Securing native agents on untrusted machines requires implementing cryptographic code signing, mTLS for communication, secure key storage, and continuous integrity checks to prevent malicious modification. This ensures agent trustworthiness across deployment, updates, and runtime operations.

Tampering detection for endpoint agents is implemented through continuous integrity checks and health attestations that proactively report anomalies. This mechanism verifies the agent has not been maliciously modified during deployment or while operating in hostile environments.

Secure OTA updates for IoT agents are handled by facilitating cryptographically signed and verifiable update packages with rollback and kill-switch support. This maintains package integrity over time and allows rapid response if a compromised update is deployed.

mTLS authentication secures agent and control plane communication by using per-agent certificates alongside token-based methods. This mutual authentication ensures that only verified native agents can exchange data with the central control plane over the network.

System keychains can be used for secure secret storage across different operating systems to prevent casual access to credentials. This approach stores agent secrets locally using native OS encryption rather than relying on plaintext configuration files.

Code signing and notarization are needed for agent installation to ensure platform-specific installer integrity and prevent tampering during deployment. These cryptographic verifications establish trust on Windows, macOS, and Linux before the agent executes.
