Field notes
Change freezes feel safe. They also hide risk: delayed security patches, piled-up releases, and Friday-night catch-up deployments when the freeze finally lifts. Growing engineering organizations need a better bargain—safe change windows that reduce blast radius without…
Kubernetes Services that accept attacker-influenced external IPs—or LoadBalancer status updates from over-privileged identities—enable long-standing man-in-the-middle classes of risk inside clusters. Multi-tenant platforms amplify the issue. This article is operational hygiene guidance: inventory, admission, RBAC, and monitoring…
Mixed cloud estates are the default for growing engineering companies: a primary public cloud for product workloads, a second provider for resilience or acquisitions, a handful of SaaS platforms that hold customer data, and leftover on-prem…
Email remains the most successful fraud and malware transport for many organizations—not because filters are useless, but because identity, business processes, and DNS authentication are misaligned. SPF, DKIM, DMARC, and BIMI are necessary pieces of an…
Security tooling succeeds until cardinality and cost explode. Endpoint sensors, cloud trails, DNS logs, Kubernetes audit events, and WAF records grow faster than budgets. Without capacity planning, teams drop data silently, overrun SIEM spend, or drown…
GitOps made desired state reviewable—and turned Git into a high-value control plane. If attackers can merge to the path your controllers reconcile, they can ship workloads or retarget secrets. Protecting the desired state store is as…
Tabletop exercises fail when they become theater: a slide deck, a hypothetical so vague nobody sweats, and action items that die in a shared folder. They succeed when they are short, specific, and uncomfortable enough to…
Encrypting cloud virtual machine disks is table stakes—until you ask who holds the keys, who can export snapshots, and what happens when someone clones a volume into another project. Disk encryption at rest without key custody…
APIs are where modern products meet the internet—and where authorization bugs quietly become data breaches. A secure API is not a gateway plugin checklist. It is a baseline that covers authentication, authorization, and abuse controls as…
Most teams do not fail at dependency updates because they lack a bot. They fail because the bot becomes a firehose: dozens of pull requests a day, noisy CI failures, and a quiet cultural decision to…
