Denial of Service

Full Title or Meme

One of the primary STRIDE classes of malicious external attacks.

Context

• Cloud Flare and others provide security support at the edge, like protection from Denial of Service (DoS) attacks.

Problem

What's the threat? Making the system temporarily unavailable or unusable, such as those attacks that could force a reboot or restart of the user's machine. When an attacker can temporarily make the system resources (processing time, storage, etc.) unavailable or unusable, we have a denial of service threat. We must protect against certain types of DoS threats for improved system availability and reliability. However, some types of DoS threats are very hard to protect against, so at a minimum, we must identify and rationalize such threats.
