Deploying Incompatible Unmodified Dynamic Analyses in Production via Multi-version Execution
Imperial College London –
Popular dynamic analysis tools such as Valgrind and compiler sanitizers are
effective at finding and diagnosing challenging bugs and security vulnerabilities. However, they cannot be combined on the same program execution, and incur a high overhead, which typically prevents them from being
used in production.
In this talk I will present the FreeDA system which enables to deploy existing
multiple incompatible dynamic analysis tools without requiring any modification
and while masking their overhead. FreeDA levarages on multi-version execution,
in which the dynamic analyses are run alongside the production system. FreeDA is applicable in several common scenarios, involving network servers and interactive applications. In particular, FreeDA is able to deploy Valgrind and
Clang’s sanitizers to high-performance servers, such as Ngninx and Redis, and
interactive applications, such as Git and HTop.
Luís Pina is currently a post-doc at the Software Reliability Group (SRG) at
Imperial College London. He was part of the Programming Languages Group (PLUM) at University of Maryland from 2012 to 2015, and part of the Software
Engineering Group (ESW) at INESC-ID in Lisbon from 2009 to 2012.
He holds a PhD on Computer Science from Instituto Superior Técnico, University of Lisbon, Portugal. He developed his dissertation under the supervision of Prof. Luís Veiga and Prof. Michael Hicks, focusing on making Dynamic Software Updates (DSU) practical.
Luís is now working on Multi-Version Execution, with Prof. Cristian Cadar,
exploring how to use this technique to deploy costly dynamic analysis techniques in production environments.

International Day of Women and Girls in Science: Inês Lynce at Pavilhão do Conhecimento
Inês Lynce — President of the Board of Directors of INESC-ID, Automated Reasoning and Software Reliability (ARSR) researcher, CMU Portugal National Co-Director and Full Professor at Instituto Superior Técnico — will participate in the Ciência Viva celebrations for the 2023 International Day of Women and Girls in Science (IDWGIS) on 11 February.
Inês Lynce is one of the invited speakers of the Roundtable “Pergunta-me o que é ser cientista” (Ask me what it means to be a scientist; 15:00-16:30 at Auditório José Mariano Gago, Pavilhão do Conhecimento), where female researchers and university students from different areas of science (engineering, information technology, physics and mathematics) will speak about what it means to be a “woman in science” in each of their fields.
The IDWGIS at Pavilhão do Conhecimento will be entirely dedicated to promoting activities to encourage and promote access for all girls and women to training and education in the field of science.
Here’s the full agenda.
