Chris Sistrunk and Stephanie Kiel outline fundamentals for resource-constrained utilities: asset inventory, credential hygiene, 3-2-1 backups, network segmentation, emergency planning aligned with FEMA NIMS, and third-party vendor access controls. It introduces Mandiant's 'Theory of 99,' noting 99% of OT-impacting intrusions occur on IT workstations/servers before reaching OT devices, positioning AI as a force multiplier for defenders. The roundup also links a State of AI Infrastructure report, Wiz research on cloud risk and AI infrastructure honeypots, a Rust supply chain attack on the arrayref crate tied to DPRK campaigns, and podcast episodes on AI-driven vulnerability patching and research. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Mandiant's Theory of 99 in OT security? It states that in intrusions deep enough to impact operational technology, 99% of compromised systems, malware, forensics work, and detection opportunities involve computer workstations and servers rather than the physical control devices themselves, with 99% of intrusion dwell time occurring in commercial off-the-shelf IT equipment before any Purdue level 0-1 devices are affected. This implies defenders can focus AI-driven monitoring on the IT layer to catch threats before they reach critical physical processes. _Teams building AI-augmented OT defenses can track threat research and analysis like this on daily.dev._ ### What basic security steps should water utilities take to protect PLCs from cyberattacks? Water utilities should inventory assets to find internet-exposed control systems, replace default credentials, harden firewalls, follow the 3-2-1 backup rule, apply network segmentation with multifactor authentication and read-only access where possible, integrate cyber-incident planning into existing FEMA NIMS and ICS4ICS response structures, and audit third-party vendor remote access with MFA and logging requirements. _Security teams hardening critical infrastructure can follow ongoing OT security guidance on daily.dev._ ### What Rust crate was recently hit by a supply chain attack linked to DPRK campaigns? Malicious versions of the arrayref Rust crate, along with other packages, executed a backdoor at compile time, and the attack infrastructure showed significant overlap with recent DPRK-linked supply chain attacks, including campaigns involving Mastra and axios. _Developers vetting Rust dependencies for supply chain risk can follow these disclosures on daily.dev._ ## Similar posts on daily.dev - [Cloud CISO Perspectives: Sticking to security fundamentals in the AI era](https://daily.dev/posts/cloud-ciso-perspectives-sticking-to-security-fundamentals-in-the-ai-era-tm4ld3t2e) · Google Cloud · 0 upvotes · 0 comments - [Cloud CISO Perspectives: How to build an AI-ready security program for the public sector](https://daily.dev/posts/cloud-ciso-perspectives-how-to-build-an-ai-ready-security-program-for-the-public-sector-w2duoyr0b) · Google Cloud · 0 upvotes · 0 comments - [Cloud CISO Perspectives: 2025 in review: Cloud security basics and evolving AI](https://daily.dev/posts/cloud-ciso-perspectives-2025-in-review-cloud-security-basics-and-evolving-ai-pju7utvav) · Google Cloud · 0 upvotes · 0 comments --- Tags: [#cyber](https://daily.dev/tags/cyber), [#ai-security](https://daily.dev/tags/ai-security) [View this post on daily.dev](https://daily.dev/posts/cloud-ciso-perspectives-tips-on-securing-the-water-sector-in-the-ai-era-knlcc0zbg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Cloud CISO Perspectives: Tips on securing the water sector in the AI era","url":"https://daily.dev/posts/cloud-ciso-perspectives-tips-on-securing-the-water-sector-in-the-ai-era-knlcc0zbg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/cloud-ciso-perspectives-tips-on-securing-the-water-sector-in-the-ai-era-knlcc0zbg"},"datePublished":"2026-08-31T16:02:00.094Z","dateModified":"2026-08-31T16:02:28.342Z","description":"Google Cloud's Cloud CISO Perspectives newsletter covers water sector cybersecurity, highlighting increased targeting of internet-connected PLCs at U.S. water...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/633b25c40b87604c4184aa5862083d4e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/633b25c40b87604c4184aa5862083d4e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Google Cloud","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Google Cloud","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/gcp","url":"https://daily.dev/sources/gcp"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/cloud-ciso-perspectives-tips-on-securing-the-water-sector-in-the-ai-era-knlcc0zbg","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"cyber,ai-security","timeRequired":"PT10M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Google Cloud","item":"https://daily.dev/sources/gcp"},{"@type":"ListItem","position":3,"name":"Cloud CISO Perspectives: Tips on securing the water sector in the AI era"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/cloud-ciso-perspectives-tips-on-securing-the-water-sector-in-the-ai-era-knlcc0zbg#faq","mainEntity":[{"@type":"Question","name":"What is Mandiant's Theory of 99 in OT security?","acceptedAnswer":{"@type":"Answer","text":"It states that in intrusions deep enough to impact operational technology, 99% of compromised systems, malware, forensics work, and detection opportunities involve computer workstations and servers rather than the physical control devices themselves, with 99% of intrusion dwell time occurring in commercial off-the-shelf IT equipment before any Purdue level 0-1 devices are affected.
