AU-06 Audit Record Review, Analysis, and Reporting
Control
- Review and analyze system audit records [Assignement: frequency] for indications of [Assignement: inappropriate or unusual activity] and the potential impact of the inappropriate or unusual activity;
- Report findings to [Assignement: personnel or roles] ; and
- Adjust the level of audit record review, analysis, and reporting within the system when there is a change in risk based on law enforcement information, intelligence information, or other credible sources of information.
Discussion
Audit record review, analysis, and reporting covers information security- and privacy-related logging performed by organizations, including logging that results from the monitoring of account usage, remote access, wireless connectivity, mobile device connection, configuration settings, system component inventory, use of maintenance tools and non-local maintenance, physical access, temperature and humidity, equipment delivery and removal, communications at system interfaces, and use of mobile code or Voice over Internet Protocol (VoIP). Findings can be reported to organizational entities that include the incident response team, help desk, and security or privacy offices. If organizations are prohibited from reviewing and analyzing audit records or unable to conduct such activities, the review or analysis may be carried out by other organizations granted such authority. The frequency, scope, and/or depth of the audit record review, analysis, and reporting may be adjusted to meet organizational needs based on new information received.
Assessment Objective
- system audit records are reviewed and analyzed [Assignement: frequency] for indications of [Assignement: inappropriate or unusual activity] and the potential impact of the inappropriate or unusual activity;
- findings are reported to [Assignement: personnel or roles];
- the level of audit record review, analysis, and reporting within the system is adjusted when there is a change in risk based on law enforcement information, intelligence information, or other credible sources of information.

AU-06(05) Integrated Analysis of Audit Records
|
Control
Integrate analysis of audit records with analysis of [Selection(one-or-more): vulnerability scanning information; performance data; system monitoring information; {{ insert: param, au-06.05_odp.02 }} ] to further enhance the ability to identify inappropriate or unusual activity.
Discussion
Integrated analysis of audit records does not require vulnerability scanning, the generation of performance data, or system monitoring. Rather, integrated analysis requires that the analysis of information generated by scanning, monitoring, or other data collection activities is integrated with the analysis of audit record information. Security Information and Event Management tools can facilitate audit record aggregation or consolidation from multiple system components as well as audit record correlation and analysis. The use of standardized audit record analysis scripts developed by organizations (with localized script adjustments, as necessary) provides more cost-effective approaches for analyzing audit record information collected. The correlation of audit record information with vulnerability scanning information is important in determining the veracity of vulnerability scans of the system and in correlating attack detection events with scanning results. Correlation with performance data can uncover denial-of-service attacks or other types of attacks that result in the unauthorized use of resources. Correlation with system monitoring information can assist in uncovering attacks and in better relating audit information to operational situations.
Assessment Objective
analysis of audit records is integrated with analysis of [Selection(one-or-more): vulnerability scanning information; performance data; system monitoring information; {{ insert: param, au-06.05_odp.02 }} ] to further enhance the ability to identify inappropriate or unusual activity.

AU-06(06) Correlation with Physical Monitoring
|
Control
Correlate information from audit records with information obtained from monitoring physical access to further enhance the ability to identify suspicious, inappropriate, unusual, or malevolent activity.
Discussion
The correlation of physical audit record information and the audit records from systems may assist organizations in identifying suspicious behavior or supporting evidence of such behavior. For example, the correlation of an individual’s identity for logical access to certain systems with the additional physical security information that the individual was present at the facility when the logical access occurred may be useful in investigations.
Assessment Objective
information from audit records is correlated with information obtained from monitoring physical access to further enhance the ability to identify suspicious, inappropriate, unusual, or malevolent activity.
Assessment Method
Examine
Audit and accountability policy
procedures addressing audit review, analysis, and reporting
procedures addressing physical access monitoring

AU-06(07) Permitted Actions
|
Control
Specify the permitted actions for each [Selection(one-or-more): system process; role; user] associated with the review, analysis, and reporting of audit record information.
Discussion
Organizations specify permitted actions for system processes, roles, and users associated with the review, analysis, and reporting of audit records through system account management activities. Specifying permitted actions on audit record information is a way to enforce the principle of least privilege. Permitted actions are enforced by the system and include read, write, execute, append, and delete.
Assessment Objective
the permitted actions for each [Selection(one-or-more): system process; role; user] associated with the review, analysis, and reporting of audit record information are specified.
Assessment Method

AU-06(08) Full Text Analysis of Privileged Commands
|
Control
Perform a full text analysis of logged privileged commands in a physically distinct component or subsystem of the system, or other system that is dedicated to that analysis.
Discussion
Full text analysis of privileged commands requires a distinct environment for the analysis of audit record information related to privileged users without compromising such information on the system where the users have elevated privileges, including the capability to execute privileged commands. Full text analysis refers to analysis that considers the full text of privileged commands (i.e., commands and parameters) as opposed to analysis that considers only the name of the command. Full text analysis includes the use of pattern matching and heuristics.
Assessment Objective
a full text analysis of logged privileged commands in a physically distinct component or subsystem of the system or other system that is dedicated to that analysis is performed.
Assessment Method
Examine
Audit and accountability policy
procedures addressing audit review, analysis, and reporting
system design documentation
system configuration settings and associated documentation

AU-06(09) Correlation with Information from Nontechnical Sources
|
Control
Correlate information from nontechnical sources with audit record information to enhance organization-wide situational awareness.
Discussion
Nontechnical sources include records that document organizational policy violations related to harassment incidents and the improper use of information assets. Such information can lead to a directed analytical effort to detect potential malicious insider activity. Organizations limit access to information that is available from nontechnical sources due to its sensitive nature. Limited access minimizes the potential for inadvertent release of privacy-related information to individuals who do not have a need to know. The correlation of information from nontechnical sources with audit record information generally occurs only when individuals are suspected of being involved in an incident. Organizations obtain legal advice prior to initiating such actions.
Assessment Objective
information from non-technical sources is correlated with audit record information to enhance organization-wide situational awareness.
Assessment Method
Examine
Audit and accountability policy
system security plan
privacy plan
procedures addressing audit review, analysis, and reporting
system design documentation
system configuration settings and associated documentation
documentation providing evidence of correlated information obtained from audit records and organization-defined non-technical sources
