Make critical logic flows thread safe
Summary
Critical and high-value business logic flows must be thread safe and resistant to time-of-check and time-of-use (TOCTOU) race conditions.
Description
A race condition occurs when a code sequence requires exclusive access to a resource but another code sequence can modify the same resource before the first one has released it. This can have security implications if it occurs during high-value business logic flows, such as authentication, authorization and session management. Therefore, threads and concurrent processes must be managed carefully in order to prevent race conditions from arising.
