System Input Control Policies and Procedures
| Version | 1.0 |
| Effective Date | April 2026 |
| Review Cycle | Annual |
| Document Owner | Chief Information Security Officer (CISO) |
| Classification | CONFIDENTIAL — Internal Use Only |
| Applicable Standard | SOC 2 Type II |
1. Purpose
This document defines the policies and procedures governing how data inputs are controlled, validated, and managed within DCKAP Integrator. These controls ensure that all data entering the platform — whether from eCommerce systems, ERP APIs, or customer configuration — is complete, accurate, and authorised.
2. Scope of Input Controls
- API payloads received from source systems (eCommerce, ERP, WMS, etc.).
- Customer-entered configuration data via the DCKAP Integrator portal.
- Webhook and event-driven data ingested in real time.
- Bulk import files uploaded for batch processing.
- System-to-system authentication inputs (API keys, OAuth tokens).
3. Input Control Policies
3.1 Authorisation Policy
All data inputs must originate from authenticated and authorised source systems or users. Unauthenticated inputs are rejected at the API gateway before reaching the processing engine.
- All API connectors require valid credentials stored in the DCKAP credential vault.
- Portal inputs require the user to be authenticated via SSO/MFA.
- Inputs from unknown IP ranges are flagged and can be blocked by configuration.
3.2 Input Completeness Policy
Inputs must contain all mandatory fields defined by the integration schema before processing is initiated.
- Missing mandatory fields trigger immediate rejection with a structured error response.
- Partial payloads that cannot be completed via enrichment are quarantined.
- Incomplete inputs are logged with the missing field list for audit purposes.
3.3 Input Accuracy Policy
Field values must conform to defined data types, formats, and permissible value ranges.
- Type mismatches (e.g., text in a numeric field) are rejected.
- Out-of-range values trigger configurable reject or default-value substitution.
- Date and currency formats are normalised to ISO standards before processing.
4. Input Control Procedures
| Control | Procedure | Owner |
|---|---|---|
| Authentication Check | Validate API key / OAuth token against credential vault on every request | API Gateway |
| Schema Validation | Validate payload against registered JSON/XML schema for the connector | Integration Engine |
| Field Type Check | Reject fields with incorrect data types per field definition | Validation Layer |
| Mandatory Field Check | Reject payload if any mandatory field is absent or null | Validation Layer |
| Range Check | Reject or flag numeric and date values outside configured bounds | Validation Layer |
| Duplicate Detection | Identify and skip duplicate records using unique record key | Deduplication Service |
| Injection Prevention | Strip script tags and sanitise string inputs to prevent injection | Input Sanitiser |
5. Exception Handling
- Rejected inputs generate a structured error log with: timestamp, source system, error code, field name, and reason.
- A daily error summary report is available in the DCKAP portal under Monitoring > Error Summary.
- Inputs rejected more than 3 times trigger an automatic alert to the customer’s designated admin.
