Part 1 explained how we have to bound behavior instead of asserting exact outputs. This post maps where to place those boundaries. AI systems expose attack surfaces at three runtime checkpoints (i.e., input, processing and output) and the checks differ by system type (classical ML, LLM-based, or hybrid).
This is the first of five posts on testing AI systems securely. If you've shipped or evaluated AI in production, you've probably felt it: the test suite passes, coverage looks good, and something still nags. *What are we actually validating?* That gap is what this series addresses.
In today's rapidly evolving industrial landscape, securing Operational Technology (OT) is more critical than ever due to increased connectivity and sophisticated cyber threats. Throughout this blog post series, we will dive into the world of Operational Technology Security. This edition of the series focuses on how Red Team assessments can assist companies in identifying and … Continue reading Attack and Defense in OT: Enhancing Cyber Resilience in Industrial Systems with Red Team Operations
A brief look at the updated TIBER-EU framework with DORA TLPT coming into play. In our previous post, we have discussed the “transition” from TIBER to TLPT (Threat-Led Penetration Testing), highlighting some differences between the previous TIBER specification and the requirements as indicated by DORA. This is mostly just a change in terminology. We concluded … Continue reading What’s new for TIBER-EU?
Many enterprise laptops use BitLocker to provide full disk encryption (FDE) to protect sensitive data from exposure if the laptop were stolen. But how adequate is the default implementation of BitLocker to protect data at rest in this scenario? The security of all encryption relies on protection of the key material. A common assumption is … Continue reading Wake up and Smell the BitLocker Keys
Introduction In our previous post, we published an analysis of current TIBER implementations ahead of DORA's TLPT requirements. To recap, this contained: An overview of existing TIBER implementations (situation mid-2024) A comparison of the respective guidance documents w.r.t. major building blocks, such as the generic threat landscape, purple teaming, leg-ups, scenario X Assurance that consistency … Continue reading TLPT & ME: Everything you need to know about Threat-Led Penetration Testing (TLPT) in a TIBER world.
