How does Authorized Access Control limit system access based on process?

1. Access is granted only to all processes

2. Access is denied for all processes

3. Access is limited to processes acting on behalf of authorized users

4. Access is unlimited for authorized processes

The correct answer is: Access is limited to processes acting on behalf of authorized users

Authorized Access Control is a foundational principle in cybersecurity that focuses on ensuring that only designated individuals or processes have the right to access specific resources within a system. The correct choice highlights that access is specifically limited to processes that are acting on behalf of authorized users. This means that the system checks and verifies the identity of the user or process attempting to gain access, ensuring that only those who have been granted specific permissions are able to execute functions or access data. This mechanism is essential for upholding the integrity and confidentiality of information. By allowing access only to processes that are properly authenticated and authorized, the system effectively minimizes the risk of unauthorized or malicious activities, thereby protecting sensitive data from potential breaches or misuse. This specific focus on authorized processes reflects the core principle of least privilege, which aims to give users and processes the minimum access necessary to perform their functions. Access is not granted freely to all processes—this would expose the system to a high level of risk, as any process could potentially perform harmful actions. Similarly, outright denial for all processes would render the system unusable. Finally, providing unlimited access to authorized processes without any restrictions would compromise the security posture, as it could lead to excessive permissions that may inadvertently enable unauthorized access. Thus, the answer emphasizes a controlled
