COM520 Written Assignment 8 Case Scenario for Rationale Ken 7 Windows Limited is a manufacturer of Windows for residential and commercial builders. Ken 7 Windows Limited carries a variety of Windows and related products. It supplies builders with all of the tools and supplies to install finished Windows in any type of building. Ken 7 Windows Limited has just purchased a new enterprise resource planning (ERP) software package to help control costs and increase both quality and customer responsiveness. The ERP software collects and stores information including: • Raw material costs • Labor costs • Materials and labor requirements for products • Purchasing requirements Ken 7 Windows Limited has identified six basic roles for users in the new ERP software: • Administrators—maintain ERP data and system operation. • Planners—run planning software and generate requirements reports. • Shop Floor users —enter operational data (receiving, shipping, and product progress during manufacturing). • Managers—manage department personnel. • Purchasing users—generate purchasing documents based on planning requirements. • Accounting users—maintain cost and accounting data.

Access controls limit what users or roles can do with different types of data. For example, consider the following types of data: • Cost information—raw materials and labor costs, including the cost of finished goods. • Manufacturing details—cost, amount of labor, and time required to produce finished goods. • Purchasing requirements—rules for determining when raw materials, components, or supplies should be purchased. Through access control: • Cost information can be viewed only by Accounting users. • Manufacturing details can be viewed only by Shop Floor users. • Purchasing requirement can be viewed only by Purchasing users. During the analysis phase of the ERP implementation, Ken 7 Windows Limited raised concerns about users being able to access restricted data. • Accounting users are able to login to shop floor computers. • Purchasing users are able to access human resource (HR) applications and data.

The ERP implementation team suggested the following access control measures to protect restricted data. • Create an organizational unit (OU) in Active Directory for shop floor computers. • Deploy Group Policy Objects (GPOs) to restrict shop floor users to the shop floor OU. • Define data access controls in the ERP software to deny access for all non-HR users to restricted data. Implementation of several access control measures helped Ken 7 Windows Limited to restrict the data access. Hence access control and authentication is important, as it helped Ken 7 Windows Limited in reducing costs and increasing profits.

Paper for above instructions

In the context of implementing enterprise resource planning (ERP) software at Ken 7 Windows Limited, securing web browsers and web servers is of paramount importance. This assignment will articulate comprehensive policies aimed at ensuring security for both of these pivotal software applications, addressing functions this software should allow and prohibit, as well as necessary controls and validation mechanisms.

Policy 1: Web Browser Security Policy

Type of Application Software

Web Browser Software

Description of Functions This Software Should Allow

- Secure Browsing: The web browser should facilitate secure HTTP transactions (HTTPS) to protect data in transit (Garfinkel & Smetters, 2006).
- Content Filtering: Enabling security features to block potentially harmful content such as malware, phishing sites, and advertisements (Santos & Oliveira, 2016).
- User Authentication: Supporting multi-factor authentication (MFA) for enhanced security during login processes (Fouad, 2018).

Description of Functions This Software Should Prohibit

- Script Execution: Automatic execution of scripts from untrusted sources, which might lead to cross-site scripting (XSS) attacks (Dhanjani et al., 2010).
- Plugin Installation: Allowing the installation of unverified or unauthorized plugins, which can introduce vulnerabilities (Wise, 2009).
- Access to Sensitive Sites: Prohibiting access to unauthorized or non-work related websites, which can compromise workplace security (Kumar et al., 2015).

Known Vulnerabilities Associated with Software

- Phishing Attacks: Attackers exploit social engineering to steal user credentials (Jagatic et al., 2007).
- Cross-site Scripting (XSS): Unsanitized input allows attackers to inject malicious scripts (W3C, 2007).
- Malware infections: Through browser vulnerabilities that allow for the downloading of malicious software (Fernandez et al., 2012).

Controls Necessary to Ensure Compliance with Desired Functionality

- Regular Updates: Implementing automatic updates to ensure the latest security patches are applied (W3C, 2007).
- Content Security Policy (CSP): Utilizing CSP headers to restrict resources that can be loaded on the web pages (Fletcher, 2017).
- User Training: Conducting training sessions for employees on recognizing phishing attempts and safe browsing practices (Chung, 2016).

Method to Assess Security Control Effectiveness

- Security Audits: Conducting regular security audits of the browsers used and compliance with security policies (ISO/IEC 27001:2013).
- Penetration Testing: Engaging in simulated attacks to identify vulnerabilities and determine if browser security measures are effective (Harris, 2009).
- User Feedback: Gathering input from users regarding browser performance and any security incidents encountered (Bennett & O’Brien, 2017).
