NIST announces the second public comment release of Draft NIST Interagency Report (NISTIR) 7756, CAESARS Framework Extension: An Enterprise Continuous Monitoring Technical Reference Architecture. 1 Government Accountability Office, Report to Congressional Committees, “High-Risk Series: An Update,” USA, February 2013, www.gao.gov/assets/660/652133.pdf2 Performance.gov, “Cross-Agency Priority Goal—Cybersecurity,” www.performance.gov/content/cybersecurity#overview3 Office of Budget Management, “M-14-03. The goal is to facilitate enterprise continuous monitoring by presenting a reference architecture that enables organizations to aggregate collected data from across a diverse set of security tools, analyze that data, perform scoring, enable user queries, and provide overall situational awareness. Members can also earn up to 72 or more FREE CPE credit hours each year toward advancing your expertise and maintaining your certifications. This information provides IT managers with a comprehensive and up-to-date inventory of assets and how they are configured so that they understand what is on their networks and where the networks may be vulnerable. The next layer up is the CSSM (Common Security Services Manager) layer, which consists of published APIs that applications use to access security features such as cryptographic operations and certificate management operations. A data ingest capability was implemented as an asynchronous layer around the database/repository subsystem with a Secure Content Automation Protocol (SCAP)-based7 interface to consume data from the sensor subsystem. [Second Public Draft] This publication presents an enterprise continuous monitoring technical reference architecture that extends the framework provided by the Department of Homeland Security’s CAESARS architecture. Techniques from MDM were applied to address some of the other data integration challenges. The CAESARS report provides a reference architecture, based on security automation standards, that guides organizations in deploying enterprise CM implementations.

It also extends CAESARS to allow for large implementations that need a multi-tier architecture. Figure 5 depicts these key datasets and the order of magnitude in the number of records that were collected. The CAESARS reference architecture represents the essential functional components of an ISCM and risk-scoring system, as depicted in figure 1. A Caesar cipher is one of the simplest and most well-known encryption techniques. ITL Bulletins The US Government Accountability Office (GAO) cites that from 2006 to 2012, the number of cyberincidents reported by federal agencies to the US Computer Emergency Readiness Team (US-CERT) grew from 5,503 to 48,562, an increase of 782 percent.1. The goal is to facilitate enterprise continuous monitoring by presenting a reference architecture that enables organizations to aggregate collected data from across a diverse set of security tools, analyze that data, perform scoring, enable user queries, and provide overall situational awareness. Scientific Integrity Summary | Maintains a current picture of an organization’s security posture. ISACA® membership offers you FREE or discounted access to new knowledge, tools and training. For example, the algorithms were implemented to be robust enough to account for missing data, but then were assigned default values that would penalize the sites for missing data and this was used to drive behavior to ensure that the organization would publish their sensor data correctly in the future. “Information security continuous monitoring is defined as maintaining ongoing awareness of information security, vulnerabilities and threats to support organizational risk management decisions.”4 This means continuously collecting information to provide a comprehensive understanding of everything that is deployed on an enterprise’s networks and using this information to assess compliance against security policies and exposure to threats and vulnerabilities. 01/06/12: NISTIR 7756 (Draft), Security and Privacy For example, the initial phase of the DHS’s CDM program is focused on hardware and software asset management, configuration settings, known vulnerabilities and malware. DMTF’s Platform Management Components Intercommunication (PMCI) Security Task Force has published a Work In Progress architecture presentation for two new upcoming specifications.. Implementing an Information Security Continuous Monitoring Solution—A Case Study, www.performance.gov/content/cybersecurity#overview, www.whitehouse.gov/sites/default/files/omb/memoranda/2014/m-14-03.pdf, http://csrc.nist.gov/publications/nistpubs/800-137/SP800-137-Final.pdf, www.federalcybersecurity.org/CourseFiles/ContinuousMonitoring/fns-caesars.pdf, www.state.gov/documents/organization/156865.pdf, http://energy.gov/oe/services/cybersecurity/cybersecurity-capability-maturity-model-c2m2-program/cybersecurity. IBM Security Guardium® Data Encryption is a suite of products that offers capabilities for protecting and controlling access to databases, files, containers, and applications. The database/repository subsystem needs a robust architecture that can support multiple interaction models—a lot of writes to ingest data from the sensor subsystem, batch and real-time processing to support the analytics, and ad hoc queries from users. In November 2013, the US Office of Management and Budget (OMB) issued memorandum M-14-03 requiring all federal departments and agencies to establish an information security continuous monitoring (ISCM) program.3 The US Department of Homeland Security (DHS) has been tasked to work with all of the departments and agencies to help them implement continuous monitoring through the Continuous Diagnostics and Mitigation (CDM) program.

Expand the CAESARS Reference Architecture to include reference to tools for extracting, parsing and/or otherwise manipulating subsystem sensor data in preparation for analysis. This enables the comparative analyses required to identify the worst areas to fix first and enables administrators to drill down into specific assets that have to be remediated. The SABSA methodology has six layers (five horizontals and one vertical). A great deal of data transformation at the point of data ingestion could create a bottleneck, so the schema for this first stage was designed to closely resemble the data models used by Asset Reporting Format (ARF )8 and Asset Summary Reporting (ASR).9 Once the data were ingested, a separate set of jobs would perform the consolidation, correlation and fusion to create the complete, up-to-date profile of the asset. The analytics and risk scoring have to be applied at multiple levels, from the individual asset or device level, to the network enclave level, to the department level and, finally, up to the enterprise level.

This system started with a single database architecture, but evolved into a three-stage data architecture to support the diverse and sometimes conflicting requirements described herein. Drafts for Public Comment Of course some key assets as passwords or personal data should never be accessible. Author: Marc Lankhorst, Chief Technology Evangelist & Managing Consultant at BiZZdesign Marc Lankhorst, Chief Technology Evangelist & Managing Consultant at BiZZdesign, is widely acknowledged as the “father of ArchiMate”, the de facto standard for modeling enterprise architecture.Marc has more than 20 years of experience as an enterprise architect, trainer, coach, and project manager. SCAP standards such as ARF, ASR and the Extensible Configuration Checklist Description Format (XCCDF) are rather verbose XML formats and can be very central processing unit (CPU)- and memory-intensive to process. These problems are not unique to continuous monitoring and there are many available solutions to address them (e.g., the use of fast-streaming XML parsers to quickly write the ARF, ASR and XCCDF data to the database and have separate jobs to do the consolidation and correlation so that no bottleneck is created at ingestion). None available, Related NIST Publications: audit & accountability; continuous monitoring; incident response; maintenance; security automation; threats, Laws and Regulations A continuous monitoring system is essentially a data analytics application, so at a high level, the architecture for a continuous monitoring system, depicted in figure 1, resembles that of most typical data analytics/business intelligence (BI) applications. Contact Us, Privacy Statement | NIST Information Quality Standards, Business USA | The risk-scoring algorithms can get quite complex when taking into consideration the different types of defects/findings, the severities of the findings, the threats and the impact on the affected assets. Healthcare.gov | Key data architecture challenges presented by these requirements are described in figure 3. DHS has defined a technical reference architecture for continuous monitoring called the Continuous Asset Evaluation, Situational Awareness, and Risk Scoring (CAESARS) reference architecture5 based on the work of three leading US federal agencies that have successfully implemented continuous monitoring solutions: the US Department of State (DOS), the US Internal Revenue Service (IRS) and the US Department of Justice (DOJ).
