precisely. What are the major symptoms of DoS attacks?
A Denial of Service (DoS) attack is to make a network or machine unavailable to its intended users such as to debar the services of a server connected to internet. When the attack source is more than one, then it is called Distributed Denial of Service attack. A real life example is such as: Suppose a group of people is trying to enter into a shop through a single gate because of which the permissible people are unable to enter, disturbing the normal operations.
The symptoms of DoS attack are:
• Slow network performance (accessing web pages)
• A particular website not available
• Websites not accessible
• Large number of Spam E-mails
• Wired or Wireless connection disabled
• Denial of Access to Internet services for a long time
