What is the goal of a Denial-of-Service (DoS) attack?
What is the goal of a Denial-of-Service (DoS) attack?
- To perform network maintenance
- To steal sensitive information from a network
- To gain unauthorized access to a network
- To disrupt the availability of a network (correct)
How can an attacker successfully launch a Distributed Denial-of-Service (DDoS) attack?
How can an attacker successfully launch a Distributed Denial-of-Service (DDoS) attack?
- By sending lots of packets to the victim's network (correct)
- By using a single compromised machine to overload the victim's network
- By launching targeted phishing attacks
- By checking if the packets originate from the same source IP address
