SELinux Talk and Tutorial

David Quigley
Advanced Engineering & Development, Keyw Corporation

4:00pm Friday, 1 April 2011
Room 229 ITE, UMBC

Over a decade ago researchers at the National Information Assurance Research Lab at the NSA identified a need for flexible mandatory access controls to help provide a solid foundation for secure systems. This resulted in the development of the FLASK architecture, which has seen implementation in a number of operating systems. The most prominent implementation of FLASK is in the form of SELinux. Since the early days of SELinux adoption much work as been done to improve the utility and usability of SELinux. These enhancement have turned SELinux from a prototype research implementation into a robust access control mechanism that is used by a variety of customers world wide.

This talk is a from the ground up journey through SELinux. It starts with why do we need this technology and then moves through where to obtain it, how it works, and how to identify and solve problems associated with SELinux. In addition to these basics the talk also covers slightly more advanced topics such as hot to construct policy for new applications and hot to address customizations particular to your deployments.

David Quigley started his career as a Computer Systems Researcher for the National Information Assurance Research Lab at the NSA where he worked as a member of the SELinux team but has since left that position. David leads the design and implementation efforts to provide Labeled-NFS support for SELinux. David has previously contributed to the open source community through maintaining the Unionfs 1.0 code base and through code contributions to various other projects. David has presented at conferences such as the Ottawa Linux Symposium, the StorageSS workshop, LinuxCon and several local Linux User Group meetings where presentation topics have included storage, file systems, and security. David currently works as a Computer Science Professional for the Advanced Engineering and Development division at Keyw Corporation.

This talk is sponsored by the UMBC Linux Users' Group.

Making smartphones more intelligent

Mobile devices will provide better services if then can model, recognize and adapt to their users' context.

Our smartphones are quite capable, but not really very intelligent. They have more computational power than the supercomputers NASA used to reach the moon and are loaded with sensors, but lack "situational awareness" — an ability to understand their context and use that knowledge to provide better services for their users.

CSEE professor Tim Finin is one of the organizers of a workshop on Activity Context Representation: Techniques and Languages that is focused on the problems underlying making mobile devices more intelligent. The workshop will address techniques and systems to allow mobile devices model, reason about, and recognize the activities and context of their users and exploit those models to provide better services. The workshop is sponsored by the sponsored by the Association for the Advancement of Artificial Intelligence and will be held on August 7th and 8th in San Francisco as part of AAAI-11, the Twenty-Fifth Conference on Artificial Intelligence.

Finin is working with colleagues Anupam Joshi and Laura Zavala and students from the ebiquity lab on the NSF-sponsored Platys project that is working on this problem. The project is developing software for Android phones that uses machine learning algorithms to recognize their users' activities and their roles in them and selectively share this information with other devices based on user-defined privacy policies.

Yun Peng receives award from NIST for supply chain research

A supply chain is a system of organizations, people, technology, activities, information and resources involved in moving a product or service from supplier to customer.

Professor Yun Peng received a research award of $150,000 from the National Institute of Standards and Technology support work on "Integration Testing in Supply Chain Logistics" in the coming year. The research is focused on improving the systems that companies use to exchange and process information on services, products, orders and transportation. The objective is to reduce or eliminate problems that lead to late deliveries, inaccurate tracking, insufficient visibility, poor security, unreliable planning, and unnecessary disruptions in supply chains. The funds will be used to support research by UMBC students, postdocs and faculty in collaboration with NIST technical staff.

Startup City to stimulate urban entrepreneurship in Baltimore

Baltimore's Startup City

Baltimore entrepreneur and computer programmer Mike Subelsky wants to help strengthen the IT startup community in Baltimore and has created Startup City to give it jolt. The effort will fund up to ten groups that will receive free space, seed money and mentoring to develop their ideas during the summer of 2011.

The planning document describes what the program will offer the ten groups:

  • $15,000 in seed capital
  • Weekly master classes with experienced entrepreneurs
  • Regular access to mentors
  • Introductions to potential customers and follow-on investors
  • Free, beautiful office space collocated with the other participating companies
  • Legal, accounting, marketing, and technical assistance from Baltimore’s Emerging Technology Center
  • Vigorous coverage of their stories in our blog via video and written profiles
  • Exposure to investors, journalists, and business leaders at a Demo Day occurring at the end of the 12 weeks

See recent articles in in bmore and the Baltimore Sun.

"Applicants to Startup City, who will be selected based on a YouTube video they submit to the program's website, can be from anywhere in the world — though Baltimoreans are equally encouraged to apply. The final ten, chosen by consensus of all the mentors and investors involved in the program (after Beeman and Subelsky narrow down the initial pool) can be anyone from a single person with an idea to a formed team or company. Startup City is looking mainly for those who will be able to execute a successful project in twelve short weeks."
