Discussion 1 - Week 2

Internet Vulnerabilities

The Internet relies on the domain name system (DNS) to translate a domain name to an IP address. This along with the structure and routing of IP packets rely on cooperation among independently managed network components.

Utilize the Walden University Library websites devoted to Internet security and computer emergency readiness, and other resources to locate an article describing a specific IP weakness or vulnerability. The article should be a reliable source and no more than four years old. You might consider packet sniffing, denial of service attacks, spoofing, cache poisoning, or hijacking.

Post to this Discussion, a summary of the article in which you:

Describe the vulnerability

Explain how the IP and DNS structure allows that vulnerability

Describe strategies for identifying that an attack has taken place exploiting that vulnerability

Describe what reasonable steps might be taken to prevent this form of attack
