# Security

> Overview of security configuration options in CData Arc, including SSO, sign-in settings, network access, Admin API, and proxy settings.

The **Security** tab holds several categories of security-related configuration options, each of which has its own documentation topic:

* [Admin API Options](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/admin-api-settings.md) covers Cross-Origin Resource Sharing (CORS) settings and authentication token configuration for browser-based clients and API access.
* [Encryption at Rest](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/encryption-at-rest.md) supports application-level encryption at rest for [message data](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/activity.md#messages-tab). It addresses data-protection requirements for standards such as PCI DSS, HIPAA, GDPR, and SOX.
* [Network Access](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/network-access.md) options control IP-based access restrictions and provide additional security layers by managing trusted and banned IP ranges for protected resources.
* [Proxy Settings](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/proxy-settings.md) options enable you to configure global inbound and outbound proxy settings for network traffic routing and security.
* [Sign In Settings](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/sign-in-settings.md) options allow you to define global authentication requirements, password policies, and user account security measures including two-factor authentication and inactivity timeouts.
* [Single Sign-On (SSO) and User Provisioning](https://docs.arc.cdata.com/26.4/self-hosted/en/getting-started/administration/settings/single-sign-on.md) covers options for configuring single sign-on via SAML 2.0 or OpenID Connect authentication protocols, including integration with identity providers such as Microsoft Entra ID and Okta.
