How to Secure Open Source Dependencies in Enterprise Software Supply Chains

·2 views

Public package registries like npm and PyPI lack built-in mechanisms to detect malicious or compromised dependencies, exposing enterprise pipelines to hidden risks. Security engineers recommend generating a Software Bill of Materials (SBOM) using tools like Syft and Grype to continuously scan for vulnerabilities before they reach production. Provenance and attestation practices ensure that software binaries have a verified cryptographic build history and meet security requirements before deployment. Cryptographic signing frameworks such as Sigstore can enforce governance policies, blocking unsigned or unverified artifacts from entering a cluster. Experts advise organizations to shift security checks upstream, verify dependency provenance, and adopt closed-loop supply chain solutions to reduce exposure.

IRIS 2025.2 Introduces Native OAuth2 Support for Web Application Authentication

InterSystems IRIS 2025.2 now supports OAuth2 as a native authentication method for web applications, eliminating the need for manual token-validation workarounds. OAuth2 allows third-party apps to access protected APIs using scoped, time-limited, and revocable access tokens instead of sharing user credentials. A typical setup involves four roles: a resource owner, a client app, an authorization server such as Keycloak, and IRIS acting as the resource server that validates tokens and enforces access rules. IRIS can now parse an incoming access token and automatically establish a user context, including username and roles, similar to how other authentication types work. A hands-on demo using Docker, Keycloak, and Postman is available on Open Exchange to help developers reproduce and explore the integration locally.

Developer Shares Why He Switched from Relational Databases to MongoDB

A software developer has shared his experience transitioning from relational databases like PostgreSQL to MongoDB after hitting scalability and flexibility limits. He found that managing schema migrations and horizontal scaling for write-heavy, globally distributed applications was consuming too much development time. MongoDB's document-based, flexible schema model allowed him to prototype faster and evolve his data structure alongside application code. He noted that MongoDB's built-in AI features and cost-effective infrastructure made it a better fit for modern application demands. The developer acknowledged that relational databases remain superior for complex multi-table joins, emphasizing that the choice should depend on the specific use case.
