  • The organization wants to implement this policy for all of the IT assets it owns and to incorporate this policy review into its annual security awareness training program.
  • The organization wants to define a policy framework, including a security management policy defining the separation of duties related to information systems security.
  1. Use the following template to create your security management policy as it relates to separation of duties for the ABC Bank (this should be no more than 3 pages).

ABC Bank

Policy Name

Policy Statement

{Insert policy statement here}

Purpose/Objectives

{Insert the policy’s purpose as well as its objectives; include a bulleted list of the policy definitions.}

Scope

{Define whom this policy applies to and the scope that it covers. Which of the seven domains of a typical IT infrastructure are impacted? All seven should be included in the scope.

What elements, IT assets, or organization-owned assets are within this policy’s scope? In this case, you are concerned about which IT assets and elements in each of the domains require information systems security management.}

Standards

{Does the policy statement point to any hardware, software, or configuration standards? If so, list them here and explain the relationship of this policy to these standards. You need to reference technical hardware, software, and configuration standards for IT assets throughout the seven domains.}

Procedures

{Explain how you intend to implement this policy for the entire organization. This is important because it is where you must explain and define your separation of duties throughout the seven domains of a typical IT infrastructure. All seven domains must be listed in this section as well as who is responsible for ensuring the C-I-A (confidentiality, integrity, and availability) of information is followed.}

Guidelines

{Explain any potential roadblocks or implementation issues that might arise that would need to be overcome. Any disputes or gaps in the definition and separation of duties responsibility may also need to be addressed in this section.}
