About

Ciaran Byrne

I am a SOC analyst with a technical background in ethical hacking, security infrastructure, digital forensics, and software development. I use this portfolio to document work that can be examined properly: what I built, how I approached it, what I observed, and where a prototype stopped.

Background

From networking and ethical hacking into security operations

My route into cyber security began with school-level security classes and home labs in Glasgow. I completed an HNC in Cyber Security and Networking at City of Glasgow College, followed by a BSc (Hons) in Ethical Hacking at Abertay University. The degree included a period of study at Champlain College in the United States.

The work moved across networking, operating systems, programming, authorised security assessment, digital forensics, cloud-connected hardware, and cyber-range engineering. I now bring that mixed background into SOC work, where technical findings need to become a clear investigation, decision, or escalation.

Progression

Education and technical development

  1. SOC analyst

    Security operations work supported by practical investigation, scripting, networking, and defensive research experience.

  2. BSc (Hons) Ethical Hacking, Abertay University

    Advanced security, digital forensics, secure programming, IoT development, and an individual honours cyber-range project.

  3. HNC Cyber Security and Networking, City of Glasgow College

    Networking, systems administration, and the technical foundations used throughout later security work.

Approach

Controlled work, documented honestly

I am most interested in the overlap between offensive understanding and defensive visibility. That includes how identity systems fail, what endpoint behaviour reveals, how network evidence survives an incident, and how infrastructure choices shape the quality of a security exercise.

Project pages distinguish my implementation from supplied lab material and third-party components. Historical work stays dated, prototypes remain prototypes, and detailed claims are tied to the evidence available from the work itself.
