Any topic (writer’s choice)

For this assignment, you will create several spreadsheets in an Excel workbook and demonstrate different functions. Read all the instructions in this module item and view the required tutorials before you begin. If you are familiar with functions used in Excel, you will still want to review these to see what is expected.

Write 5 different digital crime scenarios

Each crime should have different digital data sources such as Laptop, smartphone, network logs, social media sites, and so on.
These cases also illustrate the current issue in Digital investigation [Big Heterogeneity volume of data].
Develop a table of five different crimes and list every digital source in the second column.

The next stage will generate a data set for these cases to perform digital investigation experiments.

For example, please have a look to the link below:

Planning and Audits, Unit III Homework

Instructions
The purpose of this homework assignment is to allow you to research information about the healthcare industry that addresses the requirements a healthcare organization must comply with. You will relate the Health Insurance Portability and Accountability Act (HIPAA) Privacy and Security rules to NIST standards and encryption technologies to ensure confidentiality of electronic protected health information (ePHI) transmission.
You will evaluate HIPAA requirements, identify what ePHI data consists of, and apply HIPAA Privacy and Security rules to ensure confidentiality, integrity, and availability. Finally, you will relate the security requirements for protected heath information (PHI) to an overall privacy and security strategy for a healthcare organization.
You will use a text document to develop your homework assignment by completing the sections listed below:

Now that you have come up with a plan to gain access to Haverbrook's target systems, it's time to start planning how you will maintain that access once you get it.

You know that attempt will be useless unless you can not only extract the information you were looking for but stay unnoticed, and you also need to able to get back inside as needed.

A big part of managing a network is to secure it; therefore, you should take nothing for granted. You have to have a well-defined plan to get back into the target environment at will; second chances are much harder since they will be expecting you at that point.

As a penetration tester, you need to figure out how you will maintain control of the system. To have a clear execution plan, you need to think about the best techniques and procedures when pivoting to obtain main access and control of the targeted system.
