Operating Systems Vulnerabilities Congratulations. You are the newly appointed lead cybersecurity engineer with your company in the oil and natural gas sector. This is a senior-level position. You were hired two months ago based on your successful cybersecurity experience with a previous employer. Your technical knowledge of cybersecurity is solid. However, you have a lot to learn about this company's culture, processes, and IT funding decisions, which are made by higher management. You have recently come across numerous anomalies and incidents leading to security breaches. The incidents took place separately, and it has not been determined if they were caused by a single source or multiple related sources. First, a month ago, a set of three corporate database servers crashed suddenly. Then, a week ago, anomalies were found in the configuration of certain server and router systems of your company. You immediately recognized that something with your IT resources was not right. You suspect that someone, or some group, has been regularly accessing your user account and conducting unauthorized configuration changes. You meet with your leadership to discuss the vulnerabilities. They would like you to provide a security assessment report, or SAR, on the state of the operating systems within the organization.  You're also tasked with creating a non­technical narrated presentation summarizing your thoughts. The organization uses multiple operating systems that are Microsoft-­based and Linux­-based. You will have to understand these technologies for vulnerability scanning using the tools that work best for the systems in the corporate network. You know that identity management will increase the security of the overall information systems infrastructure for the company. You also know that with a good identity management system, the security and productivity benefits will outweigh costs incurred. This is the argument you must make to the stakeholders.

A Usability Evaluation examines the way users interact with products and services in order to achieve a goal. Often times, there are measures that are tied to those goals that are quantified. Academic literature has a robust catalog of research on studies that examine various perspectives that explore user attitudes and experiences. Such attitudes and experiences include: Learnability Findability Satisfaction Efficiency Memorability Effectiveness Ease of Use Error Handling Remember, usability is not one-dimensional. It is a complex system of properties. That integrates many factors. It is subjective from user to user. For this assignment, you are asked to explore one of these topics. You are to conduct an analytical research review of the assigned usability category/dimension above. You should evaluate a single variable in the context of the usability evaluation study cycle. Your paper will include the following: Abstract Title Page Introduction What is a Usability Study How does a usability study include the term you've selected (e.g. satisfaction) Literature Review of Term (e.g. detailed review of satisfaction and the various measures) Future Research Topics To Consider Conclusion Considerations: Must provide a minimum of seven scholarly sources that analyze the term and its meaning

Option #1: Johnson Video StoreYou are a database consultant with Ace Software, Inc., and have been assigned to develop a database for the Johnson Video Store in town. The owners have been keeping their records of videos and DVDs purchased from distributors and rented to customers in stacks of invoices and piles of rental forms for years. They have finally decided to automate their record keeping with a relational database.You sit down with the owners to discuss their business and watch their operation for about a week. You discover quickly that a video and a DVD are both copies of a movie kept in a separate plastic case that is rented out. They have several copies of each movie they rent; therefore, there are several videos and DVDs for each movie title. You learn that in their inventory they have several thousand videos and DVDs, which they get wholesale from about a half dozen distributors. The video and DVD prices for them are based on the quantity of their shipment and the past business they have done with each company.The price of a DVD for a movie might be different from the price of a video for the same movie, even from the same distributor. Each distributor provides different types of movies (e.g., suspense, horror, mystery, comedy, etc.). A single distributor may provide several different types of movies in both video and DVD format. It is possible to obtain the same movie from multiple distributors and at different wholesale prices.Each video and DVD has a unique identification number that The owners assign in their inventory, in addition to the distributor's serial number for the item. Each movie also has a unique identification number. The owners assign in addition to the title and any movie IDs the distributors use in their electronic catalogs. Distributors provide electronic catalogs to the owners, and the information from these catalogs must be included in the database.The owners need to record when a video or DVD is rented, when a video or DVD is returned, and all customer charges such as late and damaged fees, failure to rewind fees, and taxes. They need a report of which videos are returned late because there are standard and late charges. On occasion, there are discount prices for specific movies or types of movies. Customers want to rent movies based on actors or actresses, running length, type of movie, rating, year released, the director, and the Academy Awards won (by the movie, the actors, the actresses and/or the directors). Customers also want to know how many videos they have rented in the last month, year, and so forth. The owners need to keep only basic information on customers in their database, such as name, address, telephone numbers, etc.There must be no limit to the number of video and/or DVD copies of a movie that the owners can have in their inventory. Video/DVD ID numbers, movie ID numbers, and distributor ID numbers for videos, DVDs, and movies are all different. Also, each movie must be able to have an unlimited number of actors, actresses, directors, and Academy Awards (i.e., Oscars). Other types of awards (e.g., Golden Globe, People's Choice, etc.) are not of interest for this application. The rental of equipment, sale of videos, DVDs, popcorn, etc., is not to be kept in the database.Draw an ERD utilizing a software of your choice.Develop metadata from the ERD and document in an Excel spreadsheet.Using PostgreSQL, develop and execute an SQL script file of DDL SQL to create the database tables in the metadata document.Using PostgreSQL, develop and execute an SQL script file of DML SQL INSERT statements to populate the tables using SQL INSERT statements for at least 5 rows of data per table.Using PostgreSQL develop and execute an SQL script file to:Show the contents of all tablesRetrieve all of the customers' names, account numbers, and addresses (street and zip code only), sorted by account numberRetrieve all of the DVDs rented in the last 30 days and sort in chronological rental date orderUpdate a customer name to change their maiden names to married names. You can choose which row to update. Make sure that you use the primary key column in your WHERE clause to affect only a specific row.Delete a specific customer from the database. You can choose which row to delete. Make sure that you use the primary key column in your WHERE clause to affect only a specific row.The metadata should be submitted in an Excel spreadsheet. All other outputs for the database design, SQL code, and SQL results should be submitted in a single Word file in order, by step, and clearly labeled. The Word file should also have a preface describing the database lifecycle steps and methodologies and a conclusion section containing lessons learned from this project.Your paper should be 6-10 pages in length, not including the cover page and references page, and conform to CSU-Global Guide to Writing and APA (Links to an external site.). Include at least five credible references in addition to the course textbook. The CSU-Global Library is a good place to find these references.
