Information Warfare Definition "Actions taken to achieve information superiority by affecting adversary information, information-based processes, information system, and computer-based networks while defending one's own information, information-based systems, information systems and computer-based systems."
Information Warfare Definition(s) Information warfare is the offensive and defensive use of information and information systems to deny, exploit, corrupt, or destroy, an adversary's information, information-based processes, information systems, and computer-based networks while protecting one's own. Such actions are designed to achieve advantages over military or business adversaries.(Dr Ivan Goldman)

Levels of Concern (Low, Moderate, High) Level of concern for confidentiality Based on the tolerance for unauthorized disclosure or compromise of information on the system Level of concern for integrity Based on the tolerance for unauthorized modification or destruction of information on the system Level of concern for availability Based on the tolerance for delay in the processing, transmission, or storage of information on the system or the tolerance for the disruption or denial of a service provided by the system
Levels of Concern (Low, Moderate, High) Level of concern for external exposure Based on the definitions in SP (user access methods, backend connections, number of users) Level of concern for internal exposure Based on the definitions in SP (security background assurances/clearances, access approvals, need-to-know) Level of concern for total system exposure Based on the values assigned to both external and internal exposure factors as defined in SP
System Characterization Levels of concern for confidentiality, integrity, availability and system exposure determine: Security controls for the IT system Security certification level
Classes of Security Controls Management Controls Controls that address the security management aspects of the IT system and the management of risk for the system Operational Controls Controls that address the security mechanisms primarily implemented and executed by people (as opposed to systems) Technical Controls Controls that address security mechanisms contained in and executed by the computer system
A Comprehensive Approach Linking Critical Assessment Activities
INFORMATION ASSURANCE (IA) Objectives of the IA Program Employ efficient and cost-effective security features to protect information system resources Adopt a risk-based life cycle management approach Conduct an assessment of threats, identify and apply appropriate safeguards Security Risks = (Threats x Vulnerabilities) - Countermeasures Exposure
Objectives of the IA Program (Continued) Protect the information with regard to: Confidentiality Integrity Availability Authentication Non-repudiation
What is the threat? Internal –Intentional (Disgruntled Employee) –Unintentional (Employee Error) External –Intentional (Terrorists, Hackers) –Unintentional (Natural Disaster)
