Topic

Toward Proactive Mitigation of Advanced Multi-tier Botnets

Date and Time

February 8, 2012 from 5 pm – 6 pm

Abstract

In this talk I will present our on-going efforts to mitigate the advanced botnets. Botnet is a network of compromised machines, exploited to carry out malicious acts such as spam, phishing, denial of service attacks, and stealing sensitive data such as passwords and banking credentials. The detection and mitigation of these botnets have proven to be quite challenging. Malware authors, supported by a thriving underground economy, have demonstrated professional quality sophistication in creating codes highly adaptive to existing mitigation efforts.

We have explored a series of botnet mitigation approaches directed toward (i) creating new analysis and de-obfuscation methods to rapidly expose the botnets’ command and control protocols in a timely manner, (ii) in-depth analysis to explore the fundamental limits and weaknesses of the advanced botnet architecture, and (iii) designing an effective enumerator (or “mapping” of bot networks) to locate bot-infected hosts on the Internet.

Our research direction fundamentally differs from existing Intrusion Detection System (IDS) approaches. Unlike IDS, which is geared towards protecting local hosts within its perimeter, an enumerator will enable identification of both local and remote infections. Identifying remote infections is crucial, given that there are numerous computers on the Internet that are not under the protection of IDS-based systems. The resulting enumeration has been used for spam blocking, firewall configuration, DNS rewriting, and alerting sys-admins regarding local infections.

Rice Hall Opens

Technology that could transform life as we know it and improve the human condition – that’s the vision behind the University of Virginia School of Engineering and Applied Science’s new Rice Hall Information Technology Engineering Building. The building will open at the beginning of the fall semester for classes.

The state-of-the-art space will allow faculty and students to conduct research and learn in such areas as high-performance computing, computer visualization, computer security, energy conservation, wireless communications, telemedicine, virtual reality, distributed multimedia and distance learning.

As the new home for the Department of Computer Science and the Computer Engineering Program, Rice Hall will also feature unique space for lab work, lectures and studying.

“This building is a huge step forward for the Engineering School,” said Dean James H. Aylor at Rice Hall’s groundbreaking in April 2009. “With labs and study areas designed for collaborative research, and facilities to enhance our distance-education programs, this building will benefit the Engineering School, the University and citizens of the commonwealth for years to come.”

The creation of Rice Hall was made possible by a lead gift of $10 million from Paul and Gina Rice, through the Rice Family Foundation.

On the Rice Hall website, Paul Rice, a 1975 electrical engineering alumnus, wrote: “The real promise of what will happen here is the 21st-century extension of the Academical Village and what will be made possible by the technologies that are used, developed and explored in these places. The village won’t simply exist then in these buildings or on this campus, but across the state, across the nation and globe. We have only really begun to understand the way in which these technologies can enhance human performance and accomplishment and how they can improve the human condition.”

Additional funding for the $65.5 million Rice Hall project came from U.Va., the state and from other U.Va. alumni and friends.

The building was designed by Bohlin Cynwinski Jackson and is being constructed by W.M. Jordan Company.

Located at the corner of Whitehead and Stadium roads behind Olsson Hall, Rice Hall consists of six stories covering 100,000 square feet. It is designed to be Leadership in Energy & Environmental Design-certified, commonly known as LEED. It also will be at the forefront of air and power technology, noted senior project manager Craig Hilten of Facilities Management.

Rice Hall’s “chilled beams” use water instead of air to remove heat from rooms – a new technology for University facilities. With sophisticated technologies for heating, cooling and lighting, and including energy recovery systems, Rice Hall also will function as a living laboratory on energy use.

When it opens, students and faculty going about their daily routines in the building will help researchers learn how to optimize the latest energy technologies for large buildings. The building’s instrumentation systems will collect data that will allow managers to optimize its energy consumption. The research also could inform behaviors, such as closing doors or powering down equipment to help reduce energy consumption.

Both undergraduate and graduate students will benefit from specialized lab spaces on all six floors. The largest is the Design Laboratory, located on the first floor, where Introduction to Engineering classes will be taught. With folding doors, it opens and connects to the courtyard, providing space for lab work that must be completed outside.

Also, space in the basement provides the appropriate environment for lab procedures that require specialized lighting. They include the Light Measurement Laboratory and the Visualization Lab.  The floors, ceilings and walls are black, reducing stray light and enhancing image presentation.

Equipped with enhanced audio and video capabilities, Rice Hall also supports the Engineering School’s distance-learning initiatives and teleconferencing – especially benefitting the PRODUCED in Virginia engineering program, in which students earn a four-year engineering degree from U.Va. while attending local community colleges.

Other features of Rice Hall include a 150-seat lecture hall, a cyber cafe, an Einstein’s Bagels eatery and a lobby – all located on the first floor.

Rice Hall will be formally dedicated Nov. 18.

UVa Microsoft Research Fellow

July 12, 2010 — abhi shelat, assistant professor of computer science at the University of Virginia’s School of Engineering and Applied Science, was recently selected as a Microsoft Research Faculty Fellow for 2010.

The fellowship award includes an unrestricted cash gift of $200,000 and access to other Microsoft resources, such as software, invitations to conferences and engagements with Microsoft Research, the company’s worldwide research organization.

shelat will use the award to support his research in the field of computer cryptography, which is essential for securing information that is exchanged on everything from wireless networks to automated teller machines to Internet banking sites.

“This award recognizes abhi’s brilliance as a researcher and it will help him advance his work in the field of cryptography,” said Mary Lou Soffa, chair of the U.Va. Department of Computer Science. “We are honored to have him as a colleague.”

This year was particularly competitive because Microsoft combined the domestic and international competitions for the awards. There were only seven fellows chosen from Latin America and the Caribbean; Europe, the Middle East, and Africa; the United States; and Canada.

“abhi possesses a rare combination of vision and creativity that enables him to select highly original research topics that are both theoretically significant as well as applicable in practice,” said Gabriel Robins, a professor in the Department of Computer Science. “I found it refreshing that abhi also cares a great deal about teaching and pedagogy. We often have long conversations and exchange ideas about how to better explain to students deep and subtle theoretical concepts.”

Working While You Sleep…

Software That Carries Out Tasks On Behalf Of Sleeping Computers Could Lead To Energy Savings.

Technology Review (6/30, Graham-Rowe) reports, “Networked PCs are increasingly being left on 24/7 to allow for out-of-hours access by employees, says Yuvraj Agarwal, a professor of computer science at the University of California, San Diego.” Agarwal, along with other UCSD professors, developed an energy-saving solution wherein they “create a stripped down, virtual copy of a machine. Software running on a remote server maintains a version of a PC’s operating systems and applications. The software, called SleepServer, carries on tasks on behalf of the desktop machine while it is put into a low-energy sleep mode.” And, if “complex activity is required, the software wakes up the computer, says Agarwal, a process that typically takes less than 10 seconds.”

Roll-Up Computer

This from the recent AskBobRankin Geekly Update for 28 October 2009:

“The Rolltop computer is one of the coolest gadgets I’ve seen in a long time. It’s a laptop that literally rolls up like a newspaper, and unrolls into either a 17-inch flat screen or a tablet configuration. There’s just one problem, it only exists as a design concept. But the video is worth a look.”

Nuts and Bolts Editor’s Note:  Although just a “concept”, it is certainly an intriguing one!  Enjoy!  Getting to the video is a bit awkward, but click on Rolltop link above, then the link at the bottom of the resulting screen and be patient while the cookie displays!
