The Unauthorized Disclosure And Modification Of Data Information Technology Essay
The purpose of this risk assessment is to evaluate the adequacy of the System Name and Acronym security. This risk assessment provides a structured qualitative assessment of the operational environment. It addresses sensitivity, threats, vulnerabilities, risks and safeguards. The assessment recommends cost-effective safeguards to mitigate threats and associated exploitable vulnerabilities.
The scope of this risk assessment assessed the system’s use of resources and controls (implemented or planned) to eliminate and/or manage vulnerabilities exploitable by threats internal and external to the Centers for Disease Control and Prevention (CDC). If exploited, these vulnerabilities could result in:
Unauthorized disclosure of data
Unauthorized modification to the system, its data, or both
Denial of service, access to data, or both to authorized users
This Risk Assessment Report evaluates the confidentiality (protection from unauthorized disclosure of system and data information), integrity (protection from improper modification of information), and availability (loss of system access) of the system. Recommended security safeguards will allow management to make decisions about security-related initiatives.
The <System Name> mission is to …
RISK ASSESSMENT APPROACH
This risk assessment methodology and approach was conducted using the guidelines in NIST SP 800-30, Risk Management Guide for Information Technology Systems. The assessment is broad in scope and evaluates security vulnerabilities affecting confidentiality, integrity, and availability. The assessment recommends appropriate security safeguards, permitting management to make knowledge-based decisions about security-related initiatives. The methodology addresses the following types of controls:
Management Controls: Management of the information technology (IT) security system and the management and acceptance of risk
Operational Controls: Security methods focusing on mechanisms implemented and executed primarily by people (as opposed to systems), including all aspects of physical security, media safeguards, and inventory controls
Technical Controls: Hardware and software controls providing automated protection to the system or applications (Technical controls operate within the technical system and applications.)
Risk Assessment Process
This section details the risk assessment process performed during this effort. The process is divided into pre-assessment, assessment, and post-assessment phases.
Phase I – Pre-Assessment
Step 1: Define the Nature of the Risk Assessment
This initial risk assessment provides an independent review to help CDC determine the appropriate level of security required for the system to support the development of a System Security Plan for <System Name>. The review also provides the information required for the Chief Information Security Officer (CISO) and Designated Approving Authority (DAA (also known as the Authorizing Official)) to make an informed decision about authorizing the system to operate. The risk assessment is based on interviews, documentation and, as necessary, some automated technical review.
Step 2: Data Collection
The data collection phase included identifying and interviewing key personnel within the organization and conducting document reviews. Interviews focused on the operating environment. Document reviews provided the risk assessment team with the basis on which to evaluate compliance with policy and procedure.
Step 3: Templates
The following templates were used by the risk assessment team and are included in the appendices:
NIST SP 800-53, Revision 2, Security Baseline Worksheet: Completed by the analysts using information extracted from questionnaires and interviews.
Risk Calculation Worksheet: Converts the raw vulnerabilities into risks based on the following methodology:
Pairing with threat vectors
Assessing the probability of occurrence and possible impact
Determining e-authentication EAAL threat vectors
Risk Mitigation Worksheet: Lists the risks and the associated recommended controls to mitigate these risks for the Business Steward to review. The Business Steward is responsible for formally accepting each recommended control or rejecting it and providing an alternative. For each rejected recommendation, the CDC Business Steward must note that the risk is to be accepted as residual risk. The Certification Agent (CA) (for the CDC this is the CDC CISO) will, at the same time or shortly thereafter, evaluate the Business Steward’s selections and agree to each (e.g., accepting the risks and chosen recommended controls) or will negotiate an alternative mitigation, while reserving the right to override the Business Steward’s decision and incorporate the proposed recommended control into the Plan of Action and Milestones (POA&M).
Phase II – Assessment
Step 1: Document Review
The assessment phase began with the review of documents provided by the members of the CDC <System Name> system team. Detailed interviews with members of the CDC <System Name> system team allowed completion of the system questionnaire and identification of specific threats inadequately identified in the Enterprise Threat Statement.
Step 2: System Characterization
In this step, the analyst defined the boundaries of the IT system, along with the resources that constitute the system, its connectivity, and any other elements necessary to describe the system. Dependencies were clarified. Sensitivity of the system and data was discussed in the final section of the characterization.
Step 3: Threat Identification
The risk assessment team used the CDC Enterprise Threat Statement and the NIST SP 800-30 as a basis for threat identification. Through the interview process, it also identified “most likely” system and location-specific threats.
Step 4: Vulnerability Identification
In this step, the risk assessment team developed a list of system vulnerabilities (flaws or weaknesses) that could be exploited by the potential threat vectors. The NIST SP 800-53, Revision 2, Security Baseline Worksheet (Appendix B of the Risk Assessment Report) documents vulnerabilities extracted from interviews and documents, and lists them by category.
Step 5: Risk Determination (Calculation/Valuation)
In this step, the risk assessment team determined the degree of risk to the system. In some cases, a series of vulnerabilities combined to create the risk. In other cases, a single vulnerability created the risk. The determination of risk for a particular threat source was expressed as a function of the following:
Likelihood Determination: The following governing factors were considered when calculating the likelihood of the probability that a potential vulnerability might be exploited in the context of the associated threat environment:
Threat source motivation and capability
Nature of the vulnerability
Existence and effectiveness of current controls
The following table defines the likelihood determinations.
Table (?). Likelihood Definition
The threat source is highly motivated and sufficiently capable, and controls to prevent the vulnerability from being exercised are ineffective.
The threat source is motivated and capable, but controls are in place that may impede successful exercise of the vulnerability.
The threat source lacks motivation or capability, or controls are in place to prevent, or at least significantly impede, the vulnerability from being exercised.
Impact Analysis: The next major step in measuring level of risk was to determine the adverse impact resulting from successful exploitation of a vulnerability. The adverse impact of a security event can be described in terms of loss or degradation of any, or a combination of any, of the following three security goals:
Loss of Confidentiality – Impact of unauthorized disclosure of sensitive information (e.g., Privacy Act).
Loss of Integrity – Impact if system or data integrity is lost by unauthorized changes to the data or system.
Loss of Availability – Impact to system functionality and operational effectiveness.
Table (?). Impact Definition
Magnitude of Impact
Exercise of the vulnerability (1) may result in the highly costly loss of major tangible assets or resources; (2) may significantly violate, harm, or impede an organizations mission, reputation, or interest; or (3) may result in human death or serious injury.
Exercise of the vulnerability (1) may result in the costly loss of tangible assets or resources; (2) may violate, harm or impeded an organization’s mission, reputation, or interest; or (3) may result in human injury.
Exercise of the vulnerability (1) may result in the loss of some tangible assets or resources; (2) may noticeably affect an organization’s mission, reputation, or interest.
Risk Determination: The following were used to assess the level of risk to the IT system:
The likelihood of a given threat source’s attempting to exercise a given vulnerability.
The magnitude of the impact should a threat-source successfully exercise the vulnerability.
The adequacy of planned or existing security controls for reducing or eliminating risk.
The following table provides a definition for the risk levels. These levels represent the degree or level of risk to which an IT system, facility, or procedure might be exposed if a given vulnerability were exercised.
Table (?). Risk Level Definition
Magnitude of Impact
Risk Level Definition
There is a strong need for corrective measures. An existing system may continue to operate, but a corrective action plan must be put in place as soon as possible.
Corrective actions are needed and a plan must be developed to incorporate these actions within a reasonable period of time.
The system’s Authorizing Official must determine whether corrective actions are still required or decide to accept the risk.
Step 6: Risk Mitigation Recommendations
During this step of the process, controls that could mitigate or eliminate the identified risks, as appropriate to the organization’s operations, were provided. The goal of the recommended controls is to reduce the level of risk to the IT system and its data to an acceptable level. The risk assessment team considered the following factors when recommending controls and alternative solutions to minimize or eliminate identified risks:
Sensitivity of the data and the system
Effectiveness of recommended options
Legislation and regulations
Safety and reliability
The recommendations were the results of the risk assessment process, and provide a basis by which the CISO and Authorizing Official can evaluate and prioritize controls. The Business Steward will work with the CISO to negotiate the implementation of the recommended controls. At this point, the System Steward can negotiate with the CISO to accept the recommendations for risk mitigation, provide alternative suggestions, or reject the recommendations and accept the risk as residual risk. Their joint decision will form the basis of the POA&M.
Phase III – Post Assessment
Step 1: Risk Mitigation
The completed POA&M is the product from the preparation of the Risk Mitigation Worksheet and specific remedial recommendations to mitigate risk. Because the elimination of all risk is usually impractical, senior management and business stewards should assess control recommendations, determine the acceptable level of residual risk, and implement those mitigations with the most appropriate, effective, and highest payback.
Step 2: Ongoing Monitoring
The agreed-upon milestones to mitigate the risks are reportable to the Office of Management and Budget (OMB) and the POA&M is the reporting vehicle. The POA&M will be used by the CISO to monitor the successful completion of the milestones.
System Stewards and Designated Approving Authority
The <System Name> system became operational in January 2002 after being renamed from Acquisition Management Automation System (AMAS). It is continuously updated and is presently maintained by System Stewards (Table ?) in both the Management Information Systems Branch (MISB) and Procurement Grants Office (PGO).
The following is contact information for <System Name> System Stewards and DAA.
Table ?. System Stewards and Designated Approving Authority (DAA)
The <System Name> system maintains information on the CDC’s contracts, bids for services, procurement, and bid award data. Bidding information from contractors is kept private until a contract is awarded.
The <System Name> system is a client/server package that enables processing of both large contracts and simplified acquisition procurements (SAP). This Government Off-the-Shelf (GOTS) software package has replaced the Small Purchases Processing System (SPPS) and the Automated Receiving System (ARS).
The system was originally developed for the Department of Defense, but was customized for CDC by the BayTech Consulting Group of Annapolis, MD, between 1998 and 2003. Currently, CDC has a contract with DB Consulting Group on site at PGO for further development and maintenance of the system as its full functionality is realized. The original system name, AMAS, was changed to <System Name> to reflect functionality added for CDC.
<System Name> is a stand alone system that has no current real-time interfaces. <System Name> has the following batch interfaces:
[Example: The <System Name> system environment is a client/server environment consisting of a Microsoft (MS) Structured Query Language (SQL) database built with PowerBuilder programming code. <System Name> contains production data files, application code, and executables. The production data files, consisting of stored procedures and tables, reside on a Clarion storage area network (SAN) attached to a Dell server running on Windows 2000 and MS SQL 2000 operating systems. The application code resides on a different Dell server running on Windows 2000. Both servers are housed in the Building 16 Data Center at the CDC Clifton Road campus in Atlanta, GA. The <System Name> executables reside on a fileserver running Windows 2000 or a local workstation depending upon the location and job functionality.
Users are physically located in multiple locations (multiple campuses in Atlanta, Cincinnati, Pittsburgh, Morgantown, Ft. Collins, Denver, Anchorage, Research Triangle Park, and San Juan). Their desktop computers are physically connected to a wide area network (WAN). Some users connect via secured dial-up/DSL connection using a Citrix server. Normally, a user connects to an application server in their city that hosts the <System Name> application, and to the shared database server located in Atlanta. All CIOs throughout CDC/ATSDR are users of <System Name>].

List specific dependencies
Beyond these dependencies, a set of common dependencies was defined to enable boundary definition. A dependency is a telecommunication or information technology interconnection or resource on which the system under review relies for processing, transport, or storage. The relationship between the system in question and the dependencies can directly affect the confidentiality, integrity, or availability of the system or its data. Whenever a system has a dependency, the system inherits the intrinsic risks of the dependent asset. The following CDC information technology resources can be considered dependencies:
CDC Enterprise Policies
CDC Enterprise Mid-Tier Data Center
CDC Network Infrastructures:
Center or Information Technology Services Office (ITSO) Local Area Networks
Atlanta Metropolitan Area Network
CDC Wide Area Network
CDC Enterprise Security Services:
CDC Border Firewall
CDC Border Router Access Control Lists
Network-Based Intrusion Detection Systems
E-Mail Gateway Virus Scanning and Attachment Removal
RSA SecurID Authentication System
Technical Vulnerability Scanning Service (Most Commonly Used for Hosts Deployed to the DMZ)
CDC Computer Room Staff, Physical, and Environmental Controls
CDC Exchange Services:
Enterprise E-Mail Gateway Infrastructure with Gateway Virus Protection
ITSO or Center Managed Local E-Mail Stores with Server Virus Protection
Remote Access Web Mail Services with RSA SecurID Authentication

The following systems depend on <System Name> to perform or fulfill their function:
This section provides a description of the types of information handled by <System Name> and an analysis of the sensitivity of the information. The sensitivity of the information stored within, processed by or transmitted by <System Name> provides a basis for the value of the system and is one of the major factors in risk management.
FIPS 199 establishes three potential impact levels (Low, Moderate, High) for each of the security objectives (confidentiality, integrity, and availability). The impact levels focus on the potential impact and magnitude of harm that the loss of confidentiality, integrity, or availability (C/I/A) would have on CDC’s operations, assets, or individuals. FIPS 199 recognizes that an information system may contain more than one type of information (e.g., privacy information, medical information, financial information), each of which is subject to security categorization. Section 3.8.1 discusses the security categorization/ information type(s) for <System Name>.
Security Categorization/Information Type(s)
The security category of an information system that processes, stores, or transmits multiple types of information should be at least the highest impact level that has been determined for each type of information for each security objective of C/I/A. The following table depicts the security category/information type for <System Name> as identified in the <System Name> Risk Assessment Report.

The following table provides the definitions for C/I/A ratings for <System Name>.
Table (?). Confidentiality, Integrity, and Availability Defined
Preserving authorized restrictions on information access and disclosure, including means for protection personal privacy and proprietary information
[44 USC, SEC. 3542]
The unauthorized disclosure of information could be expected to have a limited adverse effect on organizational operations, organizational assets, or individuals.
The unauthorized disclosure of information could be expected to have a serious adverse effect on organizational operations, organizational assets, or individuals.
The unauthorized disclosure of information could be expected to have a severe or catastrophic adverse effect on organizational operations, organizational assets, or individuals.
Guarding against improper information modification or destruction, and includes ensuring information non-repudiation and authenticity.
[44 USC, SEC. 3542]
The modification or destruction of information could be expected to have a limited adverse effect on organizational operations, organizational assets, or individuals.
The modification or destruction of information could be expected to have a serious adverse effect on organizational operations, organizational assets, or individuals.
The modification or destruction of information could be expected to have a severe or catastrophic adverse effect on organizational operations, organizational assets, or individuals.
Ensuring timely and reliable access to and use of information.
[44 USC, SEC. 3542]
The disruption of access to or use of information or an information system could be expected to have a limited adverse effect on organizational operations, organizational assets, or individuals.
The disruption of access to or use of information or an information system could be expected to have a serious adverse effect on organizational operations, organizational assets, or individuals.
The disruption of access to or use of information or an information system could be expected to have a severe or catastrophic adverse effect on organizational operations, organizational assets, or individuals.
The sensitivity designation of information processed by <System Name> is (High, Moderate, Low). This (High, Moderate, Low) designation is based upon the C/I/A designation of the information type for <System Name>.
Both information and information systems have distinct life cycles. It is important that the degree of sensitivity of information be assessed by considering the requirements for the C/I/A of the information: the need for system data to be kept confidential; the need for the data processed by the system to be accurate, and the need for the system to be available. Confidentiality focuses on the impact of disclosure of system data to unauthorized personnel. Integrity addresses the impact that could be expected should system data be modified or destroyed. Availability relates to the impact to the organization should use of the system be denied.
Protection Requirement Findings 
Confidentiality: [Example: <System Name> contains sensitive information that could identify a survey participant. This data requires protection from unauthorized disclosure. If information contained in <System Name> were released to the public it could result in a loss of public confidence in the survey, affect participation, and cause a great deal of embarrassment to the CDC]. Therefore, the unauthorized disclosure of <System Name> information could be expected to have a (limited, serious, or severe) adverse effect on organizational operations, organizational assets, or individuals and the information and protection measures are rated as (Low, Moderate, High).
Integrity: [Example: <System Name> collects and processes health and nutritional information annually from a representative sample of the U. S. population. Because public health trends and policies depend on the accuracy of the data collected, unauthorized and unanticipated modification would seriously reduce the accuracy of the survey results]. Therefore, the unauthorized modification of <System Name> information could be expected to have a (limited, serious, or severe) adverse effect on organizational operations, organizational assets, or individuals and the information and protection measures are rated as (Low, Moderate, High).
Availability: [Example: If <System Name> were unavailable for even a short period of time, it would have an immediate impact and would affect the efficiency with which <System Name> typically operates]. Therefore, the unavailability of <System Name> information could be expected to have a (limited, serious, or severe) adverse effect on organizational operations, organizational assets, or individuals and the information and protection measures are rated as (Low, Moderate, High).
NIST SP 800-30 describes the identification of the threat, the threat source and threat action for use in the assessment process. The following is a definition for each:
Threat – The potential for a particular threat-source to successfully exercise a particular vulnerability. (Vulnerability is a weakness that can be accidentally triggered or intentionally exploited)
Threat Source – Any circumstance or event with the potential to cause harm to an IT system. The common threat sources can be natural, human or environmental.
Threat Action – The method by which an attack might be carried out (e.g., hacking, system intrusion).
Enterprise Threat Vector
Acts of Nature. Earthquakes, rain, wind, ice, etc., that threaten facilities, systems, personnel, utilities, and physical operations.
Hazardous Conditions. Fire, chemical and nuclear spills, biological events, structural instability, etc., that threaten facilities, systems, personnel, and operations. May be the result of natural events, environmental control failures, human errors, and/or violent acts.
Dependency Failures. Failure of a system or service outside the direct control of the system owners that harms the system and/or affects its ability to perform. Also includes system worker termination and reassignment actions. Examples include utility failures, downstream processing failures, system administrator or subject matter expert job termination, or the failure of a service or control owned by another part of the organization.
System and Environmental Failures. Failure of a computer, device, application, communication service, or environmental or protective control that disrupts, harms, or exposes the system to harm. Examples include system hardware failures, environmental control failures, and software or data corruption.
Violent Acts of Man. Physical attack or threat of attack on a national, regional, or local level that directly impacts the system and/or its personnel or that results in indirect harm or dependency failure.
Errors and Omissions. Accidental or ill-advised actions taken by personnel (typically insiders) that result in unintended physical damage, system disruption, and/or exposure.
Insider Attack. Actions taken by insiders to harm the organization and its personnel, systems, and/or data and/or that of other parties. Examples include system compromise, escalation of privileges, electronic eavesdropping, password guessing, denial of service, and social engineering.
Insider Abuse and Unauthorized Acts. Unauthorized, illegal, or inappropriate insider acts that cause disruption and/or harm. Although these actions are intentional, computing resources are typically the vehicle used to commit the act rather than its target. Examples include sharing or distribution of copyrighted material, invasion of privacy, exploration of unauthorized computer systems, use of computing resources to harass others, and disregard for security controls.
External Attack. Actions taken by outside parties seeking to harm the organization, its personnel, systems, and/or data and/or that of other parties. Examples include system compromise, data and account harvesting, defacement, computer crime, password guessing, denial of service, and social engineering.
Autonomous Systems and Malicious Code. Automated actions taken by program code or systems that result in harm to the organization, its systems, and/or its data and/or that of other parties. Examples include viruses, worms, and artificial intelligence control or response systems.
Physical Intrusion and/or Theft. Facility compromise and/or theft of physical resources (data, hardcopy output, laptops, systems, access tokens, passwords, etc.) that could directly or indirectly result in harm to the organization or the system.
Legal and Administrative Actions. Actions taken by law enforcement, regulatory, administrative, and/or other parties as a result of illegal acts and failures in due diligence and/or due care, or in seeking recompense for damages incurred by others. Examples include regulatory penalties, criminal and civil proceeding.
NIST SP 800-63 describes the categories of harm and impact as:
Inconvenience, distress, or damage to standing or reputation
Financial loss or agency liability
Harm to agency programs or public interests
Unauthorized release of sensitive information
Civil or criminal violations
Required assurance levels for electronic transactions are determined by assessing the potential impact of each of the above categories using the potential impact values described in FIPS 199, “Standards for Security Categorization of Federal Information and Information Systems.” The three potential impact values are:
The next section defines the potential impacts for each category. Note: If authentication errors cause no measurable consequences for a category, there is “no” impact.
Determining Potential Impact of Authentication Errors
Potential Impact of Inconvenience, Distress, or Damage to Standing or Reputation:
Low—at worst, limited, short-term inconvenience, distress or embarrassment to any party.
Moderate—at worst, serious short term or limited long-term inconvenience, distress or damage to the standing or reputation of any party.
High—severe or serious long-term inconvenience, distress or damage to the standing or reputation of any party (ordinarily reserved for situations with particularly severe effects or which affect many individuals).
Potential Impact of Financial Loss
Low—at worst, an insignificant or inconsequential unrecoverable financial loss to any party, or at worst, an insignificant or inconsequential agency liability.
Moderate—at worst, a serious unrecoverable financial loss to any party, or a serious agency liability.
High—severe or catastrophic unrecoverable financial loss to any party; or severe or catastrophic agency liability.
Potential Impact of Harm to Agency Programs or Public Interests
Low—at worst, a limited adverse effect on organizational operations or assets, or public interests. Examples of limited adverse effects are: (i) mission capability degradation to the extent and duration that the organization is able to perform its primary functions with noticeably reduced effectiveness, or (ii) minor damage to organizational assets or public interests.
Moderate—at worst, a serious adverse effect on organizational operations or assets, or public interests. Examples of serious adverse effects are: (i) significant mission capability degradation to the extent and duration that the organization is able to perform its primary functions with significantly reduced effectiveness; or (ii) significant damage to organizational assets or public interests.

Examples of severe or catastrophic effects are: (i) severe mission capability degradation or loss of to the extent and duration that the organization is unable to perform one or more of its primary functions; or (ii) major damage to organizational assets or public interests.
Potential impact of Unauthorized Release of Sensitive Information
Low—at worst, a limited release of personal, U.S. government sensitive or commercially sensitive information to unauthorized parties resulting in a loss of confidentiality with a low impact as defined in FIPS PUB 199.
Moderate—at worst, a release of personal, U.S. government sensitive or commercially sensitive information to unauthorized parties resulting in loss of confidentiality with a moderate impact as defined in FIPS PUB 199.
High – a release of personal, U.S. government sensitive or commercially sensitive information to unauthorized parties resulting in loss of confidentiality with a high impact as defined in FIPS PUB 199.
Potential impact to Personal Safety
Low—at worst, minor injury not requiring medical treatment.
Moderate—at worst, moderate risk of minor injury or limited risk of injury requiring medical treatment.
High—a risk of serious injury or death.
Potential Impact of Civil or Criminal Violations
Low—at worst, a risk of civil or criminal violations of a nature that would not ordinarily be subject to enforcement efforts.
Moderate—at worst, a risk of civil or criminal violations that may be subject to enforcement efforts.
High—a risk of civil or criminal violations that are of special importance to enforcement programs.
