As our world becomes increasingly software-reliant, reports of security issues in the interconnected devices that we use throughout our day (i.e., the Internet of Things) are also increasing. This blog post discusses how to capture security requirements in architecture models, use them to build secure systems, and reduce potential security defects. This post also provides an overview of our ongoing research agenda on using architecture models for the design, analysis, and implementation of secure cyber-physical systems and to specify, validate, and implement secure systems.
This is the third installment in a series of three blog posts highlighting seven recommended practices for monitoring software-intensive system acquisition (SISA) programs. This content was originally published on the Cyber Security & Information Analysis Center's website online environment known as SPRUCE (Systems and Software Producibility Collaboration Environment). The first two posts in the series explored the challenges to monitoring SISA programs and presented the first five recommended best practices:
- Address in contracts
- Set up a dashboard
- Assign and train staff in its interpretation
- Update regularly
- Discuss in program reviews and as needed
This post, which can be read in its entirety on the SPRUCE website, will present the final two recommendations, as well as conditions that will allow organizations to derive the most benefit from these practices.

Today's computer systems often contain millions of lines of code and are constructed by integrating components, many of which are authored by various third parties. Application Programming Interfaces (APIs) are the glue that connects these software components. While the SEI and others have placed significant emphasis on developing secure coding practices, there has not been an equal emphasis placed on APIs. This blog post describes our recent research that aims to provide specific guidance to API designers to help them deal with the security issues regarding development of APIs.
In 2015, the SEI blog launched a redesigned platform to make browsing easier, and our content areas more accessible and easier to navigate. The SEI Blog audience also continued to grow with an ever-increasing number of visitors learning more about our research in technical debt, shift-left testing, graph analytics, DevOps, secure coding, and malware analysis. In 2015 (from January 1 through December 15), the SEI blog logged 159,604 visits and sessions (we also switched analytics platforms mid-year), a 26 percent increase in traffic from the previous year. This blog post highlights the top 10 posts published in 2015. As we did with our mid-year review, we will include links to additional related resources that readers might find of interest. We also will present the posts in descending order beginning with the 10th most popular post of 2015 and counting down to number one.

The federal government is facing a shortage of cybersecurity professionals that puts our national security at risk, according to recent research. "As cyber attacks have increased and there is increased awareness of vulnerabilities, there is more demand for the professionals who can stop such attacks. But educating, recruiting, training and hiring these cybersecurity professionals takes time," the research states. Recognizing these realities, the U. S. Department of Homeland Security (DHS) National Cyber Security Division (NCSD) enlisted the resources of the to develop a curriculum for a Master of Software Assurance degree program and define transition strategies for implementing it. This blog post presents an overview of the Master of Software Assurance curriculum project, including its history, student prerequisites and outcomes, a core body of knowledge, and a curriculum architecture from which to create such a degree program.
Malicious attackers and penetration testers can use some of the same tools. Attackers use them to cause harm while penetration testers use them to bring value to organizations. In this blog post, I've partnered with colleagues Jason Frank and Will Schroeder from The Veris Group's Adaptive Threat Division to describe some of the common penetration testing tools and techniques that can greatly benefit network defenders. While this blog post cannot cover all the techniques and shortcuts we use in the field, we do describe a set of 10 tactics that provide very little network disruption, are easy to use, and freely available.
It's the holiday season, a traditionally busy time for many data centers as online shopping surges and many of the staff take vacations. When you see abnormal traffic patterns and overall volume starts to rise, what is the best way to determine the cause? People could be drawn to your business, and you will soon need to add surge capacity, or maybe you are in the beginnings of a denial-of-service attack and need to contact your service provider. This blog post highlights recent work by CERT researchers to help organizations gain cyber situational awareness, which is based on network flow, and provides a tool to gain invaluable insights into ways your network is being used. More importantly, it helps you decide how to respond to changes in the online environment.
