As part of an ongoing effort to keep you informed about our latest work, this blog post summarizes some recently published SEI reports, podcasts, and presentations highlighting our work in cyber warfare, emerging technologies and their risks, domain name system blocking to disrupt malware, best practices in network border protection, robotics, technical debt, and insider threat and workplace violence. These publications highlight the latest work of SEI technologists in these areas. This post includes a listing of each publication, author(s), and links where they can be accessed on the SEI website.

Exfiltration of sensitive data on mobile devices is a major concern for the DoD, other organizations, and individuals. Colluding apps in public use have been discovered by security researchers. The Mobile App Collusion attack, which spread across thousands of Android packages, is an example. Colluding apps, or a combination of a malicious app and leaky app, can use intents (messages sent to Android app components) to extract sensitive or private information from an Android phone. This blog post details our work to more precisely detect (i.e., with significantly fewer false positives) malicious exfiltration of sensitive information from an Android phone (even across multiple components), in a practical time and memory bound. In doing this work, we developed a new method for the broader class of problems, not limited to Android, involving information flow analysis for software systems that communicate by message passing: modular analysis with parameterized summaries of flow of sensitive information.
As the defense workforce attracts younger staff members, this digital native generation is having an effect. "To accommodate millennial IT workers, so-called 'digital natives,'" wrote Phil Goldstein in a May 2016 FedTech article, "the service branches of the Department of Defense need to square cybersecurity with the attitudes and behaviors of younger employees, according to senior defense IT officials." Digital natives approach technology differently than digital immigrants, which includes those born before the widespread use of technology. In this blog post, I explore five classic transition models to determine what, if any, considerations we need to account for in today's environment that are different from when they were first published, many of them before the digital natives phenomenon was identified.
The five models are related to technology transition and adoption, and they answer the following questions:
- What kind of technology is it?
- How big is the adoption being contemplated?
- Who will be adopting the new technology?
- What must change agents or technologists do to improve the chance of the technology's success?
- How do we help people get from their current environment to one that leverages the new technology?
Each of these questions is supported by one or more 20th century transition models. Some are still useful as is; others may need to be adapted to the current environment. The observations about digital natives and digital immigrants come from my personal observations over the last 15 years in working with both populations, primarily transitioning practice-based technologies, such as Agile methods.
Insider threat continues to be a problem with approximately 50 percent of organizations experiencing at least one malicious insider incident per year, according to the 2017 U.S. State of Cybercrime Survey. Although the attack methods vary depending on the industry, the primary types of attacks identified by researchers at the CERT Insider Threat Center--theft of intellectual property, sabotage, fraud, and espionage--continue to hold true. In our work with public and private industry, we continue to see that insider threats are influenced by a combination of technical, behavioral, and organizational issues. To address these threats, we have published the fifth edition of the Common Sense Guide to Mitigating Insider Threats, which highlights policies, procedures, and technologies to mitigate insider threats in all areas of the organization. In this blog post, excerpted from the latest edition of the guide, I highlight five best practices that are important first steps for an organization interested in establishing a program to implement to protect and detect insider threats.
