CYBR 515 Case Study – Architecture Firm. Dalton, Walton, & Carlton, Inc. is an architecture firm with approximately 250 employees in four cities in a regional area. The main office is in Kansas City, Mo, which houses 100 of the employees. The main office is located in a suburb neighborhood where physical security is not considered a concern. Their IT infrastructure is as follows: · They primarily use Microsoft servers and PCs with a number of Mac computers used to perform design work.
They use Active Directory, have a Web Server for their Internet web site, four servers used as file shares (one in each office), four servers housing their architecture applications, a training server, five MS SQL database servers, and two Microsoft Exchange servers for email. · There are 20 Windows 2012 servers in the main office, twelve of which are virtualized on three physical servers. · System updates and patches are run from the main office. Most systems get Microsoft updates once a month, but some are missed. Also, most third party products (e.g., Adobe PDF & Flash) are not kept up to date. · Each satellite office has 3-4 servers for storing files and running local applications. · Each office has its own, decentralized wireless network connected to the production network. · Each employee has a desktop or laptop PC running Windows 7.
HR personnel have laptops for conducting interviews. · They outsource their email spam filter and all HR applications to two separate third party companies. · The network sits behind a gateway router and firewall. Antivirus is in use, but is not automatically updated across the company. Employees often work remotely and only use their login and password to gain access to the corporate systems. · There is a Director of IT who has a full time staff of 5 employees, one of which does security duties part time. There are a few known issues with their IT infrastructure and organization: · Recently, a number of PCs and office equipment has been stolen out of the office. · It’s at the data owner’s discretion as to whether or not to secure their data files or folders.
Many do not secure their files, while some lock them so only they have access. There have been rumors that customer data and intellectual property have been lost. · Two employees recently left your company and went to your biggest competitor, where they just landed a contract with your largest account. · Vendors are allowed access to the site and computers without authorization or supervision. · Onsite staff at each location provides IT support part time along with their other responsibilities.

Audit Report for Dalton, Walton, & Carlton, Inc.
Executive Summary
Dalton, Walton, & Carlton, Inc. (DWC) is an architectural firm with approximately 250 employees across four regional offices. The firm utilizes a mix of Microsoft and Apple products, operates under a decentralized network model, and has critical vulnerabilities in its IT infrastructure, particularly in the realms of physical and cybersecurity. An independent audit reveals the need for a comprehensive security strategy that encompasses personnel, processes, and technological enhancements. This report details the current state of security at DWC, highlights areas of concern, and provides actionable recommendations to mitigate risks.
Current IT Infrastructure
DWC's current IT infrastructure comprises Microsoft servers, PCs, and a few Mac computers. The organization operates primarily through Microsoft services, utilizing Active Directory for identity management alongside various servers for email, web services, and application hosting. Moreover, the company engages in outdated practices for patch management, decentralized wireless networks, and inadequate employee training on security protocols.
1. Physical Security: The main office resides in a low-risk suburb, relying on the assumption that physical security poses minimal concern. However, recent incidents of equipment theft highlight this oversight.
2. System Updates: DWC has a sporadic update mechanism, performing monthly updates for Microsoft products but neglecting many third-party software solutions, leading to potential vulnerabilities.
3. User Authentication: Employees primarily use weak authentication methods, such as generic company passwords for reset protocols, which endangers confidential company data.
4. Data Security: With decentralized file access policies, employees often neglect securing sensitive data, risking the loss of customer information and intellectual property.
5. Outsource Services: The firm relies heavily on third-party vendors for email spam filtering and HR applications, which may expose them to additional security risks if not prudently managed.
Key Issues Identified
1. Unauthorized Access: The lack of strict supervision and authorization for vendor access weakens the firm’s security posture.
2. Employee Terminations: The recent departures of employees to competitors raise concerns regarding intellectual property theft and data leaks.
3. Weak Password Policies: The use of a generic password for resets can allow unauthorized users easy access to secure areas of the network.
4. Inconsistent Antivirus Updates: The failure to automatically update antivirus software amplifies risks from malware or ransomware.
5. Physical Equipment Theft: The theft of PCs and office equipment indicates inadequate physical security measures.
Recommendations
Based on the audit findings, the following recommendations are proposed:
1. Enhance Physical Security: Implement improved physical security measures, such as access cards, CCTV surveillance, and controlled vendor access protocols.
2. Regular System Audits and Updates: Establish a strict update schedule that includes both operating systems and any third-party applications. Automate this process wherever possible to avoid missed updates.
3. Strengthen Authentication Mechanisms: Implement a multi-factor authentication process to enhance user verification. Additionally, dispel the use of generic passwords and enforce unique, robust passwords for all employees.
4. Implement Data Protection Policies: Formulate and enforce a data classification scheme that mandates all employees secure sensitive files. Regular training on data handling and security best practices should be conducted to ensure compliance.
5. Outsource Security Management: Given the reliance on third-party services, DWC should establish agreements with these vendors that incorporate security clauses for managing risks effectively.
6. Employee Exit Protocols: Create a standardized procedure for employee terminations that includes a review of access privileges, data retention policies, and immediate revocation of access to company systems.
7. Regular Training Programs: Conduct ongoing employee training to raise awareness about cybersecurity best practices, phishing attacks, and social engineering tactics.
8. Incident Response Plan: Develop an incident response strategy that outlines steps to take in case of data breaches or system failures. The plan should include detailed roles and responsibilities to mitigate damages.
9. Utilize Network Segmentation: Employ network segmentation to limit access to sensitive data and to enhance security by keeping different types of traffic isolated.
10. Conduct a Risk Assessment: Perform an in-depth risk assessment to identify further vulnerabilities, assess the potential impact of threats, and prioritize remediation actions.
Conclusion
Dalton, Walton, & Carlton, Inc. stands at a critical juncture in strengthening its cybersecurity posture. The recommendations presented above serve to fortify the IT infrastructure against present and future threats while enhancing overall operational resiliency. It is crucial to adopt a culture of security awareness within the organization, particularly as employee mobility and decentralized access become prevalent.
Implementing these changes will not only protect sensitive data and intellectual property but also enable DWC to build trust with clients and stakeholders, fostering a secure and conducive working environment.
