tional InfrastructureQuestion Description Given requirements:This assignment will be one of several throughout your PhD program that we use to help you prepare for the dissertation process. You’ll have to identify similar research, read the papers, and assimilate prior work into your own research. An annotated bibliography helps you develop and hone these research skills.Your paper will be an annotated bibliography, specifically focusing on the “Depth” topic (i.e. Defense in Depth) in the context of protecting National Infrastructure.You paper must be in correct APA format, use correct grammar, and will need to include at least seven (7) resources, ALL of which must:1) Be current. Published within the last few years.2) Be peer-reviewed.3) Relate directly to Defense in Depth in the context of protecting National Infrastructure.Remember that an annotation is not the same as an abstract. Abstracts are descriptive. Your annotations are to be evaluative and critical. Give me enough information for me to decide if I’m interested enough to read the paper, and also how you perceive the paper. Don’t go skimpy on these annotations, but DO NOT write too much here. Quality is far more important that quantity. This exercise is for each of you to demonstrate that you can identify, categorize, and digest multiple research papers.Every resource you choose must be peer reviewed. That means the paper must have undergone a formal peer review before being published in a journal or presented at a conference. You must ensure that your resources have undergone rigorous reviews. In most cases, you can find out the review process for a conference or journal by visiting the appropriate web site. Do not simply assume that a resource is peer reviewed – check it out.Here are a few URLs with additional information: (I strongly suggest that you look at these.
