Which of the following are the important areas addressed by a software system's security policy? Each correct answer represents a complete solution. Choose all that apply.

Identification and authentication are crucial for a security policy to ensure that only legitimate users and processes can access the system, verifying who they are before granting entry.

Punctuality, while important for project management or service delivery, is not a direct security policy area for a software system.

Data protection is a core concern for security policies, addressing how information is safeguarded from unauthorized access, modification, or destruction throughout its lifecycle.

Accountability ensures that actions within the system can be traced back to an individual or process, which is essential for auditing, incident response, and enforcing policy compliance.

Scalability refers to a system's ability to handle increased load or growth, which is a performance and architecture concern, not a primary area of a security policy.

Access control dictates which users and processes can access specific resources and what operations they can perform, directly implementing the 'who can do what' rules defined by the security policy.
