Turn in a narrative incident report, written and professionally designed (you may use Canva and similar design tools) for external audiences (victims, media, etc). 
I suggest using New York State’s report on the 2020 Twitter hackLinks to an external site. or the Australian National University report on a 2018 data breachLinks to an external site.  as guides to content, structure, and length/word-count, though you are not required to adhere strictly to them. (New York State does get a bit wordy…)
Use this link for an example as well as the file below https://www.dfs.ny.gov/Twitter_Report
I am going to give you some research I did during the year the incident I chose was the 23 and me data breach. For the number of sources it did not specifiy and I allready collected some in the week 1-3 pdf.  There is also a presentation that has some useful information on the breach as well.
