Lesson 4 DDOS and Bots

Trinity hacks into HMRC His Majestic Revenue Service database. She finds several vulnerabilities which she reports to the site owner. She hopes they will offer her a reward for the information. What type of hacking is this?

• White hat hacking

• Black hat hacking

• Grey hat hacking

• Script kiddie

Trinity hacks into HMRC His Majestic Revenue Service database. She finds several vulnerabilities which she reports to the site owner. She hopes they will offer her a reward for the information. Is it ethical?

• No, it is not ethical because hacking is illegal.

• It depends on the intention behind the hacking.

• It is ethical if she gets permission afterwards.

Trinity hacks into HMRC His Majestic Revenue Service database. She finds several vulnerabilities which she reports to the site owner. She hopes they will offer her a reward for the information. Is it legal?

• Yes, it is legal to hack into databases if vulnerabilities are reported.

• No, it is illegal to hack into databases regardless of intentions.

• It depends on the country's laws regarding ethical hacking.

• Only if she receives a reward, it becomes legal.

What do you think would happen if servers suddenly had billions of requests per second?

• Responses would become very slow

• System may crash

• Service would become unavailable

Why would someone wish to make a system unavailable to others? Think how someone, an organisation, or country might benefit.

• To gain a competitive advantage

• To protect sensitive information

• To disrupt an opponent's operations

• All of the above

What is meant by a client-server relationship?

• A relationship where both parties are equal

• A relationship where the client requests services and the server provides them

• A relationship where the server requests services and the client provides them

• A relationship where neither party requests or provides services

In a DoS attack, what is the primary action taken by the attacker?

• The attacker sends a large number of requests to overwhelm the server.

• The attacker steals sensitive data from the server.

• The attacker installs malware on the server.

• The attacker gains unauthorized access to the server.

Which of the following are motivations for a DoS attack?

• Financial gain and disruption of services

• Improving network security and performance

• Enhancing user experience and satisfaction

• Reducing server load and maintenance costs

What is meant by a client-server relationship?

• A type of network architecture where a server provides resources or services, and a client accesses them.

• A relationship between two clients in a peer-to-peer network.

• A type of relationship in a database management system.

• A relationship between two servers in a distributed network.

In a DoS attack, what typically happens?

• A single computer is used to flood a network with traffic, causing it to become unavailable.

• Multiple computers are used to flood a network with traffic, causing it to become unavailable.

• A network is monitored for vulnerabilities without causing disruption.

• A network is protected from unauthorized access.
