The Latest Research in Software Engineering and Cybersecurity

In my preceding blog post, I promised to provide more examples highlighting the importance of software sustainmentin the US Department of Defense (DoD). My focus is on certain configurations of weapons systems that are no longer in production for the United States Air Force, but are expected to remain a key component of our defense capability for decades to come, and thus software upgrade cycles need to refresh capabilities every 18 to 24 months. Throughout this series on efficient and effective software sustainment, I will highlight examples from each branch of the military. This second blog post describes effective sustainment engineering efforts in the Air Force, using examples from across the service's Air Logistics Centers (ALCs).

As part of an ongoing effort to keep you informed about our latest work, I'd like to let you know about some recently published SEI technical reports and notes. These reports highlight the latest work of SEI technologists in embedded systems, risk management, risk-based measurement and analysis, early lifecycle cost estimation, and techniques for detecting data anomalies. This post includes a listing of each report, author(s), and links where the published reports can be accessed on the SEI website.

Many DoD computing systems--particularly cyber-physical systems--are subject to stringent size, weight, and power requirements. The quantity of sensor readings and functionalities is also increasing, and their associated processing must fulfill real-time requirements. This situation motivates the need for computers with greater processing capacity. For example, to fulfill the requirements of nano-sized unmanned aerial vehicles (UAVs), developers must choose a computer platform that offers significant processing capacity and use its processing resources to meet its needs for autonomous surveillance missions. This blog post discusses these issues and highlights our research that addresses them.

Our SEI blog has included thoughtful discussions about sustaining software, such as the two-part post "The Growing Importance of Sustaining Software for the DoD." Software sustainment is growing in importance as the lifetimes of hardware systems greatly exceed the normal lifetime of software systems they are partnered with, as well as when system functionality increasingly depends on software elements. This blog post--the first in a multi-part series--provides specific examples of the importance of software sustainment in the Department of Defense (DoD), where software upgrade cycles need to refresh capabilities every 18 to 24 months on weapon systems that have been out of production for many years, but are expected to maintain defense capability for decades.

The SEI has been actively engaged in defining and studying high maturity software engineering practices for several years. Levels 4 and 5 of the CMMI (Capability Maturity Model Integration) are considered high maturity and are predominantly characterized by quantitative improvement. This blog posting briefly discusses high maturity and highlights several recent works in the area of high maturity measurement and analysis, motivated in part by a recent comment on a Jan. 30 postasking about the latest research in this area. I've also included links where the published research can be accessed on the SEI website.

We use the SEI Blog to inform you about the latest work at the SEI, so this week I'm summarizing some video presentations recently posted to the SEI website from the SEI Technologies Forum. This virtual event held in late 2011 brought together participants from more than 50 countries to engage with SEI researchers on a sample of our latest work, including cloud computing, insider threat, Agile development, software architecture, security, measurement, process improvement, and acquisition dynamics. This post includes a description of all the video presentations from the first event, along with links where you can view the full presentations on the SEI website.

Over the past several years, the SEI has explored the use of Agile methods in DoD environments, focusing on both if and when they are suitable and how to use them most effectively when they are suitable. Our research has approached the topic of Agile methods both from an acquisition and a technical perspective. Stephany Bellomo described some of our experiences in previous blog posts What is Agile? and Building a Foundation for Agile. This post summarizes a project the SEI has undertaken to review and study Agile approaches, with the goal of developing guidance for their effective application in DoD environments.
