Assignment will require you to write 6 to 8 pages (not including cover page) on assessing a threat of your choice.
It is your job to take into account possible threats, assess the likelihood of those threats, and examine the ways in which SIGINT could be used to discover and mitigate those threats. Use as many of the subcategories of SIGINT as you can to help you determine how large the threat is and how you would counter this threat.
Use your imagination. Be as creative as you want to be regarding the threat you have chosen. Ensure that you quantify your argument with solid data.
