Discuss the technical differences between denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks, including their impact on targets.

Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks are both types of cyberattacks aimed at disrupting the availability of a system, service, or network to its intended users. However, they differ significantly in their technical execution and impact. A DoS attack involves a single source flooding a target with traffic, while a DDoS attack uses multiple sources simultaneously to overwhelm the target. This fundamental difference in attack vector leads to varying levels of severity and complexity in mitigation. A DoS attack is typically launched from a single machine or network connection. The attacker floods the targeted server or network with a high volume of traffic, such as TCP SYN packets, UDP packets, or HTTP requests, intending to exhaust its resources and make it unable to respond to legitimate traffic. For example, a simple TCP SYN flood attack might involve an attacker sending numerous SYN packets to a server, leaving many half-open connections and exhausting the server's resources, preventing it from handling any other new connection. Another type of DoS attack might involve overwhelming a web server with a large number of HTTP GET requests from a single attacker machine. This could make the web server unresponsive to legitimate users. Because the attack source is singular, DoS attacks are usually easier to trace and mitigate, especially with the help of network security devices like firewalls, intrusion det....
