Architecture controls for insider threats include data loss prevention policies on cloud storage, user and entity behavior analytics (UEBA) to detect anomalous access patterns, and separation of duties enforced through IAM policies that prevent any single user from both provisioning resources and modifying audit logs.
## What Are the 10 Key Elements of Effective Cloud Security Architecture?
### 1. Comprehensive Visibility [...] Misconfiguration is the leading cause of cloud data exposure. NIST SP 800-144 identifies misconfiguration of cloud platform settings as a primary risk in multi-tenant cloud deployments. Common misconfiguration patterns include publicly accessible S3 buckets, security groups allowing unrestricted inbound traffic on port 22 or 3389, IAM roles with wildcard permissions attached to internet-facing compute, and default credentials left unchanged on managed database services. [...] Data security architecture requires encrypting data at rest and in transit and managing encryption keys so that a compromise of the cloud provider does not automatically compromise the data. AWS Key Management Service, Azure Key Vault, and Google Cloud KMS each support customer-managed encryption keys (CMEK), which ensure the cloud provider cannot decrypt customer data without explicit authorization. NIST SP 800-111 provides the standard for encryption of stored data; NIST SP 800-52 Rev 2

The main cloud security architecture components and key elements in cloud security architecture are:
Identity and access management: Controls who gets access, how they authenticate, and what privileges they keep.
Network security: Segments traffic, reduces lateral movement, and protects cloud and hybrid connections.
Data encryption: Protects data at rest and in transit, with key management tied to risk.
Workload protection: Secures VMs, containers, serverless functions, and runtime behavior. [...] Cloud security architecture is the blueprint for protecting identities, workloads, data, networks, and control planes across cloud environments. It encompasses policies, trust boundaries, telemetry, and enforcement paths that govern cloud computing security under the shared responsibility model.
Organizations use it to reduce risk, support digital transformation, and make zero trust practical as the threat landscape shifts from perimeter defense to users, assets, and resources. [...] | SANS SEC549 | SEC549: Cloud Security Architecture focuses on designing secure, scalable cloud infrastructure through hands-on work in IAM, organization policy, network security, data security, and log aggregation. | Use it when the model is clear, but the implementation still feels fuzzy. |

As an example, consider the architecture below. An API gateway connects to a compute instance (ephemeral or persistent), which then accesses a persistent storage resource. Separately, there exists a server which can verify the authentication, authorization and/or identity of the caller. This is a generic representation of an OAuth, IAM or directory system, which controls access to these resources. Additionally, there exists an Ephemeral IAM server which controls access for the stored resources [...] ## Introduction¶
This cheat sheet will discuss common and necessary security patterns to follow when creating and reviewing cloud architectures. Each section will cover a specific security guideline or cloud design decision to consider. This sheet is written for a medium to large scale enterprise system, so additional overhead elements will be discussed, which may be unnecessary for smaller organizations.

### Secure Object Storage¶
Object storage usually has the following options for accessing data:
Accessing resources using built-in Identity and Access Management policies
Using cryptographically signed URLs and HTTP requests
Directly accessing with public storage
