Because Cordova bundles are effectively application code, tampering can expose sensitive data or compromise devices. Harden your OTA system with these layered controls.
Sign Everything
Create a dedicated code-signing key stored inside an HSM or managed KMS. Every bundle should be hashed, signed, and verified on device before extraction. Rotate keys annually and revoke old keys inside the client. Pair signatures with strict version manifests to prevent downgrade attacks.
Protect Secrets and Infrastructure
Restrict who can upload bundles. Require MFA and issue auditable service accounts for CI.
Serve updates from TLS-only origins with modern ciphers. Pin certificates inside your client if possible.
Encrypt rest buckets, limit lifecycle to the releases required for your rollback strategy.
Enforce Policy through Automation
Codify governance rules inside CI: run SAST, dependency audits, and vulnerability scans before packaging. Gate deployments via the rollout framework so risky builds never reach production. Document and rehearse your incident response steps alongside the communication plan.
When stakeholders trust that OTA updates are tamper-proof and observable, they’re far more likely to champion the faster delivery cadence.
