Denial of Service

Angie Azzi

A denial-of-service, or DOS, attack is an attempt to disrupt or shut down the normal functioning of a targeted server, service, or network by overwhelming it with a flood of illegitimate requests that trigger a crash. This causes the target to become slow, unresponsive, or utterly inaccessible to legitimate users. These malicious endeavors can cripple websites, disrupt services, and cause significant financial and reputational damage.

In the google 2017 DoS attack, Google reported a significant Distributed Denial of Service attack, which was the largest recorded at the time. The attack peaked at 2.54 terabits per second (Tbps) and targeted Google's services. The company emphasized its robust defenses that helped mitigate the attack.

Both cases involved DoS attacks aimed at major technology companies, with the intent to disrupt their services. Each incident was noted for its unprecedented scale at the time of reporting, showcasing the growing threats of DoS attacks in the tech industry. Both Google and Amazon emphasized their security measures and capabilities to withstand and mitigate these attacks effectively. However, the Google attack focused on its broader services, while the Amazon attack specifically targeted Amazon Web Services. The Amazon attack was larger, peaking at 3.5 Tbps compared to Google's 2.54 Tbps. The Amazon incident was also more recent than the Google.

In the "Build a Network" activity, one person would be giving multiple strings to one other participant to overwhelm them. This would trigger a crash and causes the other participant to be slow and unresponsive.
