AT&T, Cisco Systems, General Electric, IBM and Intel formed the Industrial Internet Consortium (IIC) about two years ago. The group focuses on industrial uses for the Internet of Things (IoT) and the associated security problems. The consortium now includes over 25 organizations contributing to a new IoT security framework.

The IIC is working toward establishing equipment, such as sensors, valves and motors, capable of communicating with IT systems that can control the machinery and analyze data from the equipment. However, the consortium will not set actual standards or regulations. Instead, it plans to work around existing standards to make products from various vendors work seamlessly together in the real world.

The IoT Security Framework

The IIC recently published its first Industrial Internet Security Framework (IISF) report, which details an in-depth, cross-industry security framework composed of expert vision, experience and best practices. The framework offers a unified approach to assessing cybersecurity posture in an industrial IoT system.

In the document, IIC noted that an Industrial Internet of Things (IIoT) system exhibits five key end-to-end characteristics: security, safety, reliability, resilience and privacy. Other characteristics, such as scalability, usability, maintainability, portability and composability, are also considered important.

Each key system characteristic must be assured in its own way. Still, there may be common techniques available to all of them. According to the document, three elements — confidentiality, integrity and availability — are essential to the security of information and system assets. The report refers to these elements by the acronym CIA.

Immature security may be the biggest factor delaying the adoption of IIoT, Jesus Molina, co-chair of the IIC’s security working group, told CSO Online. Components commonly used in enterprise IT security, such as identity and root of trust, don’t really exist yet in IoT, he explained.

Security Is a Continuum

The document also explained that system security is a continuum, not a Boolean state. It’s important to understand that it’s impossible for every IIoT system to behave securely at all times and within every context.

The IISF is a good first step in addressing a topic that isn’t going away anytime soon. The framework will change, no doubt, as security methods evolve, but the importance of IoT security will only increase.

The compelling need for cloud-native data protection

4 min read - Cloud environments were frequent targets for cyber attackers in 2023. Eighty-two percent of breaches that involved data stored in the cloud were in public, private or multi-cloud environments. Attackers gained the most access to multi-cloud environments, with 39% of breaches spanning multi-cloud environments because of the more complicated security issues. The cost of these cloud breaches totaled $4.75 million, higher than the average cost of $4.45 million for all data breaches.The reason for this high cost is not only the…

What is the Open-Source Software Security Initiative (OS3I)?

3 min read - The Open-Source Software Security Initiative (OS3I) recently released Securing the Open-Source Software Ecosystem report, which details the members’ current priorities and recommended cybersecurity solutions. The accompanying fact sheet also provides the highlights of the report. The OS3I includes both federal departments and agencies working together to deliver policy solutions to secure and defend the ecosystem. The new initiative is part of the overall National Cybersecurity Strategy. After the Log4Shell vulnerability in 2021, the Biden-Harris administration committed to improving the security…

Widespread exploitation of recently disclosed Ivanti vulnerabilities

6 min read - IBM X-Force has assisted several organizations in responding to successful compromises involving the Ivanti appliance vulnerabilities disclosed in January 2024. Analysis of these incidents has identified several Ivanti file modifications that align with current public reporting. Additionally, IBM researchers have observed specific attack techniques involving the theft of authentication token data not readily noted in current public sources. The blog details the results of this research to assist organizations in protecting against these threats. Key Findings: IBM research teams have…
