Cybersecurity: Continued Efforts Are Needed to Protect Information Systems Form Evolving Threats


Book Description

Pervasive and sustained cyber attacks continue to pose a potentially devastating threat to the systems and operations of the fed. government. In recent months, fed. officials have cited the continued efforts of foreign nations and criminals to target government and private sector networks; terrorist groups have expressed a desire to use cyber attacks to target the U.S.; and press accounts have reported attacks on the Web sites of government agencies. This statement describes: (1) cyber threats to fed. information systems and cyber-based critical infrastructures; (2) control deficiencies at fed. agencies that make these systems and infrastructures vulnerable to cyber threats; and (3) opportunities that exist for improving fed. cybersecurity.

CYBERSECURITY: Continued Efforts Are Needed to Protect Information Systems From Evolving Threats


Book Description

As computer technology has advanced, federal agencies have become dependent on computerized information systems to carry out their operations and to process, maintain, and report essential information. Virtually all federal operations are supported by automated systems and electronic data, and agencies would find it difficult, if not impossible, to carry out their missions, deliver services to the public, and account for their resources without these information assets. Information security is thus especially important for federal agencies to ensure the confidentiality, integrity, and availability of their information and information systems. Conversely, ineffective information security controls can result in significant risk to a broad array of government operations and assets. Examples of such risks include the following: Resources, such as federal payments and collections, could be lost or stolen. Computer resources could be used for unauthorized purposes or to launch attacks on other computer systems. Sensitive information, such as taxpayer data, Social Security records, medical records, intellectual property, and proprietary business information, could be inappropriately disclosed, browsed, or copied for purposes of identity theft, espionage, or other types of crime. Critical operations, such as those supporting critical infrastructure, national defense, and emergency services, could be disrupted. Data could be added, modified, or deleted for purposes of fraud, subterfuge, or disruption.

Effective Model-Based Systems Engineering


Book Description

This textbook presents a proven, mature Model-Based Systems Engineering (MBSE) methodology that has delivered success in a wide range of system and enterprise programs. The authors introduce MBSE as the state of the practice in the vital Systems Engineering discipline that manages complexity and integrates technologies and design approaches to achieve effective, affordable, and balanced system solutions to the needs of a customer organization and its personnel. The book begins with a summary of the background and nature of MBSE. It summarizes the theory behind Object-Oriented Design applied to complex system architectures. It then walks through the phases of the MBSE methodology, using system examples to illustrate key points. Subsequent chapters broaden the application of MBSE in Service-Oriented Architectures (SOA), real-time systems, cybersecurity, networked enterprises, system simulations, and prototyping. The vital subject of system and architecture governance completes the discussion. The book features exercises at the end of each chapter intended to help readers/students focus on key points, as well as extensive appendices that furnish additional detail in particular areas. The self-contained text is ideal for students in a range of courses in systems architecture and MBSE as well as for practitioners seeking a highly practical presentation of MBSE principles and techniques.




Cybersecurity


Book Description

Federal laws and policy have assigned important roles and responsibilities to the Department of Homeland Security (DHS) and the National Institute of Standards and Technology (NIST) for securing computer networks and systems. DHS is charged with coordinating the protection of computer-reliant critical infrastructure--much of which is owned by the private sector-and securing its own computer systems, while NIST is responsible for developing standards and guidelines for implementing security controls over information and information systems. GAO was asked to describe cybersecurity efforts at DHS and NIST-including partnership activities with the private sector-and the use of cybersecurity performance metrics in the federal government. To do so, GAO relied on its reports on federal information security and federal efforts to fulfill national cybersecurity responsibilities. GAO has previously made about 30 recommendations to help DHS fulfill its cybersecurity responsibilities and resolve underlying challenges. In addition,




Cybersecurity


Book Description

"The federal government faces an ever-evolving array of cyber-based threats to its systems and information. Further, federal systems and networks are inherently at risk because of their complexity, technological diversity, and geographic dispersion, among other reasons. GAO has designated the protection of federal information systems as a government-wide high-risk area since 1997. In 2001, GAO introduced strategic government-wide human capital management as another area of high risk. A key component of the government's ability to mitigate and respond to cyber threats is having a qualified, well-trained cybersecurity workforce. However, shortages in qualified cybersecurity professionals have been identified, which can hinder the government's ability to ensure an effective workforce. This statement discusses challenges agencies face in ensuring an effective cybersecurity workforce, recent initiatives aimed at improving the federal cyber workforce, and ongoing activities that could assist in recruiting and retaining cybersecurity professionals. In preparing this statement, GAO relied on published work related to federal cybersecurity workforce efforts, and information reported by other federal and non-federal entities focusing on cybersecurity workforce challenges"--Preliminary page.
