Your goal is to find out what knowledge is already out there related to solving or better understanding this problem. These numbers are a minimum. If you can’t/don’t get the whole picture with these eight resources, find more.

Compose an initial post in which you address the following:

•A short recap of the problem you identified

•For each reference,

• • The full APA-formatted citation
  • A summary of the major points or key takeaways related to solving or understanding the problem

Do not use Wikipedia or similar sites. Do not use blog posts unless they are official publications of the relevant companies or their employees (e.g., Mark Zuckerberg’s blog would be an appropriate source for information about Facebook).

Comment on the responses of at least two classmates. Address the following:

• Given the problem, are the references presented appropriate and thorough enough to give a complete picture of the state of the art in addressing it? Why or why not?

1)Chapter 7 discusses situational awareness. Much of the security efforts of the past have been centered around prevention and protection. The increasing sophistication of cyber attacks have shown that no controls are 100% effective, and some compromises do occur. There is a rising realization that in addition to considering prevention and protection, controls that address detection and response are necessary to improve security posture. Please describe how situational awareness is a driver for detection and response controls.

To complete this assignment, you must do the following:

A) Create a new thread. As indicated above, describe how situational awareness is a driver for detection and response controls.

B) Select AT LEAST 3 other students’ threads and post substantive comments on those threads. Your comments should extend the conversation started with the thread.

ALL original posts and comments must be substantive. (I’m looking for about a paragraph – not just “I agree.”)
