Summary:Produce an ER Model for the following scenario (presented in Step 1 below) and business need, for the Pythagoras Math Academy.  Reference the attached video (Course Project Ph2 Video.mp4), for a full introduction and demonstration and expectations for this project.Deliverables:

• ER Model for the scenario presented. 
• You have the option to use MS Visio (if you have the software) to produce your ER Model.  
• Alternatively, if you do not have MS Visio, you can use the ERD PLUS (Open source ER Modeling Software) and produce your ER Model. 

***The submission is a Word document with the ER Model diagram copied.  Do not send any type of image.  The submission must be the image copied into a Word document.  Please include a cover sheet with your full name, the class and  the university spelled correctly.  Please include any details necessary to describe the results. 
Required Software:

• MS Visio by Microsoft OR
• ERD PLUS, Open Source Offering. This offering is cloud-based, and you do not need to download any clients. You will need to create an account (username and password), link to this offering follows: https://erdplus.com 

Lab Steps:Step 1: Read and understand the Scenario and Business needs presented below. Define and document the ENTITIES, and RELATIONSHIPS, required to address the business needs. The nouns in the scenario below will give the ENTITIES that you will need. Finally, the verbs will describe the RELATIONSHIPS.Scenario and Business Need The Pythagoras Math Academy is in need to develop a database to keep track and control of his students, teachers, and classes offered. Teachers are able to teach multiple courses. But they are required to be certified on the course they are teaching. For example, only a group of teachers are certified to teach Algebra, and other Geometry. Students can take multiple courses. Courses are taught by teachers with the proper certification and have multiple certs as needed.  Courses are taught in one of the classrooms at one of the School’s several sites.Each classroom is optimized to serve the needs for a course (for example some courses might require computer labs and whiteboards). The school needs to keep track of the math courses delivered in each of the sites.Step 2: For this project, you are required to use MS Visio or ERD PLUS to produce the deliverables.If you are using MS Visio follow the steps below:

• Reference the Course Project Ph2 VIDEO.mp4, for a short demonstration and tutorial of this tool, and project overview/ expectations.
• Open MS Visio
• Click on the Software Database Template in the main window
• Select the Database Model Diagram Template to open a new file.
• Save the File and ensure to have in your file name PROJECT2_LastName_FistInitial.

If you are using ERD PLUS.

• Watch the recorded short tutorial for this tool. Reference the attached video as follows: Course Project Ph2 VIDEO.mp4.
• From the ERP PLUS main interface, select DOCUMENTS –> NEW DIAGRAM (NAME YOUR DIAGRAM) –>ER DIAGRAM –> CREATE
• Reference demonstration video for how to navigate tool, how to create entities, add attributes, relationships, and Cordiality. Demonstration video attached as follows: Course Project Ph2 VIDEO.mp4

Step 3: Define and Database ENTITIES

• Add an entity for each Table you identified in the Scenario and Business Need.
• You will use the MS Visio tool, or the ERD PLUS open source offering to complete this step.

Step 4: ADD the required ENTITY ATTRIBUTES  

• Add the required Attributes for each Entity that you feel would help to define each Entity as needed.
• Select one of the attributes to be PRIMARY KEY (PK)

Step 5: Define RELATIONSHIPS

• Use the Crow’s Feet Notation.
• Reference recorded demonstrations on how to use these notations, for MS Visio and ERD PLUS. Reference attached video as follows: Course Project Ph2 VIDEO.mp4
• Drag and drop (draw) relationships between the entities you defined.
• Connect the ends to the two entities for each relation.
• Defined the Primary Key for the parent entity.

Step 6: Define CARDINALITY RELATIONSHIPSet the cardinality for each of your relationships defined in Step 5.  For MS Visio: select a relationship line in the drawing area that is connecting two entities. In the Database Properties window, select the miscellaneous category. Select the cardinality for the selected relationship.Step 7: Upload your Work 

• Save the File and ensure to have in your file name PROJECT2_LastName_FistInitial. 

***The submission is a Word document with the ER Model diagram copied.  Do not send any type of image.  The submission must be the image copied into a Word document.  Please include a cover sheet with your full name, the class and  the university spelled correctly.  Please include any details necessary to describe the results. Rubric:

• 10 points: ER Model (MS Visio OR ERD PLUS)
• 10 points: Entities: Minimum of Three entities are represented
• 10 points: Attributes: Minimum of Two attributes for each Entity. Most would require more than two attributes, and I am only requiring two per entity.
• 10 points: Relationships: Minimum Three relationships are presented.
• 10 points: Cardinality is defined and specific for each relationship with Crow’s foot notation.

By reading below case study describe the risk that was exploited. Also, tell how you think that exploit could be avoided using proper technology and security policies

Private Sector Case Study:

A franchisee of a national hamburger chain in the southern United States was notified by Visa U.S.A, Inc. and the U.S. Secret Service of the theft of credit card information in August 2008. The franchisee has a chain of eight stores with annual revenue of $2 million. The chain focused on the technology of its point-of-sale (POS) system. A leading vendor that allowed for centralized financial and operating reporting provided the POS system. It used a secure high-speed Internet connection for credit card processing. The company determined that neither the POS nor credit card authorization connection was the source of the breach. Although the POS was infected, the source of the breach was the network. Each of the franchisee’s stores provided an Internet hotspot to its customers. It was determined that this Wi-Fi hotspot was the source of the breach. Although considerable care was given to the POS and credit card authorization process, the Wi-Fi hotspot allowed access to these systems. It was determined the probable cause of the breach was malware installed on the POS system through the Wi-Fi hotspot. The malware collected the 232credit card information, which was later retrieved by the thief. This was a PCI DSS framework violation. The PCI DSS framework consists of over 200 requirements that outline the proper handling of credit card information. It was clear that insufficient attention was given to the network to ensure it met PCI DSS requirements. For discussion purposes, the focus is on the network. The PCI DSS outlines other standards that may have been violated related to the hardening of the POS server itself. The following four PCI DSS network requirements appear to have been violated: • Network segregation • Penetration testing • Monitoring • Virus scanning PCI requires network segments that handle credit cards be segmented. It was unclear whether there was a complete absence of segmentation or if weak segmentation had been breached. PCI DSS outlines the standards to ensure segmentation is effective. If the networks had been segmented, this breach would not have occurred. PCI requires that all public-facing networks be penetration tested. This type of testing would have provided a second opportunity to prevent the breach. This test would have uncovered such weaknesses within a Wi-Fi hotspot that allowed the public to access back-end networks. PCI also requires a certain level of monitoring. Given the size of the organization, monitoring might have been in the form of alerts or logs reviewed at the end of the day. Monitoring could include both network and host-based intrusion detection. Monitoring may have detected the network breach. Monitoring may also have detected the malware on the POS system. Both types of monitoring would have provided opportunities to prevent the breach. PCI requires virus protection. It was unclear if this type of scanning was on the POS system. If it was not, that would have been a PCI DSS violation. Such scanning provides one more opportunity to detect the malware. Early detection would have prevented the breach. The PCI DSS requirements are specific and adopt many of the best practices from other frameworks such as ISO. The approach is to prevent a breach from occurring. Early detection of a breach can prevents or minimize card losses. For example, early detection of the malware in this case study would have prevented card information from being stolen. Some malware takes time to collect the card information, which must then be retrieved. Quick reaction to a breach is an opportunity to remove the malware before any data can be retrieved.
