+# Compliance & Audit Considerations
+
+## Executive Summary
+
+Cocos is a secure, open-source platform designed for compliance-sensitive environments.
+
+It combines **hardware-based isolation**, **Trusted Execution Environment (TEE) attestation**, and **hardened runtime security** to protect sensitive workloads and meet the highest audit and regulatory standards.
+
+Through **Trusted Execution Environments (TEEs)**, **Attested TLS**, and **transparent architecture**, Cocos ensures that data and algorithm remain confidential, verifiable, and auditable — making it a trusted foundation for regulated industries such as finance, healthcare, and government.
+
+## Overview
+
+Cocos is designed with strong security guarantees to meet the needs of compliance-driven environments, ensuring confidentiality, integrity, and auditability for sensitive workloads. By combining hardware-backed TEEs, TEE attestation, and hardened runtime configurations, Cocos provides a foundation for meeting strict regulatory requirements.
+
+## Trusted Execution Environments (TEEs)
+
+Cocos supports hardware TEEs such as AMD SEV-SNP, Intel TDX, and Confidential VMs. These technologies:
+
+- Isolate workloads from the host OS and hypervisor
+- Protect data in use from unauthorized access
+- Reduce the Trusted Computing Base (TCB) by running only essential components inside the CVM
+
+This isolation ensures that even privileged system software cannot access protected data or code.
+
+## Remote Attestation
+
+Cocos implements remote attestation to verify the integrity of workloads at runtime. This includes:
+
+- Measuring the initial code and data of the CVM before the CVM is started
+- Measuring the boot process. This means that the kernel, initramfs, and kernel command line are measured
+- Providing verifiable attestation reports to external verifiers
+- Using **Attested TLS**, embedding attestation evidence directly into the X.509 certificate
+
+These capabilities enable customers and auditors to verify that workloads run only in trusted, untampered environments.
+
+## Integrity & Isolation
+
+To maintain operational integrity and reduce attack surfaces, Cocos incorporates:
+
+- **Linux Integrity Measurement Architecture (IMA)** to hash and keep track of opened files, before the files are executed
+- Runtime image that disables unnecessary services (e.g., SSH)
+
+This ensures that system components remain unchanged and trustworthy throughout their lifecycle.
+
+## Secure Communications
+
+All Cocos components communicate over encrypted channels with strong authentication:
+
+- TLS with certificate-based authentication
+- Attestation report bound to X.509 certificate
+- Protection against man-in-the-middle and replay attacks
+
+This ensures data-in-transit encryption and binds the attestation report to the TLS secure channel.
+
+## Auditability & Transparency
+
+Cocos is open source under the Apache 2.0 license, enabling:
+
+- Independent code review and verification
+- Transparent security architecture
+
+This transparency builds trust and supports regulatory compliance audits.
+
+## Continuous Security Improvements
+
+Security features are continuously enhanced with each release. Examples include:
+
+- SSH hardening
+- Virtual TPM (vTPM) integration
+- Expanded secure cloud integrations
+
+## Summary
+
+Cocos provides a secure and auditable platform ready for deployment in compliance-sensitive environments. Through hardware-backed isolation, TEE attestation, encrypted communications, and an open-source security model, Cocos enables organizations to meet modern data protection and audit requirements with confidence.
