Managing identity and access in multi-cloud serverless setups can be tricky, but it’s crucial for security and scalability. Here’s a quick summary of what you need to know:

• Centralized Identity Management: Use a single Identity Provider (IdP) supporting SAML 2.0, OAuth 2.0, and OIDC to simplify operations and strengthen security.

• Least Privilege Access: Grant the minimum permissions necessary for each function, review regularly, and use short-term access tokens for added safety.

• Secret and Configuration Management: Store sensitive data like API keys and credentials securely with cloud secret storage services and enforce strong encryption (e.g., AES-256, TLS 1.3).

• IAM Policy Automation: Manage IAM policies as code (PaC) for consistency, automate compliance checks, and integrate security into your infrastructure code.

Key Challenges and Solutions:

• Policy Inconsistency: Centralize policy management.

• Identity Sprawl: Use federated identity solutions.

• Access Key Proliferation: Automate key rotation.

• Compliance Tracking: Deploy unified logging and monitoring.

Movestax simplifies these practices with tools for authentication, identity federation, token management, and policy automation - all designed for serverless environments.

Start by centralizing IAM, enforcing least privilege, and automating policies to secure your multi-cloud serverless setup effectively.

Central Identity Management Setup

Centralizing identity management across multiple cloud platforms enhances security in serverless environments. This approach simplifies operations, strengthens access controls, and streamlines processes.

Single Identity Provider Setup

Select an Identity Provider (IdP) that supports SAML 2.0, OAuth 2.0, and OIDC. When setting up a single IdP, pay attention to these key components:

Movestax includes a built-in authentication system with pre-configured workflows, eliminating the need for custom setups while delivering robust security.

Identity Federation Methods

Identity federation involves creating secure trust relationships between systems. Key areas to focus on include:

1. Trust Chain Configuration: Establish secure trust connections between your main IdP and each cloud provider.

2. Attribute Mapping: Ensure user attributes are consistently mapped across platforms.

3. Session Management: Implement unified session timeouts for better control.

Movestax simplifies federation with its unified platform, which integrates app, database, and authentication management across cloud environments. To ensure effective federation, configure your identity management system to:

• Centralize user lifecycle management

• Apply consistent access policies across all platforms

• Automate user provisioning and deprovisioning

• Enable immediate access revocation when necessary

With its serverless-first design, the platform automatically scales identity management alongside your applications, removing the need for traditional authentication infrastructure.

Up next: refining access controls with least privilege rules.

Least Privilege Access Rules

Using least privilege access helps tackle issues like identity sprawl and inconsistent policies in multi-cloud serverless setups. By setting clear permission boundaries and access controls, you can lower risks while keeping operations efficient.

Permission Level Settings

Set detailed permissions for each serverless function. Begin with no permissions and add only what’s necessary. Focus on these areas:

Movestax simplifies this process with built-in role templates. These templates ensure secure configurations by default while allowing adjustments to meet your unique needs.

Short-Term Access Tokens

Time-limited access credentials are a smart way to lower the risk of exposure. Configure your serverless functions to:

• Use tokens with a maximum lifespan of 1 hour for routine tasks

• Generate temporary credentials for scheduled jobs

• Automatically rotate tokens

• Activate just-in-time access for critical operations

Movestax's authentication system handles token management automatically, including rotation and expiration, making security easier to maintain.

Access Key Management

A strong system for managing access credentials is essential for serverless setups. Here’s how to stay on top of it:

• Review permissions quarterly and remove unused credentials

• Monitor access patterns continuously, with alerts for anomalies like failed logins, unusual times, or geographic changes

• Rotate credentials systematically: function keys every 30 days, database credentials every 60 days, service tokens every 90 days, and API keys every 180 days

Movestax also offers built-in monitoring tools that flag suspicious activity, helping you maintain security without extra hassle.

Next, focus on securing your serverless environment by effectively managing secrets and configurations.

Secret and Config Management

Protect sensitive credentials and operational settings to secure multi-cloud serverless environments. This complements earlier IAM practices by focusing on safeguarding secrets and configurations.

Cloud Secret Storage Services

Using dedicated cloud storage services for secrets management is a smart approach. These solutions handle secure storage, credential rotation, and access control for sensitive data like API keys, database credentials, service tokens, and encryption keys. Movestax simplifies this process by automating credential rotation and securely distributing them to your serverless functions. Secure storage also lays the groundwork for strong encryption practices, which we’ll cover next.

Data Encryption Standards

Strong encryption is essential for protecting data in your serverless setup:

• Use AES-256 to encrypt data at rest

• Secure data in transit with TLS 1.3

• Enable end-to-end encryption for critical operations

• Apply envelope encryption and assign separate keys for each environment

Movestax supports automatic encryption key management and rotation, making it easier to maintain these standards. With encryption in place, securely managing configurations becomes the next priority.

Config Storage Best Practices

Configurations need to strike a balance between security and accessibility. Here’s how to manage them effectively:

• Securely store environment-specific configuration data and use version-controlled templates

• Create a configuration hierarchy, from system defaults to runtime variables

• Limit configuration access based on service roles and deployment stages

Movestax offers isolated configuration spaces for each service and environment, ensuring controlled access. Configurations are stored immutably with version control, allowing for reliable tracking and rollbacks when needed.

IAM Policy Automation

Strengthening identity controls is just the start - automating IAM policies takes security in multi-cloud serverless environments to the next level. By automating these policies, you minimize errors and ensure consistent security across deployments. This approach works hand-in-hand with the centralized identity and access controls discussed earlier.

Policy Code Management

Managing IAM policies as code (PaC) brings structure and automation to your security efforts. Here’s how it helps:

• Track changes: Use Git repositories to monitor and document policy updates.

• Collaborate effectively: Enable peer reviews for security updates.

• Quick recovery: Roll back any problematic changes with ease.

• Maintain consistency: Apply uniform security standards across all environments.

Movestax simplifies this process with built-in policy templates and Git integration. It ensures policies are correctly formatted and flags common security issues before deployment.
