Welcome to the exciting world of OPUS Publishing's Owl House, the secure automation system developer's resource since 1999. Secure automation systems require two fundamental behaviors: strong access control and protection of the information transmitted or residing in data repositories. Owl House is a collection of publications by two old guys with contributions by many young guys. The old guys publish from experience; the young guys do so from an inexhaustible reserve of energy. The old guys want clarity; the young guys want performance. The old guys seek elegance and beauty; the young guys want results. Together we produce publications we hope you will find informative, challenging and entertaining. We tinker, break stuff, figure things out, and pass the information to you. We explain emerging communication technologies for substation automation, explore trends, and show you how to use this knowledge for good instead of evil. Thank you for coming.
Take a tutorialTutorials are at the heart of secure communication technology; one example is electric power substation automation. Penned by WiseOwls and a bevy of contributors, our tutorials walk you through the basics and then let you get your hands dirty with detailed how-to projects. Whether you're just starting out, are looking to expand your skills, need to brush up on basic principles, want to build an integrated automation system, or are ready for system test, we've got it covered. Click here to take the tutorial tour. Get your questions answeredIf you want something a little more focused, we have a slew of articles and commentary, covering just about every substation automation topic you've ever heard of. We've divided all our content into two webs: a public web where you are now, and a subscribers web for authorized users of the OPUS Subscription Service. Public web

| In the public web you will find newsletters that are published every two months. The newsletter usually contain a Publisher's Corner" and a "Call to Action". Click here to see the newsletters. | |
| You will also find a calendar of events for information security, communication security and related automation venues. Click here to see the calendar. | |
| You can use the hotlinks provided to access web and FTP sites for documents placed in the public domain by selected standards organizations and study committees. Click here to browse these hotlinks. | |
| You can also use the hotlinks to browse vendors and consultant web sites that are offering products and services for secure automation systems. Click here to browse these hotlinks. |

| As a subscriber you will have access to Que Pasa, Resource Library, and Interactive Workshop. | |
| Our subscribers use Que Pasa to keep up-to-date on the status of activities in the many venues that directly affect the development of secure automation systems; e.g., IEEE, IEC, WEI, ISA and CIGRE. | |
| Our subscribers also use the Resource Library to browse the glossary, list of applicable standards, and the list of definitive text books. | |
| Using the Unified Modeling Language (UML), the Extensible Markup Language (XML), and Abstract Syntax Notation One (ASN.1), WiseOwls tinker, break and eventually develop stable reusable secure communication components. Our subscribers use these components to develop applications for their IEDs, or to build-out the operating procedures for secure automation systems. | |
| Test scenarios for component testing and system testing are also developed by WiseOwls. These scenarios include detailed transaction sequences between IEDs, and within each transaction the measurement taps that are needed to evaluate performance are clearly identified. Our subscribers use these test scenarios as the basis for their product testing and system testing. | |
| Our subscribers use the Interactive Workshop to share their opinion about a specific secure automation issue. | |

OPUS Publishing's consulting services are designed to leverage the
knowledge base of the standards development and study committee venues.

Prototype test and evaluation is an absolute necessity to develop a
target substation automation architecture that is extensible for new
technologies as they become available. OPUS Publishing and their associates
provide the technical "know how" to develop a center of excellence
for test and evaluation.
