How frequently are security audits conducted on the system?

At launch TLDs platform will be tested in simulated environments to establish future possible scenarios it could encounter. This is a collaborative effort and can be considered an internal audit of TLDs systems.

Before mainnet launch, TLD aims to have the robustness of its systems tested by independent auditors, at least once per year. And an audit is conducted with every major SC upgrade.

The total system includes the TLDs Infrastructure, database, network components, SC etc.
