An industry-accepted way to document what security controls exist in IaaS, PaaS, and SaaS services, providing security control transparency. It provides a set of Yes/No questions a cloud consumer and cloud auditor may wish to ask of a cloud provider to ascertain their compliance to the Cloud Controls Matrix (CCM).
It helps cloud service providers and their customers to gauge the security posture and determine if their cloud services are suitably secure. In addition to improving the clarity and accuracy, it also supports better auditability of the CCM controls.
The Industrial Internet Security Framework (IISF) is a cross-industry-focused security framework comprising expert vision, experience and security best practices. It reflects thousands of hours of knowledge and experiences from security experts, collected, researched and evaluated for the benefit of all IIoT system deployments.
It builds on the ‘Industrial Internet of Things Reference Architecture’ (IIRA), that lays out the most important architecture components, how they fit together and how they influence each other. Each of these components must be made secure, as must the key system characteristics that bind them together into a trustworthy system.
It reviews security assessment for organizations, architectures and technologies. It outlines how to evaluate attacks as part of a risk analysis and highlights the many factors that should be considered, ranging from the endpoints and communications to management systems and the supply chains of the elements comprising the system. Different roles are identified that should be considered in conjunction with the key characteristics, including, owner/operator, system integrator/builder and equipment vendor. Each role offers different risk management perspectives that affect the decisions regarding security and privacy.

While oriented in the first place to consumer devices, ETSI EN 303 645, a standard for cybersecurity in the Internet of Things is relevant for manufacturing considerations. The standard establishes a security baseline for internet-connected consumer products and provides a basis for future IoT certification schemes. Based on the ETSI specification TS 103 645, EN 303 645 went through National Standards Organization comments and voting, engaging even more stakeholders in its development and ultimately strengthening the resulting standard. The EN is a result of collaboration and expertise from industry, academics and government.
ETSI EN 303 645 specifies 13 provisions for the security of Internet-connected consumer devices and their associated services. IoT products in scope include connected children’s toys and baby monitors, connected safety-relevant products such as smoke detectors and door locks, smart cameras, TVs and speakers, wearable health trackers, connected home automation and alarm systems, connected appliances (e.g. washing machines, fridges) and smart home assistants. The EN also includes 5 specific data protection provisions for consumer IoT.
This document provides guidance on how to secure Industrial Control Systems (ICS), including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and other control system configurations such as Programmable Logic Controllers (PLC), while addressing their unique performance, reliability, and safety requirements. The document provides an overview of ICS and typical system topologies, identifies typical threats and vulnerabilities to these systems, and provides recommended security countermeasures to mitigate the associated risks.
ICS cybersecurity programs should always be part of broader ICS safety and reliability programs at both industrial sites and enterprise cybersecurity programs, because cybersecurity is essential to the safe and reliable operation of modern industrial processes. Threats to control systems can come from numerous sources, including hostile governments, terrorist groups, disgruntled employees, malicious intruders, complexities, accidents, and natural disasters as well as malicious or accidental actions by insiders. ICS security objectives typically follow the priority of availability and integrity, followed by confidentiality.
The Framework focuses on using business drivers to guide cybersecurity activities and considering cybersecurity risks as part of the organization’s risk management processes. The Framework consists of three parts: the Framework Core, the Implementation Tiers, and the Framework Profiles. The Framework Core is a set of cybersecurity activities, outcomes, and informative references that are common across sectors and critical infrastructure. Elements of the Core provide detailed guidance for developing individual organizational Profiles. Through use of Profiles, the Framework will help an organization to align and prioritize its cybersecurity activities with its business/mission requirements, risk tolerances, and resources. The Tiers provide a mechanism for organizations to view and understand the characteristics of their approach to managing cybersecurity risk, which will help in prioritizing and achieving cybersecurity objectives.
While this document was developed to improve cybersecurity risk management in critical infrastructure, the Framework can be used by organizations in any sector or community. The Framework enables organizations – regardless of size, degree of cybersecurity risk, or cybersecurity sophistication – to apply the principles and best practices of risk management to improving security and resilience.
The Framework provides a common organizing structure for multiple approaches to cybersecurity by assembling standards, guidelines, and practices that are working effectively today.
The Cybersecurity Framework (CSF) Version 1.1 implementation details developed for the manufacturing environment. The “Manufacturing Profile” of the CSF can be used as a roadmap for reducing cybersecurity risk for manufacturers that is aligned with manufacturing sector goals and industry best practices. This Manufacturing Profile provides a voluntary, risk-based approach for managing cybersecurity activities and reducing cyber risk to manufacturing systems. The Manufacturing Profile is meant to enhance but not replace current cybersecurity standards and industry guidelines that the manufacturer is embracing.
Internet of Things (IoT) devices often lack device cybersecurity capabilities their customers organizations and individuals—can use to help mitigate their cybersecurity risks. Manufacturers can help their customers by improving how securable the IoT devices they make are by providing necessary cybersecurity functionality and by providing customers with the cybersecurity-related information they need. This publication describes recommended activities related to cybersecurity that manufacturers should consider performing before their IoT devices are sold to customers. These foundational cybersecurity activities can help manufacturers lessen the cybersecurity-related efforts needed by customers, which in turn can reduce the prevalence and severity of IoT device compromises and the attacks performed using compromised devices

The CIS Controls™ are a prioritized set of actions that collectively form a defense-in-depth set of best practices that mitigate the most common attacks against systems and networks. The CIS Controls are developed by a community of IT experts who apply their first-hand experience as cyber defenders to create these globally accepted security best practices. The experts who develop the CIS Controls come from a wide range of sectors including, retail, manufacturing, healthcare, education, government, defense, and others. So, while the CIS Controls address the general practices that most organizations should take to secure their systems, some operational environments may present unique requirements not addressed by the CIS Controls.
The guidance on how to apply the security best practices found in CIS Controls. For each top-level CIS Control, there is a brief discussion of how to interpret and apply the CIS Control in such environments, along with any unique considerations or differences from common IT environments. The applicability or not of specific Sub-Controls is addressed and additional steps needed in ICS environments are explained.
The ISA/IEC 62443 standard specifies security capabilities for (industrial) control system components. Developed by the ISA99 committee and adopted by the International Electrotechnical Commission (IEC), provides a framework to address and mitigate security vulnerabilities in industrial automation and control systems (IACSs). it is based upon the input and knowledge of IACS security experts from across the globe to develop consensus standards that are applicable to all industry sectors and critical infrastructure. Central is the application of IACS security zones and conduits (isolation & segmentation), which were introduced in 62443-1-1,
ISA-62443-4-2, Security for Industrial Automation and Control Systems: Technical Security Requirements for IACS Components, provides the cybersecurity technical requirements for components that make up an IACS, specifically the embedded devices, network components, host components, and software applications.
Based on the IACS system security requirements of ISA/IEC 62443‑3-3, System Security Requirements and Security Levels, 4-2 specifies security capabilities that enable a component to mitigate threats for a given security level without the assistance of compensating countermeasures.
ISA/IEC 62443-4-1, Product Security Development Life-Cycle Requirements, specifies process requirements for the secure development of products used in an IACS and defines a secure development life cycle for developing and maintaining secure products. The life cycle includes security requirements definition, secure design, secure implementation (including coding guidelines), verification and validation, defect management, patch management, and product end of life.
ISA/IEC 62443-3-2, Security Risk Assessment, System Partitioning and Security Levels, is based on the understanding that IACS security is a matter of risk management. 3-2 will define a set of engineering measures to guide organizations through the process of assessing the risk of a particular IACS and identifying and applying security countermeasures to reduce that risk to tolerable levels.
By aligning the identified target security level with the required security level capabilities 3‑3, System Security Requirements and Security Levels it takes the earlier 1-1 standard a step further. 2-3, Patch Management in the IACS Environment addresses the installation of patches, also called software updates, software upgrades, firmware upgrades, service packs, hot fixes, basic input/output system updates, and other digital electronic program updates that resolve bug fixes, operability, reliability, and cybersecurity vulnerabilities. It covers many of the problems and industry concerns associated with IACS patch management for asset owners and IACS product suppliers. It also describes the effects poor patch management can have on the reliability and operability of an IACS.
ISO 27000 (or ISO27k) refers to a standard and a series of international standards (27001, 27002, ...) set up by the ISO (International Standards Organization) on information security management series (ISMS). The standard was initiated around 2005 and revised multiple times (2016, 2018) with the support of the different ISO member states representatives, people with an information security background and profession.
The standard describes a norm to which organizations can organize themselves in order to properly manage information and information security. It sets out a series policies, defines the setup of a system to control and manage the policies. Today the standard is being referred to by many compliancy requirement regulations and setups such as the Network and Information Security Directive by the European Commission and the European Member States.
The ISO 27000 series have been divised into multiple sub-standards
27001 :This is the specification for an information security management system (an ISMS) which replaced the old BS7799-2 standard
27002 : This is the 27000 series standard number of what was originally the ISO 17799 standard (which itself was formerly known as BS7799-1)
27003 : guidance for the implementation of an ISMS (IS Management System)
27004 : measurement and metrics
27005 : methodology independent ISO standard
27006 : accreditation of organizations offering ISMS certification.
27007 : ISMS auditing
27032 : CyberSecurity
27033 : Network Security
(* 27013 : Manufacturing)
The objective of the 27001 standard itself is to "provide requirements for establishing, implementing, maintaining and continuously improving an Information Security Management System (ISMS)". Regarding its adoption, this should be a strategic decision. Further, "The design and implementation of an organization's information security management system is influenced by the organization's needs and objectives, security requirements, the organizational processes used and the size and structure of the organization". The original standard was more oriented towards planning and organizing, the later versions more towards measuring and evaluating. 27002 is about controls and control mechanisms.
Organizations can have their ISMS's or their ISO process certified, which can be needed for compliance reasons.
These requirements establish a standard way of expressing the assurance requirements for Targets of Evaluation (TOEs). This part of ISO/IEC 15408 catalogues the set of assurance components, families and classes. This part of ISO/IEC 15408 also defines evaluation criteria for PPs (Protection Profile) and STs (Security Target) and presents evaluation assurance levels that define the predefined ISO/IEC 15408 scale for rating assurance for TOEs, which is called the Evaluation Assurance Levels (EALs). The audience for this part of ISO/IEC 15408 includes consumers, developers, and evaluators of secure IT products. Developers, who respond to actual or perceived consumer security requirements in constructing a TOE, reference this part of ISO/IEC 15408 when interpreting statements of assurance requirements and
determining assurance approaches of TOEs.
A Security Architecture is a conceptual design that addresses various aspects of security in a system and resulting application, set of applications and components that make up the system. It is being used to support the design, development, implementation and operation of these systems, which can include Manufacturing Platforms. For Digital Manufacturing Platforms it addresses necessities and potential risks identified following potential scenario's or within a specific environment. It tries to present a comprehensive perspective of various security concepts on the conceived OT and IT architecture which includes networks, systems and equipment connected to these networks, the communication protocols and operating systems being used, the application development and operational process and recommends the use of security measures using security controls. Having a Security Architecture also helps both the design and integration process, supports identification of incidents and the security monitoring, speeds up discussions with partners for a level play field and best practices and is generally reproducible. Digital Manufacturing Platforms tend to try to bridge operational systems with information technology, such as the use of analytics, data collection and distribution and visualization that can lead to automated actions by these systems on the basis of unattended and unsupervised decisions and control implementations. To avoid physical harm, collateral damage other safety or cybersecurity issues, having a Security Architecture supporting the Digital Manufacturing Platforms should allow developers and companies at least to consider the various aspects and challenges of security in an organized and comprehensible manner. Architectures can follow standards such as IEC62443, ISO27k or NIST800.16, or any alternative scheme, but that needs to complete towards the digital and operational platforms.
