Unit 3 - 2.4.8 DoS & DDoS

What is the primary goal of a Denial of Service (DoS) attack?

• To intercept communication by tapping into network cables.

• To manipulate computer hardware to compromise its integrity.

• To disrupt the availability of a service or information.

• To manipulate individuals into divulging confidential information.

What type of DoS attack can be inadvertently caused by improper configuration, leading to a broadcast storm?

• Reflected DDoS attack

• Amplified DDoS attack

• On-Path Attack

• Switching Loop

What is a Distributed Denial of Service (DDoS) attack characterized by?

• Multiple agents attacking a single system.

• A single agent attacking multiple systems.

• Flooding a server with SYN packets.

• Exploiting servers or systems to amplify attack traffic.

What is the primary difference between a network DDoS attack and an application DDoS attack?

• Network DDoS attacks target physical machines connected to the network.

• Application DDoS attacks exploit vulnerabilities in network protocols.

• Network DDoS attacks target an entire network to shut it down.

• Application DDoS attacks slow down or render specific applications useless.

What is an amplified DDoS attack?

• Exploiting servers to reflect attack traffic towards the target.

• Flooding a server with SYN packets to bog down network resources.

• Spreading agents across various systems to create a distributed attack.

• Leveraging servers to generate a significantly larger response to a small request.

How do reflected DDoS attacks work?

• Exploit servers to reflect attack traffic towards the target.

• Attack multiple systems simultaneously.

• Flood a server with SYN packets to bog down network resources.

• Utilize agents to amplify traffic directed at the target.

What is the key defense measure against DDoS attacks mentioned in the text?

• Implementing insecure protocols like ICMP and UDP.

• Using experimental and signature-based IDS/IPS for security monitoring.

• Increasing the number of public-facing servers.

• Configuring systems to allow for improper equipment usage.

What is the main goal of a network DDoS attack?

• To shut down specific applications.

• To slow down network traffic.

• To disrupt an entire network.

• To exploit vulnerabilities in network protocols.

What is the primary difference between DoS and DDoS attacks?

• DoS attacks exploit insecure protocols.

• DDoS attacks utilize multiple agents to amplify traffic.

• DoS attacks target physical machines connected to the network.

• DDoS attacks involve flooding a server with SYN packets.

What can inadvertently cause a Denial of Service attack, as mentioned in the text?

• Improper system load balancing.

• Proper security monitoring using IDS/IPS.

• Configuring systems to use secure protocols like TCP.

• Inadequate bandwidth for the environment.
