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 Entra token protection without breaking unsupported clients
Token protection makes Entra ID refuse token requests that a device-bound session does not back. Scope it to supported apps and platforms, triage report-only data by code and platform, and cover what stays unbound.
Identity & access · Microsoft Entra / Microsoft Intune / Microsoft Graph · By Cloud Security DeskInvestigate a SaaS integration breach through its OAuth tokens
A vendor that stores OAuth tokens for your SaaS tenants has been breached. Confirm from your own logs what the tokens did, revoke them on every platform, and search the exposed records for secrets.
Detection & response · Salesforce / Google Workspace / Microsoft Entra ID · By Cloud Security DeskInvestigate stolen cloud credentials used to run AI models
When stolen keys run foundation models in your account, the evidence is split between CloudTrail, usage logs that may never have been enabled and a bill that lags by a day or more.
Detection & response · Amazon Web Services / Microsoft Azure / Google Cloud · 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 DeskFind the AWS global control planes in your recovery path
Thirteen AWS control planes run in us-east-1 or us-west-2, and ordinary calls from other Regions still reach them. Audit runbooks, SDK settings and the last exercise, then swap each dependency for a data-plane operation.
Resilience · Amazon Web Services · By Cloud Security DeskLock down self-hosted model servers before exposing them
Built-in credentials in vLLM, SGLang and Triton cover less than their names suggest, Ollama's local API has none, and vLLM and SGLang leave their internal planes unauthenticated. Here is what stays open and what must sit in front.
AI systems · vLLM / SGLang / Ollama / NVIDIA Triton Inference Server / Kubernetes / nginx · 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 DeskFind the Entra changes that Backup and Recovery cannot roll back
Microsoft Entra Backup and Recovery rolls listed properties back to a daily backup kept for seven days. Credentials, role assignments, owners and user consent stay in place, and an unscoped recovery can undo your own containment.
Resilience · Microsoft Entra / Microsoft Graph · By Cloud Security DeskGive a SaaS vendor an AWS role without creating a confused deputy
A vendor's cross-account role is safe only if your trust policy demands an exact external ID, the vendor's backend generates and enforces it per tenant, and your reviews catch drift and offboard the role.
Identity & access · 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.
Identity & access · Amazon Web Services / Microsoft Azure / Microsoft Entra / Google Cloud · By Cloud Security DeskSeparate API gateway JWT checks from backend authorization
A gateway that accepts a JWT has checked its signature, issuer, audience and time window. It has not checked token type, revocation, cached decisions or object ownership. This mapping shows which side owns each decision.
Workload security · Amazon Web Services / Microsoft Azure / Google Cloud · 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 DeskMap the OWASP Top 10 for Agentic Applications to cloud controls
Each OWASP agentic risk mapped to the controls AWS, Microsoft and Google document for their agent platforms, with a plain account of which risks no infrastructure setting can close.
AI systems · OWASP GenAI Security Project / Amazon Web Services / Microsoft Azure / Google Cloud · By Cloud Security DeskGive Kubernetes pods cloud credentials without static keys
EKS Pod Identity, IRSA, AKS Workload ID and Workload Identity Federation for GKE all swap a projected token for short-lived credentials. What leaks if you stop there is the node's own identity.
Identity & access · Amazon Web Services / Microsoft Azure / Google Cloud / Kubernetes · By Cloud Security DeskPrepare Azure automation for mandatory MFA on resource management
Azure now requires MFA for user accounts that write through Resource Manager. Find the scripts and pipelines that still sign in as people and move each one to a managed identity or federated credential.
Identity & access · Microsoft Azure / Microsoft Entra / GitHub / Azure DevOps / HashiCorp Terraform · By Cloud Security DeskMove cloud logs to cheaper tiers without losing detection coverage
CloudWatch Infrequent Access, the Sentinel data lake and Cloud Logging exclusions all cut ingestion cost by removing real-time detection hooks. Place each source by the rules that read it, then prove the replacements fire.
Detection & response · AWS / Microsoft Azure / Google Cloud · By Cloud Security DeskPublish npm packages with trusted publishing instead of long-lived tokens
npm revoked classic tokens and capped write tokens at 90 days. Move CI releases to trusted publishing with staged approval, then protect the workflow, tags and environment that now hold publish authority.
Workload security · npm / GitHub / GitLab / CircleCI / Sigstore · By Cloud Security DeskBuild an inventory of non-human identities across cloud accounts
Find every service account, service principal, role and key across AWS, Entra and Google Cloud, then record the owner, credential type, privilege and last use that turn a list into decisions.
Identity & access · Amazon Web Services / Microsoft Entra / Microsoft Azure / Google Cloud / OWASP · 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.
Workload security · Kubernetes / Amazon EKS / AWS KMS / Azure Kubernetes Service / Azure Key Vault / Google Kubernetes Engine / Cloud KMS · By Cloud Security DeskNormalize cloud security logs with OCSF before writing detections
OCSF puts CloudTrail, Azure Activity Log and Google audit records into the same API Activity fields. Detections still depend on the mapping, the schema version and provider semantics that normalization does not erase.
Detection & response · Open Cybersecurity Schema Framework / 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.
