Private (EPA) Databases. The U.S. EPA maintains a Hst of approximately 600 current information systems, as weU as some of the models and databases used within the organi2ation. The Hst is pubHshed in Information Systems Inventoy (ISI) which is updated yearly and maintained by the Information Management and Services Division of the Office of Information Resources Management (109). ISI Hsts the system name and acronym, system level, responsible organi2ation, contact person, legislative authorities, database descriptors, access information, hardware and software, system abstract, and keywords. 

Computers. A certain number of personal computers are necessary for report generation and regulatory submission preparation. In addition, these may be useful for record keeping, depending on the type of stability information system that the company chooses to use. Alternatively, if the information system is intended to be accessible (read only) to many users, it may be more efficient to develop a local area network of mini-computers. The size of the database will help determine the nature of the software/hardware configuration used for this function. 

Cyber security Protection of critical information systems including hardware, software, infrastructure, and data from loss, corruption, theft, or damage. 

Network (including communication links). Legacy systems hardware and software have very limited security capabilities, and the vulnerabilities of contemporary systems (based on modern information technology) are publicized. Wireless and shared links are susceptible to eavesdropping and data manipulation. 

Specific guidelines for laboratory information systems include regulahons for computer conhgurahon, procedure manuals, system security, data entry/reports/ retrieval, hardware and software, and system maintenance. 

For input, storage, manipulation, and output within computer-based systems, a representation of the chemical substance must be selected. The selection of a particular representation scheme for an information system is based on the size of the files to which it applies, the functions to be performed, the available hardware and software, and the desired balance between... 

There is sufficient information available to enable the computer system (hardware and software) and associated instrumentation to be operated and maintained safely and effectively. 

Gather the requirements for the systems including functional (e.g. operational checks) requirements, nonfunctional (e.g., coding standards) requirements, users, company-wide regulatory compliance (e.g., Part 11 technical control), safety, process, and other applicable requirements Characterize information, assess its value to the organization, and incorporate information quality as part of the project plan Conduct a system (hardware, software, and process) risk analysis. New requirements may be found as the result of the risk analysis. Any new requirements must be documented in the requirements specification deliverable... 

Security configuration management (all listed implementation features must be present) The organization to implement the necessary measures, practices, and procedures for the security of information systems Documentation Hardware/software installation and maintenance review and the testing of the security features System inventory Security testing Virus checking... 

Regardless of the age or cost of information and hardware systems, all require some form of maintenance. Maintenance involves updating, changing, or improving the existing system. The goal is to continually improve the systems functionality and usability while minimizing the time that it is nonoperational (downtime). Ideally, information systems should require only minor or routinely scheduled maintenance. There are two kinds of maintenance or downtime scheduled... 

Any information system consists of hardware, software, communications equipment, environmental control equipment, documentation and staff. It manages, i.e., processes, transmits and stores information. All of the above are called the system assets , and must be protected. 

The critical information infrastructure (CII) is a subset of the critical infrastructure, composed of the totality of interconnected computers and networks and their critical information flows [8]0, comprising therefore a vast range of components and systems, extending from hardware (satellites, routers), to software (operating systems, Internet protocols, databases), to data (DNS tables), to the processes and operations applied for running them [16]0. The CII includes typical information systems and telecommunications services, but increasingly now industrial systems (as for instance, the remote control of installations). 

Device Manager Used to view and modify information about system hardware. We will look at this more in the Hardware section. 

C. The lO.SYS file allows the rest of the operating system and its programs to interact directly with the system hardware and the system BIOS. A part of this file s code is hardware drivers for common devices (such as serial and communication ports and disk drives). See Chapter 13 for more information. 

Enterprise-wide information systems, by their definition, must be networked. The physical hardware and configuration supporting the applications must be specified, which is a combined effort between the hardware supplier and the internal IS function. 

If not already present, the Y2k experience should have produced a complete overview of hardware, software and embedded systems. This should be incorporated in an information system that can serve as a powerful tool for the infrastructure architect and the operational manager. 

Mr. Salvage is currently the information systems business manager with CSR of Australia and is leading the company s ERP implementation with management and technical responsibility for software development and hardware infrastructure. Having spent 10 years with ICI and Zeneca, installing pharmaceutical process control and information systems, Mr. Salvage has in recent...
