We need risk management solutions to assess, measure, and mitigate risk in real-time across multi-tier partner and supplier networks to achieve our goal of cost, schedule and performance, as they are only effective in a secure environment.
CISA is tracking a significant cyber incident impacting enterprise networks across federal, state, and local governments, as well as critical infrastructure entities and other private sector organizations. An advanced persistent threat (APT) actor is responsible for compromising the SolarWinds Orion software supply chain, as well as widespread abuse of commonly used authentication mechanisms. This threat actor has the resources, patience, and expertise to gain access to and privileges over highly sensitive information if left unchecked. CISA urges organizations to prioritize measures to identify and address this threat.
Our economy is increasingly global, complex, and interconnected. It is characterized by rapid advances in information technology. IT products and services need to provide sufficient levels of cybersecurity and resilience. The timely availability of international cybersecurity standards and guidance is a dynamic and critical component for the cybersecurity and resilience of all information and communications systems and supporting infrastructures.
IIoT devices are sourced in many different countries and contain many components including hardware, software, and firmware. Each of these devices and components have a supply chain that can be compromised at many points including by the manufacturer, the software libraries, the shippers, the distributors and more.
As awareness of cybersecurity supply chain risks grows among federal agencies, there is a greater need for tools that evaluate the impacts of a supply chain-related cyber event. This can be a difficult activity, especially for those organizations with complex operational environments and supply chains. A publicly available tool to support supply chain risk analysis that specifically takes into account the potential impact of an event does not currently exist. This publication de- scribes how to use the Cyber Supply Chain Risk Management (C-SCRM) Interdependency Tool that has been developed to help federal agencies identify and assess the potential impact of cybersecurity events in their interconnected supply chains.
Many recent data breaches have been linked to supply chain risks. For example, a recent high- profile attack that took place in the second half of 2018, Operation ShadowHammer, compromised an update utility used by a global computer manufacturer.1 The compromised software was served to users through the manufacturer’s official website and is estimated to have impacted up to a million users before it was discovered. This is reminiscent of the attack by the Dragonfly group, which started in 2013 and targeted industrial control systems.2 This group successfully inserted malware into software that was available for download through the manufacturers’ websites, which resulted in companies in critical industries such as energy being impacted by this malware. These incidents are not isolated events. Many recent reports suggest these attacks are increasing in frequency. An Incident Response Threat Report published in April 2019 by Carbon Black highlighted the use of “island hopping” by 50 % of attacks.3 Island hopping is an attack that focuses on impacting not only the victim but its customers and partners, especially if these partners have network interconnections. Symantec’s 2019 Security Threat Report found supply chain attacks increased by 78 % in 2018.4 Perhaps more worrying is that a large number of these attacks appear to be successful and cause significant damage. A November 2018 study, Data Risk in the Third-Party Ecosystem, conducted by the Ponemon Institute found that 59 % of companies surveyed experienced a data breach caused by one of their third parties.5 A July 2018 survey conducted by Crowdstrike found software supply chains even more vulnerable with 66 % of respondents reporting a software supply chain attack, 90 % of whom faced financial impacts as a result of the attack.
Modern weapons systems have depended on microelectronics since the inception of integrated circuits over fifty years ago. Today, most electronics contain programmable components of ever increasing complexity. At the same time, the Department of Defense (DoD) has become a far less influential buyer in a vast, globalized supplier base. Consequently, assuring that defense electronics are free from vulnerabilities is a daunting task.
Because system configurations typically remain unchanged for very long periods of time, compromising microelectronics can create persistent vulnerabilities. Exploitation of vulnerabilities in microelectronics and embedded software can cause mission failure in modern weapons systems. Such exploitations are especially pernicious because they can be difficult to distinguish from electrical or mechanical failures and because effects can run the gamut from system degradation to system failure to system subversion.
Cyber supply chain vulnerabilities may be inserted or discovered throughout the lifecycle of a system. Of particular concern are the weapons the nation depends upon today; almost all were developed, acquired, and fielded without formal protection plans.
Federal agencies are concerned about the risks associated with information and communications technology (ICT) products and services that may contain potentially malicious functionality, are counterfeit, or are vulnerable due to poor manufacturing and development practices within the ICT supply chain. These risks are associated with the federal agencies’ decreased visibility into, understanding of, and control over how the technology that they acquire is developed, integrated and deployed, as well as the processes, procedures, and practices used to assure the integrity, security, resilience, and quality of the products and services. This publication provides guidance to federal agencies on identifying, assessing, and mitigating ICT supply chain risks at all levels of their organizations. The publication integrates ICT supply chain risk management (SCRM) into federal agency risk management activities by applying a multitiered, SCRM- specific approach, including guidance on assessing supply chain risk and applying mitigation activities.
Organizations are concerned about the risks associated with products and services that may contain potentially malicious functionality, are counterfeit, or are vulnerable due to poor manufacturing and development practices within the cyber supply chain. These risks are associated with an enterprise’s decreased visibility into, and understanding of, how the technology that they acquire is developed, integrated, and deployed, as well as the processes, procedures, and practices used to assure the security, resilience, reliability, safety, integrity, and quality of the products and services. This publication provides guidance to organizations on identifying, assessing, and mitigating cyber supply chain risks at all levels of their organizations. The publication integrates cyber supply chain risk management (C-SCRM) into risk management activities by applying a multi-level, C-SCRM-specific approach, including guidance on development of C-SCRM strategy implementation plans, C-SCRM policies, C-SCRM plans, and C-SCRM risk assessments for products and services.
The exploitation of key supply chains by foreign adversaries—especially when executed in concert with cyber intrusions and insider threat activities—represents a complex and growing threat to strategically important U.S. economic sectors and critical infrastructure. The increasing reliance on foreign-owned or controlled hardware, software, or services as well as the proliferation of networking technologies, including those associated with the Internet of Things, creates vulnerabilities in our nation’s supply chains. By exploiting these vulnerabilities, foreign adversaries could compromise the integrity, trustworthiness, and authenticity of products and services that underpin government and American industry, or even subvert and disrupt critical networks and systems, operations, products, and weapons platforms in a time of crisis. We must elevate the role of supply chain security in the acquisition process.
Summary
- Obtain Executive Level Commitment for a Supply Chain Risk Management (SCRM) Program
- Identify Critical Systems, Networks, and Information
- Manage Third Party Risk
If the COVID-19 pandemic and resulting product shortages were not a sufficient wake-up call, the recent software supply chain attacks on U.S. industry and government should serve as a resounding call to action. We must enhance the resilience, diversity, and security of our supply chains. The vitality of our nation depends on it.”
Definition: Supply Chain Risk Management (SCRM) is a discipline that addresses the threats and vulnerabilities of commercially acquired information and communications technologies within and used by government information and weapon systems. Through SCRM, systems engineers can minimize the risk to systems and their components obtained from sources that are not trusted or identifiable as well as those that provide inferior material or parts.
MITRE SE Roles & Expectations: The expansion of the global economy, increased use of outsourcing, and development of open standards are some of the modern day factors that present new challenges to the security of government systems. These factors have resulted in emerging threats and have made protection of the supply chain increasingly difficult [1]. All MITRE systems engineers must understand these emerging threats and why SCRM is necessary to ensure the protection and viability of all government systems.
