AT-2 · Literacy Training and Awareness

Control statement and discussion

NIST control statement

a. Provide security and privacy literacy training to system users (including managers, senior executives, and contractors): 1. As part of initial training for new users and [Assignment: organization-defined frequency] thereafter; and 2. When required by system changes or following [Assignment: organization-defined events]; b. Employ the following techniques to increase the security and privacy awareness of system users [Assignment: awareness techniques]; c. Update literacy training and awareness content [Assignment: frequency] and following [Assignment: events] ; and d. Incorporate lessons learned from internal or external security incidents or breaches into literacy training and awareness techniques.

Discussion

Organizations provide basic and advanced levels of literacy training to system users, including measures to test the knowledge level of users. Organizations determine the content of literacy training and awareness based on specific organizational requirements, the systems to which personnel have authorized access, and work environments (e.g., telework). The content includes an understanding of the need for security and privacy as well as actions by users to maintain security and personal privacy and to respond to suspected incidents. The content addresses the need for operations security and the handling of personally identifiable information. Awareness techniques include displaying posters, offering supplies inscribed with security and privacy reminders, displaying logon screen messages, generating email advisories or notices from organizational officials, and conducting awareness events. Literacy training after the initial training described in [AT-2a.1](#at-2_smt.a.1) is conducted at a minimum frequency consistent with applicable laws, directives, regulations, and policies. Subsequent literacy training may be satisfied by one or more short ad hoc sessions and include topical information on recent attack schemes, changes to organizational security and privacy policies, revised security and privacy expectations, or a subset of topics from the initial training. Updating literacy training and awareness content on a regular basis helps to ensure that the content remains relevant. Events that may precipitate an update to literacy training and awareness content include, but are not limited to, assessment or audit findings, security incidents or breaches, or changes in applicable laws, executive orders, directives, regulations, policies, standards, and guidelines.

AT-2(2) · Insider Threat

View parent control

Control statement and discussion

NIST control statement

Provide literacy training on recognizing and reporting potential indicators of insider threat.

Discussion

Potential indicators and possible precursors of insider threat can include behaviors such as inordinate, long-term job dissatisfaction; attempts to gain access to information not required for job performance; unexplained access to financial resources; bullying or harassment of fellow employees; workplace violence; and other serious violations of policies, procedures, directives, regulations, rules, or practices. Literacy training includes how to communicate the concerns of employees and management regarding potential indicators of insider threat through channels established by the organization and in accordance with established policies and procedures. Organizations may consider tailoring insider threat awareness topics to the role. For example, training for managers may be focused on changes in the behavior of team members, while training for employees may be focused on more general observations.

View parent control

Control statement and discussion

NIST control statement

Provide literacy training on recognizing and reporting potential and actual instances of social engineering and social mining.

Discussion

Social engineering is an attempt to trick an individual into revealing information or taking an action that can be used to breach, compromise, or otherwise adversely impact a system. Social engineering includes phishing, pretexting, impersonation, baiting, quid pro quo, thread-jacking, social media exploitation, and tailgating. Social mining is an attempt to gather information about the organization that may be used to support future attacks. Literacy training includes information on how to communicate the concerns of employees and management regarding potential and actual instances of social engineering and data mining through organizational channels based on established policies and procedures.

AT-2(4) · Suspicious Communications and Anomalous System Behavior

View parent control

Control statement and discussion

NIST control statement

Provide literacy training on recognizing suspicious communications and anomalous behavior in organizational systems using [Assignment: indicators of malicious code].

Discussion

A well-trained workforce provides another organizational control that can be employed as part of a defense-in-depth strategy to protect against malicious code coming into organizations via email or the web applications. Personnel are trained to look for indications of potentially suspicious email (e.g., receiving an unexpected email, receiving an email containing strange or poor grammar, or receiving an email from an unfamiliar sender that appears to be from a known sponsor or contractor). Personnel are also trained on how to respond to suspicious email or web communications. For this process to work effectively, personnel are trained and made aware of what constitutes suspicious communications. Training personnel on how to recognize anomalous behaviors in systems can provide organizations with early warning for the presence of malicious code. Recognition of anomalous behavior by organizational personnel can supplement malicious code detection and protection tools and systems employed by organizations.

AT-2(5) · Advanced Persistent Threat

View parent control

Control statement and discussion

NIST control statement

Provide literacy training on the advanced persistent threat.

Discussion

An effective way to detect advanced persistent threats (APT) and to preclude successful attacks is to provide specific literacy training for individuals. Threat literacy training includes educating individuals on the various ways that APTs can infiltrate the organization (e.g., through websites, emails, advertisement pop-ups, articles, and social engineering). Effective training includes techniques for recognizing suspicious emails, use of removable systems in non-secure settings, and the potential targeting of individuals at home.

View parent control

Control statement and discussion

NIST control statement

(a) Provide literacy training on the cyber threat environment; and (b) Reflect current cyber threat information in system operations.

Discussion

Since threats continue to change over time, threat literacy training by the organization is dynamic. Moreover, threat literacy training is not performed in isolation from the system operations that support organizational mission and business functions.

AT-6 · Training Feedback

Control statement and discussion

NIST control statement

Provide feedback on organizational training results to the following personnel [Assignment: frequency]: [Assignment: personnel].

Discussion

Training feedback includes awareness training results and role-based training results. Training results, especially failures of personnel in critical roles, can be indicative of a potentially serious problem. Therefore, it is important that senior managers are made aware of such situations so that they can take appropriate response actions. Training feedback supports the evaluation and update of organizational training described in [AT-2b](#at-2_smt.b) and [AT-3b](#at-3_smt.b).

Incident Response · Base control

IR-2 · Incident Response Training

Control statement and discussion

NIST control statement

a. Provide incident response training to system users consistent with assigned roles and responsibilities: 1. Within [Assignment: time period] of assuming an incident response role or responsibility or acquiring system access; 2. When required by system changes; and 3. [Assignment: frequency] thereafter; and b. Review and update incident response training content [Assignment: frequency] and following [Assignment: events].

Discussion

Incident response training is associated with the assigned roles and responsibilities of organizational personnel to ensure that the appropriate content and level of detail are included in such training. For example, users may only need to know who to call or how to recognize an incident; system administrators may require additional training on how to handle incidents; and incident responders may receive more specific training on forensics, data collection techniques, reporting, system recovery, and system restoration. Incident response training includes user training in identifying and reporting suspicious activities from external and internal sources. Incident response training for users may be provided as part of [AT-2](#at-2) or [AT-3](#at-3) . Events that may precipitate an update to incident response training content include, but are not limited to, incident response plan testing or response to an actual incident (lessons learned), assessment or audit findings, or changes in applicable laws, executive orders, directives, regulations, policies, standards, and guidelines.

Planning · Base control

PL-9 · Central Management

Control statement and discussion

NIST control statement

Centrally manage [Assignment: controls and related processes].

Discussion

Central management refers to organization-wide management and implementation of selected controls and processes. This includes planning, implementing, assessing, authorizing, and monitoring the organization-defined, centrally managed controls and processes. As the central management of controls is generally associated with the concept of common (inherited) controls, such management promotes and facilitates standardization of control implementations and management and the judicious use of organizational resources. Centrally managed controls and processes may also meet independence requirements for assessments in support of initial and ongoing authorizations to operate and as part of organizational continuous monitoring. Automated tools (e.g., security information and event management tools or enterprise security monitoring and management tools) can improve the accuracy, consistency, and availability of information associated with centrally managed controls and processes. Automation can also provide data aggregation and data correlation capabilities; alerting mechanisms; and dashboards to support risk-based decision-making within the organization. As part of the control selection processes, organizations determine the controls that may be suitable for central management based on resources and capabilities. It is not always possible to centrally manage every aspect of a control. In such cases, the control can be treated as a hybrid control with the control managed and implemented centrally or at the system level. The controls and control enhancements that are candidates for full or partial central management include but are not limited to: [AC-2(1)](#ac-2.1), [AC-2(2)](#ac-2.2), [AC-2(3)](#ac-2.3), [AC-2(4)](#ac-2.4), [AC-4(all)](#ac-4), [AC-17(1)](#ac-17.1), [AC-17(2)](#ac-17.2), [AC-17(3)](#ac-17.3), [AC-17(9)](#ac-17.9), [AC-18(1)](#ac-18.1), [AC-18(3)](#ac-18.3), [AC-18(4)](#ac-18.4), [AC-18(5)](#ac-18.5), [AC-19(4)](#ac-19.4), [AC-22](#ac-22), [AC-23](#ac-23), [AT-2(1)](#at-2.1), [AT-2(2)](#at-2.2), [AT-3(1)](#at-3.1), [AT-3(2)](#at-3.2), [AT-3(3)](#at-3.3), [AT-4](#at-4), [AU-3](#au-3), [AU-6(1)](#au-6.1), [AU-6(3)](#au-6.3), [AU-6(5)](#au-6.5), [AU-6(6)](#au-6.6), [AU-6(9)](#au-6.9), [AU-7(1)](#au-7.1), [AU-7(2)](#au-7.2), [AU-11](#au-11), [AU-13](#au-13), [AU-16](#au-16), [CA-2(1)](#ca-2.1), [CA-2(2)](#ca-2.2), [CA-2(3)](#ca-2.3), [CA-3(1)](#ca-3.1), [CA-3(2)](#ca-3.2), [CA-3(3)](#ca-3.3), [CA-7(1)](#ca-7.1), [CA-9](#ca-9), [CM-2(2)](#cm-2.2), [CM-3(1)](#cm-3.1), [CM-3(4)](#cm-3.4), [CM-4](#cm-4), [CM-6](#cm-6), [CM-6(1)](#cm-6.1), [CM-7(2)](#cm-7.2), [CM-7(4)](#cm-7.4), [CM-7(5)](#cm-7.5), [CM-8(all)](#cm-8), [CM-9(1)](#cm-9.1), [CM-10](#cm-10), [CM-11](#cm-11), [CP-7(all)](#cp-7), [CP-8(all)](#cp-8), [SC-43](#sc-43), [SI-2](#si-2), [SI-3](#si-3), [SI-4(all)](#si-4), [SI-7](#si-7), [SI-8](#si-8).
