News Item: Exida Certifies Honeywell Safety Manager per ISASecure
Honeywell announced that their Safety Manager is the first platform to gain ISASecure certification on Monday, June 13, 2011 at the Honeywell User Group. Exida performed the certification per the ISASecure Embedded Device Security Assurance (EDSA) program which focuses on the security of industrial control devices such as PLC, DCS,…
News Item: WEBINAR RECORDING ADDED: Security Vulnerabilities: Stay One Step Ahead
One of the unexpected outcomes of STUXNET is the extent to which it has aroused the “security researcher” community and has turned their attention from commercial IT products to industrial automation and control systems. While their motives vary, from seeking recognition and monetary gain to intending to cause harm, the…
News Item: WEBINAR RECORDING ADDED: Simplified Safety Function Design Verification
In the performance based design framework of IEC 61511, the designer has the freedom to pursue cost optimization goals. However, the designs must be verified to meet the performance requirements of the standard. These design requirements can be simplified into three essential issues: 1. SIL capability 2. PFD avg 3.…
Blog Entry: The Weakest Link
One of the objectives of new performance based standards like IEC 61508 is to allow performance metrics (like PFDavg for low demand systems) to identify the weak links in any proposed design. Obviously, it is not necessary to put effort into design and spend money on areas of the design…

Blog Entry: Industrial automation is in the cross hairs of the hacker
As the details of STUXNET’s design unfolded last fall, like many, I was truly impressed by the pin-point precision that the malware authors used to ensure that their target, and only their target, was impacted by the virus. In this regard, STUXNET may be one of the most responsible piece…
News Item: Slides Available for 61508 Certification for Mechanical Devices in Safety Applications Webinar
This webinar describes the certification process for simple mechanical products like valves, actuators, or solenoid valves. Topics that will be discussed include: • IEC 61508 requirements for these certification projects • The ability to get random failure rates for each failure mode, proof test coverage, and useful life via the…
Blog Entry: Keep Risk Personal
We are fortunate that Risk Analysts have developed a logical framework of quantitative and semi-quantitative analysis techniques that allow us to assess and optimally mediate risk. And we all know that this is part of the Safety Lifecycle, a series of engineering steps/procedures that represent best safety practices. These are…
News Item: exida Announces Safety Lifecycle Web Series
In recent years, both the IEC 61508 and IEC 61511 standards have been adopted and are rapidly gaining momentum. These standards address both equipment design and system implementation, and have broad implications on Safety Instrumented Systems (SIS). The safety lifecycle can be segmented into three phases: 1. Analysis 2. Design…
Blog Entry: When is a Variable Frequency Drive a SIS?
It used to be that a pump would operate at a single speed dictated by a motor, thus fixing the pump curve. As the discharge flow decreased due to a restriction downstream, the pump outlet pressure would increase reaching its deadhead pressure. If the downstream piping and vessels were designed…

News Item: WEBINAR RECORDING ADDED: Achieving Software Security Assurance
In an October 2010 article, Mark Weatherford, vice president and chief security officer at NERC, was quoted as saying, “Addressing Stuxnet goes beyond using quality security controls. The industry needs to demand higher quality software that is free from defects.” The increased vulnerability of automation products due to software complexity…
