AppEKG

AppEKG is a novel approach to providing better insight into how HPC applications behave in the production environment, an area where further introspection beyond the current practice is strongly needed. Centered on the idea of producing heartbeats from important application phases, AppEKG proposes this unifying idea as a way to support generic analyses that can be used across a wide variety of applications, thus avoiding application-specific issues

Paper

SStack

SStack is a software stack tool to manage package managers. It provides an ease of building common package managers with sane or site-specific defaults in a structural hierarchy. Moreover, using Lmod, we connected all the package managers and software installed using SStack and made them searchable across multiple stacks. This tool helped novice users manage their software stacks without needing extra help from system administrators to deal with package manager installations, dependencies, module configuration, and discoverability across stacks.

Paper

AGGIE-grid

The AGGIE-grid is a decentralized HTC cluster, which was deployed to help maximize the utilization of student lab machines with little or no interference to its regular usage by students.

Paper

Automated Vulnerability Analysis Tool (AVANT)

Developed an Automated Vulnerability Analysis Tool (AVANT), a vulnerability tool that is architecture-agnostic and reports vulnerability found from our test suite. AVANT is used to evaluate the security performance of different architectures. This was primary developed to test our OSFA, however, I made it applicable to other architectures for comparison studies of e.g., reduction of impact, overhead, and performance. AVANT contains source code of traditional memory corruption vulnerabilities in e.g., MITRE CWE list. In addition to the vulnerable source code, AVANT, compiles, runs the analysis and outputs the results. I collected the results and showed that for reported vulnerabilities different architectures may differ in their stack values/addresses which can lead to some other attacks on these architectures.

Internet of Things

Worked on capturing and analyzing data between IoT devices and smartphone on different setups. Specifically, the August Smart lock, Chromecast, TrackR Bravo, Wink light bulbs and hub, and Monster wireless speaker. After analyzing data captured between smartphone and IoT devices, I found that some of them are sending packed unencrypted.

Common Open Research Emulator(CORE)

Worked on assuring the secure communication between different nodes under spoofing attack, as well as a data forwarding attack. This was done by fixing the software bugs in aodv-uu to make Common Open Research Emulator work better. Moreover, I worked on fixing the implementation of jad-hoc in java and creating and testing topologies.
