An autonomous system is a computational system that performs a desired task, often without human guidance. We use varying degrees of autonomy in robotic systems for manufacturing, exploration of planets and space debris, water treatment, ambient sensing, and even cleaning floors. This blog post discusses practical autonomous systems that we are actively developing at the SEI. Specifically, this post focuses on a new research effort at the SEI called Self-governing Mobile Adhocs with Sensors and Handhelds (SMASH) that is forging collaborations with researchers, professors, and students with the goal of enabling more effective search-and-rescue crews.
It's undeniable that the field of software architecture has grown during the past 20 years. In 2010, CNN/Money magazine identified "software architect" as the most desirable job in the U.S. Since 2004, the SEI has trained people from more than 900 organizations in the principles and practices of software architecture, and more than 1,800 people have earned the SEI Software Architecture Professional certificate. It is widely recognized today that architecture serves as the blueprint for both the system and the project developing it, defining the work assignments that must be performed by design and implementation teams. Architecture is the primary purveyor of system quality attributes, which are hard to achieve without a unifying architecture; it's also the conceptual glue that holds every phase of projects together for their many stakeholders. This blog posting--the final installment in a series--provides lightly edited transcriptions of presentations by Jeromy Carriere and Ian Gorton at a SATURN 2012 roundtable, "Reflections on 20 Years of Software Architecture."
The Department of Defense (DoD) has become deeply and fundamentally reliant on software. As a federally funded research and development center (FFRDC), the SEI is chartered to work with the DoD to meet the challenges of designing, producing, assuring, and evolving software-reliant systems in an affordable and dependable manner. This blog post--the first in a multi-part series--outlines key elements of the forthcoming SEI Strategic Research Plan that addresses these challenges through research and acquisition support and collaboration with DoD, other federal agencies, industry, and academia.
As part of our mission to advance the practice of software engineering and cybersecurity through research and technology transition, our work focuses on ensuring the development and operation of software-reliant Department of Defense (DoD) systems with predictable and improved quality, schedule, and cost. To achieve this mission, the SEI conducts research and development (R&D) activities involving the DoD, federal agencies, industry, and academia. As we look back on 2012, this blog posting highlights our many R&D accomplishments.
Occasionally this blog will highlight different posts from the SEI blogosphere. Today's post by Paulo Merson, a senior member of the technical staff in the SEI's Research, Technology, and System Solutions Program, is from the SATURN Network blog. This post explores Merson's experience using Checkstyle and pre-commit hooks on Subversion to verify the conformance between code and architecture.
The majority of research in cyber security focuses on incident response or network defense, either trying to keep the bad guys out or facilitating the isolation and clean-up when a computer is compromised. It's hard to find a technology website that's not touting articles on fielding better firewalls, patching operating systems, updating anti-virus signatures, and a slew of other technologies to help detect or block malicious actors from getting on your network. What's missing from this picture is a proactive understanding of who the threats are and how they intend to use the cyber domain to get what they want. Our team of researchers--which included Andrew Mellinger, Melissa Ludwick, Jay McAllister, and Kate Ambrose Sereno--sought to help organizations bolster their cyber security posture by leveraging best practices in methodologies and technologies that provide a greater understanding of potential risks and threats in the cyber domain. This blog posting describes how we are approaching this challenge and what we have discovered thus far.
Sabotage of IT systems by employees (the so-called "inside threat") is a serious problem facing many companies today. Not only can data or computing systems be damaged, but outward-facing systems can be compromised to such an extent that customers cannot access an organization's resources or products. Previous blog postings on the topic of insider threat have discussed mitigation patterns, controls that help identify insiders at risk of committing cyber crime, and the protection of next-generation DoD enterprise systems against insider threats through the capture, validation, and application of enterprise architectural patterns. This blog post describes our latest research in determining the indicators that insiders might demonstrate prior to attacks.
It is widely recognized today that software architecture serves as the blueprint for both the system and the project developing it, defining the work assignments that must be performed by design and implementation teams. Architecture is the primary purveyor of system quality attributes that are hard to achieve without a unifying architecture; it's also the conceptual glue that holds every phase of projects together for their many stakeholders. Last month, we presented two posting in a seriesfrom a panel at SATURN 2012 titled "Reflections on 20 Years of Software Architecture" that discussed the increased awareness of architecture as a primary means for achieving desired quality attributes and advances in software architecture practice for distributed real-time embedded systems during the past two decades.
