IT Systems Architecture
You are a senior-level employee and you must tailor your deliverables to suit your audience: the
leadership of the organization. You may choose to use a fictitious organization, or model your
organization on an existing organization, including proper citations. Leadership is not familiar with the architecture of the IT systems, nor are they familiar with the types of
threats that are likely or the security mechanisms in place to ward off those threats. You will provide this
information in tabular format. Before you begin, review some material on information security. These resources will help you complete
the network security and vulnerability threat table.
•LAN security

Now you’re ready to create your table. Include and define the following components of security in the
architecture of your organization, and explain if threats to these components are likely, or unlikely:
•LAN security
•identity management •physical security
•personal security
•availability
•privacy Next, review the different types of cyberattacks described in the following resource: cyberattacks. As
you’re reading take note of which attacks are most likely to affect your organization. Then list the
security defenses you employ in your organization to mitigate these types of attacks. Include this
information in your Network Security and Vulnerability Threat Table. LINK below

Then, in your report, describe the cryptographic mechanisms available to your organization, and
describe the benefits and risks of each. Also describe your file encryption tools, and provide the methods
and results of encrypting files in your organization. Include this information in your deliverable to
leadership. Data Hiding Technologies
Provide your organization with a brief overview of each. Encryption Technologies
1.Shift / Caesar cipher
2.Polyalphabetic cipher
3.One time pad cipher/Vernam cipher/perfect cipher
4.Block ciphers
5.triple DES
6.RSA
7.Advanced Encryption Standard (AES)
8.Symmetric encryption
9.Text block coding Data Hiding Technologies
1.Information hiding and steganography
2.Digital watermarking
3.Masks and filtering These descriptions will be included in the network security vulnerability and threat table for leadership. Creating the Network Security Vulnerability and Threat Table
Using the information you've gathered from the previous steps, prepare the network security
vulnerability and threat table, in which you outline the following:
•security architecture of the organization
•the cryptographic means of protecting the assets of the organization
•the types of known attacks against those types of protections means to ward off the attacks Create your Network Security Vulnerability and Threat Table, and include it in your submission to the
organization. Please refer to this threat table template for guidance on creating this document.

Smart cards use encryption chips to identify the user, their identity, role, and sometimes use their
personal identifiable information (PII). Two examples of smart cards are the federal government’s use of
common access cards (CACs), and the financial sector’s use of encryption chips in credit cards. You have completed your threat table, and you've decided that you want to modernize the access
control methods for your organization. To that end, you read the following resources to gather some
background information on access control and the various encryption schemas associated with the
Common Access Card (CAC):
•Access control

8, 2016, from http://www.cac.mil/common-access-card/cac-security/ You plan to deploy CAC to the company and you are tasked with devising that CAC deployment strategy,
which includes the cryptographic solutions used with the CAC. In the Common Access Card Deployment Strategy final deliverable, describe how identity management
would be a part of your overall security program and your CAC deployment plan: Create your Common Access Card Deployment Strategy and include it in your submission to the
organization. The Email Security Strategy
After completing the CAC, your next step is to build the Secure Email Strategy for the organization. You
will present this tool to your leadership. Provide an overview of the types of public-private key pairing, and show how this provides
authentication and nonrepudiation. You will also add hashing, and describe how this added security
benefit ensures the integrity of messaging. Begin preparing your strategy by reviewing the following resources that will aid you in becoming well
informed on encryption technologies for e-mail:
•Public Key Infrastructure (PKI)

Then start developing your strategy. Define these strong encryption technologies as general principles in
secure email:
Pretty Good Policy (PGP algorithm) •GNU Privacy Guard (GPG)
•Public Key Infrastructure (PKI)
•Digital signature
•Mobile device encryption (e.g., iOS encryption and Blackberry encryption) In your report, also consider how the use of smart card readers tied to computer systems might be
beneficial in the future enhancements to system and data access protection. This may help you define
long-term solutions for your leadership. Leadership does not know the costs and technical complexity of these email encryption strategies. To
further their understanding, compare the complexities of each in relation to the security benefits, and
then make a recommendation and a deployment plan. The deliverables for this project are as follows:
1. Create a single report in Word document format. This report should be about 10 pages long, doublespaced, with citations in APA format*****IN TEXT CITATION IS A MUST. Page count does not include
diagrams or tables. The report must cover the following:
â—¦network security and threat table
â—¦Common Access Card deployment strategy
â—¦e-mail security strategy
