The Zero Trust security model has emerged as a critical strategy for protecting organizational assets. Zero Trust is based on the principle of maintaining strict access controls and not trusting anyone by default, regardless of whether they are inside or outside the network perimeter.

Many organizations moving from an on-premises solution to the cloud have previously relied on the network perimeter to control access so that anyone inside the network can push or pull artifacts. Moving to the cloud provides an opportunity to strengthen your security posture and thoughtfully design appropriate controls.

As a comprehensive artifact management platform, Cloudsmith integrates Zero Trust security principles to provide robust protection for software supply chains. Here's how Cloudsmith helps organizations like yours implement Zero Trust security, in five simple steps:

Step 1: Provisioning Developers With Zero Trust Access
Step 2: Securing Build Pipelines With Trusted Publishing
Step 3: Continuous Monitoring and Validation
Step 4: Managing Access to 3rd Parties
Step 5: Vulnerabilities in Software Packages

Step 1: Provisioning Developers With Zero Trust Access

Imagine you need to provision thousands of developers with Cloudsmith accounts. Using traditional security models, each developer might automatically gain broad access to your software repositories, potentially leading to security risks. Cloudsmith’s Zero Trust approach, however, ensures that no developer has access by default until explicitly granted.

Technologies and Setup

SCIM Integration: Use SCIM to automatically provision and deprovision Cloudsmith user accounts based on their status in your Identity Provider (IdP). This ensures that only active developers have access.
SAML Single Sign On (SSO): Use SAML so users can use their existing SSO provider to manage and control access to their Cloudsmith organization account.
SAML Group Sync: Use SAML Group Sync to integrate with your IdP to map groups to Cloudsmith teams. This automates the assignment of developers to specific teams with predefined permissions.

Granular Privilege Management: Control the default privileges at both global and repository levels. Developers can be granted read-only access to ensure they cannot move or upload artifacts until explicitly permitted.

Cloudsmith UI: access management controls — Repository privileges give you fine-grained control over the minimum privilege level required to perform specific actions and the actions users can perform.

Benefits

Least Privilege Principle: Developers only have access to the resources they need, reducing the risk of unauthorized access and potential breaches.
Automated Access Control: Streamlined management of user permissions through IdP integration ensures that access remains up-to-date and secure.

Cloudsmith UI: team controls — Users can be placed into teams, invited directly into a team, or automatically mapped to a team.

Step 2: Securing Build Pipelines With Trusted Publishing

Securing build pipelines with Trusted Publishing involves using OIDC to authenticate into CI/CD pipelines to ensure that only trusted systems can publish packages.

Technologies and Setup

Benefits

Enhanced Security: Ephemeral tokens and strict API key policies reduce the risk of token misuse and unauthorized access.
Simplified Compliance and Management: Automatic API key rotation reduces the administrative burden and helps you comply with stringent security standards, ensuring that security practices align with Zero Trust principles.
Trusted and Secure Publishing: Integrating OIDC and robust API key policies in your CI/CD pipelines protects against the risks of token exfiltration and abuse, making your software delivery process secure and trustworthy.

Step 3: Continuous Monitoring and Validation

Continuous monitoring and validation are core to the Zero Trust model. They ensure that all user activities and sessions are constantly verified for security compliance.

Technologies and Setup

Client and Audit Logs: Real-time activity logs capture detailed information about who is accessing your packages and from where. Audit logs provide a comprehensive record of all changes made within the Cloudsmith platform.
Session Management: SAML session times are defined by the IdP, ensuring that session durations comply with your organization's security policies. Regularly expiring sessions and requiring re-authentication allow you to maintain ongoing session integrity and security.

Benefits

Real-Time Visibility: Detect and investigate unusual patterns or unauthorized access attempts promptly.
Session Security: Regular re-authentication ensures that active sessions remain secure and compliant with your organization's security policies.

Step 4: Managing Access to 3rd Parties

It's essential to provide access to third parties without compromising security—like customers who need access to your packages. Cloudsmith’s entitlement tokens offer a solution for fine-grained access management.

Technologies and Setup

Entitlement Tokens: Cloudsmith’s entitlement tokens grant read-only access to repository contents, allowing you to control and track your customers' downloads.

Benefits

For vendors distributing software, Cloudsmith’s entitlement tokens give you precise control over who can download your software, track usage, and manage licenses.
Customizable Entitlement Tokens: Each customer or user can receive a unique entitlement token that grants access to specific packages or files. This setup allows for granular control and tracking of downloads.
Revocable Access: Tokens can be revoked if needed, such as when a subscription lapses, ensuring that access is always up-to-date and secure.

Step 5: Vulnerabilities in Software Packages

Cloudsmith integrates scanning and policy enforcement to uphold Zero Trust principles on your software packages so that only verified and validated packages are deployed to production.

Technologies and Setup

Vulnerability and Malware Scanning: Automated scans are conducted when packages are published to detect vulnerabilities and malware in packages before they are deployed.
Provenance Verification: Signing every package means that it can be verified by checking signatures and ensuring they originate from trusted sources.
OIDC Authentication: Continued use of OIDC ensures that only authorized and authenticated entities can publish or access packages.

Benefits

Packages are automatically scanned and validated against security policies, helping prevent vulnerabilities from reaching production environments.
