Summary

This Joint Cybersecurity Advisory was coauthored by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Australian Cyber Security Centre (ACSC), the United Kingdom’s National Cyber Security Centre (NCSC), and the U.S. Federal Bureau of Investigation (FBI).

This advisory provides details on the top 30 vulnerabilities—primarily Common Vulnerabilities and Exposures (CVEs)—routinely exploited by malicious cyber actors in 2020 and those being widely exploited thus far in 2021.

Cyber actors continue to exploit publicly known—and often dated—software vulnerabilities against broad target sets, including public and private sector organizations worldwide. However, entities worldwide can mitigate the vulnerabilities listed in this report by applying the available patches to their systems and implementing a centralized patch management system.

Balena is a complete set of tools for building, deploying, and managing fleets of connected Linux devices. We provide infrastructure for fleet owners so they can focus on developing their applications and growing their fleets with as little friction as possible.

Our tools are designed to work well together as a platform, but you can also pick and choose the components you need for your project, and adapt them to your particular use case. We know that no two IoT projects are the same and there is no one-size-fits-all solution.

If you’re eager to learn more about the inner workings of balena, you’re in luck! We’re eager to share. This guide covers the components and workflows involved in a typical balena deployment.
