Firewall Change Control Process
Imagine you finally have your new firewall up and running. After much consultationwith users, its governing rules are in place and functioning properly. However, you receive two requests for changes in the firewall during the first week:
1. The head of marketing would like the local newspaper to havedaily network access to downloademployment ads from the marketing file server.
2. The firewall has broken the head of research and development’s connection to a favorite website. He wants his access back and has asked for your help.
Discuss how you would respond to these requests. What kinds of procedures are needed to ensure that proper requests are implemented and inappropriate requests are denied?

Discussion 1 – 1 page
Characteristics of Access Control and Authentication
Most IT and IAS professionals are familiar with the basic concepts surrounding authentication and access control systems. There are fewer professionals who have taken the time to consider the more granular characteristics of these controls and the options that are available for differentiation, selection, and implementation.
Use the study materials and engage in any additional research needed to fill in knowledge gaps. Discuss the following:
Describe the combination of authentication and access controls that you believe best balance cost, complexity, and security. Support your position.
Explain how domain trusts, isolation technologies, and the separation and organization of those technologies can support a network security strategy.
Describe an example of how encapsulation or encryption contribute to a specific access control or authentication solution.

Assignment 1 – 2 pages
Access Control and Authentication Methods and Models
Access controls and authentication systems are some of the most ubiquitous of all information security controls. Too often these controls still hinge on poorly implemented and managed password strategies. However, there is a wide array of technologies and tools available to organizations seeking to secure their information assets. As governments create more regulations and organizations experience larger and more widely publicized breaches of personal data, these organizations may more frequently turn to additional layers of controls to supplement traditional access and authentication strategies.
Use the study materials and engage in any additional research needed to fill in knowledge gaps. Write a 23 page paper that covers the following topics:
Describe your lab experiences related to access controlsand authentication systems available for use in organizations to protect information assets.
Analyze the security characteristics of commonly used file systems.
Explain how access control lists play a role in a layered network security strategy.
Explain the security benefits available through domain separation, process isolation, resource encapsulation, and least privilege.
At the end of your paper, also include lab screenshots from u01v1 and u02v1.
Additional Requirements
Your assignment should also meet the following requirements:
Written communication:Written communication is free of errors that detract from the overall message.
APA formatting:Your paper should demonstrate current APA style and formatting.
Number of resources:Include a minimum of threeresources, appropriately cited throughout your paper and in your reference list.
Suggested length:23 pages, typed and double-spaced, not including the title page and reference list.
Font and font size:Times New Roman, 12 point.
