DoS attacks result in a multitude of consequences. Let’s look at some common examples of what is seen in the real world, and what you’ll most likely see on the exam:
Web Server Compromise A successful DoS attack and subsequent compromise of a web server constitutes the widest public exposure against a specific target. What you see most often is a loss of uptime for a company web page or web resource.
Back-end Resources Back-end resources include infrastructure items that support a public-facing resource such as a web page. DoS attacks that take down a back-end resource such as a customer database or server farm essentially render all front-end resources unavailable.
Network or Computer Specific DoS attacks are also launched from within a local area network, with intent to compromise the network itself, or to compromise a specific node such as a server or client system.
