Question 1: Briefly define each of the three members of the information security triad.
The information security triad comprises confidentiality, integrity, and availability. Confidentiality ensures that sensitive data is accessible only to authorized individuals and prevents unauthorized disclosure (Whitman & Mattord, 2022). Integrity involves maintaining the accuracy and consistency of data over its lifecycle, preventing unauthorized modifications (Stallings, 2020). Availability guarantees that information and resources are accessible to authorized users when needed, minimizing downtime and service disruptions (Paller et al., 2018).
Question 2: What does the term authentication mean?
Authentication is the process of verifying the identity of a user, device, or entity attempting to access a system or resource. It confirms that the user is who they claim to be, typically through credentials such as passwords, biometric data, or tokens (O’Gorman, 2021).
Question 3: What is multi-factor authentication?
Multi-factor authentication (MFA) requires users to provide two or more different types of credentials from separate categories to verify their identity. These categories include something you know (password), something you have (smart card or phone), and something you are (biometric data). MFA significantly enhances security by reducing the risk of unauthorized access due to compromised credentials (Das & Iyer, 2019).
Question 4: What is role-based access control?
Role-based access control (RBAC) is a method of restricting system access based on the roles assigned to users within an organization. Each role has specific permissions, and users acquire permissions through their roles, simplifying management and enforcing security policies effectively (Sandhu et al., 1996).
Question 5: What is the purpose of encryption?
The purpose of encryption is to protect data by converting it into a coded form that is unreadable without a decryption key. Encryption ensures confidentiality and integrity during data transmission and storage, preventing unauthorized access and interception (Stallings, 2020).
Question 6: What are two good examples of a complex password?
Two examples of complex passwords are: pX7#9kL!mQ2 and R3v&t9B*4wA!. These passwords incorporate a mix of uppercase and lowercase letters, numbers, and special characters, which make them difficult for attackers to guess or crack (Snyder & Schartner, 2019).
Question 7: What is pretexting?
Pretexting is a form of social engineering where an attacker creates a fabricated scenario or pretext to obtain sensitive information from someone. The attacker manipulates the target into revealing confidential data by pretending to have a legitimate reason or authority (Mitnick & Simon, 2002).
Question 8: What are the components of a good backup plan?
A good backup plan includes regular and scheduled backups, secure storage of backup copies, verification of backup data, off-site storage, and a clear recovery procedure. These components ensure data durability and quick recovery in case of data loss or system failure (Nelson, Phillips, & Steuart, 2018).
Question 9: What is a firewall?
A firewall is a security device or software that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its primary function is to establish a barrier between a trusted internal network and untrusted external networks, such as the internet (Pfleeger & Pfleeger, 2015).
Question 10: What does the term physical security mean?
Physical security involves protecting an organization’s physical assets, such as hardware, facilities, and personnel, from harm, theft, or unauthorized access. It includes security measures like surveillance cameras, security guards, locks, and access controls (Miller & Valacich, 2018).
Exercise
Exercise 1: Find favorable and unfavorable articles about both blockchain and bitcoin. Report your findings, then state your own opinion about these technologies.
Articles reporting on blockchain technology highlight its potential to revolutionize industries by providing transparent, secure, and decentralized transactions, reducing fraud, and increasing efficiency. Favorable articles emphasize its application in supply chain management, finance, and voting systems (Tapscott & Tapscott, 2016). Conversely, unfavorable articles often focus on security vulnerabilities, regulatory challenges, and the environmental impact of cryptocurrency mining using blockchain, notably Bitcoin. Critics argue that the energy consumption and scalability issues hinder widespread adoption (Bonneau et al., 2015). In my opinion, blockchain holds transformative potential if integrated thoughtfully, but its limitations and risks must be addressed through technological improvements and regulatory frameworks.
Exercise 2: Find the information security policy at your place of employment or study. Is it a good policy? Does it meet the standards outlined in the chapter?
At my institution, the information security policy covers data protection, user responsibility, incident reporting, and access controls. It provides clear guidelines and roles, aligning well with recommended standards, such as regular audits and employee training. Its comprehensiveness and enforceability suggest it is a strong policy, although ongoing updates are essential to address emerging threats (ISO/IEC 27001, 2013).
Exercise 3: How diligent are you in keeping your own information secure?
I actively follow security best practices, such as using strong, unique passwords, enabling multi-factor authentication, and being cautious with sharing personal information online. I regularly update my software and educate myself on emerging security threats, which enhances my overall information security awareness and practices (Anderson et al., 2019).
