6. Computer Security Program Management 49 An organization's components may develop specialized expertise, which can be shared among components. For example, one operating unit may primarily use UNIX and have developed skills in UNIX security. A second operating unit (with only one UNIX machine), may concentrate on MVS security and rely on the first unit's knowledge and skills for its UNIX machine. Budget, the General Services Administration, the National Institute of Standards and Technology, and the National Telecommunications and Information Administration, provide information on computer, telecommunications, or information resources. This information includes security- related policy, regulations, standards, and guidance. A portion of the information is channelled through the senior designated official for each agency (see Federal Information Resources Management Regulation [FIRMR] Part 201-2). Agencies are expected to have mechanisms in place to distribute the information the senior designated official receives. Computer security-related information is also available from private and federal professional societies and groups. These groups will often provide the information as a public service, although some private groups charge a fee for it. However, even for information that is free or inexpensive, the costs associated with personnel gathering the information can be high. Internal security-related information, such as which procedures were effective, virus infections, security problems, and solutions, need to be shared within an organization. Often this information is specific to the operating environment and culture of the organization. A computer security program administered at the organization level can provide a way to collect the internal security-related information and distribute it as needed throughout the organization. Sometimes an organization can also share this information with external groups. See Figure 6.3. Another use of an effective conduit of information is to increase the central computer security program's ability to influence external and internal policy decisions. If the central computer security program office can represent the entire organization, then its advice is more likely to be heeded by upper management and external organizations. However, to be effective, there should be excellent communication between the system-level computer security programs and the organization level. For example, if an organization were considering consolidating its mainframes into one site (or considering distributing the processing currently done at one site), personnel at the central program could provide initial opinions about the security implications. However, to speak authoritatively, central program personnel would have to actually know the security impacts of the proposed change information that would have to be obtained from the system- level computer security program. Besides being able to help an organization use
