61 publicationsTreat a cloud model retirement as a security change
Bedrock and Agent Platform fail closed on a model's retirement date, while Foundry can swap a different model in behind the same deployment name. Read the three calendars, compare the replacement's controls and decide per deployment.
AI systems · Amazon Web Services / Microsoft Azure / Google Cloud · By Cloud Security DeskAdmit MCP servers before agents can call their tools
An MCP server's tool descriptions can change after approval with no new release. Record provenance and execution context, hash the definitions per authorization context, enforce the pin at a gateway or allowlist, and watch for drift.
AI systems · MCP / AWS / Anthropic / GitHub / Microsoft Azure / Google Cloud / OWASP · By Cloud Security DeskRoll out configuration changes as carefully as code
Flags, policy rows, generated files and customer settings triggered several global outages between 2024 and 2026. Seven primary incident reports show how each change slipped past its safeguards, and which controls their authors adopted afterward.
Resilience · Amazon Web Services / Microsoft Azure / Google Cloud / Cloudflare / CrowdStrike · By Cloud Security DeskTier Entra administrator roles by the control they can take
Microsoft's own password reset and sensitive action tables show which Entra roles can take over which accounts. Use them, plus the non-role paths, to set three tiers, assignment rules and the controls that keep lower tiers out.
Identity & access · Microsoft Entra / Microsoft Graph · By Cloud Security DeskFind the Kubernetes RBAC permissions that lead to cluster admin
Group RBAC grants by what they yield, not by verb. Then close the nodes/proxy exec path with v1.36 fine-grained kubelet permissions, narrow impersonation, and prove each removal with a negative test.
Identity & access · Kubernetes / Amazon Web Services / Google Cloud / Microsoft Azure · By Cloud Security DeskKnow what service mesh mTLS proves about the caller
A mesh handshake proves that a peer held a key for a namespace and service account. It says nothing about the user or the operation, and permissive defaults, probes and waypoints open paths around it.
Workload security · Istio / Linkerd / Kubernetes / Google Cloud / Microsoft Azure / Amazon Web Services · By Cloud Security DeskTune managed WAF rules without opening a bypass
Fix a managed WAF false positive by changing one rule for one route, then decide what happens to the request body bytes AWS WAF, Azure WAF and Cloud Armor never inspect.
Workload security · Amazon Web Services / Microsoft Azure / Google Cloud · By Cloud Security DeskPlan for an outage at your CDN or edge provider
When the CDN, WAF and edge provider fails, traffic can move to a regional WAF, a second CDN or the origin, and each keeps less protection. Decide early whether a second path is worth securing.
Resilience · Microsoft Azure / Cloudflare / Amazon Web Services / Google Cloud · By Cloud Security DeskUse DNS egress filtering without mistaking it for a firewall
Resolver-layer filters in AWS, Azure and Google Cloud decide which names a workload can resolve, not where it connects. What each provider says its DNS control misses, and the connection control to pair with it.
Workload security · Amazon Web Services / Microsoft Azure / Google Cloud · By Cloud Security DeskKeep semantic response caches inside authorization scope
A semantic cache returns whatever its nearest stored prompt earned. Put tenant, user or entitlement scope, template and model into an exact-match partition, close the write path, and treat thresholds as a correctness setting.
AI systems · Microsoft Azure / Google Cloud / Redis / GPTCache / Amazon Web Services · By Cloud Security DeskCompare just-in-time privileged access in AWS, Azure and Google Cloud
Entra PIM and Google Cloud PAM make roles temporary natively, while AWS relies on TEAM or partner tools. All three end elevation by removing an assignment, and sessions, caches and minted tokens can keep running.

Row-level security only filters queries from roles that do not bypass it. Test with the production login role, through the production pooler, with transaction-local tenant context and a patched minor release.
Workload security · PostgreSQL / PgBouncer / Amazon Web Services / Microsoft Azure / Google Cloud / Supabase · By Cloud Security DeskPlan the move from ingress-nginx to Gateway API
Ingress-nginx is archived and will not be patched again. Contain the old controller, inventory the behaviors your clients depend on, and cut over to Gateway API with evidence and a rollback path.
Workload security · Kubernetes / Google Cloud / AWS / Azure · By Cloud Security DeskDesign AI agents that contain indirect prompt injection
Filters lower the odds that an agent obeys injected text. Architecture decides what an obeying agent can reach. Compare six published patterns and CaMeL by what each removes, what it costs and what it still misses.
AI systems · Google DeepMind / AgentDojo / NIST / OWASP / Microsoft · By Cloud Security DeskContain failures with cell-based architecture and shuffle sharding
Cells limit a failure to the tenants behind one partition only when routing, data and change delivery are partitioned too. Here is how to choose the key, size cells and check the shuffle-sharding arithmetic.
Resilience · AWS / Microsoft Azure / Slack · By Cloud Security DeskStop S3 ransomware that encrypts objects with customer-provided keys
SSE-C ransomware rewrites S3 objects under a key only the attacker holds. AWS now blocks SSE-C by default on most buckets; this guide covers what that default misses and the controls that close the gap.
Detection & response · Amazon Web Services · By Cloud Security DeskEncrypt Kubernetes Secrets at rest with a KMS v2 provider
KMS v2 keeps etcd copies and backups unreadable without an external key, but it does not stop API readers. Configure it, compare what EKS, AKS and GKE already do, and finish key rotations with a rewrite.

Bedrock Guardrails, Azure Prompt Shields and Google Cloud Model Armor all score text for injected instructions. They differ in which content reaches the classifier, how you mark it, and what each one skips.
AI systems · Amazon Web Services / Microsoft Azure / Google Cloud · By Cloud Security DeskBuild a cryptographic inventory for the post-quantum transition
Record where public-key cryptography protects long-lived data and which library, service or vendor must change it. Then rank entries by function and data lifetime, not by how many RSA keys a scanner found.

The Digital Omnibus moved high-risk AI duties to December 2027 and August 2028, but prohibitions, AI literacy and Article 50 transparency already apply. See which dates moved and what cloud teams should build now.
AI systems · European Union / European Commission · By Cloud Security DeskPrepare a cloud exit strategy that satisfies DORA
DORA requires a tested exit plan for every cloud service that supports a critical or important function. This guide turns that duty into dependency maps, measured data exports, staged tests and register entries that agree.
