You have been promoted as the manager of the e-commerce site for the company you working for. You are concerned about a recent SQL attack that happened. Your team reacted to the situation by notifying you immediately. You and your team were successful in containing and correcting the issues that allowed the website and database to be compromised by an SQL injection attack.
Knowing that many of the issues can be created by human error, you have decided to evaluate the processes your team uses when they code. As their leader, it is your responsibility to be current on all the best secure coding practices. Your job is to create guidelines for best coding practices, which you will present to your team.
Follow the instructions below
Provide at least three reasons why it is less expensive to build secure software than to correct security issues after a breach.
Outline the objectives and purpose of your company’s “best secure coding practices” and explain how it will influence your division.
Evaluate which method of the secure software development lifecycle will best serve your team, and explain how you plan on implementing your thoughts into your existing processes.
Identify three resources that can be used as “reference material” and act as a beginner’s guide for new employees. Outline the importance of each resource and how each resource can assist new coders. 
Outline all the major aspects of the best practice coding guideline, including objectives, purpose, resources, and methodology

Question #1: Research two software firewalls and explain the advantages and disadvantages of each one of them. Which one would you recommend and why?
Question #2: What are the challenges in securing networks (internet, LANs, wireless)? Which network is most difficult to secure and why?

Using  the same dataset as last week or a different one, select two  qualitative variables and two quantitative variables. Explain why you  selected these variables. 
Analysis: For your qualitative variables, create a contingency table and calculate the association between them. 
For  your quantitative variables, calculate the correlation between them.  Include scatter plot to visually represent this relationship. 
Interpretation:  Explain your findings. What does the association or correlation say  about the relationship between your variables? Is the relationship  strong, weak, positive, negative, or nonexistent? 
Reflection:  Reflect on the importance of understanding associations and  correlations in data analysis and how they can guide further data  investigation. 
Submission Format: Your submission should be a maximum of 500-600 words. Submit your assignment in APA format as a Word document or a PDF file. Include  both your written analysis and any visualizations or tables that  support your findings. If you use any software for your calculations  (Excel), please include your code or  formulas as well.

Purpose
In this assignment, you will examine a forensic disk image for evidence of corporate espionage. Read the scenario document carefully, as you may consider it interview notes with your client. This represents a more complex scenario than Investigation 01 and thus contains a greater degree of irrelevant data. Be sure to give yourself plenty of time to perform the examination, and be sure to take advantage of Autopsy’s features to assist your disambiguation.
Instructions
You’ll need to use the following resources to complete the assignment:
Investigation 02 Sample Evidence*
Autopsy the open-source forensic suite* (or another suite, such as EnCase or FTK.)
(Optional) Download and use the report template (See the Investigation and Forensics Challenge module for the templates)
*Accessed via the Virtual Lab.
After reading the Investigation 02 Scenario, open your forensic tool and import the sample evidence into the tool. Begin a forensic report and begin your search. As you do, be sure to take special note of these answers to these questions. These questions represent those that need to be answered to arrive at a logical conclusion to this scenario. They are provided here, but in the future, you will be required to decide these questions on your own.
Scenario
This scenario takes place circa 2008.
M57.biz is a hip web start-up developing a body art catalog. They’ve pulled in over $3 million in funding with a net return of $10 million. The company is small, with only seven employees, including founder Alison Smith. Alison was co-founder with her long-time partner Raoul Perdoga, but she recently forced him out of the business following a nasty break-up.
Current employees are:
President: Alison Smith
CFO: Jean Jones
Programmers: Bob Blackman, Carol Canfred, David Daubert, Emmy Arlington
Marketing: Gina Tangers, Harris Jenkins
BizDev: Indy Counterching
Despite their recent success, they have a decentralized office. Most people work at home or on the road. Communication and collaboration are primarily by email through their own @m57.biz domain. This worked fine until a spreadsheet containing confidential proprietary company information was posted as an attachment in the technical support forum of a competitor’s website.
The spreadsheet came from CFO Jean’s computer, but she denies any knowledge of the leak. She says that Alison asked her to prepare the spreadsheet as part of a new funding effort and to email it to her. Alison denies she ever asked for the spreadsheet and never received a copy by email. A recreation of the spreadsheet table is found below for you to use.
Questions
When did Jean create the spreadsheet? Jean asserts that she created the spreadsheet after Alison had asked for it by email.
How did the spreadsheet get from Jean’s computer to the competitor’s website? Jean says she emailed it to Alison but denies ever visiting the competitor’s website.
Is anyone else from the company involved? What about people who are not in the company? What possible motive could they have?
If what Jean says is true, what steps can we take to continue our investigation?

Week 2 Assignnment: Key Hardware 
This week’s assignment we are going to start digging into the specifics of the hardware that makes up both of our water treatment facilities, remember your company is responsible for purification of both drinking water and wastewater. You need to make sure you note key hardware and machines for the actual processes, but you also need to do work on the devices and systems you will need for the control systems for both facilities. The goal of the paper is to develop a rough list of hardware that goes into the water treatment facilities. If you remember your video and documents from last week, things will be much easier in knowing what type of hardware is needed.
Assignment Guidelines
Step 1: Using the documents from last week and Google, you will need to list all the key hardware and machines that make up the water treatment facilities and their ICS/SCADA systems. Below you will find a few sources of information to help you get started. Also, a hint, lots of companies in water treatment have technology pages. Don’t forget to mention what hardware and security you would use to build out the network, you only need to focus on standard networking for this week.

 https://www.process-logic.com/content/images/SCADA.pdf
Step 2: Once you have gathered up all the information you will compile the data into a PowerPoint presentation. Each step of the processes will be a single slide. Each slide will list the hardware needed for that respective step, make sure to include photos and brief descriptions of the hardware explaining their usage and their role in the process. Your final slide should cover the hardware and security you would put into place for the networking.
