1. An individual user profile on a social network site is an example of an online identity.

   Answers Explanation & Hints: Online identity refers to the persona or image that an individual presents online through various digital media platforms. It includes information about an individual such as their name, profile picture, personal interests, and activities on social media sites. An online identity can be created through various means, such as creating a user profile on social media sites, blogs, or other online platforms. It can also be shaped by an individual’s interactions with others online, including their comments, likes, and shares. In contrast, an offline identity refers to the persona or image that an individual presents in face-to-face interactions with others. It includes characteristics such as one’s physical appearance, behavior, speech, and other nonverbal cues. An individual’s offline identity is shaped by their upbringing, education, cultural background, and life experiences. Therefore, an individual user profile on a social network site is an example of an online identity, as it represents the digital persona that an individual presents online.

2. Cybersecurity is the ongoing effort to protect individuals, organizations and governments from digital attacks by protecting networked systems and data from unauthorized use or harm.

   What level of cyber protection does each of the following factors require?

   • Your online identity
     Personal
   • A customer database
     Organizational
   • Economic stabilty
     Government

     Answers Explanation & Hints: Your online identity: The level of cyber protection required for an online identity depends on the context and the individual’s perception of risk. For personal online identities, individuals need to take proactive steps to protect their accounts, such as creating strong passwords, enabling two-factor authentication, and avoiding phishing scams. Organizations also need to provide cybersecurity training to their employees and implement measures such as firewalls and intrusion detection systems to protect online identities of their employees and customers. Therefore, both Personal and Organization levels require cyber protection for online identity. A customer database: A customer database contains sensitive information such as names, addresses, phone numbers, and payment details, and is a prime target for cybercriminals. Therefore, both Personal and Organization levels require cyber protection for customer databases. Organizations need to implement strict access controls, use encryption to protect data in transit and at rest, and regularly monitor their systems for suspicious activity. Governments also need to enforce regulations to ensure that organizations handling sensitive customer data are taking appropriate cybersecurity measures. Economic stability: Economic stability is crucial for both governments and organizations, as it affects the overall prosperity of a country or industry. Cyberattacks can disrupt the financial system and cause economic instability. Therefore, the Government level requires cyber protection for economic stability. Governments need to develop and enforce regulations and standards for cybersecurity in critical infrastructure sectors such as finance and energy, and collaborate with other nations to combat cybercrime. Organizations also need to implement cybersecurity measures to protect their financial systems, but the level of protection required may vary depending on the sector and the organization’s size and complexity.

3. Which of the following pieces of information would be classified as personal data?

   Select three correct answers

   • Social security number
   • Driver license number
   • Date and place of birth
   • Job title
   • IP address
     

     Answers Explanation & Hints: The three pieces of information that would be classified as personal data are: Social security number Driver license number Date and place of birth The social security number and driver license number are government-issued identification numbers that are unique to an individual, and therefore, are considered highly sensitive personal data. The date and place of birth can also be used to identify an individual and may be used in combination with other information to steal someone’s identity or perpetrate other types of fraud. Job title and IP address are not necessarily considered personal data on their own, as they are more general pieces of information that do not uniquely identify an individual. However, they may be considered personal data in certain contexts, such as when an IP address is linked to other identifying information or when a job title is used to infer other personal characteristics.

4. Your neighbor tells you that they don’t have an online identity. They have no social media accounts and only use the Internet to browse. Is your neighbor right?

   • Yes
   • No
     

     Answers Explanation & Hints: No, your neighbor is not entirely correct. Even if they do not have any social media accounts, their online activities can still create a digital footprint, which is a collection of data generated by an individual’s online activities. For instance, whenever they use the internet to browse, their IP address and other browsing data are collected by websites and internet service providers. Moreover, they may have online accounts, such as email or banking, which also contribute to their online identity. Therefore, even if your neighbor is not actively maintaining an online presence, they still have an online identity to some extent.

5. What are the foundational principles for protecting information systems as outlined in the McCumber Cube?

   Choose three correct answers

   • Access
   • Integrity
   • Scalability
   • Availability
   • Confidentiality
   • Intervention
     

     Answers Explanation & Hints: The foundational principles for protecting information systems as outlined in the McCumber Cube are: Confidentiality Integrity Availability Confidentiality refers to the protection of information from unauthorized disclosure or access. It ensures that sensitive information is only accessed by authorized individuals and is not disclosed to unauthorized parties. Integrity refers to the protection of information from unauthorized modification or destruction. It ensures that information is accurate, complete, and trustworthy. Availability refers to the protection of information systems and data from unauthorized disruption or denial of service. It ensures that information and systems are available to authorized users when needed. Scalability and Intervention are not foundational principles outlined in the McCumber Cube. Scalability refers to the ability of a system to adapt to changing demands, and intervention refers to the process of taking action to prevent or mitigate security incidents. While important, these concepts are not considered foundational principles in the McCumber Cube.

6. Which of the following methods can be used to ensure confidentiality of information?

   Choose three correct answers

   • Backup
   • Version control
   • Data encryption
   • File permission settings
   • Two-factor authentication
   • Username ID and password
     

     Answers Explanation & Hints: The three methods that can be used to ensure confidentiality of information are: Data encryption Two-factor authentication Username ID and password Data encryption involves encoding information in a way that makes it unreadable to anyone who does not have the decryption key. This helps ensure that sensitive information remains confidential, even if it falls into the wrong hands. Two-factor authentication adds an additional layer of security to login procedures, requiring users to provide a second factor (such as a code sent to their mobile phone) in addition to their username and password. This helps prevent unauthorized access to sensitive information, even if an attacker manages to obtain a user’s login credentials. Username ID and password is a correct method to ensure confidentiality of information. By requiring a username and password to access sensitive information or systems, it limits access to only those who have been granted permission and provides a layer of authentication to verify the identity of the user. This helps to prevent unauthorized access and protect the confidentiality of the information.

7. Which of the following is a key motivation of a white hat attacker?

   • Taking advantage of any vulnerability for illegal personal gain
   • Fine tuning network devices to improve their performance and efficiency
   • Studying operating systems of various platforms to develop a new system
   • Discovering weaknesses of networks and systems to improve the security level of these systems
     

     Answers Explanation & Hints: The key motivation of a white hat attacker is discovering weaknesses of networks and systems to improve the security level of these systems. White hat attackers are ethical hackers who use their skills and knowledge to identify vulnerabilities in systems and networks with the goal of helping organizations improve their security defenses. Unlike black hat attackers, who engage in malicious activities for personal gain, white hat attackers are motivated by a desire to improve cybersecurity and prevent cybercrime. They work closely with organizations to identify and fix vulnerabilities before they can be exploited by malicious actors.

8. Why might internal security threats cause greater damage to an organization than external security threats?

   • Internal users have better hacking skills
   • Internal users have direct access to the infrastructure devices
   • Internal users can access the organizational data without authentication
   • Internal users can access the infrastructure devices through the Internet
     

     Answers Explanation & Hints: Internal security threats can cause greater damage to an organization than external security threats because internal users have direct access to the organization’s infrastructure devices and data. Unlike external attackers who need to bypass security measures to gain access to sensitive data, internal users already have authorized access to the organization’s systems and data. This makes it easier for them to carry out malicious activities, such as stealing confidential data, modifying or destroying data, or disrupting critical systems. Additionally, internal users may have a better understanding of the organization’s systems and may be able to exploit vulnerabilities more effectively than external attackers. Overall, internal security threats can be more difficult to detect and mitigate, making them a greater risk to organizational security.
