What is a security policy?

A security policy is fundamentally a document that outlines the measures and protocols an organization employs to protect its data and information systems. This includes detailing the rules and procedures related to risk management, acceptable use of IT resources, access control, data protection measures, and incident response among others.

By clearly defining these elements, a security policy provides a framework for how employees should handle sensitive information and the networks that support it, thus helping to mitigate potential security risks. This structured approach ensures compliance with legal and regulatory requirements, while also fostering a culture of security within the organization.

The other options do not capture the essence of a security policy. Guidelines on work hours pertain to human resources rather than security protocols, tools for network performance analysis focus on optimization rather than protection, and malware removal applications can be part of a security strategy but do not encompass the comprehensive framework and governance offered by a security policy.
