Many organizations offer a free domain name resolution service that resolves DNS requests through a worldwide network of redundant DNS servers. The claim is that this is faster and more reliable than using the DNS servers provided by Internet Service Providers (ISP). They also claim that their DNS servers improve security by maintaining a real-time blacklist of harmful websites and will warn users whenever they attempt to access a site containing potentially threatening content. They also say that using this service can reduce exposure to types of DNS poisoning attacks. Research free DNS services. Identify at least three providers and create a table comparing their features. Are the claims of providing improved security valid? How do they compare with your ISP's DNS service?
Now consider how the denial of service (DoS) attacks can cripple an organization that relies heavily on its web application servers, such as online retailers. What are some of the most widely publicized DoS attacks that have occurred recently? Who was the target? How many DoS attacks occur on a regular basis? What are some ways in which DoS attacks can be prevented?
Write at least a paper of your research on DoS Attacks, and make sure to include the table created for the DNS.
