What is a security policy?

A security policy serves as a formal document that outlines an organization's security practices, principles, and guidelines. It provides a framework for managing and protecting sensitive information and assets against various threats and vulnerabilities. By establishing clear security protocols and responsibilities, a well-defined security policy helps ensure that all employees understand their role in maintaining the organization's security posture. This document typically includes information on acceptable use, access controls, data protection, incident response, and compliance requirements. The clarity and thoroughness of a security policy are critical for fostering a culture of security within the organization and minimizing risks associated with security breaches.

In contrast, the other options do not encapsulate the essence or purpose of a security policy. Software installation guidelines focus on technical aspects rather than the comprehensive security approach a policy provides. A technical manual would be aimed at engineers and does not address broader organizational security issues. A list of company employees does not relate to security practice; it fails to provide any context or framework for managing security-related issues and responsibilities.
