24 publicationsFind 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 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 DeskRoll over a SAML signing certificate without an SSO outage
Replacing an identity provider's SAML signing key is a separate contract with every service provider. Classify each one by how it learns keys, overlap where it can hold two and finish by removing the old key everywhere.
Identity & access · Microsoft Entra / Okta / Google Workspace / Amazon Web Services · 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 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 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 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 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 DeskRemove public SSH access from an EC2 security group
Remove internet-wide EC2 SSH rules after testing Session Manager or restricted SSH. Check all groups, IPv6, fresh sessions, and recovery access.
Workload security · AWS · By Cloud Security DeskConnect to a Google Cloud VM with IAP and OS Login
Connect to a Linux VM through IAP and OS Login, check each permission and network layer, and remove old SSH paths with a tested recovery plan.
Identity & access · Google Cloud · By Cloud Security DeskRestrict SSH and RDP access with an Azure network security group
Inspect effective rules, preserve the approved management path and test a fresh connection.
Workload security · Azure · By Cloud Security DeskBind confidential GPU inference to a verified key release
Require composite evidence, owner policy and verified recipient binding before confidential inference receives protected key material.
AI systems · NVIDIA / Azure · By Cloud Security DeskGive Kubernetes admission webhooks an explicit failure contract
Treat an admission webhook as a control-plane dependency with explicit behavior for denial, call failure, mutation and the changes needed to repair it.
Workload security · Kubernetes · By Cloud Security DeskWorkload federation across clouds needs separate trust decisions
Cross-cloud federation adds trust decisions, not a portable permission system. Map each credential and resource grant before moving a runtime workload.
Identity & access · AWS / Google Cloud / Microsoft Entra · By Cloud Security DeskMake secret rotation reach every running application
Secret managers, mounted files, application memory and connection pools can disagree about the active credential. Test each stage before calling rotation complete.
Workload security · Kubernetes / AWS / Azure / Google Cloud · By Cloud Security DeskRotate Entra application certificates with proof of adoption
A renewed certificate can exist in Key Vault while a running client still uses the old key. Define the evidence that makes application rotation complete.
Identity & access · Microsoft Entra / Azure Key Vault · By Cloud Security DeskShort SSH certificates still need explicit access boundaries
An SSH certificate supplies bounded identity claims. The issuer, server, client and incident operator still make separate access decisions.
Identity & access · OpenSSH · By Cloud Security DeskCertificate renewal under shorter validity limits
Use the public TLS issuance schedule to review authorization, renewal, deployment and independent verification of the certificate an endpoint actually serves.
Resilience · CA/Browser Forum / Let's Encrypt / AWS · By Cloud Security DeskPrepare cloud workloads for hybrid post-quantum TLS
Hybrid support in a library is not proof that every TLS hop uses it. Verify negotiation, compatibility and fallback while keeping certificate authentication separate.
Workload security · IETF / NIST / OpenSSL / Cloudflare · By Cloud Security DeskReview the authority behind every Entra app consent
The permission name is only part of the decision. Review the access mode, resource scope, consenting authority and people who can change the application.
Identity & access · Microsoft Entra · By Cloud Security DeskMake regional failover work without new infrastructure
Prepare capacity, dependencies, and the routing control path before an incident, then measure when clients reach an accepted recovery service.
