Injecting chaos experiments into security log pipelines

Wednesday 12th of September 2018 11:53:37 PM

  • A healthcare IT foundation built on gooey clay
    Today, there was a report from the Solicitor General of Singapore about the data breach of the SingHealth systems that happened in July. These systems have been in place for many years. They are almost exclusively running Microsoft Windows along with a mix of other proprietary software including Citrix and Allscript. The article referred to above failed to highlight that the compromised “end-user workstation” was a Windows machine. That is the very crucial information that always gets left out in all of these reports of breaches. I have had the privilege of being part of an IT advisory committee for a local hospital since about 2004 (that committee has disbanded a couple of years ago, btw). [...] Part of the reason is because decision makers (then and now) only have experience in dealing with proprietary vendor solutions. Some of it might be the only ones available and the open source world has not created equivalent or better offerings. But where there are possibly good enough or even superior open source offerings, they would never be considered – “Rather go with the devil I know, than the devil I don’t know. After all, this is only a job. When I leave, it is someone else’s problem.” (Yeah, I am paraphrasing many conversations and not only from the healthcare sector). I recall a project that I was involved with – before being a Red Hatter – to create a solution to create a “computer on wheels” solution to help with blood collection. As part of that solution, there was a need to check the particulars of the patient who the nurse was taking samples from. That patient info was stored on some admission system that did not provide a means for remote, API-based query. The vendor of that system wanted tens of thousands of dollars to just allow the query to happen. Daylight robbery. I worked around it – did screen scrapping to extract the relevant information. Healthcare IT providers look at healthcare systems as a cashcow and want to milk it to the fullest extent possible (the end consumer bears the cost in the end). Add that to the dearth of technical IT skills supporting the healthcare providers, you quickly fall into that vendor lock-in scenario where the healthcare systems are at the total mercy of the proprietary vendors.

Linux Foundation for Sale

  • Open Source Summit EU Registration Deadline, Sept. 22, Register Now to Save $150 [Ed: Microsoft is the "DIAMOND" sponsor of this event, the highest sponsorship level! Linux Foundation, or the Zemlin PAC, seems to be more about Microsoft than about Linux.]

  • The Human Side of Digital Transformation: 7 Recommendations and 3 Pitfalls [Ed: New Zemlin PAC-sponsored and self-serving puff piece]
    Not so long ago, business leaders repeatedly asked: “What exactly is digital transformation and what will it do for my business?” Today we’re more likely to hear, “How do we chart a course?” Our answer: the path to digital involves more than selecting a cloud application platform. Instead, digital, at its heart, is a human journey. It’s about cultivating a mindset, processes, organization and culture that encourages constant innovation to meet ever-changing customer expectations and business goals. In this two-part blog series we’ll share seven guidelines for getting digital right. Read on for the first three.
