our Microsoft® Windows® 2000-based office network has three domains: ALPHA, BETA, and OMEGA, all in the same Active Directory tree.

Required result: You must provide access to some users with accounts in the ALPHA domain to some resources in the OMEGA domain, but users in the OMEGA domain should not have access to resources in the ALPHA domain.

Optional result: If possible, changes to the ALPHA users’ accounts should be reflected in the accounts they use to access OMEGA resources.

Proposed solution: Add the ALPHA users to a global group in ALPHA, and add that group to a local OMEGA group that has permissions to the required resources. Based on your goals and your actions, determine which of the following statements is true and explain:

• You accomplished both your required result and your optional result.
• You accomplished your required result, but not your optional result.

You will need at least five scholarly references for the paper, to back up your assertions or  ideas.  You are free to use as many other references as needed, as long  as you have five scholarly sources properly included.  

Review information assurance policy templates  via the SANS policy template site  (https://www.sans.org/security-resources/policies) and select a template  of your choice; such as the General / Acceptable Encryption Policy to  download either the doc or pdf file. Utilize the downloaded template,  from the SANS Policy website, and the Course Project Grading Rubric as a  guide to provide a 5-page write-up highlighting key components that  should be included during the development of an information assurance  policy. Key components will include the following:

– Overview

– Purpose

– Scope

– Policy Compliance

– Related Standards

– Definitions

– Terms

Discuss each component and the specific information that can be included within each section of the policy. 

Support your paper with five  resources.  In addition to these specified resources, other appropriate  scholarly resources, including older articles, may be included.

Length:  5 pages not including titles page(s) and reference pages

Your  paper should demonstrate thoughtful consideration of the ideas and  concepts that are presented in the course and provide new thoughts and  insights relating directly to this topic. Your response should reflect  scholarly writing and current APA standards.

Please follow  the attached Reflective Article Example Format, using whatever level one  headers you like, that makes sense.  Please keep in mind that you will  not have an Article Reference header at the top of the paper, but you  should still have a references section at the end.  

Be sure to have a title page with running head and do not use a real company or organization name, make one up.

The purpose of  this paper is to develop an information assurance policy.  It should  read like real guidance; you would deliver to your future or present  company someday.  The citations should be used to give clarity or  credibility to a statement you are making, do not just cite something  because you saw them say it that way or format their paper that way.   Make a statement, then back it up with a citation from a scholarly  source.  Be sure to cover all that is described in the instructions for  the assignment.  It may be helpful to search the library for scholarly  sources that describe what is in an “Information Assurance Policy,“  “Information Security Plan” or “Information Security Policy.”

You  might also want to search in the library for “Information Assurance  Policy “and “Security Plan” and look for relevant examples, but be  careful to not copy/paste, cite all borrowed ideas and use scholarly  sources for at least 5 of those citations.

An ANOVA is when we want to run a means test on more than 2 groups. However, the same basic structure of the hypothesis testing that we have done remains.

Using the hockey data, test if there is a difference between the true average number of goals scored by the different divisions. Second, test if there is a difference between the actual mean number of goals allowed by teams of different quality (where teams with at least 100 points is the top tier, those with 90-99 are the middle tier, and those with less than 90 make up the bottom tier).

If either of these tests show significance, run a multiple comparisons test among the groups. (Note that this is essentially the two sample testing we just did but with an adjustment to ensure that we don’t have inflated error probabilities.) Use a 0.05 significance level for all tests.

As you do this for your own data set, ensure that at least one of the two problems shows significance and requires pairwise comparisons. Unless impossible to avoid, do not use more than 4 groups — there’s nothing that says you can’t, but it’ll make your report much more tedious. Also note that if you only have 2 groups, that’s a two sample independent mean test and not an ANOVA; we did that last assignment, so ensure that you have at least 3 groups in your analysis.
