OpenTeam security policies

Secure Software Development Lifecycle Policy

SSDLC requirements for ownership, threat assessment, secure implementation, review, security verification, release decisions, and ongoing maintenance.

Policy version 1.0 · Document and evidence status reviewed

Current evidence status

Policy documented; formal adoption and consistent execution not yet verified

Development guidance and focused internal security tests exist. An approved organization-wide SSDLC adoption record and complete lifecycle execution evidence have not been verified. The requirements below must not be used as proof that every release has already followed this process.

1. Ownership and governance

  • The engineering owner must maintain the SSDLC, assign an accountable security reviewer, and record the named approver and adoption date before representing it as formally adopted.
  • Each security-sensitive change must have an implementation owner and a reviewer. Where staffing limits independent internal review, document the limitation and obtain a qualified review before approval.
  • Review this policy at least annually and after material architecture, authentication, data-handling, or incident-response changes. Record revisions and role-appropriate secure-development training.

2. Requirements, data flows, and threat assessment

  • Identify sensitive data, permitted uses, retention and deletion needs, third-party processors, OAuth scopes, and the systems that store or transmit the data.
  • Document trust boundaries and threats for authentication, Team and account isolation, privilege escalation, connector actions, token handling, and agent or runtime execution.
  • Review new permissions, external endpoints, dependencies, storage, and infrastructure changes for least privilege and abuse cases before implementation. Maintain an architecture and data-flow record that matches the actual service.

3. Secure implementation and review

  • Use server-side authorization, validated inputs, safe output encoding, appropriate CSRF defenses, controlled outbound destinations, and safe error handling. Evaluate applicable OWASP risks.
  • Keep credentials out of source code, client-side bundles, URLs, logs, and test artifacts. Require protected transport, encrypted sensitive storage, and scoped access to secrets and connected accounts.
  • Review security-sensitive code and dependency changes before release. Record the change, reviewer, security considerations, and resolution of findings; distinguish dependency analysis from source-code security analysis.

4. Verification and release decision

  • Run applicable functional and negative security tests, source-code security analysis, dependency and secret checks, and authorized dynamic security tests under the Application Security Testing Policy.
  • Validate cross-Team and cross-account denial, OAuth state and token handling, credential redaction, and access to sensitive files and APIs. Preserve the tested version, test results, and coverage limits.
  • Block release for known exploitable critical findings. Resolve high-severity findings or document compensating controls, an accountable security approval, and an expiry date before release. Missing required verification must remain visible in the release decision.
  • Record the release approver, exact source and artifact identity, verification evidence, deployment authorization, and rollback plan. Server software installation or replacement requires explicit approval of the exact operation; security work does not authorize automatic updates.

5. Maintenance, incidents, and records

  • Review vulnerability notices and security reports, triage findings by severity and exposure, assign owners, and verify remediation. Prepare software updates for explicit approval rather than enabling unattended installation.
  • For a suspected incident, preserve evidence, contain exposure, revoke affected credentials where authorized, investigate, and make notifications required by applicable obligations.
  • Retain threat assessments, reviews, test evidence, release decisions, exceptions, and remediation/retest records under the evidence requirements in the security overview. An expired exception requires a fresh decision.
