Nonrepudiation is the ability to have proof that a message originated from a specific party. In an email system, for example, nonrepudiation mechanisms ensure that every message can be confirmed as coming from a specific party or sender.

Answer the following question(s):

1. Do you think nonrepudiation falls under one of the tenets of the C-I-A triad (confidentiality, integrity, and availability)? Why or why not?

2. Is the C-I-A triad adequate when selecting controls for a Windows system? Why or why not?

Security experts recommend using a multilayered defense strategy. A multilayered defense puts multiple controls in place to protect computer system, networks, and other resources.

Answer the following question(s):

1. Does a multilayered defense guarantee that attacks will not be successful? Why or why not?

Project Part 1: Active Directory Recommendations

Scenario

Assume you are an entry-level security administrator working for Always Fresh. You have been asked to evaluate the option of adding Active Directory to the company’s network.

Tasks

Create a summary report to management that answers the following questions to satisfy the key points of interest regarding the addition of Active Directory to the network:

1. System administrators currently create users on each computer where users need access. In Active Directory, where will system administrators create users?

2. How will the procedures for making changes to the user accounts, such as password changes, be different in Active Directory?

3. What action should administrators take for the existing workgroup user accounts after converting to Active Directory?

4. How will the administrators resolve differences between user accounts defined on different computers? In other words, if user accounts have different settings on different computers, how will Active Directory address that issue? (Hint: Consider security identifiers [SIDs].)
