Riordan Manufacturing HRIS: System Design & Security
This paper examines the system design and security framework proposed for Riordan Manufacturing's Human Resources Information System (HRIS). The organization, a plastic injection molding producer, seeks to consolidate its HR tools into a single web-based application using a three-tier architecture. The paper outlines the data and process models—including Data Flow Diagrams—describes the relational database structure, and details the network topology connecting the company's LAN and WAN. It also addresses information security measures such as firewalls, intrusion detection and prevention systems, encryption, and disaster recovery planning, concluding with the network protocols required to support the new system.
- Introduction: Overview of Riordan HRIS design goals
- Process Design and Application Architecture: Web-based three-tier architecture and data modeling
- Security of the Information Systems: Firewalls, IDS, IPS, encryption, and disaster recovery
- Riordan Network System: LAN, WAN, servers, and network protocols
- Conclusion: Summary of design decisions and security tools

What makes this paper effective
- Clearly organizes a technical proposal into distinct functional sections—architecture, process modeling, security, and networking—making a complex subject easy to follow.
- Uses concrete acronyms and technical terminology (IDS, IPS, DFD, TCP/IP) appropriately, demonstrating familiarity with industry-standard concepts.
- Connects each design decision to a practical business benefit, such as explaining why web-based availability suits a multi-user HR environment.
Key academic technique demonstrated
The paper employs a layered explanatory strategy: it first defines each component (e.g., what a firewall or IDS does), then justifies its inclusion in the specific organizational context of Riordan Manufacturing. This definition-then-justification pattern is an effective technique for applied IT system design papers and helps readers with varying technical backgrounds follow the argument.
Structure breakdown
The paper opens with a brief introduction establishing the organizational context and scope. The second section covers application architecture and data/process modeling, referencing DFD figures. The third and longest section addresses information security across multiple layers—authentication, firewalls, IDS/IPS, encryption, disaster recovery, and security policy. The fourth section describes the network hardware and protocols. A short conclusion summarizes the key design and security decisions before the reference list.
Introduction
Riordan Manufacturing is an organization that produces plastic injection moldings. Its management has decided to take advantage of state-of-the-art technology to combine a variety of tools into a single application by developing a Human Resources Information System (HRIS). To implement the system effectively, the organization needs to develop a clear application architecture, process design, and security framework. This paper discusses the system design and security considerations for the Riordan HRIS.
