vulnerabities a top SCADA security story? Digital Bond has identified OPC vulnerabilities as one of the Top Ten SCADA Security Stories in 2007: "Lluis Mora and the team at Neutralbit sent 25 OPC server vulnerabilities to US-CERT in 2007. The affected vendors are slowly fixing these vulnerabilities which then are disclosed in vulnerability notes". Sadly, it turns out that just 3 of the 25 holes have been patched to date. |

Compliance Tests - new pre-releases available OPC Foundation has published new pre-release (evaluation) versions of most of the CTT modules, with various bug fixes. These downloads are available to OPC Foundation Corporate Members. A discussion has been set up on the OPC message board for reporting of any problems. |
| 2007-Dec-12 | Odd
Lots Catching up with some recent news items: - The November 2007 issue of OPC Foundation's "OPConnect" newsletter is available, along with back issues. Matrikon's Eric Murphy completed his overview of the DA 3.0 specification. A fine piece of work, though you'll still want the actual specification - OPC Foundation member or not. As Eric said in part 1, the OPC specs are (fortunately for all concerned) still readily and freely available. Software Toolbox acquired the OPC business of long-time toolkit vendor Northern Dynamic, and plans to retain the brand. ILS Technology has been making waves due to the OPC-UA support offered by its adopted by Softing. |

Foundation Bug Tracking System Many OPC developers may be unaware that OPC Foundation operates its own bug tracking and reporting system at https://www.opcfoundation.org/mantis/. Before reporting a bug or a specification fault, it would be worth checking this site. Many of the current issues relate to different parts of the UA specification. |

Components SDK reinstated The OPC Core Components SDK 3.00 is now available for download. The SDK includes the header files and IDL necessary to build an OPC application, and is available to both members and non-members of OPC Foundation.

| 2007-Apr-19 | OPC-UA leads
to unity between EDDL and FDT FDT and EDDL - the two competing standards for device definition and integration - have been brought together by the OPC Unified Architecture. At a meeting in March, it was agreed that the FDT Group would become a member of ECT (EDDL Cooperation Team) and work on defining a common OPC-UA Information Model for device descriptions. It had previously seemed likely that each group would define its own UA Information Model, even though they are both addressing the same basic problem. See the official announcement from Interkama for more information. |
| 2007-Apr-17 | Updated
installers for OPC Core Components Downloads for the OPC Core Components binaries have been upissued. The new versions fix problems with the installers and UAC (User Account Control) on Windows Vista - the binaries themselves are unchanged. See OPC Foundation downloads. |

OPC Message Board OPC Foundation has today announced that the Foundation's Message Board now has its own RSS feed. While an RSS feed can't thread messages in a way that a forum does, for many this will represent a very convenient way of keeping up with current debates in the OPC community. Subscribed. |
| 2007-Mar-20 | OPC server
vulnerabilities/patches The work of Neutralbit, presented at the recent S4 conference, has led to the announcement of 2 vulnerabilities in OPC servers, both of which are now patched. In each case, the fault relates to the server's failure to validate handles passed to it by a client. See US-CERT notes for NETxAutomation and Takebishi servers (via Digital Bond blog). |

| 2007-Feb-25 | Understanding
the OPC UA Information Model At the heart of the OPC Unified Architecture is the UA Information Model. The Information Model is an elegant construction which allows for tremendous flexibility when presenting process data, while continuing to support the well understood models of existing OPC specifications. Anyone looking to become familiar with UA will want to take in the Information Model at a very early stage. Eric Murphy's most recent blog post, Thoughts on the OPC UA Information Model, offers a great introduction. |

| 2007-Feb-10 | Major updates
to OPC redistributables, .NET API, sample code OPC Foundation has updated a large number of its code samples and redistributables. Most significant are new proxy/stub builds and an update of the .NET API to .NET 2.0. Also affected are sample code for DA, HDA and XML-DA. All code samples are now built with Visual Studio 2005.

| 2007-Feb-01 | S4 - OPC
security roundup The Digital Bond blog has a post covering the second day of the recent S4 conference on SCADA security, including 2 papers on vulnerabilities in OPC server implementations. Although many servers were shown to be robust, a large minority demonstrated significant problems. Standout remark concerns the submission of "25 advisories to US-CERT and CERT/CC for processing". It's encouraging that the automation business is at last waking up to such issues - clearly there's much more to come. |

in the spotlight (1) With security of automation systems coming under increasing scrutiny, the robustness of OPC applications is receiving more attention than ever before. Is this the first example of a remote code execution exploit arising from off-the-shelf OPC software? Credit to the vendor, ICONICS, for providing a timely hotfix. |
