5 FAH-11 H-511 INTRODUCTION

5 FAH-11 H-511.1 Purpose

(CT:IAH-16; 11-08-2018)

a. This subchapter implements the policy in 5 FAM 1060 (Information Assurance Management). It addresses the requirement that Federal agencies collect and report performance metrics and measures for Department programs, including information assurance, to demonstrate compliance with laws and regulations, improve accountability for their programs, and advance efficiencies in delivering programs and services. As required by the Government Performance Results Act (GPRA) and the Clinger-Cohen Act, the Department must ensure that performance measurements are prescribed for Information Technology (IT) used by, or to be acquired for, the Department. In addition, these measurements must indicate how well the IT supports the Departments programs (see 40 U.S.C. 11313(3); see also 31 U.S.C. 1115(a)).

b. These procedures also explain how system owners and managers must work together to ensure that performance metrics are applied for Department information technology (IT) personnel who are assisting in developing, implementing, and managing an IT security program.

c. Current Federal requirements relating to IT security performance measures require a formalized process on how an agency, through the use of metrics, identifies the adequacy of in-place security controls, policies, and procedures.

d. National Institute of Standards and Technology (NIST) Special Publications (SP) SP 800-53A, Revision 4, Guide for Assessing the Security Controls in Federal Information Systems and Organizations: Building Effective Security Assessment Plans, FIPS 200 Minimum Security Requirements for Federal Information and Information Systems, NIST SP 800-53 Revision 4, and NIST SP 800-55, Revision 1 identify management, operational, and technical control topic areas that affect the security posture of an IT system. This subchapter provides a recommended methodology for quantifying the critical elements in NIST SPs 800-53A Revision 4, 800-53, Revision 4, 800-55, Revision 1, and FIPS 200 for monitoring and reporting on implementation and effectiveness of the system security controls.

5 FAH-11 H-511.2 Definitions

(CT:IAH-3; 03-26-2007)

Performance Measures: Evaluation benchmarks that facilitate decision making and accountability through collection, analysis, and reporting of relevant performance data. They provide relevant trends over time and are useful in tracking performance and directing resources to initiate performance improvement actions.

Performance Metrics: A set of standard measures used to identify and evaluate how well specified characteristics or properties of resources, processes, customers, or desired results change over time when compared against a baseline value.

5 FAH-11 H-511.3 Objective

(CT:IAH-3; 03-26-2007)

a. The objective of this subchapter is to provide a comprehensive, uniform approach to developing, implementing, and managing performance measures as they pertain to information assurance at the system level.

b. Understanding the following concepts is vital to improving the effectiveness of measuring performance at the system level:

(1) IT security measures provide a practical approach to assessing information security at the system level through collecting, analyzing, and reporting relevant performance data.

(2) Based on IT security performance goals and objectives, IT security metrics must be quantifiable, measurable, readily collectible, and repeatable. They provide relevant trends over time and are useful in tracking performance, facilitating decision making, and directing resources to initiate performance improvement actions.

(3) System or user-level performance measures are linked to agency measures, which are linked to the Federal mandate for performance measures for information assurance, thereby creating a pyramid of measures that range from tactical to operational to strategic. (See the Departments Information Security Program Plan (ISPP) on the Office of Information Assurance (IRM/IA) Web site; the specific link is shown as Management Plan).

(4) The use of performance measures and the data they reveal support overall management of the IT system over its lifecycle.

(5) Metrics improve accountability to stakeholders, ensure an appropriate level of mission support, determine IT security program effectiveness, and demonstrate program impact to Department management.

5 FAH-11 H-511.4 Scope

(CT:IAH-3; 03-26-2007)

a. This subchapter focuses on how to establish, apply, and maintain information security performance measures at the system level. It also discusses how to develop effective performance measures for capturing the elements in the Information Security Program Plan (ISPP) and to ensure compliance with Department IT performance measures, policies, and security controls (see 5 FAM 130).

b. This subchapter does not include specifics related to agency-level performance measures. However, system-level metrics do support agency-level reporting on progress towards achieving strategic goals (see 5 FAM 671).

5 FAH-11 H-512 Establishing Information security performance measures

5 FAH-11 H-512.1 Performance Measures Essentials

(CT:IAH-3; 03-26-2007)

a. Types of Performance Measures: The type of performance measures used depends on the maturity of the security control implementation in the organization as follows:

(1) Implementation measures: are used when security controls have been defined in procedures and are in the process of being implemented. The metrics are used to demonstrate progress in implementing policies and procedures for individual security controls.

(2) Efficiency measures: in a more advanced security program efficiency measures are used to assess the timeliness and efficiency of security control implementation.

(3) Impact measures: as controls become fully implemented and refined impact measures assess the impact of these controls on the Departments strategic missions and goals, often through quantifying the cost savings produced by the security program or through costs incurred from addressing security events.

b. Characteristics of Performance Measures: IT security performance measures should have the following characteristics:

(1) Quantitative information format (Percentages, averages, and numbers);

(2) Supporting data that is readily available and collectible;

(3) A repeatable process that can be measured repeatedly over time; and

(4) Usefulness to management for tracking performance and directing resources

5 FAH-11 H-512.2 Incorporating Security Controls Into A Security Program Using Performance Measures

(CT:IAH-3; 03-26-2007)

Developing information security performance measures should be a part of a broader process of defining a complete set of performance measures for managing an information security program as noted below:

(1) As a part of its charter for providing guidance on organizing and managing an information security program, NIST has published SP 800-53 that identifies minimum security controls for Federal information systems. These minimum security controls are organized into 17 security control families (see 5 FAH-11 Exhibit H-512.2.)

(2) Information security performance measures provide a means for monitoring and reporting an agencys implementation of the SP 800-53 security controls. The performance measures are also used to assess the effectiveness of the security controls in protecting agency information resources in support of the agencys mission.

5 FAH-11 H-513 HOW TO DEVELOP INFORMATION SECURITY performance measures

(CT:IAH-3; 03-26-2007)

The specific aspect of IT security that performance measures will focus on at a given point in time depends on the maturity of the information security program and its success. The sections listed below explain how to develop performance metrics.

5 FAH-11 H-513.1 Create Metrics

(CT:IAH-3; 03-26-2007)

a. The performance metrics development approach provides two ways of developing metrics, depending on the depth of analysis desired by management:

(1) The control-specific approach selects individual controls as the basis for a metric that best represents the entire control family (see 5 FAH-11 Exhibit H-513.1(1)) as determined by the organizational environment; and

(2) The cross-cutting approach focuses on metrics that gauge security performance based on more than one individual control or control families (see 5 FAH-11 Exhibit H-513.1(2)). This type of metric provides a broader view of information security performance than the control specific approach.

b. Deriving the metric for each method of development involves the following methods:

(1) In the control-specific method, the selected control and derived metric:

(a) Maps directly to an individual control within the respective control family;

(b) Uses the data describing the individual controls implementation to generate required metrics such as plan of action and milestones (POA&M), testing, and project tracking; and

(c) Characterizes the metric as applicable to low, moderate or high system categorization.

(2) In the cross-cutting approach, the metric:

(a) Maps to information security goals and objectives that may encompass performance of several information security controls belonging to several control families; and

(b) Uses the data from two or more control sources describing the security programs performance to generate the required measurement.

5 FAH-11 H-513.2 Apply Metrics Template

(CT:IAH-3; 03-26-2007)

a. Organizations should document their performance measures in a standard format (see paragraph b below) to ensure repeatability of metric development tailoring, collection and reporting processes. A standard format provides detail to guide metrics collection, analysis, and reporting activities.

b. Examples of control metric templates are shown in 5 FAH-11 Exhibit H-513.2(1) (for a control-specific template) and 5 FAH-11 Exhibit H-513.2(2) (for a cross-cutting control template).

5 FAH-11 H-514 MAINTAINING Information security performance measures

5 FAH-11 H-514.1 Collect Data

(CT:IAH-3; 03-26-2007)

a. The Departments automated FISMA reporting tool is IA-supported and provides systems owners and managers with a mechanism for capturing all of the NIST recommended IT security performance measures, including identification and remediation of POA&MS.

b. Systems owners may need to develop other tracking tools to document current performance and archive recorded performance measurement data.

c. Depending on the complexity of the system and the measures selected, a data collection tool may be as simple as an MS Excel spreadsheet or as complex as a custom database with a Web-based front end to display real-time performance measurement information.

5 FAH-11 H-514.2 Meet Reporting Requirements

(CT:IM:03; 03-26-2007)

a. Timing and format for reporting system security performance measures should support the Departments Corrective Action Plan (CAP), quarterly reporting.

b. FISMA data calls issued by IRM/IA will prompt system owners to submit information on the status of their IT security performance measures.
