Secure Deployment of ABC_SrvAny: Configuration Checklist

Secure Deployment of ABC_SrvAny: Configuration Checklist

This checklist guides secure, production-ready deployment of ABC_SrvAny. It assumes a default installation; adjust paths, ports, and user names for your environment.

1. Pre-deployment preparation

• Inventory: Document servers, network zones, and dependencies (databases, auth services).
• Least privilege: Create a dedicated service account for ABC_SrvAny with only required permissions.
• Patch baseline: Ensure OS and dependent packages are fully patched.
• Backup plan: Verify backup/restore procedures for configuration and data.

2. Network and firewall

• Isolate network: Place ABC_SrvAny in a dedicated application subnet or VLAN.
• Allowlist ports: Open only the necessary ports (assume TCP 8080 for app, TCP 8443 for admin — adjust as needed).
• Restrict management access: Limit SSH/RDP and admin UI access to jump hosts or specific IP ranges.
• Internal segmentation: Block east-west access from untrusted zones to reduce lateral movement.

3. TLS and encryption

• TLS only: Serve all traffic over TLS 1.2+ (prefer TLS 1.3). Disable HTTP where possible and redirect to HTTPS.
• Certificates: Use certificates from a trusted CA or your internal PKI. Automate renewal (e.g., ACME).
• Strong ciphers: Configure server to prefer forward-secure ciphers (ECDHE, AES-GCM/ChaCha20).
• Encryption at rest: Enable disk- or file-level encryption for sensitive data and config files.

4. Authentication and authorization

• Central auth: Integrate with centralized identity (OIDC/SAML/LDAP) for operators and users.
• MFA: Enforce multi-factor authentication for all administrative accounts.
• Role-based access: Implement RBAC for service features and admin functions; follow least privilege.
• Service credentials: Store API keys and secrets in a secrets manager (not in plaintext on disk or repo).

5. Configuration management

• Immutable configs: Use version-controlled configuration (Git) and promote via CI/CD pipelines.
• Secrets handling: Use environment-specific secret stores (Vault, AWS Secrets Manager) with fine-grained access.
• Validate configs: Add automated config linting and unit tests in CI to prevent misconfiguration.

6. Hardening and runtime security

• Run as non-root: Execute ABC_SrvAny under an unprivileged user.
• Minimal runtime: Disable unused features, plugins, or modules to reduce attack surface.
• Process isolation: Use containers or VMs; apply namespaces and cgroups to limit resources.
• OS hardening: Enforce CIS or distro-specific benchmarks; disable unnecessary services.

7. Logging, monitoring, and alerting

• Structured logs: Emit structured logs (JSON) with consistent fields for correlation.
• Centralize logs: Forward logs to a secure logging system with retention and access controls.
• Metrics & traces: Expose application metrics and distributed traces; integrate with monitoring (Prometheus, Grafana).
• Alerting: Create alerts for high error rates, CPU/memory spikes, auth failures, cert expiry.

8. Auditing and compliance

• Audit trails: Enable detailed audit logging for configuration changes and administrative actions.
• Immutable storage: Store audit logs in write-once storage or append-only systems.
• Retention & review: Define log retention policies and schedule periodic review/audits.

9. Backup and disaster recovery

• Config backups: Regularly back up configurations and encryption keys; store offsite.
• Recovery drills: Run periodic restore tests to validate backups and runbooks.
• Failover: Design for high availability across zones/regions and test failover procedures.

10. CI/CD and automated deployments

• Pipeline security: Harden CI/CD (least privilege tokens, ephemeral runners).
• Canary rollouts: Use staged deployments with health checks and automatic rollback.
• Artifact signing: Sign build artifacts and verify signatures during deploy.

11. Dependency and supply-chain security

• Dependency scanning: Scan for vulnerable libraries and OS packages.
• SBOM: Maintain a Software Bill of Materials for ABC_SrvAny and its dependencies.
• Reproducible builds: Prefer reproducible build artifacts and verify checksums.

12. Incident response

• Playbooks: Prepare runbooks for common incidents (RCE, data exfiltration, key compromise).
• Forensics readiness: Enable detailed logging and preserve volatile data for investigations.
• Communication plan: Define internal/external notification templates and escalation paths.

13. Post-deployment verification

• Penetration test: Conduct an external or third-party pentest before production launch.
• Vulnerability scan: Run authenticated vulnerability scans regularly and remediate findings.
• Configuration audit: Use automated tools to verify security settings match your baseline.
