University of Maryland CMSC Security and Cipher Tools Python Project
In this exercise you will update your web site to include a password update form and provide additional validation on the password check. Specifically you should create:a. Password update Form – This Python form allows a previously registered user to reset their password after they have successfully logged in.b. Authentication functions – These Python functions will check the following NIST SP 800-63B criteria are met upon password update:• Use the previous criteria for password length and complexity. (This work should already be done.)• Compare the prospective secrets against a list that contains values known to be commonly-used, expected, or compromised (Provided as CommonPasswords.txt).• If the chosen secret is found in the list, the application SHALL advise the subscriber that they need to select a different secret.c. Logger – Create a log to log all failed login attempts. The Log should include date, time and IP address.

CU The Entity Relationship ER Model a High Level Data Framework Question
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.
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 RELATIONSHIP
Set 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.
