Software Specifications and Design computer science assignment help

I need three changes in my research paper. I mention them below

1. In page 6,  3.4 Introduction 5th line I need to write about 

explain what authors meant by “topology of an operating environment”?

2. In page 9,  3.9 state space reduction heuristics 5th line I need to write about                                                                Explain how the analysis is reactive and not proactive?

3. In page 20, 7.0 Discussion after the table I need to write about 

Talk about what prevention techniques (paper 3), and early detection techniques (paper 1 and 2 and main); discuss detection techniques have 3 similar models 

Here’s an outline for the Discussion section:

Prevention

-Use requirements patterns and a feature diagram to show relationships between patterns and their tradeoffs

Early detection

-Model what is being protected – asset model (UML), topology model (ambient calculus)

-Model the system behavior – fuzzy causal network, labeled transition system

-Model the security objectives – goal model, computational tree logic

-If the set of assets/things being protected changes, the system behavior is affected and the security objectives are re-checked to see if security will be violated

Main paper summary: Define topology, why reactive and not proactive?

I attach my research paper and the  4 papers related to the research below.
