Critical infrastructure protection : significant challenges in safeguarding government and privately controlled systems from computer-based attacks by Joel C Willemssen( Book )

5 editions published in 2001 in English and held by 5 WorldCat member libraries worldwide

I am pleased to be here today to discuss efforts to protect federal agency information systems and our nation's critical computer-dependent infrastructures. Federal agencies, and other public and private entities, rely extensively on computerized systems and electronic data to support their missions. Accordingly, the security of these systems and data is essential to avoiding disruptions in critical operations, data tampering, fraud, and inappropriate disclosure of sensitive information. Further, as the Comptroller General stated in testimony last week, protecting against computer-based attacks on critical infrastructures is an important aspect of homeland security
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
