Secure SDLC

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. This document is intended for security auditors, enterprise customers, technical partners, and security engineers.

​

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.

The diagram is conceptual and describes lifecycle validation stages at a public architecture level.

​

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 where applicable.

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.

​

Ongoing Security Validation

Enigm performs continuous and periodic security validation activities intended to reduce software, configuration, and exposure risk across supported environments. Validation practices may include:

• Automated vulnerability assessment.
• Infrastructure exposure reviews.
• Security posture validation.
• Configuration reviews.
• Attack surface monitoring.
• Security control validation.
• Periodic adversarial testing.
• Simulated attack exercises.
• Continuous monitoring.
• Security review cycles.

​

Periodic Security Assessments

Enigm performs recurring security assessments intended to identify vulnerabilities, misconfigurations, and exposure risks across supported environments. Assessment findings are prioritized according to risk, and remediation activities are tracked and verified where applicable.

​

Adversarial Security Testing

Enigm performs periodic adversarial security exercises intended to simulate attacker behavior and evaluate detection, visibility, and defensive controls. These exercises are intended to improve:

• Detection capabilities.
• Security monitoring.
• Incident response readiness.
• Defensive controls.
• Security posture.

​

Continuous Security Validation

Security controls are reviewed on an ongoing basis through automated and manual validation processes. Continuous validation supports early detection of security regressions, configuration drift, exposure changes, and control failures.

​

Governance

Security reviews occur regularly. Security posture is periodically reassessed, findings are prioritized according to risk, and remediation activities are tracked and verified.

​

Compliance

Enigm maintains ISO 27001 certification as part of its information security governance program. Compliance and governance practices include:

• Information security governance programs.
• Periodic independent reviews.
• Annual compliance assessments and audit processes.
• Alignment with recognized security frameworks.
• Alignment with recognized NIST security guidance and standards where applicable.

Enigm incorporates post-quantum cryptographic algorithms standardized by NIST as part of its cryptographic architecture.

​

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.

​

Security Limitations

No software development lifecycle can eliminate all risk. Limitations include:

• Vulnerabilities may remain undiscovered before release.
• Reviewed code can still contain defects.
• Dependencies may introduce future risk.
• Authorized changes may still have unintended security impact.
• Monitoring may not detect every issue.
• Incident response may depend on available evidence.

The goal of the Secure SDLC is risk reduction, release integrity, and continuous improvement.
