June General Meeting

SCADA Security - What's Broken and How To Fix It

Speaker: Andrew Ginter, VP Industrial Security, Waterfall Security Solutions

Andrew Ginter

How can we patch everything, when changed code risks malfunction of our physical, industrial processes? How many false alarms does our intrusion system generate? If "the perimeter is dead," and all software is vulnerable, what hope is there?

Asking the wrong questions has led entire industries to deploy inadequate defenses. We need better questions. Should we let any stranger turn our dials and throw switches? When we detect compromise, can we restore equipment and human lives "from backups?"

Preventing compromise is critical. The only way to compromise a control system is to breach a perimeter. Important systems always have a perimeter.

Andrew will be speaking to these and related topics from his new book.

Andrew Ginter is the VP Industrial Security at Waterfall Security Solutions, an Adjunct Professor at Michigan Technological University, and an author and speaker on SCADA Security topics. He has led teams developing SCADA, IT/OT middleware, and SCADA security products, and was awarded patents for middleware and SCADA security technologies. He holds Applied Mathematics and Computer Science degrees from the University of Calgary, and is located in Calgary, Alberta.

"Sounds familiar. Déjà vu all over again," you ask?

The original presentation attempt by Andrew Ginter at our September 2016 general meeting generated so much discussion that Andrew was only able to complete the first third of his presentation.

This time we have undertaken, if required, to gavel the room through his complete presentation.

Prior to this meeting, our members are encouraged to finish reading or brush up on Andrew's book which he kindly provided to all CUUGers.

Come and join us for a lively evening of exploration.

April General Meeting

YYCIX: Calgary Internet Exchange

Speaker: Theo de Raadt, Founder, OpenBSD

Five years ago, Calgary was the most populous city in the G8/G20 without an internet exchange. As a result, so-called boomerang routes were very common. Traffic sent from one local network to another local network would loop through Vancouver, Seattle, Toronto, Chicago, or even further afield.

An internet exchange is really just an "open switch" where networks can interconnect. Some other internet-improving services can also be established at this point to make our Alberta networking experience better.

YYCIX was built by a collection of volunteers who made arrangements with local partners to bring this function to the City. Theo de Raadt was one of those volunteers, and he will present an update on how things have progressed and where they may be headed next.

Theo de Raadt is widely recognized as a world class security expert. In October 1995, Theo founded the OpenBSD project. OpenBSD is the most secure of the publicly available operating systems.

In 1999, Theo created OpenSSH with other members of OpenBSD. It is now incorporated into all Unix systems plus hundreds of other network enabled products. It has become the most "vendor re-used" piece of open source software, with more than 95% of the SSH market.

Theo was awarded the Free Software Foundation's 2004 Award for the Advancement of Free Software, for recognition as founder and project leader of the OpenBSD and OpenSSH projects. His work has also led to significant contributions to other BSD distributions and GNU/Linux. Of particular note is Theo's work on OpenSSH, his leadership of OpenBSD, his commitment to Free Software and his advancement of network security.

Theo is also well known for his advocacy of free software drivers. He has long been critical of developers of Linux and other free platforms for their tolerance of non-free drivers and acceptance of non-disclosure agreements.

March General Meeting

ERPNext: Open Source Enterprise Resource Planning for Small Business

John Clarke, ERPNext Champion, Consultant at Apropos Computing

John Clarke

Up to now only Big Business has used Enterprise Resource Planning (ERP) software. In basic terms ERP aims to standardize and automate processes to streamline how a business operates: ERP lets departments and workers connect and share data and processes, so analysts and executives can quickly spot and resolve business performance problems.

The ERP tools a firm selects depends on what process they aim to improve and whether they sell products or services: Businesses that sell products may have manufacturing, supply chain or distribution functions that the ERP system must address. For organizations that sell services, an ERP must support project management budgets, task and resource scheduling, and billing.

First SAP in 1973 then later Oracle, Microsoft and others provided Tier 1 ERP solutions at a huge cost to licence and implement. But now powerful open source ERPs target Small Business, who struggle with the same problems as Big Business: To master systems vital for them to organize and respond, so they can compete and grow.

With a nascent Foundation (think: Apache, Mozilla, Eclipse) and a GPL3 licence, ERPNext may disrupt its open source ERP competition.

John will share some of ERPNext's metaprogramming features that let everyday users self-implement and customize their ERP to suit.

John has degrees in Computer Science (Calgary) and Survey Science (Toronto), and loves to bike, hike and travel. From his eight-year stint responsible for Quality Assurance on a Java application project (for several years a 40+ developer team), John knows first hand how and why Test Driven Design, Agile development, and Continuous Integration with Automated Build and Test works.

November General Meeting

O-NET: How Olds, Alberta, Acquired Town-Wide Fibre Optic Internet

Speakers: Robin Harder, Chief Technologist, O-NET; and Nathan Kusiek, Director of Business Development, O-NET

Robin Harder Nathan Kusiek

Have you ever been frustrated with your telecommunications company over slow Internet speeds, small data caps, long on-hold times, or complex and ever-increasing prices? Have you thought that there has to be a better way with today's technology? O-NET is a direct result of people thinking like you.

O-NET is a technology company founded in Olds, Alberta that specializes in Internet, telephony and television. Over the past four years O-NET has installed a town-wide fibre optic network, developed unique Internet, voice, PBX, and television services, and connected thousands of subscribers. They were the second ISP in North America to offer gigabit Internet, losing the race to Google Fiber. O-NET is disrupting the telecommunications industry in Alberta, showing that small nimble organizations and communities can develop and compete with the incumbents.

Join two of O-NET's key personnel for a presentation and open dialogue about what it takes to start a telco. They will discuss open access networks, bandwidth as a utility, business operating models that promote competition, television channel procurement, and how community engagement and sustainability tie into O-NET's success.

Nathan Kusiek is the Director of Business Development for O-NET. From day to day his responsibilities at O-NET vary. He is responsible for marketing, communications, product development and pricing at O-NET. He spends his days analyzing data and evaluating business cases for profitability versus sustainability and value.

Robin Harder is the Chief Technologist for O-NET. He has nearly 20 years of experience in information technology management, consulting and direction at companies in Calgary and Central Alberta. At O-NET, he is responsible for everything that plugs in and gets buried. This includes customer premise equipment, core routers and switches to fibre connectors to network access points.
