OWASP Ottawa
Hello Ottawa and the World, Welcome to your OWASP Ottawa Chapter!
Who We Are
We are a place to meet local developers and information security professionals, share ideas, and learn.
You will find us informal, approachable, and thankful for your assistance. We encourage and welcome beginners. We are an open, tolerant, and inclusive organisation that accepts all races, genders, creeds, abilities, things, and ideas with the exception of one - Hate: Hate has no home at OWASP Ottawa.
OWASP Ottawa events are completely free. We will never charge for access to any of our events.
What We Do
We provide a mix of InfoSec talks, hands on training sessions, and special interest discussion groups. We hold monthly meetups at the STEM Building of the University of Ottawa. We hold occassional workshops on a variety of security topics.
We are always looking for new ideas for events so let us know if you have an idea.
You can submit an idea at any point in time at the following link:
OWASP Ottawa Speaker Submission Form.

Abstract:
Blackout at Scale: A Multi-Perspective Study of Iran’s Internet Shutdown with Ali Sadeghi Jahromi
This talk presents the Internet shutdowns in Iran during January and March 2026 using a multi-plane measurement approach that combines passive Internet-wide scanning, active probing, and BGP routing analysis. We show how these disruptions were enforced through centralized forwarding-plane null-routing while BGP announcements remained largely unchanged, effectively hiding outages from traditional routing-based monitoring. Using global scan data, we analyze how visible host populations collapse and fluctuate during shutdown periods, including apparent anomalies that reflect measurement artifacts rather than true recovery. Through active probing of thousands of Iranian prefixes from multiple global vantage points, we find that most infrastructure becomes consistently unreachable in a centrally coordinated manner, with only a small subset of networks remaining accessible. We further identify systematic structural exemptions, including academic networks and major CDN infrastructure, that exhibit distinct behavior under shutdown conditions. Together, these results demonstrate that different measurement perspectives provide complementary but individually limited views of large-scale Internet control, highlighting the need for a multi-plane approach to accurately interpret modern Internet shutdowns.
Speaker:
Ali Sadeghi Jahromi is a Lead Cybersecurity Researcher at the Cyber Security Evaluation and Assurance (CyberSEA) Research Lab at Carleton University, where he collaborates with General Dynamics Mission Systems-Canada on applied cybersecurity research. Ali received both his Master’s degree and PhD in Computer Science from Carleton University, specializing in Internet security. His research focuses on Internet measurement, secure protocol design and evaluation, threat modelling, and the application of artificial intelligence in cybersecurity.
If you are coming into town by car to attend a meetup then you may have questions about parking. Below is a Ottawa University Campus parking map:
Alternatively, you can try your luck on street parking in Sandy Hill or in the Triangle on the other side of the canal (you can cross over using the Corkstown pedestrian bridge).
Even better, use the train as there is a station on campus.
