Cambridge Technicals Cyber Security Quiz

Evie, Anaya, and Aarav are working on a school project about cyber security. They are discussing the purpose of network security in this context. According to their research, what is the main purpose of network security in the context of cyber security?

• To allow unrestricted access to all data and resources

• To make the network run faster

• To protect the integrity, confidentiality, and availability of data and resources on a network.

• To increase the risk of data breaches

Jacob, Alexander, and Chloe are discussing network security. Jacob explains that a firewall is like a security guard for a network, but Chloe and Alexander are confused. Can you clarify what a firewall is in the context of network security?

• A firewall is like a physical wall built around a network, similar to a fortress, to prevent unauthorized access.

• A firewall is a network security device that monitors and controls incoming and outgoing network traffic, much like a security guard checking people's credentials at a building entrance.

• A firewall is a software that protects a computer from viruses and malware, similar to an antivirus program.

• A firewall is a device that amplifies network signals to improve internet speed, like a signal booster.

Isabelle, Kiara, and Priya are working on a project for their cyber security class. They need to protect their project data from unauthorized access. What is data encryption and why is it important for their project?

• Data encryption is the process of deleting data to prevent unauthorized access. It is important for their project to reduce the amount of data stored.

• Data encryption is the process of converting data into a code to prevent unauthorized access. It is important for their project to protect sensitive information from being accessed by hackers or unauthorized users.

• Data encryption is the process of converting data into a physical form to make it easier to access. It is important for their project to make data more accessible to authorized users.

• Data encryption is the process of converting data into a code that is easily decipherable. It is important for their project to make data more vulnerable to hackers.

Freya, Arjun, and Daniel are working on a project to secure their company's data. They decide to use the AES algorithm. Describe the process they would follow to encrypt the data using the AES algorithm.

• They would convert the data into binary code and then apply a simple substitution cipher.

• They would compress the data and then apply a basic XOR operation with a secret key.

• They would follow a process that involves key expansion, initial round key addition, multiple rounds of substitution, permutation, and mixing of data, and final round of substitution and permutation.

• They would convert the data into hexadecimal format and then apply a simple transposition cipher.

Emily, Sophia, and Leo are working in a tech company. They are discussing how to prevent cyber attacks in their company. What are some common methods they could suggest?

• Using weak passwords

• Leaving software outdated

• Not implementing any security protocols

• Using strong passwords, keeping software updated, using firewalls and antivirus software, implementing security protocols, and educating employees about cyber security best practices.

Benjamin received an email from an unknown source asking for his personal information. Noah suggested him to click on the link provided in the email. Matilda, on the other hand, advised him to be cautious of such unsolicited emails, not to click on suspicious links, and to use security software. What should Benjamin do to prevent phishing?

• Be cautious of unsolicited emails, not clicking on suspicious links, and using security software.

• Click on all links in unsolicited emails

• Share personal information with unknown sources

• Disable security software

Harry, Lily, and Noah are part of the IT department in a large organization. They are discussing the importance of security policies in their organization. What is their consensus?

• Harry thinks that security policies are only necessary for IT departments, not other areas of the organization

• Lily believes that security policies are only important for large organizations, not small ones

• Noah argues that security policies are a waste of time and resources in an organization

• They all agree that security policies are a set of rules and guidelines that outline the organization's approach to security. They are important in an organization to ensure the protection of sensitive information, compliance with regulations, and the prevention of security breaches.

Emily, Ishaan, and George are working on a group project. They are using a shared online workspace. Discuss the role of access control in this scenario in enforcing security policies.

• Regulating who among Emily, Ishaan, and George can access certain project files and what actions they can perform

• Ignoring security policies and regulations in the shared workspace

• Allowing Emily, Ishaan, and George unlimited access to all project files

• Granting access to the project files to unauthorized users

Max, Priya, and Isla are part of a cyber security team at a large corporation. Why is their role in incident response important?

• They create security incidents to test the system's resilience

• Their role in incident response is not important

• They ignore security incidents

• They respond to and manage security incidents to limit damage and reduce recovery time. This is crucial to minimize the impact of security breaches and protect the corporation's sensitive information.

Arjun, Kiara, and Oscar are part of a cybersecurity team at a large corporation. A security breach occurs in their system. Outline the steps they should take in response to this incident.

• Ignore the breach and hope it goes away

• Preparation, identification, containment, eradication, recovery, and lessons learned

• Blame someone else for the breach

• Delete all evidence of the breach
