Introduction

Purpose and Scope

This user guide describes the NTE INEN-ISO/IEC 27031 Go SDK, a comprehensive software development kit that implements the Ecuadorian technical standard NTE INEN-ISO/IEC 27031:2015 for Information Technology - Security Techniques - Guidelines for Information and Communication Technology Readiness for Business Continuity (ATCN).

The SDK enables organizations to systematically implement ICT business continuity management through a structured approach based on the Plan-Do-Check-Act (PDCA) cycle. This guide covers installation, configuration, usage, and maintenance of the SDK.

Target Audience

• Primary Users: Software developers integrating the SDK into applications
• Secondary Users: System administrators deploying ATCN solutions
• Tertiary Users: Compliance officers and auditors verifying implementations

Document Conventions

• Bold text: UI elements, buttons, and important terms
• Code blocks: Programming code and command-line instructions
• Notes: Important information requiring attention
• Warnings: Actions that could cause data loss or system issues

Concept of Operations

Overview of the SDK

The NTE INEN-ISO/IEC 27031 Go SDK provides a modular framework for implementing ATCN (Adecuación de TIC para la Continuidad del Negocio) principles in software applications. It automates the PDCA cycle for ICT business continuity management.

Key Components

• Core Framework: Implements the six ATCN elements (People, Facilities, Technology, Data, Processes, Suppliers)
• Service Layers: Planning, Operations, Monitoring, and Improvement phases
• Data Models: Structured representations of ATCN entities and processes
• Validation Engine: Ensures compliance with standard requirements

Operational Flow

1. Planning Phase: Define resources, requirements, and strategies
2. Operations Phase: Implement strategies and handle incidents
3. Monitoring Phase: Audit, review, and measure performance
4. Improvement Phase: Apply corrective and preventive actions

Integration Points

The SDK integrates with existing Go applications and can be deployed in various environments including on-premises servers, cloud platforms, and containerized systems.

Procedures

Installation

Prerequisites

• Go 1.21 or later installed on the target system
• Access to a Go module proxy or direct Git repository access

Installation Steps

1. Open a terminal or command prompt.

2. Navigate to your Go project directory.

3. Run the following command to add the SDK to your project:

   go get iso27031-sdk

4. Verify the installation by checking the go.mod file for the new dependency.

Post-Installation Verification

1. Create a simple test file to verify the SDK is accessible:

   package main
   
   import "iso27031-sdk"
   
   func main() {
       sdk := iso27031.NewSDK()
       // SDK is ready for use
   }

2. Run go build to ensure there are no compilation errors.

Configuration

Basic Configuration

1. Import the required packages in your Go application:

   import (
       "context"
       "iso27031-sdk"
       "iso27031-sdk/models"
   )

2. Initialize the SDK with default settings:

   sdk := iso27031.NewSDK()

Advanced Configuration

For production environments, configure custom validation rules and service implementations as needed. Refer to the API documentation for available configuration options.

Basic Usage

Creating an ATCN Instance

1. Create a new ATCN framework instance:

   atcn := &models.ATCN{
       ID:        "atcn-org-001",
       Name:      "Organization ATCN Framework",
       CreatedAt: time.Now(),
   }

2. Execute the PDCA cycle:

   ctx := context.Background()
   err := sdk.ExecutePDCACycle(ctx, atcn)
   if err != nil {
       // Handle error
   }

Handling Incidents

1. Create an incident record:

   incident := &models.Incident{
       ID:          "incident-001",
       Title:       "System Outage",
       Description: "Database server unavailable",
       Severity:    "high",
       DetectedAt:  time.Now(),
   }

2. Process the incident through operations services (implementation-dependent).

Advanced Operations

Custom Strategy Implementation

1. Define custom strategies for specific organizational needs.
2. Implement custom service interfaces for specialized requirements.
3. Integrate with external monitoring and alerting systems.

Performance Monitoring

1. Access monitoring services to conduct audits and reviews.
2. Review assessment results for compliance and improvement opportunities.
3. Implement custom metrics and reporting as needed.

Information for Uninstallation

Uninstallation Procedure

1. Remove the SDK dependency from your Go project:

   go mod edit -droprequire iso27031-sdk
   go mod tidy

2. Delete any custom code or configurations specific to the SDK.

3. If the SDK was installed globally, remove it from the Go cache:

   go clean -modcache

Data Removal

• The SDK does not persist data externally; all data is managed by the host application.
• Ensure that any ATCN frameworks, incidents, or assessments created using the SDK are properly archived or removed according to your organization's data retention policies.

Post-Uninstallation Verification

1. Attempt to build your application to ensure no residual dependencies.
2. Run your application's tests to verify functionality remains intact.

Troubleshooting

Common Issues

• Import Errors: Ensure the module path is correct and the SDK is properly installed.
• Compilation Errors: Verify Go version compatibility (1.21+ required).
• Runtime Errors: Check context cancellation and error handling in your code.

Support Resources

• Review the example code in the examples/ directory.
• Consult the API documentation for detailed method signatures.
• Check the GitHub repository for known issues and updates.
