<div>I am totally lost........Would the Noninterference Model allow Don to work on the same production code that the staff is currently using, and the staff wouldn't be affected by his changes?</div>
<div> </div>
<div>Please help me understand.</div>

<div>Thanks,<br><br></div>

<div>Don should not be developing/working on code that's in production. Period. If I had to decide on a certain security model, I'd fail this question for sure because him working on code that staff members are affected by is a MAJOR distractor within this paragraph.</div>

<div>Hi,</div>
<div> </div>
<div>This question is from <span>Shon</span> H's CISSP V4 Quiz Engine. I <span>immediatly</span> thought that this fall</div>
<div>into a certain security model based on a key statement here but I was wrong. Anyway you guys could dissect this ... </div>
<div> </div>
<div><font face="Arial" size="2">Don is a senior manager of an architectural firm. He has just found out that a key contract was renewed, allowing the company to continue developing an operating system that was idle for several months. Excited to get started, Don begins work in the operating system privately, but cannot tell his staff until the news is announced publicly in a few days. However, as Don begins making changes in the software, various staff members notice changes in their connected systems, even though they work in a lower-security level. What kind of model could be used to ensure this does not happen?</font></div>
