In the previous course, you learned about how security professionals employ cryptography, a system of algorithms that hide data. That system can be unlocked with a key provided to those who have a need to know that data. An important part of cryptography is how to manage these keys to the kingdom. This involves learning and understanding enterprise key management systems and concepts.

Cryptography is the application of algorithms to ensure the confidentiality, integrity, and availability of data while it is at rest, in motion, or in use. Cryptography systems can include local encryptions at the file or disk level, or databases, or they can extend to an enterprise-wide public key infrastructure for whole agencies or corporations.

In this project, you will create both an enterprise key management plan and policy for a company. The length of the plan should be eight to 10 pages double-spaced. The length of this policy should be two to three pages double-spaced. There are seven steps to complete the project. Most steps of this project should take no more than two hours to complete, and the project as a whole should take no more than one week to complete. Begin with the workplace scenario, and then continue to Step 1, “Identify Components of Key Management.”

    Step 1: Identify Components of Key Management

    An important part of the new electronic protected health information (or e-PHI) system will be key management. As a security architect, you know that key management is often considered the most difficult part of designing a cryptosystem. The overall information in this step can be fictitious or modeled after an existing corporation, which should then be cited using APA format. The idea is to provide an overview of the current state of enterprise key management for Superior Health Care. To do so, you’ll need to know about authentication and the characteristics of key management. Brush up on your knowledge of authentication by reviewing the authentication resources. Then, provide a high-level, top-layer network view (diagram) of the systems in Superior Health Care. To do this, start by reading these resources on data at rest, data in use, and data in motion. The diagram can be a bubble chart or Visio drawing of a simple network diagram with servers. Independent research may be used to find one to use.Next, identify data at rest, data in use, and data in motion as it could apply to your company. Focus on where data is stored and how it’s accessed is a good place to start. Finally, review these resources on insecure handling, and identify areas where insecure handling may be a concern for your organization. Use this information in your implementation plan.In the next step, you will consider key management capabilities.

    Step 2: Learning Key Management Capabilities

    You have successfully examined what are the major components of an enterprise key management system for Superior Health Care. Now you must begin your research into CrypTool, to better understand enterprise key management by using this product. Enter Workspace and complete the “Enterprise key management” exercise. Do some quick independent research on Public Key Infrastructure as it applies to your organization.Note:You will use the tools in Workspace for this step. If you need help outside the classroom, you can register for the CLAB 699 Cyber Computing Lab Assistance (go to Discussions List for registration information) in which you can access resources to enable you to complete this project successfully. Click here to access the instructions for Navigating the Workspace and the Lab Setup. Click here to access the Project 1 Workspace Exercise Instructions. Explore the tutorials and user guides to learn more about the tools you will use. Then, enter Workspace.In the next step, you will identify the key management gaps, risks, solutions, and challenges found in corporations.

    Step 3: Identify Key Management Gaps, Risks, Solutions, and Challenges

    In the previous step, you identified the key components of an enterprise key management system. In this step, you will conduct independent research on key management issues in existing corporations. These will be used to help identify gaps in key management, in each of the key management areas within Superior Health Care. First, conduct independent research to identify the gaps in key management that are in existing corporations. Any factual information should be cited using APA format. If data is lacking, use fictitious information.Then, identify the posed risks to the cryptographic systems as a result of these gaps, including but not limited to crypto attacks. Read these resources to brush up on your understanding of crypto attacks.Next, propose solutions that the companies could have used to address these gaps. Be sure to identify what is needed to implement these solutions. Finally, identify challenges other companies have faced in implementing a key management system. Include any proposed remedies to these challenges. Include this information in your enterprise key management plan. Also create a summary table of the information into a table to be included in the plan.You will use and submit this information in your implementation plan.In the next step, you will provide additional ideas for the CISO to consider.

    Step 4: Provide Additional Considerations for the CISO

    You have satisfactorily identified key management gaps. Now, since you are compiling information for the CISO, consider these additional objectives of an enterprise key management system.

    1. Explain the uses of encryption and the benefits of securing communications by hash functions and other types of encryption. When discussing encryption, be sure to evaluate and assess whether or not to incorporate file encryption, full disc encryption, and partition encryption. Discuss the benefits to using DES, triple DES, or other encryption technologies. To complete these tasks, review the resources provided to you. You’ll need to understand the following topics:
      1. uses of encryption
      2. hash functions
      3. types of encryption
      4. DES
      5. triple DES
    2. Describe the use and purpose of hashes and digital signatures in providing message authentication and integrity. Check out these resources on authentication to further your understanding. Focus on resources pertaining to message authentication.
    3. Review the resources related to cryptanalysis, then explain the use of cryptography and cryptanalysis in data confidentiality. Cryptanalysts are a very technical and specialized workforce. Your organization already has a workforce of SEs. Conduct research on the need, cost, and benefits to adding cryptanalysts to the corporation’s workforce. This is to support part of the operation and maintenance function of the enterprise key management system. You are determining if it’s more effective to develop the SEs to perform these tasks. If the corporation does not develop this new skilled community, what are other means for obtaining results of cryptanalysis?
    4. Research and explain the concepts, in practice, that are commonly used for data confidentiality: the private and public key protocol for authentication, public key infrastructure (PKI), the x.509 cryptography standard, and PKI security. Take time to read about the following cryptography and identity management concepts: public key infrastructure and the x.509 cryptography standard.

    Use this information in your implementation plan.In the next step, you will provide information on different cryptographic systems for the CISO.

    Step 5: Analyze Cryptographic Systems

    In the previous step, you covered aspects of cryptographic methods. In this step, you will provide the CISO with information on different cryptographic systems either in use by other companies or systems that the company should consider procuring. You will need to independently research what key system products are available. You may research a company you have worked for or know about regarding the use of an enterprise key management system. The idea is for you to get acquainted with different systems that could be used by Superior Health Care.Describe the cryptographic system, its effectiveness and efficiencies. Provide analysis of the trade-offs of different cryptographic systems. Review and include information learned from conducting independent research on the following:

    • security index rating
    • level of complexity
    • availability or utilization of system resources

    Also include information on expenses as pertains to various cryptographic ciphers. Check out this resource on ciphers to familiarize yourself with the topic.Use this information in your implementation plan.In the next step, you will begin final work on the enterprise key management plan.

    Step 6: Develop the Enterprise Key Management Plan

    In the previous steps, you have gathered information about systems in use elsewhere. Using the learning and materials produced in those steps, develop your enterprise key management plan for implementation, operation, and maintenance of the new system. Address these as separate sections in the plan.In this plan, you will identify the key components, the possible solutions, the risks and benefits comparisons of each solution, and proposed mitigations to the risks. These, too, should be considered as a separate section or could be integrated within the implementation, operation and maintenance sections.A possible outline could be:

    • introduction
    • purpose
    • key components
    • implementation
    • operation
    • maintenance
    • benefits and risks
    • summary/conclusion

    The length of this report should be a 8-10 page double spaced Word document with citations in APA format. The page count does not include figures or tables. There is no penalty for using additional pages if you need them. Include a minimum of three (3) references. Include a reference list with the report.Submit your plan to the Assignment folder. When you are finished, turn your attention to the enterprise key management policy, which is the final step.Before you submit your assignment, review the competencies below, which your instructor will use to evaluate your work. A good practice would be to use each competency as a self-check to confirm you have incorporated all of them in your work.

    • 1.1: Organize document or presentation in a manner that promotes understanding and meets the requirements of the assignment.
    • 1.2: Develop coherent paragraphs or points to be internally unified and function as part of the whole document or presentation.
    • 1.3: Provide sufficient, correctly cited support that substantiates the writer’s ideas.
    • 1.4: Tailor communications to the audience.
    • 2.1: Identify and clearly explain the issue, question, problem under consideration.

    • 7.4: Knowledge of policies, processes, & technologies used to create a balanced approach to identifying and assessing risks to information assets, personnel, facilities, & equipment, and to manage affordable mitigation strategies that meet security needs.

      Step 7: Develop the Enterprise Key Management Policy

      The final step in your assignment requires you to use the information provided in the previous steps to develop the enterprise key management policy that provides the processes, procedures, rules of behavior, and training within the enterprise key management system. Be sure to address different case scenarios and hypothetical situations. You may want to research different policies used by companies and adapt those frameworks for creating your policy. Review and address the following within the policy:

    • digital certificates
      • certificate authority
      • certificate revocation lists

    For example, when employees leave the company, their digital certificates must be revoked within 24 hours. Another is that employees must receive initial and annual security training. Include up to three corporate scenarios and devise policy standards, guidance, and procedures that would be invoked by the enterprise key management policy. Each should be short statements to define what someone would have to do to comply with the policy. The overall information in the corporate scenarios can be fictitious or modeled after an existing corporation, which should then be cited using APA format. The length of this policy should be a two to three-page double-spaced Word document with citations in APA format. Submit your policy to the assignment folder.
    Before you submit your assignment, review the competencies below, which your instructor will use to evaluate your work. A good practice would be to use each competency as a self-check to confirm you have incorporated all of them in your work.
