The Automotive industry’s inadequate approach towards software (in the cars)

Introduction The automotive industry has witnessed a paradigm shift with the increasing integration of software in vehicles. Modern cars are no longer just mechanical devices with a motor, wheels and steering; they are now sophisticated machines having dozens of CPUs (called ECU), entire computers, high speed network to connect them (called CAN-bus) and relying on complex highly distributed software systems. In my opinion, the industry fails to adapt to this new reality and fully embrace the concept of cars as hardware running software has significant consequences. This may sound contradictory at first, on one side they have these complex systems, on the other side they fail to adapt to this reality. In this article, I will explore how the automotive industry is not dealing correctly with this transformation and its potential implications.   Limited Focus on Software Development and Updates Traditionally, the automotive industry has primarily focused on hardware design and manufacturing, treating software as a necessary mean to make the hardware work. This approach results in a lack of emphasis on software development practices and updates capabilities. While cars are becoming more connected and dependent on software for various functionalities, manufacturers often overlook the importance of continuous software improvements…

ChatGPT and copywriting

I received a spam and the guy offered to have my corporate site re-written. He sent me an example of how it be like in a Google Docs document. The text was very artificial, kind of those written by ChatGPT (check my recent blog posts about this: I will write about this too.

So, he left the text there:…

ChatGPT and automotive cybersecurity #2/2: TISAX certification

This is the 2nd post about Automotive Cybersecurity. Since I am working these days on CSMS (based on ISO ECE 21434 and TISAX), part of my companies consulting offer for automotive I thought maybe I check what ChatGPT things about them.   First post was about CSMS and ISO 21434 and this one is about TISAX.   Query: Tell me about challenges in TISAX certification    ChatGPT: “TISAX (Trusted Information Security Assessment Exchange) is a security assessment and certification process for automotive suppliers. The certification is used to evaluate and ensure the information security capabilities of companies in the automotive sector. There are several challenges associated with TISAX certification: Complex requirements: TISAX has extensive and complex security requirements that can be difficult to understand and implement. Companies may struggle to meet these requirements and may need help from experts to achieve certification. Resource constraints: Implementing the security measures required for TISAX certification can be resource-intensive and time-consuming. This can be especially challenging for small or medium-sized businesses. Technical difficulties: Companies may face technical challenges in implementing the necessary security controls, particularly if their existing systems are not well-suited to the TISAX requirements. Cost: The cost of TISAX certification can be…

ChatGPT and automotive cybersecurity #1/2: About CSMS from ISO 21434

As promised, I played more with ChatGPT and this time I started to dig a bit into cybersecurity for automotive. Since I am working these days on CSMS (based on ISO ECE 21434 and TISAX), part of my companies consulting offer for automotive I thought maybe I check what ChatGPT things about them. Unfortunately, nothing dramatically new, a form of what a google search gives you. However, the model answered something interesting about TISAX, which usually I, as a human would probably answer.  ( No, this post is not written by ChatGPT: 🙂   )   Here it is:   Query: Tell me about CSMS from ISO 21434   ChatGPT: CSMS (Cybersecurity Management System) is a framework for managing cybersecurity within an organization, as defined in ISO 21434. ISO 21434 is an international standard for automotive cybersecurity that provides guidelines for the development and implementation of cybersecurity measures in the automotive sector. CSMS is designed to help organizations manage cybersecurity risks and protect against cyber threats. It is based on the same principles as other management systems, such as quality management or environmental management, and provides a structured approach to managing cybersecurity. The framework covers a range of cybersecurity-related activities, including:…

So much hype about Chat GPT… here are some facts

So much hype about ChatGPT these days.. But what does it mean? So, I gave it a try … and I created an account. This is the first post from many about ChatGPT. First thing you see when you go on the page:   CapabilitiesRemembers what user said earlier in the conversationAllows user to provide follow-up correctionsTrained to decline inappropriate requests LimitationsMay occasionally generate incorrect informationMay occasionally produce harmful instructions or biased contentLimited knowledge of world and events after 2021   I will only see later how true these warnings are 🙂     Query: What does Chat GPT mean? ChatGPT: “ChatGPT” stands for “Chat Generative Pretrained Transformer”. It’s a language model developed by OpenAI, which uses the Transformer architecture and is pre-trained on a large dataset to generate human-like text in response to prompts.     Nice, let’s try something else: If I ask about me or several people I know, but not any VIP person, nothing is found. If I ask about big VIPs, like Joe Biden, Olaf Scholz, Michael Jackson, then it finds various things you would find by just googling.. But then if I provide an anchor, a starting point, apparently this more information confuses the…

I am worried: AV-Comparatives tests of Business Security products

Av-Comparatives did a long-term test of security Business Products. The details can be seen here: Initially, I wanted to write about this test because I was surprised to see how well Microsoft Defender performed. But then, I started to read the details, even if the full report will only be released in December 2022.   Read below the things which surprised me:   Engines used Information about additional third-party engines/signatures used by some of the products: Acronis, Cisco, Cybereason, G Data, Trellix and VIPRE use the Bitdefender engine (in addition to their own protection features). VMware uses the Avira engine (in addition to their own protection features). G Data’s OutbreakShield is based on Cyren.   Of course, most of this is not new … What surprised me was: Cisco is using Bitdefender Watch Guard, Crowdstrike and K7 have own engines Crowdstrike’s ML engine is good G Data is using also Cyren    2) The special settings are not even close to the defaults. It is normal that in business environments, and with business products in general, to be configured by the system administrator, in accordance with vendor’s guidelines and their own expectations. But, this also tells me that there can be huge differences in the detection, performance and FP rate of…

(ISC)2 certification counts – how many CSSLP are out there?

(ISC)2 maintains this page with the counts of all certifications per country. I wrote before about this here, but this was back in 2013 (1.5 years after I became certified) !   Some statistics: As of September 25 2013: 1168 CSSLP  Romania  1 Germany 19   As of May 23 2022: 3008 CSSLP   Romania  6 Germany 48 Mexico 8       If these numbers appear big… look at the count of CISSP (without specializations): 152.623 as of today. So, yes, you can see how hard is to get this certification.   This year I celebrate 10 years of being a CSSLP!
