DDos attacks

What does DDoS stand for?

• Distributed Denial of Service

• Dangerous Data of Service

• Data Delivery Of Service

• Direct Deployment of Servers

Answer explanation

DDoS stands for Distributed Denial of Service, which refers to a cyber attack that overwhelms a target system with a flood of internet traffic, rendering it inaccessible to users.

What is the primary goal of a DDoS attack?

• To improve network performance

• To steal sensitive information

• To overwhelm a target system or network

• To test system vulnerabilities

Answer explanation

The primary goal of a DDoS attack is to overwhelm a target system or network, causing it to become unavailable to users.

Which type of traffic is typically used in a volume-based DDoS attack?

• ICMP

• HTTP

• TCP

• UDP

Answer explanation

In a volume-based DDoS attack, UDP traffic is commonly used due to its connectionless nature and ability to flood the target with a high volume of packets.

What is the main purpose of a botnet in a DDoS attack?

• To generate a large amount of traffic or requests to overwhelm a target server or network

• To improve the performance of the target server or network

• To gather information about the target server or network

• To protect the target server or network from attacks

Answer explanation

The main purpose of a botnet in a DDoS attack is to generate a large amount of traffic or requests to overwhelm a target server or network.

Which type of DDoS attack targets a server's resources by exploiting vulnerabilities in network protocols?

• network-based DDoS attack

• application-based DDoS attack

• vulnerability-based DDoS attack

• protocol-based DDoS attack

Answer explanation

A protocol-based DDoS attack targets a server's resources by exploiting vulnerabilities in network protocols.

In a reflection and amplification attack, what does the attacker spoof?

• destination IP address

• MAC address

• DNS server

• source IP address

Answer explanation

In a reflection and amplification attack, the attacker spoofs the source IP address to hide their identity and make it appear as if the attack is coming from a different source.

What are the potential consequences for individuals who launch DDoS attacks?

• No consequences, enhanced cybersecurity skills, increased job opportunities

• Financial gain, increased internet speed, improved reputation

• Legal consequences, damage to reputation, loss of internet access, civil lawsuits

• Community recognition, improved internet security, legal protection

Answer explanation

Individuals who launch DDoS attacks may face legal consequences, reputation damage, loss of internet access, and civil lawsuits.

How do organizations typically defend against DDoS attacks?

• Implementing various strategies such as traffic filtering, rate limiting, load balancing, and using DDoS mitigation services.

• Increasing network bandwidth

• Blocking all incoming traffic

• Installing antivirus software

Answer explanation

Organizations defend against DDoS attacks by implementing strategies like traffic filtering, rate limiting, load balancing, and using DDoS mitigation services.
