Access Control Measures

Sample Solution

   

I am a security engineer at a large financial institution. Our institution has a large database of customer information, including account balances, transaction history, and personal data. This information is highly sensitive and must be protected from unauthorized access.

I would use discretionary access control (DAC) to protect this information. DAC allows me to specify who has access to what resources and what actions they are allowed to perform on those resources. This gives me the flexibility to implement granular access controls that are tailored to the specific needs of my organization

    For example, I could create different user groups for different types of employees. For example, customer service representatives might only need access to customer contact information and account balances. Financial analysts might need access to transaction history and other financial data. And only senior management might need access to all of the data. I could also use DAC to restrict access to specific resources. For example, I could create a separate database for sensitive customer information and restrict access to that database to a small group of trusted employees. Why DAC? I chose DAC over other access control measures because it gives me the flexibility to implement granular access controls that are tailored to the specific needs of my organization. DAC is also relatively easy to implement and manage. Other access control measures, such as mandatory access control (MAC) and role-based access control (RBAC), can be more difficult to implement and manage. MAC is also less flexible than DAC, as it does not allow me to specify who has access to what resources and what actions they are allowed to perform on those resources. Mandatory vacation as a tool to detect fraud and help employees release their work stress: Mandatory vacation can be used as a tool to detect fraud and help employees release their work stress in a number of ways. Detecting fraud: Fraudsters often try to cover their tracks by taking advantage of gaps in access control. For example, a fraudster might try to log into a system during a time when there is no one else around to notice. Mandatory vacation can help to detect fraud by making it more difficult for fraudsters to cover their tracks. If all employees are required to take a certain amount of vacation each year, it will be more difficult for a fraudster to hide their activities for a long period of time. Helping employees release work stress: Employees who are stressed are more likely to make mistakes. This can lead to errors in judgment, which can be exploited by fraudsters. Mandatory vacation can help employees to release their work stress and make better decisions. When employees are well-rested, they are better able to focus and concentrate. They are also less likely to make mistakes. Conclusion Access control is an important security measure that can be used to protect data from unauthorized access. Discretionary access control (DAC) is a flexible and easy-to-implement access control measure that can be used to protect a variety of resources. Mandatory vacation can be used as a tool to detect fraud and help employees release their work stress. Mandatory vacation can make it more difficult for fraudsters to cover their tracks and can help employees to make better decisions.
