Which of the following security policy types is LEAST common?

A parking policy typically outlines the parking arrangements for both employees and visitors, including the criteria and procedures for assigning parking spaces to employees. This policy is not part of an organization's security policy but rather an operational or business policy. An acceptable use policy, on the other hand, outlines guidelines and limits for users regarding the use of an organization's physical and intellectual resources, such as the use of personal email during work hours. A social media policy defines how employees should use social media networks and applications, such as Facebook, Twitter, and LinkedIn, among others, as it can impact a company's reputation. Password policies, on the other hand, define the complexity of password creation, identify weak passwords, and outline how users should protect their password safety.
