As part of an ongoing effort to keep you informed about our latest work, I would like to let you know about some recently published SEI technical reports, white papers, webinars, and podcasts. These publications highlight the latest work of SEI technologists in military situational analysis, software architecture, insider threat, honeynets, and threat modeling. This post includes a listing of each publication, author(s), and links where they can be accessed on the SEI website.

Automobiles are often referred to as "computers on wheels" with newer models containing more than 100 million lines of code. All this code provides features such as forward collision warning systems and automatic emergency braking to keep drivers safe. This code offers other benefits such as traffic detection, smartphone integration, and enhanced navigation. These features also introduce an increased risk of compromise, as demonstrated by researchers Chris Valasek and Charlie Miller (who work for Uber's Advanced Technology Center in Pittsburgh) in a July 2015 story for Wired, where they hacked into a Jeep Cherokee with a zero-day exploit. The Jeep Hack, as it has come to be known, highlighted an underlying issue for all vehicles: when automobiles are built, manufacturers focus on a threat model of potential risks that rely on physical defects, but do not include vulnerabilities that make a vehicle susceptible to intrusion and remote compromise. This blog post highlights the first phase of our research on making connected vehicles more secure by testing devices that connect into the vehicle itself.
In today's increasingly interconnected world, the information security community must be prepared to address vulnerabilities that may arise from new technologies. Understanding trends in emerging technologies can help information security professionals, leaders of organizations, and others interested in information security identify areas for further study. Researchers in the SEI's CERT Division recently examined the security of a large swath of technology domains being developed in industry and maturing over the next five years. Our team of analysts--Dan Klinedinst, Todd Lewellen, Garret Wassermann, and I--focused on identifying domains that not only impacted cybersecurity, but finance, personal health, and safety, as well. This blog post highlights the findings of our report prepared for the Department of Homeland Security United States Computer Emergency Readiness Team (US-CERT) and provides a snapshot of our current understanding of future technologies.
In 2014, approximately 1 billion records of personably identifiable information were compromised as a result of cybersecurity vulnerabilities. In the face of this onslaught of compromises, it is important to examine fundamental insecurities that CERT researchers have identified and that readers of the CERT/CC bloghave found compelling. This post, the first in a series highlighting CERT resources available to the public including blogs and vulnerability notes, focuses on the CERT/CC blog. This blog post highlights security vulnerability and network security resources to help organizations in government and industry protect against breaches that compromise data.
The Heartbleed bug, a serious vulnerability in the Open SSL crytographic software library, enables attackers to steal information that, under normal conditions, is protected by the Secure Socket Layer/Transport Layer Security(SSL/TLS) encryption used to secure the internet. Heartbleed and its aftermath left many questions in its wake:
- Would the vulnerability have been detected by static analysis tools?
- If the vulnerability has been in the wild for two years, why did it take so long to bring this to public knowledge now?
- Who is ultimately responsible for open-source code reviews and testing?
- Is there anything we can do to work around Heartbleed to provide security for banking and email web browser applications?
Software developers produce more than 100 billion lines of code for commercial systems each year. Even with automated testing tools, errors still occur at a rate of one error for every 10,000 lines of code. While many coding standards address code style issues (i.e., style guides), CERT secure coding standards focus on identifying unsafe, unreliable, and insecure coding practices, such as those that resulted in the Heartbleed vulnerability. For more than 10 years, the CERT Secure Coding Initiative at the Carnegie Mellon University Software Engineering Institutehas been working to develop guidance--most recently, The CERT C Secure Coding Standard: Second Edition--for developers and programmers through the development of coding standards by security researchers, language experts, and software developers using a wiki-based community process. This blog post explores the importance of a well-documented and enforceable coding standard in helping programmers circumvent pitfalls and avoid vulnerabilities.
According to a report issued by the Government Accountability Office (GAO) in February 2013, the number of cybersecurity incidents reported that could impact "federal and military operations; critical infrastructure; and the confidentiality, integrity, and availability of sensitive government, private sector, and personal information" has increased by 782 percent--from 5,503 in 2006 to 48,562 in 2012. In that report, GAO also stated that while there has been incremental progress in coordinating the federal response to cyber incidents, "challenges remain in sharing information among federal agencies and key private sector entities, including critical infrastructure owners."
