Critical infrastructure protection : significant challenges in developing analysis, warning, and response capabilities : statement of Robert F.

Federal agencies, and other public and private groups, rely extensively on computer systems and electronic data. The security of these systems and data is essential to avoiding disruptions in critical operations and preventing data tampering, fraud, and inappropriate disclosure of sensitive information. However, federal computer systems contain weaknesses that continue to put critical operations and assets at risk. In particular, deficiencies exist in entitywide security programs that are critical to agencies' success in ensuring that risks are understood and effective controls are implemented. Many efforts have been undertaken to implement the nationally critical infrastructure protection strategy outlined in Presidential Decision Directive (PDD) 63. However, progress in key areas has been limited. Although outreach efforts by many federal entities to establish cooperative relationships with and among private and other nonfederal entities have raised awareness and prompted information sharing, efforts to perform substantive analyses of sector-wide and cross-sector interdependencies and related vulnerabilities have been limited. A major impediment to implementing the strategy outlined in PDD 63 is the lack of a national plan that clearly spells out the roles and responsibilities of federal and nonfederal entities and defines interim objectives

DOD's standard procurement systems : continued investment has yet to be justified by Joel C Willemssen( Book )

4 editions published in 2002 in English and held by 1 WorldCat member library worldwide

The Department of Defense (DOD) lacks management control of the Standard Procurement System (SPS). DOD has not (1) ensured that accountability and responsibility for measuring progress against commitments are clearly understood, performed, and reported; (2) demonstrated, on the basis of reliable data and credible analysis, that the proposed system solution will produce economic benefits commensurate with costs; (3) used data on progress against project cost, schedule, and performance commitments throughout a project's life cycle to make investment decisions; and (4) divided this large project into a series of incremental investment decisions to spread the risks over smaller, more manageable components. GAO found that DOD lacks the basic information needed to make informed decisions on how to proceed with the project. Nevertheless, DOD continues to push forward in acquiring and deploying additional versions of SPS. This testimony summarizes a July report (GAO-01-682)

Electronic government : success of the Office of Management and Budget's 25 initiatives depends on effective management and oversight by Joel C Willemssen( )

1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide

A key element of the President's Management Agenda is the expansion of electronic government (e-government) to enhance access to information and services, particularly through the Internet. In response, the Office of Management and Budget (OMB) established a task force that selected a strategic set of initiatives to lead this expansion. GAO previously reviewed the completeness of the information used for choosing and overseeing these initiatives, including business cases and funding plans. E-government offers many opportunities to better serve the public, make government more efficient and effective, and reduce costs. To achieve these goals, the 25 e-government initiatives selected by OMB's Quicksilver task force focus on a wide variety of services, aiming to simplify and unify agency work processes and information flows, provide one-stop services to citizens, and enable information to be collected on line once and reused, rather than being collected many times. For example, Recreation One-Stop is a Web portal for a single point of access to information about parks and other federal, state, and local recreation areas. Other initiatives are being pursued that do not necessarily rely on the Internet, such as the e-Payroll initiative to consolidate federal payroll systems. GAO's review of the initial planning documents for the initiatives highlights the critical importance of management and oversight to their success. Important aspects--such as collaboration and customer focus--had not been addressed in early program plans for many of the projects, and major GAO's review of the initial planning documents for the initiatives highlights the critical importance of management and oversight to their success. Important aspects--such as collaboration and customer focus--had not been addressed in early program plans for many of the projects, and major uncertainties in funding and milestones were not uncommon. As shown by GAO's comparison of the content of the initiatives' business cases with best practices, all the business cases included key information, but many elements were missing. In particular, fewer than half addressed collaboration and customer focus, despite the importance of these topics to e-government strategy and goals. Similarly, the accuracy of estimated costs in the funding plans was questionable: between May and September 2002, these estimates for 12 of the initiatives changed significantly--by more than 30 percent. Accurate cost, schedule, and performance information is essential to ensure that projects are on schedule and achieve their goals
National Oceanic and Atmospheric Administration: National Weather Service Modernization and Weather Satellite Program( )

1 edition published in 2000 in English and held by 0 WorldCat member libraries worldwide

We appreciate the opportunity to join in today's hearing to discuss our work in two areas that are the responsibility of the National Oceanic and Atmospheric Administration (NOAA). At your request, we will discuss the status of the National Weather Service (NWS) systems modernization and the National Environmental Satellite, Data, and Information Service's Geostationary Operational Environmental Satellite (GOES) program. In brief, although NWS is nearing completion of its systems modernization effort, it still faces important challenges. During the coming year, NWS plans to finish commissioning' the Advanced Weather Interactive Processing System (AWIPS), the final system of the modernization. At the same time, NWS is developing additional AWIPS system capabilities to be implemented in the future. According to NWS, these additional capabilities are needed for AWIPS to improve radar and satellite data processing and to provide weather forecasters with a full range of interactive forecasting techniques. The agency is also developing a systems architecture to provide a blueprint for future systems acquisitions. Regarding the GOES program, NOAA continues to deploy weather satellites to ensure adequate satellite coverage. However, because of unexpected problems, satellite coverage is currently at risk and will remain so until a new satellite is successfully launched. NOAA plans to launch the new satellite in May 2000. To ensure continued satellite coverage beyond the current satellite series, NOAA is planning for the program's near- and long-term future. The approach we used to perform this work-our objectives, scope, and methodology-are provided in appendix I
