About A2A Secrets Integration

1. Overview

This article describes all supported methods for application-to-application credential delivery, rotation, and lifecycle management. These capabilities are natively embedded into the Segura platform and require no additional licensing.

2. Injection into Configuration Files

Segura automatically injects and updates secrets into configuration files across diverse environments, eliminating hardcoded credentials.

Supported File Formats

Injection Triggers

• Credential rotation event
• Scheduled interval
• On-demand API call
• Deployment hook (pre/post deploy)
• Webhook from external system

Delivery Modes

• Agentless via SSH (Linux/Unix) or WinRM (Windows) — no endpoint agent required
• Agent-based — for air-gapped, OT, or restricted environments

Additional Features

• Automatic rollback on injection failure
• JIT injection — secrets are never stored in code repositories
• Version control and atomic updates for configuration integrity
• Flexible templates with variable mapping, transformation rules, and conditional logic

API Reference

POST /api/v2/injection/config-file

3. Kubernetes Secrets Injection

Segura supports four delivery patterns for Kubernetes secret management, covering cloud-native, GitOps, and hybrid environments.

Delivery Pattern 1 — Native Kubernetes Secrets API

• Supports Opaque, TLS, Docker Config, ConfigMaps, and environment variables
• Multi-cluster and multi-namespace support
• Policy-driven pod restart on secret rotation
• RBAC and namespace policy enforcement

Delivery Pattern 2 — Secrets Store CSI Driver

• Memory-backed tmpfs volume mounting
• SecretProviderClass resource for declarative configuration
• JWT-based workload authentication
• Zero-downtime rotations where possible

Delivery Pattern 3 — Sidecar Injection

• Init container and sidecar patterns for secret delivery at pod startup
• Compatible with GKE, EKS, AKS, and OpenShift

Delivery Pattern 4 — External Secrets Operator (ESO)

• GitOps-compatible ExternalSecret and ClusterExternalSecret resources
• Synced from Segura vault to Kubernetes Secrets
• Argo CD and Flux integration
• ClusterSecretStore for multi-cluster secret federation

Authentication Methods

API Reference

POST /api/v2/injection/k8s-secret

4. Vault API — Fetching Credentials On Demand

Applications retrieve secrets on demand via the Segura REST API. All requests are logged for real-time monitoring, risk analytics, and compliance.

Authentication Methods

Dynamic Secrets

Dynamic secrets are ephemeral credentials generated on demand with an auto-revoke TTL, eliminating standing credentials.

• Database credentials (PostgreSQL, MySQL, MSSQL, Oracle)
• Cloud IAM roles (AWS, Azure, GCP)
• SSH certificates (signed, time-bound)
• API keys with scoped permissions

UEBA Integration

UEBA continuously monitors secret retrieval patterns. Anomalous access — such as unusual retrieval frequency, off-hours access, or access from unknown workloads — triggers SIEM alerts and optional automatic blocking.

API Reference

GET /api/v2/a2a/secrets/{id}
POST /api/v2/a2a/dynamic-secrets

5. Agent-Based AAPM

The Segura AAPM Agent is a lightweight agent for environments where direct vault connectivity is restricted — air-gapped networks, DMZs, OT environments, and isolated subnets.

Supported Platforms

Local Access Methods

• Local HTTP endpoint: http://localhost:8787/secret/{credential_id}
• CLI: segura-agent get-secret --id {credential_id}
• No network egress to vault required after agent registration

Key Features

• mTLS vault communication for secure agent-to-vault channel
• In-memory secret caching with configurable TTL
• Automatic rotation and renewal triggered by rotation events
• Offline/isolated mode with cryptographic integrity validation
• Event-driven rotation triggers: scheduled, on-demand, webhook

Example Usage

    # Bash
    SECRET=$(curl -s http://localhost:8787/secret/db_prod_password)
    
    # PowerShell
    $secret = Invoke-RestMethod -Uri "http://localhost:8787/secret/db_prod_password"

6. SDK & CLI Support

Segura provides native SDKs for eight programming languages and a full-featured CLI tool, enabling integration with virtually any application or automation workflow.

Native SDKs

All SDKs support: vault client, dynamic secrets, rotation callbacks, and cloud workload identity (AWS IRSA, Azure Managed Identity, GCP Workload Identity).

CLI Tool (segura-cli)

7. CI/CD Pipeline Integration

Segura integrates natively with major CI/CD platforms, enabling secure secret injection throughout build and deployment cycles without exposing credentials in pipeline configuration.

GitHub Actions Example (OIDC Federation)

    jobs:
      deploy:
        permissions:
          id-token: write
        steps:
          - uses: segura-security/action@v2
            with:
              vault-url: https://segura.company.com
              secrets: |
                db/prod/password > DB_PASSWORD
                api/stripe/key   > STRIPE_KEY

Policy Enforcement

• Block deployments with outdated or exposed secrets
• Dynamic provisioning and usage tracking of build-time secrets
• All pipeline secret access logged and auditable

8. GitOps Integration

Segura integrates with GitOps toolchains, enabling secret synchronization directly into Kubernetes clusters without storing secrets in Git repositories.

Argo CD

• Native Argo CD plugin for vault-backed secret injection

• Rotation-triggered sync — Argo CD re-syncs automatically when Segura rotates a secret

• Compatible with Application and ApplicationSet resources

Flux + External Secrets Operator

• Flux integration via External Secrets Operator (ESO)
• SecretStore and ClusterSecretStore resources for Segura vault backend
• ExternalSecret and ClusterExternalSecret for cross-namespace and multi-cluster federation

ExternalSecret Example

    apiVersion: external-secrets.io/v1beta1
    kind: ExternalSecret
    metadata:
      name: db-credentials
    spec:
      secretStoreRef:
        name: segura-vault
        kind: ClusterSecretStore
      target:
        name: db-credentials
      data:
        - secretKey: password
          remoteRef:
            key: db/prod/password

9. Workload Identity & SPIFFE/SPIRE

Segura supports the SPIFFE (Secure Production Identity Framework for Everyone) standard, enabling zero-static-credentials workload identity for modern microservices architectures.

SPIFFE/SPIRE Support

• JWT-SVID — JSON Web Token SVID for API-based secret retrieval
• X.509-SVID — certificate-based identity for mTLS communication
• Zero-static-credentials pattern — workloads authenticate via identity, not stored secrets
• Compatible with Istio, Envoy, and Linkerd service meshes

Cloud Workload Identity Federation

10. AI Agent & NHI Support

Segura provides credential governance for non-human identities (NHI) — including AI agents, RPA bots, serverless functions, and microservices — with the same security controls applied to human privileged access.

Supported NHI Types

Governance Features

• Scoped access — each NHI is granted only the secrets required for its task
• Ephemeral credentials — short-lived credentials auto-expire after use or TTL
• UEBA behavioral monitoring — baselines normal NHI access patterns and alerts on deviations
• Automated lifecycle management — provisioning, rotation, and revocation without manual intervention
• Full auditability — all NHI credential issuance, use, and revocation is logged with context

11. SIEM/SOAR Integration

All A2A secret access events are exported to SIEM and SOAR platforms for centralized monitoring, threat detection, and automated response.

Integration Methods

Automated SOAR Playbook Scenarios

• Anomaly detection — NHI or user retrieves secret outside normal pattern
• Access-outside-window — secret accessed outside approved time window
• NHI compromise — behavioral deviation triggers credential revocation and incident
• Excessive retrieval — secret queried above threshold, triggering investigation
• Unknown workload — unregistered identity attempts secret retrieval

Example Syslog Event

    CEF:0|Segura|PAM|4.0|A2A\_SECRET\_ACCESS|Secret retrieved by NHI|5|
      src=10.0.1.45 suser=svc\_rpa\_bot dst=segura-vault
      cs1=db/prod/password cs1Label=SecretPath
      cs2=ANOMALY cs2Label=RiskLevel
      msg=Access outside baseline window
