Cryptography HomeworkThe main part of this homework assignment is focused around reinforcing the cryptography topics covered in class this week.After you've complete the main assignment, please make sure that you have created a personal Azure account. We have provided a document with step-by-step deliverables. You will also be asked to submit a screenshot of your Azure account as part of this homework.Lastly, we've included a reminder about Career Services and completing milestones. Make sure to complete your milestone to become employer competitive.Cryptography Homework: Ransomware RiddlesBackgroundIn this homework assignment, you will play the role of a cybersecurity analyst at Nakatomi Hospital.Unfortunately, one of the hospital's doctors opened up an email containing ransomware.This ransomware spread throughout the hospital and encrypted all of the Patient Records.The ransomware has given you two options to decrypt and retrieve the patient records: Either pay 100 bitcoins or solve six riddles.Since you refuse to pay off any ransom, you'll have to solve six cryptographic riddles. Act fast: the doctors need to access the patient records as lives are at stake!Additionally, a Career Service Milestone is located at the end of this file. Complete it to learn how to become more Employer Ready.Topics Covered in Your AssignmentsEncryptionDecryptionCaesar CipherEncoding and DecodingBinarySymmetric and Asymmetric EncryptionOpen SSLKey/IVPublic/Private KeysKey DistributionHashingHashing AlgorithmsHashcatSteganographySteghideFiles RequiredThe entire homework assignment can be completed on a publicly available website linked below. If for any reason, the website has issues or is unavailable, an offline copy has also been provided.Website: https://sites.google.com/view/cryptobreakout/Offline Copy: Crypto_HomeworkIf you complete the offline version, you will simply need to submit your answers to the instructor.Instructions:In order to solve each riddle, you will need to apply cryptographic concepts covered in the past three lessons. concepts will need to be applied.Once the riddle has been solved, submit your answer on the bottom of each Riddle Page.If you are correct, you will receive a key. Save this key in your notes.Once you have collected all six keys, select the Ransomware Decrypted header on the website and enter all your keys.If all the six keys are correct, the ransomware will be removed and the data will be decrypted.You will need to submit a screenshot as proof that the ransomware has been decrypted.Good luck and act fast as the Nakatomi Patients are counting on you!Azure Account Set-UpDuring the Cloud Security unit and your Project units, you will be using your own personal Azure account. You will not be using the Azure account that you have been using so far been in this class.Please follow the instructions in this Individual Azure Accounts Set-Up GuideYou will need to submit a screenshot of your individual account page at portal.azure.com as proof that you've completed this portion of the homework.

CompetencyIn this project, you will demonstrate your mastery of the following competencies:Analyze the design of a risk mitigation plan for its inclusion of best practices in the fieldIdentify legal and ethical considerations in risk analysis and mitigation within an information technology environmentScenarioYou are a risk management consultant and have been contacted by the chief information officer (CIO) of Workers Werks Credit Union (WWCU), a mid-size but growing credit union, to conduct an evaluation of its current IT cybersecurity risk management plan. Data privacy is a big concern in the banking sectors, and the CIO is concerned that WWCU’s current plan is outdated and has significant weaknesses.In your conversation with the CIO, you gather the following information about the situation:Current plan: The credit union adopted the current cybersecurity risk plan three years ago, but the CIO is concerned about possible gaps in the plan and would like to update it.Workforce: The credit union has experienced significant revenue growth, and the number of employees with access to its IT infrastructure has grown exponentially in the last five years.WWCU now has nearly 1,000 users with different levels of access to its central database.Strategy: The credit union is looking to expand into new markets in the coming year and will need to make significant changes to its IT infrastructure.Compliance: The CIO is concerned not only about legal compliance but also ethical issues related to the protection of personally identifiable information (PII) of its customers. The company has set these priorities related to legal and ethical compliance:Address the current legal environment (domestic and international)Anticipate emerging issuesMeet industry ethical standards (e.g., SANS IT code of ethics)Match best practices for risk planning within the industryDirectionsRisk Analysis ReportThe CIO is asking you to prepare a 3–4 page report that evaluates the company’s current IT Security Risk Management Plan, linked in the Supporting Materials section.The report should contain the following:Scope: Evaluate the scope and comprehensiveness of the current plan.How does the plan describe its objectives?How does the plan balance risk and cost?In what ways does the plan cover the business objectives end to end?How does the plan address all stakeholders who could be impacted by a cybersecurity attack?Risk: Determine how the current plan identifies risks.How does the plan identify the risks, vulnerabilities, and threats that could impact mission-critical business functions and processes?How does the plan identify industry-related risks (internal and external)?Impact: Analyze how the identified risks might impact the organization’s assets.How does the plan identify key assets and activities that need to be protected?How does the plan estimate the financial impact of losses?How does the plan address business continuity and asset replacement?Mitigation: Evaluate the current plan’s mitigation recommendations.How effectively does the plan translate the risk assessment into a risk mitigation plan?How does the plan prioritize risk elements?Legal Compliance: Assess how the plan addresses legal considerations.Non-Compliance: Determine how the plan anticipates the implications of non-compliance.Ethical Considerations: Assess how the plan aligns with current ethical codes within the cybersecurity field.

The Courses and Classes Records System contains the Maintain Class records use case description and the class diagram of a new software product that keeps track of the records of both courses and their offerings as classes for educational institutions. The goal of this software product is to maintain and track information about the courses offered by the institution and the classes with which these courses are offered. The product supports two kinds of classes—online classes accessible over the internet and face-to-face classes offered on the grounds of the educational institution. The users of the system are the staff of the institution. You are hired as a consultant software architect to generate the sequence diagram for the Maintain Class records use case by utilizing the information in the use case description and the class diagram.
