220.127.116.11 describe data protection measures such as encryption and access rights to data (authorisation)
Access rights to data
Data protection measures are processes and procedures put in place to ensure the confidentiality, integrity, and availability of data.
Data access rights refer to the permissions granted to users or groups to access specific data. These permissions can be managed through access control mechanisms, such as user authentication, authorization, and auditing.
The first step in protecting data is to identify which users or groups require access to the data. Access rights can then be granted based on the principle of least privilege, where users are granted only the minimum access necessary to perform their job functions. This reduces the risk of unauthorized access to sensitive data.
Access rights can also be customized based on user roles and responsibilities. For example, a manager may have access to more data than a lower-level employee.
Furthermore, access rights can be controlled at different levels, including the file, folder, and system levels. Access controls can also be applied to different types of data, such as read-only access, modify access, or delete access.
In addition to access control mechanisms, data protection measures can include other security measures such as encryption, data backups, and monitoring of access logs to detect any unauthorized access attempts. These measures work together to protect data from theft, loss, or corruption.
Exercise 1: You are a security analyst at a financial institution. Your team has identified several sensitive files that need to be protected. Design an access control model to manage access rights to these files, and explain how the model would prevent unauthorized access. (10-15 sentences)
Exercise 2: Consider the following scenario: An employee accidentally sends an email containing sensitive customer information to an unauthorized recipient. Explain how encryption could have prevented this data breach, and what measures could be taken to prevent similar incidents from occurring in the future. (10-15 sentences)
Exercise 3: Your organization has implemented access controls to protect sensitive data. However, you suspect that an employee may be abusing their access rights to view data they are not authorized to access. What steps would you take to investigate this potential breach, and what measures could be implemented to prevent similar incidents in the future? (10-15 sentences)
Question 1: Explain the importance of access control for data protection. Provide examples of access control mechanisms and their role in managing access rights to data. (10 marks)
Question 2: Discuss the potential risks of unauthorized access to sensitive data and how organizations can mitigate these risks. (15 marks)
