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 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 DeskVerify EC2 containment beyond a security group change
Swapping a compromised EC2 instance into an isolation security group stops new connections, not tracked ones. Learn which flows survive, how long idle timeouts let them run, and how to prove the cut happened.
Detection & response · Amazon Web Services · 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 DeskPlan Azure disaster recovery for a region without a pair
Thirteen Azure regions have no pair and eight more pair with a restricted-access region. This guide shows which built-in geo-redundancy disappears, what replaces it service by service, and how to choose the recovery region.
Resilience · Microsoft Azure · 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 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 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 DeskDesign health checks that remove broken instances without causing outages
A health check is an automated decision to remove capacity. Keep load balancer checks local, learn what your platform does when every target fails, and set probe timing from documented defaults.
Resilience · Amazon Web Services / Microsoft Azure / Google Cloud / Kubernetes · By Cloud Security DeskPlan for the backlog that follows a regional cloud outage
AWS fixed the DNS fault behind its October 2025 us-east-1 outage within three hours, yet recovery ran into the afternoon. Design retries, queues and capacity automation for that second phase.
Resilience · Amazon Web Services · 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.
Workload security · NIST / CISA / Office of Management and Budget / Amazon Web Services / Google Cloud / Microsoft Azure · By Cloud Security DeskRun code written by AI agents inside a disposable sandbox
Treat agent-generated code as untrusted input. Pick a microVM or user-space kernel boundary, keep egress and credentials off by default, and destroy the session when the user or conversation ends.
AI systems · Amazon Web Services / Microsoft Azure / Google Cloud / Firecracker / gVisor / OWASP · By Cloud Security DeskChoose a multi-region database consistency model before you need failover
The replication model decides which writes survive a Region failure. Compare asynchronous and quorum options in DynamoDB, Aurora, Spanner and Cosmos DB by recovery point, write latency and the reconciliation each one leaves you.
Resilience · Amazon Web Services / Google Cloud / Microsoft Azure · By Cloud Security DeskBack up a Kubernetes cluster so workloads can actually be restored
A Kubernetes backup has to carry definitions, Secrets and volume data, and the restore depends on identity, keys and images it never held. Plan the layers, the restore order and the checks that prove recovery.
Resilience · Kubernetes / Velero / Amazon Web Services / Google Cloud / Microsoft Azure · 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.

Remove internet-wide EC2 SSH rules after testing Session Manager or restricted SSH. Check all groups, IPv6, fresh sessions, and recovery access.
