# Secure SDLC

> Public Secure Software Development Lifecycle model for Enigm.

Enigm follows a security-focused software development lifecycle designed to reduce software supply chain risk, improve code quality, support secure release processes, and preserve privacy-oriented platform design.

## Overview

The Enigm Secure SDLC defines the security capabilities and controls used to guide software from development through production release.

The lifecycle is designed to support:

* Software risk reduction.
* Code quality improvement.
* Release integrity.
* Early vulnerability detection.
* Protection of development assets.
* Secure release governance.

## Security Objectives

The Secure SDLC is designed to:

* Reduce software risk.
* Improve release integrity.
* Detect vulnerabilities early.
* Protect development assets.
* Improve operational security.
* Support secure release authorization.
* Support controlled production rollout.
* Preserve privacy, data minimization, and content confidentiality requirements during product and platform changes.

The objective is risk reduction and continuous improvement across the software lifecycle.

## Development Security Principles

Enigm development security is guided by:

* Defense in depth.
* Least privilege.
* Secure defaults.
* Separation of duties.
* Verification before release.
* Continuous validation.
* Change review.
* Controlled release authorization.

These principles are intended to reduce the likelihood that insecure code, unsafe configuration, or unauthorized changes reach production.

## Source Code Security

The development process includes controls for source code security.

Conceptual controls include:

* Automated code analysis.
* Peer review.
* Security review.
* Change validation.

Source code security controls are intended to identify defects, unsafe patterns, and security-sensitive changes before release.

## Dependency Security

Third-party dependencies are reviewed, monitored, and assessed for security impact.

Dependency security focuses on:

* Identifying vulnerable dependencies.
* Reviewing dependency risk.
* Reducing unnecessary dependency exposure.
* Supporting remediation when security issues are identified.
* Preserving awareness of dependency impact on release risk.

Dependency security reduces supply chain risk but does not eliminate it.

## Sensitive Material Protection

The Secure SDLC includes controls intended to prevent accidental exposure of sensitive credential material.

Sensitive material protection focuses on:

* Reducing the likelihood of sensitive credential exposure.
* Preventing sensitive material from being stored in source code.
* Supporting review of changes that may affect credential handling.
* Limiting access to sensitive development assets.
* Encouraging rotation and remediation when exposure is suspected.

Sensitive material protection is a lifecycle control and must be supported by operational discipline.

## Build Security

Build processes are designed to support integrity, traceability, and controlled release workflows.

Build security focuses on:

* Build input validation.
* Build artifact integrity.
* Traceability between changes and release artifacts.
* Separation between build production and release authorization.
* Controlled promotion toward release validation.

Build security does not replace release signing or production validation.

## Release Security

Production releases require validation and authorization before publication.

Release security includes:

* Release validation.
* Release authorization.
* Release integrity checks.
* Controlled publication.
* Rollout readiness review.

Release security relates directly to:

* Release signing.
* OTA security.
* Production gates.

Release signing establishes release authenticity. OTA security protects delivery, eligibility, and device verification. Production gates define expected production security posture.

## Vulnerability Management

The platform supports vulnerability management as part of the Secure SDLC.

Vulnerability management includes:

* Vulnerability identification.
* Risk assessment.
* Prioritization.
* Remediation workflows.
* Verification of remediation.

Vulnerability management is intended to reduce exposure and improve response to known security issues across the software lifecycle.

## Security Monitoring

Security visibility extends across the software lifecycle and operational environment.

Security monitoring may support:

* Visibility into security-relevant events.
* Review of release-related security outcomes.
* Identification of suspicious activity.
* Support for vulnerability response.
* Support for incident visibility.

Monitoring is a defensive visibility control. It does not replace secure development, review, or release validation.

See [Security Governance](/security/governance).

## Incident Response

Security incidents are evaluated, investigated, and addressed through controlled response procedures.

Incident response supports:

* Event triage.
* Impact assessment.
* Risk reduction.
* Remediation coordination.
* Lessons learned.

Incident response is intended to reduce impact and improve future controls when security issues occur.

## Continuous Improvement

Security controls are continuously reviewed and refined.

Continuous improvement includes:

* Reviewing security outcomes.
* Updating controls when risks change.
* Improving validation coverage.
* Refining release readiness expectations.
* Strengthening development security practices.

The Secure SDLC should evolve as Enigm products, platform controls, and threat conditions evolve.
