The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), National Security Agency (NSA), and US Department of the Treasury are releasing this Joint Fact Sheet for senior leadership and operations personnel at operational technology (OT) vendors and critical infrastructure facilities. This fact sheet will assist with better management of risk from open source software (OSS) use in OT products and increase resilience using available resources. While several resources and recommendations within this fact sheet are best suited for execution by the vendor or the critical infrastructure owner, collaboration across parties will result in less friction for operator workflows and promote a safer, more reliable system and provision of National Critical Functions. This fact sheet aims to:

Promote the understanding of OSS and its implementation in OT and industrial control systems (ICS) environments. Highlight best practices and considerations for the secure use of OSS in OT.

Critical infrastructure organizations using OSS in OT and ICS face heightened cybersecurity and safety concerns due to the potential far-reaching impacts of incidents and associated life safety implications. Applying generally applicable cyber hygiene practices, such as routinely updating software, can be challenging for organizations using OSS in OT and ICS applications.

All organizations are encouraged to review the Joint Fact Sheet and visit CISA’s new webpage, Securing Open Source Software in Operational Technology for more information.

Cybercriminals often exploit the compassion and generosity of the public by conducting fraudulent schemes in the aftermath of events, such as the recent attacks on Israel that began on October 7. Individuals seeking to donate to relief efforts are targeted in charity scams initiated by threat actors using social engineering tactics through emails, SMS text messaging, phone calls, and direct messages via social media. They often create a sense of urgency and may impersonate reputable organizations. For example, phishing emails may contain display name spoofing to appear as a known or trusted charity and attempt to convince the potential donor to open an attachment or click a link directing them to a cloned or spoofed website impersonating the legitimate charity with the intent to steal sensitive information, user credentials, or relief funds.

Although many legitimate organizations call to solicit donations, potential donors are advised to take the time before donating to research the name of the charity properly, understand who they are and their cause, and where the funds are directed. Also, search the name of the charity to determine if there are any bad reviews, complaints, scams, or fraud associated with the charity. Credit card payments offer more consumer protections and are easier to track than payments of gift cards, wire transfers, cash, or cryptocurrency. Additionally, donations are not recommended through payment apps, such as Venmo, CashApp, or Zelle, as funds through these apps should be sent to known and familiar individuals such as family and friends.

Fraudulent charities or fundraising efforts may also be created to aid terrorist organizations. Traditional fiat currency is typically used for fraudulent fundraising and terrorist financial activity. However, Hamas is one of the first terrorist organizations to use cryptocurrency for fundraising efforts, and authorities recently froze cryptocurrency accounts used by Hamas to elicit donations for their operations.

CISA and the National Security Agency (NSA) published Identity and Access Management: Developer and Vendor Challenges, authored by the Enduring Security Framework (ESF), a CISA- and NSA-led working panel that includes a public-private cross-sector partnership. ESF aims to address risks that threaten critical infrastructure and national security systems.

This publication, which follows ESF’s Identity and Access Management Recommended Best Practices Guide for Administrators, assesses and addresses challenges developers and technology manufacturers face in identity and access management (IAM). The guidance specifically addresses technology gaps that limit the adoption and secure employment of multifactor authentication (MFA) and single sign-on (SSO) technologies within organizations.

Although the publication primarily addresses challenges facing large organizations, it also provides recommendations applicable to smaller organizations. CISA encourages cybersecurity defenders to review this guidance and to speak to their software vendors about implementing its recommendations.

Today, the National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA) released a joint cybersecurity advisory (CSA), NSA and CISA Red and Blue Teams Share Top Ten Cybersecurity Misconfigurations, which provides the most common cybersecurity misconfigurations in large organizations, and details the tactics, techniques, and procedures (TTPs) actors use to exploit these misconfigurations.

The misconfigurations in the CSA illustrate a trend of systemic weaknesses in many large organizations, including those with mature cyber postures, and highlights the importance of software manufacturers embracing secure-by-design principles to reduce the burden on network defenders. Read the Executive Assistant Director at CISA’s blog post on the “Urgency for Software Manufacturers to Incorporate Secure by Design Principles.”

Additionally, NSA and CISA encourage organizations to review the joint CSA for recommended steps and best practices to reduce the risk of malicious actors exploiting the identified misconfigurations. For more information on secure-by-design principles, visit Secure by Design and Security-by-Design and -Default.

Today, CISA, the Federal Bureau of Investigation, the National Security Agency, and the U.S. Department of the Treasury released guidance on improving the security of open source software (OSS) in operational technology (OT) and industrial control systems (ICS). In alignment with CISA’s recently released Open Source Security Roadmap, the guidance provides recommendations to OT/ICS organizations on:

• Supporting OSS development and maintenance,
• Managing and patching vulnerabilities in OT/ICS environments, and
• Using the Cross-Sector Cybersecurity Performance Goals (CPGs) as a common framework for adopting key cybersecurity best practices in relation to OSS.

Alongside the guidance, CISA published the Securing OSS in OT web page, which details the Joint Cyber Defense Collaborative (JCDC) OSS planning initiative, a priority within the JCDC 2023 Planning Agenda. The initiative will support collaboration between the public and private sectors—including the OSS community—to better understand and secure OSS use in OT/ICS, which will strengthen defense against OT/ICS cyber threats.    CISA encourages OT/ICS organizations to review this guidance and implement its recommendations.
