Beats by Dre Data Analytics: Qualitative & Quantitative Insights Externship

A Beats by Dre externship focused on extracting qualitative and quantitative consumer insights from reviews and survey data using Python and AI-assisted tools.

Data AnalysisPython

Overview

During my externship with Beats by Dre, I gained hands-on experience in data analytics, focusing on qualitative and quantitative insights. I applied AI tools and Python to decode consumer conversations, uncover market trends, and create visual representations of data. This project enhanced my understanding of consumer behavior and informed strategic decision-making processes.

Overview

The externship exercised offensive and defensive techniques against a simulated smart-marina IoT deployment. Work included probing device behaviors, implementing network-level and device-level defenses, and documenting a security playbook. Deliverables combined attack demonstrations with concrete mitigation configurations.

What I've accomplished

I produced a consolidated STRIDE-based threat model for the Grand Marina system, including a PDF report and a visual threat-model card that documented identified threats and areas needing further practice.

Project breakdown

The module introduced the Grand Marina system, I mapped devices and data flows, applied STRIDE to identify threats, and produced a threat model PDF and a visual threat-model card that documented attack paths and prioritized controls.
