Vulnerability Analysis Developer

Jul 2021 – Present · 4 yrs 10 mos · Stockholm · On-site

As a Vulnerability Analysis Developer in Ericsson, I work on securing Baseband and Radio products through quarterly vulnerability testing that includes scanning, fuzzing, flooding, and protocol‑level analysis using tools like Nessus, Defensics, and internal Ericsson frameworks. I also evaluate new security testing tools and methodologies to strengthen our automation and coverage. My work includes contributing to Ericsson’s first‑time ORAN feature testing and supporting research to improve Air Interface protocol testing. I collaborate closely with cross‑functional teams to refine testing strategies and enhance the overall security and reliability of Ericsson’s network solutions.

Research Paper Title: Novel Physical Layer Security using Adaptive Modulation Scheme for Improved Confidentiality
The major contributions by this paper are as follows:
To enhance confidentiality and to minimise SER, even at low SNR, a novel adaptive modulation scheme has been
proposed.
The performance of the proposed scheme is evaluated with two types of attacker models. The effects of SNR and
phase estimation errors on SER have been analysed for certain guard intervals.
