Cyber espionage has become common in the last decade. Can you name at least two cyber espionage incidents that occurred in 2019-2020? Do you believe the United States plays a key role in cyber espionage?

The Best Free Software: http://www.pcmag.com/article2/0,2817,2381590,00.asp Instructions: Describe five separate software and submit the following information: Submission Instructions: Software Name: Category (System, Utility, or Application) Purpose: Describe what features the software provides, and why you would use or currently use the software. (Not all users take advantages of all software features.) Opinion: Your opinion of the software. You may use any word format to document your assignment, i.e., text or tables. Please note: An application software improves users’ productivity and supports the tasks. Utility software (also known as service program, service routine, tool, or utility routine) is a type of computer software; it is specifically designed to help manage and tune the computer hardware. The operating system, also known as system software, manages the computer—I like to call it the “BOSS” of the computer system. I hope this explanation offers further level of distinctions among software programs.

Instructions: It is essential for organizations to have plans and procedures in place in order to both prevent crises and recover from them. Crisis preparedness involves protecting against fires, using computer forensics, and creating and maintaining a disaster recovery plan.  What is a disaster recovery plan? What role do computer forensics play in a disaster recovery plan? Using the Internet, locate a disaster recovery plan for an organization of your choice. What issues does this plan address? Is anything missing?  In a 1- to 1½-page Word document, write a paper in the following format: Paragraph 1: Introduction to the purpose of this paper. Paragraph 2: Describe the components of a disaster recovery plan. Paragraph 3: What role do computer forensics play in a disaster recovery plan? Paragraph 4: Summarize the disaster recovery plan you found. What issue does this plan address? Is anything missing? Paragraph 5: Conclusion

For decades, relational databases remained essentially unchanged; data was segmented into specific chunks for columns, slots, and repositories, also called structured data. However, in this Internet of Things (IoT) era, databases need to be reengineered because the very nature of data has changed. Today’s databases need to be developed with the needs of IoT in mind and have the ability to perform real-time processing to manage workloads that are dynamic. For example, relational databases should be able to work with real-time data streaming and big data (an example was presented in the Unit III Lesson). Scenario: Falcon Security wants their customers to be able to view security video footage in real-time and provide customers with the ability to query video footage for viewing. Choosing a database solution such as MongoDB would allow Falcon Security to store customer video footage in the same database as the metadata. To do this, Falcon Security needs a way to manage the demands of real-time data streaming for real-time analytics. Conduct some research for a NoSQL database application, such as MongoDB or Cassandra, that could meet this need. How would switching to a real-time database solution help Falcon Security remain competitive? Create a PowerPoint presentation that includes the components listed below. Provide a brief introduction to IoT. Present the argument to the Falcon Security CEO that switching to a more dynamic database structure (NoSQL real-time database) will meet the demands of IoT. Introduce some features of the database you chose, whether it is MongoDB, Cassandra, or another database. Describe how switching to a more dynamic database will give Falcon Security a competitive advantage. Your presentation must be a minimum of six slides in length (not counting the title and reference slides), and you must use at least two academic resources. Any information from a resource used must be cited and referenced in APA format.

Develop a Python application that incorporates using appropriate data types and provides program output in a logical manner. Your program should prompt a user to enter a car brand, model, year, starting odometer reading, an ending odometer reading, and the estimated miles per gallon consumed by the vehicle. Store your data in a dictionary and print out the contents of the dictionary. Python has built-in string validation methods for basic data. It can check if a string is composed of alphabetical characters, alphanumeric characters, digits, etc. str.isalnum() This method checks if all the characters of a string are alphanumeric (a-z, A-Z and 0-9). print(‘ab123’.isalnum()) True print(‘ab123#’.isalnum()) False str.isalpha() This method checks if all the characters of a string are alphabetical (a-z and A-Z). print(‘abcD’.isalpha()) True print(‘abcd1’.isalpha()) False str.isdigit() This method checks if all the characters of a string are digits (0-9). print(‘1234’.isdigit()) True print(‘123edsd’.isdigit()) False str.islower() ( This method checks if all the characters of a string are lowercase characters (a-z). print(‘abcd123#’.islower()) True print(‘Abcd123#’.islower()) False str.isupper() This method checks if all the characters of a string are uppercase characters (A-Z). print(‘ABCD123#’.isupper()) True print(‘Abcd123#’.isupper()) False Assignment Instructions Write a Python program that performs the following tasks: Read from the console an arbitrary string S of length less than 50 characters. In the first output line, print True if S has any alphanumeric characters. Otherwise, print False. In the second line, print True if S has any alphabetical characters. Otherwise, print False. In the third line, print True if S has any digits. Otherwise, print False. In the fourth line, print True if S has any lowercase characters. Otherwise, print False. In the fifth line, print True if S has any uppercase characters. Otherwise, print False. Develop Python code that implements the program requirements.

Overview The key to being a good forensic investigator and security expert is understanding the field. This includes not only understanding current security topics, but understanding also understanding tools and concepts used in past. Understanding both prepares for the future. The purpose of the research paper is to allow students the opportunity to hone their research and reporting skills by studying a security topic. Assignment Students will pick a research topic to study and report on. The topic must be related to the field of cyber security and have specific application to the study and application of digital forensics. The topic must be approved by both instructors. Research is not intended to create new developments in the field, but to allows students to create a deeper knowledge and insight into digital forensics and cyber security. The paper should consist of solid research, citing at least six sources. Wikipedia sources are allowed, but must be backed by verified experts. The paper should be written in the IEEE standard. (Template included) Research should show that students have a solid understanding of their selected topic as it relates to digital forensics. This should include a section on background research and a section on how the topic has been used in the field, or potential future work. In writing the paper, the final document should contain a title page consisting of your name, topic, class name, and date of submission. Additionally, each paper should include an abstract, introduction, body paragraphs, conclusion, and references. The paper should be approximately five to seven pages in length, excluding the title page. Comments made my teacher after first attempt: There were numerous grammar mistakes that showed me this was not proof read before you turned it in. The formatting was also not in IEEE standard, and you went overboard on the use on images. You also went past the 7 page maximum length requirement. After the first page I stopped pointing out every single error because it would have taken too long. The technical content of your report was also severely lacking. You primarily talked about the different things you can find on different cloud services, but didn’t focus on why these things are important enough.

Defend your argument according to an ethics of purpose, an ethics of principle, and an ethics of consequence (or just consequentialism). In your essay, be sure to do the following: Make clear that you have done the relevant assigned readings by critically reflecting on them and using 5 citations (at least 3 from 3 different assigned articles).  Remember that this is NOT a descriptive research paper.   A start- up company called Medick has been developing a new product for hand held computers that will revolutionize the way nurses keep track of their hospitalized patients. The device will save nurses a great deal of time doing routine paperwork, reduce their stress levels, and enable them to spend more time with their patients.  Medick’s sales force has led the hospital administrators to believe the product will be available next week as originally scheduled. Unfortunately, the package still contains a few bugs.  All of the bugs appear to be minor, but some of the planned tests have not yet been performed.  Because of the fierce competition in the medical software industry, it is critical that this company be the first to market. It appears a well-established company will release a similar product in a few weeks.  If that product appears first, Medick will probably go out of business.  Represent one of these groups: software engineers programming the device; the sales force promoting the device; or the managers of Medick.  Plan a course of action and defend your position using ethical theories, articles and the ACM Code of Ethics.  (Quinn,Ethics for the Information Age)
