SE571 Course Project: Security Assessment and Recommendations
Aircraft Solutions (AS) is a recognized leader in the design and fabrication of component products and services for companies in the electronics, commercial, defense, and aerospace industry. Located in Southern California, AS has a dedicated, trained workforce and maintains a large capacity plant and extensive equipment to meet customer requirements. Much of the equipment is automated to increase production while reducing costs. The company's workforce has a large skill base: design engineers, programmers, machinists, and assembly personnel to work its highly-automated production ...view middle of the document...
The system administrators are members of an information technology (IT) group within the organization. They are responsible for selecting and installing hardware, software and related upgrades, implementing information security measures, and maintaining support to ensure the manufacturing execution system is working properly. They also are heavily involved in training the workforce to use and interact with the information systems. Their duties include planning for and responding to emergency events such as power outages, attempts at cyber-attack, and natural disasters.
The users at AS are employees, customers, suppliers, and contractors who need to access the company network. System access by users at different levels of the network is set strictly on a need-to-know basis. Controls are in place to secure confidential and proprietary information from unauthorized access. Users are responsible for entering and processing data and information, such as generating reports to be used for decision-making.
AS uses Business Process Management (BPM) to handle end-to-end processes that span multiple systems and organizations. The BPM system is designed to connect customers, vendors, and suppliers to share information and maintain a timely business dialogue. BPM also aligns internal business operations with IT support to maintain production in support of customer requirements.
Business process effectiveness begins with the IT organization. Customer data such as project information, computer-aided design and development models are sorted and stored in designated servers. The Design Engineering department is responsible for reviewing the electronic models, interacting with the customer and making necessary modifications with customer approval, then placing them in an Engineering Release (ER) directory for programming. As soon as these electronic models are released, programmers use them to create production programs. All final programs must be thoroughly verified for accuracy before releasing to the Proof For Production (PFP) directory for manufacturing to make the production first article.
From the production floor, machinists download PFP programs directly to their DCNC (Direct Computer Numerical Control) machines for execution. After any further processing, completed products are inspected for verification to customer requirements, then they are moved to the Shipping department for delivery. A continuous improvement and feedback loop system is in used to correct any deficiencies in the production process.
The BPM system is capable of handling multiple projects simultaneously across every department of the company. BPM is set up to manage all aspects of business operations, including accounting, human resources, sales and marketing, and compliance activities concurrently.
