**What it does.** Deploy cloud-native deception across AWS, Azure, and GCP using decoy (honey) resources whose only purpose is to generate a high-fidelity alert the instant an attacker touches them: canary IAM access keys, permission-less decoy users/roles/service principals, honey object-storage buckets, and decoy secrets in Secrets Manager / Key Vault / Secret Manager. Wires detection through CloudTrail + EventBridge, Azure Sentinel honeytoken watchlists + Defender, and GCP Cloud Audit Logs, so any use of a decoy is routed to the SOC with near-zero false positives. Use when protecting cloud accounts and data stores, when an org has only on-prem honeypots and needs cloud coverage, when seeding fake AWS keys to catch credential theft and code-leak exposure, or when detecting cloud reconnaissance and lateral movement. Keywords: cloud deception, canary token AWS, honey S3 bucket, decoy IAM credentials, CloudTrail alert, GuardDuty, Sentinel honeytoken, decoy secret, honey service account, cloud honeypot, breach detection.

# Deploying Cloud Deception with Decoy Resources

## When to Use

- When cloud accounts (AWS/Azure/GCP) hold crown-jewel data or infrastructure and you need a tripwire that fires the moment an attacker who has gained access starts to operate.
- When the only deception in place is on-prem honeypots, leaving the cloud control plane uninstrumented.
- When seeding fake credentials to catch credential theft, accidental code-repo leaks, or secrets exposed in build pipelines.
- When detecting cloud reconnaissance (enumeration of IAM, storage, or secrets) and lateral movement that legitimate users would never perform.
- When you want detections that survive into incident response with strong fidelity — a touch on a decoy resource almost always means malicious or unauthorized activity.

This is the cloud counterpart to on-prem honeypot/honeytoken/canary-token deployment skills. For program strategy and how these Activities map to adversary engagement goals, use `designing-adversary-engagement-with-mitre-engage`.

## Prerequisites

- Cloud admin/IAM permissions to create decoy principals, storage, secrets, and detection wiring, ideally in a dedicated deployment role with least privilege.
- Cloud audit logging already enabled: **AWS CloudTrail** (multi-region, with management and relevant data events), **Azure Activity log + Microsoft Entra audit/sign-in logs**, **GCP Cloud Audit Logs (Admin Activity always on; Data Access enabled where needed)**.
- A SIEM/alert sink: SNS topic, Microsoft Sentinel workspace, or GCP Pub/Sub + Monitoring, with routing to the SOC.
- A naming and tagging convention that is plausible to an attacker but unambiguous to defenders internally (e.g., realistic names, plus an internal `deception=true` tag/label kept out of attacker-visible metadata).
- **Decoy principals must be permission-less (explicit deny-all).** The value is the alert, never the access. A decoy that grants real privilege is a liability, not a control.

## Workflow

### 1. Decide what to mimic
Pick decoys that match how *your* attackers operate: leaked AWS keys (credential theft), an "admin" S3 bucket (data discovery), a `prod-db-password` secret (secrets harvesting), a privileged-looking service account (cloud lateral movement). Place credential decoys where harvesting tools look: env files, CI variables, code comments, an internal wiki.

### 2A. AWS — canary access keys on a permission-less user
Create a decoy IAM user with an explicit deny-all policy, then issue an access key to plant:
```bash
aws iam create-user --user-name svc-backup-prod --tags Key=deception,Value=true
aws iam put-user-policy --user-name svc-backup-prod \
  --policy-name deny-all \
  --policy-document '{"Version":"2012-10-17","Statement":[{"Effect":"Deny","Action":"*","Resource":"*"}]}'
aws iam create-access-key --user-name svc-backup-prod   # plant the returned AccessKeyId/Secret
```
Any use of this key appears in CloudTrail (even denied calls, which still log `AccessDenied`). Wire an EventBridge rule on CloudTrail to alert:
```bash
aws events put-rule --name decoy-key-used \
  --event-pattern '{"detail":{"userIdentity":{"userName":["svc-backup-prod"]}}}'
aws events put-targets --rule decoy-key-used \
  --targets "Id"="1","Arn"="arn:aws:sns:us-east-1:111111111111:soc-deception-alerts"
```

### 2B. AWS — honey S3 bucket
Create a believable bucket, enable object-level data events, and alert on any read/list:
```bash
aws s3api create-bucket --bucket acme-prod-db-backups-2026 --region us-east-1
aws s3api put-bucket-tagging --bucket acme-prod-db-backups-2026 \
  --tagging 'TagSet=[{Key=deception,Value=true}]'
# Ensure CloudTrail captures S3 data events for this bucket, then alert on GetObject/ListBucket
aws events put-rule --name decoy-bucket-access \
  --event-pattern '{"detail":{"eventSource":["s3.amazonaws.com"],"requestParameters":{"bucketName":["acme-prod-db-backups-2026"]}}}'
```

### 2C. AWS — decoy secret
```bash
aws secretsmanager create-secret --name prod/db/master-password \
  --secret-string '{"username":"dbadmin","password":"DECOY-DO-NOT-USE"}' \
  --tags Key=deception,Value=true
# Alert on GetSecretValue for this secret via EventBridge -> SNS
```

### 3A. Azure — honeytoken watchlist + decoy service principal
Microsoft Sentinel natively supports honeytokens via a **Watchlist** of the `HoneyTokens` template; tagged decoy accounts/secrets raise analytics alerts on use. Create a permission-less decoy app registration / service principal, then add its identifiers to the HoneyTokens watchlist and enable the related analytics rules. Microsoft Defender for Cloud and Entra ID Protection surface anomalous sign-ins to the decoy identity.

### 3B. Azure — honey storage + Key Vault decoy secret
Create a decoy Storage account and Key Vault, enable diagnostic logging to the Sentinel workspace, store a decoy secret, and write an analytics rule that fires on any data-plane read of the decoy resources.

### 4A. GCP — decoy service account + honey GCS bucket
Create a service account with no role bindings (permission-less), generate a key to plant, and alert on its use via Cloud Audit Logs:
```bash
gcloud iam service-accounts create svc-billing-export \
  --display-name="billing-export"
gcloud iam service-accounts keys create decoy-key.json \
  --iam-account=svc-billing-export@PROJECT.iam.gserviceaccount.com   # plant this key
gsutil mb -b on gs://acme-finance-exports-2026
```
Create a log-based metric + alerting policy in Cloud Monitoring that triggers on any audit-log entry where the principal is the decoy service account or the resource is the honey bucket.

### 5. Centralize and de-duplicate
Route all clouds' decoy alerts to one SOC pipeline. Tag each alert as DECEPTION/high-fidelity so it bypasses normal noise filtering and triggers an IR playbook rather than a triage queue.

### 6. Validate (red-team the decoys)
Have an authorized tester use each decoy (read the bucket, call with the key, fetch the secret) and confirm an alert lands end-to-end within target latency. A decoy you have not tested is assumed broken.

### 7. Maintain realism and rotate
Refresh decoy names, secrets, and pocket-litter periodically so they age with the real environment. Track every decoy in an inventory so they are never mistaken for real assets during audits or cleanups.

## Key Concepts

| Concept | Definition |
|---|---|
| Decoy / honey resource | A cloud object created solely to be touched by an attacker; no legitimate user has any reason to use it. |
| Canary access key | A planted credential whose use generates an audit-log event; carries deny-all permissions. |
| High-fidelity alert | A near-zero-false-positive signal because legitimate workflows never reference the decoy. |
| Permission-less principal | A decoy IAM user/role/service principal/service account with explicit deny-all or no role bindings. |
| Data event | Cloud audit logging of object/data-plane access (e.g., S3 GetObject), required to detect storage decoys. |
| Pocket litter | Plausible supporting artifacts (fake configs, env files, wiki entries) that make a decoy credible. |
| Decoy inventory | The authoritative internal record distinguishing decoys from real assets. |

## Tools & Systems

- **AWS** — IAM (decoy users/roles), S3 (honey buckets, data events), Secrets Manager / SSM Parameter Store (decoy secrets), CloudTrail, EventBridge, SNS/Lambda, GuardDuty (correlate anomalous use).
- **Azure** — Microsoft Entra ID (decoy app registrations / service principals), Storage / Key Vault decoys, **Microsoft Sentinel HoneyTokens watchlist** and analytics rules, Microsoft Defender for Cloud, Entra ID Protection.
- **GCP** — IAM service accounts (decoys), Cloud Storage (honey buckets), Secret Manager (decoy secrets), Cloud Audit Logs, log-based metrics + Cloud Monitoring alerting, Pub/Sub.
- **Open-source / managed honeytoken systems** — Canarytokens (https://canarytokens.org offers AWS API key tokens), Thinkst Canary, SpaceSiren / SpaceCrab (self-hosted AWS honey-token frameworks).
- **SIEM/SOAR** — to centralize alerts across clouds and drive an IR playbook on any decoy hit.

## Common Scenarios

- **Credential-theft / code-leak detection.** Plant a canary AWS key in CI variables, an env file, and a private repo. Any external use (even from a leaked public push) fires within minutes.
- **Crown-jewel data store.** Stand up a honey "backups" bucket next to the real one; attackers enumerating storage hit the decoy first and reveal themselves.
- **Cloud lateral movement.** A permission-less decoy service principal that "looks" privileged catches adversaries assuming roles during pivoting.
- **Secrets harvesting.** Decoy entries in Secrets Manager / Key Vault / Secret Manager detect tools scraping the secrets store.
- **Migrating from on-prem-only deception.** Mirror the existing on-prem decoy strategy into the cloud control plane so coverage follows workloads.

## Output Format

Produce a **Cloud Deception Deployment Record** using `assets/template.md`, containing:

1. **Decoy inventory** — per decoy: cloud, type, plausible name, real placement location of any planted credential, internal `deception` tag/label, owner.
2. **Detection wiring** — per decoy: audit-log source → rule/pattern → alert sink → IR playbook reference, with the target alert latency.
3. **Least-privilege proof** — evidence each decoy principal is deny-all / no-role-binding.
4. **Validation results** — date tested, who tested, end-to-end latency observed, pass/fail.
5. **Maintenance plan** — rotation cadence and review owner.

Use `scripts/process.py` to render the deployment record and a per-decoy detection checklist from a decoy-inventory JSON, and to flag decoys missing detection wiring or validation.

## 2. Least-privilege proof
- AWS decoy users: explicit `Deny *` inline policy attached (`deny-all`); verified with `aws iam get-user-policy`.
- Azure decoy SP: zero role assignments; verified in Entra.
- GCP decoy SA: zero IAM policy bindings; verified with `gcloud iam service-accounts get-iam-policy`.

## 3. Validation results (red-team each decoy)
| Decoy | Tested | By | Observed latency | Pass/Fail |
|---|---|---|---|---|
| svc-backup-prod | 2026-05-20 | Red team | 90 s | PASS |
| acme-prod-db-backups-2026 | 2026-05-20 | Red team | 2 min | PASS |
| prod/db/master-password | 2026-05-20 | Red team | 75 s | PASS |
| Azure honeytoken SP | 2026-05-20 | Red team | 6 min | PASS |
| svc-billing-export | 2026-05-20 | Red team | 4 min | PASS |

## 4. Maintenance plan
- **Rotation cadence:** Refresh names/secrets/pocket-litter quarterly so decoys age with prod.
- **Review owner:** [Cloud security lead], quarterly.
- **Inventory rule:** No decoy is deleted during clean-ups/audits without confirming against this record.

# Cloud Deception — Standards & Reference

## Detection foundations (audit logging is mandatory)
Cloud deception only works if a decoy touch is logged. Confirm these before deploying.

### AWS
- **CloudTrail** — management events plus **data events** (S3 object-level, Lambda invoke, etc.) for any storage/secret decoys. Multi-region trail recommended.
- **EventBridge** — pattern-match CloudTrail events on `userIdentity.userName`, `eventSource`, or `requestParameters.bucketName` and target SNS/Lambda.
- **GuardDuty** — correlates anomalous credential/API behavior; useful to enrich a decoy hit.
- Note: even *denied* API calls by a deny-all decoy principal are recorded in CloudTrail as `AccessDenied`, so the alert fires regardless of granted permission.

### Azure / Microsoft
- **Azure Activity log** + **Microsoft Entra ID audit and sign-in logs** streamed to a Log Analytics / Microsoft Sentinel workspace.
- **Microsoft Sentinel HoneyTokens** — built-in watchlist template; decoy identifiers added to the watchlist drive analytics rules that alert on use.
- **Microsoft Defender for Cloud** and **Entra ID Protection** — surface anomalous access to decoy identities.
- Enable diagnostic settings on decoy Storage accounts and Key Vaults to capture data-plane reads.

### GCP
- **Cloud Audit Logs** — Admin Activity logs are always on; enable **Data Access** logs for the services hosting decoys (Cloud Storage, Secret Manager, IAM).
- **Log-based metrics + Cloud Monitoring alerting policies** — trigger on audit entries where `protoPayload.authenticationInfo.principalEmail` is the decoy service account or the resource is the honey bucket.
- **Pub/Sub** sink to forward to a SIEM.

## Operating principles
- **Deny-all decoys only.** Decoy principals must carry an explicit deny-all policy (AWS) or no role bindings (GCP) / no privileged roles (Azure). The control's value is the alert, never access.
- **Keep an internal decoy inventory** separate from attacker-visible metadata so audits and clean-ups never delete a tripwire by accident, and real assets are never mistaken for decoys.
- **Validate end-to-end** (red-team each decoy) and record observed alert latency. Untested decoys are assumed non-functional.
- **Mark deception alerts high-fidelity** so they bypass routine noise filtering and go straight to an IR playbook.
