What is the purpose of a security policy in an organization?

The purpose of a security policy in an organization is to define the rules and practices that are essential for protecting the organization's information systems. This policy serves as a formal document that outlines the security requirements and the measures that must be taken to safeguard the confidentiality, integrity, and availability of information.

A well-structured security policy typically covers various aspects such as data protection, acceptable use of resources, incident response protocols, and compliance with relevant regulations. It provides a framework for decision-making and helps to communicate the security expectations to all employees, thereby fostering a culture of security awareness within the organization.

While other choices touch on important aspects of an organization's operations, they do not specifically address the comprehensive approach that a security policy takes in protecting information systems. Hardware requirements, employee training on software usage, and the responsibilities of IT team members are valuable but are secondary components that may be governed by the overarching security policy itself.
