Race conditions in real life
In particular, we will discuss the topics of security, file management, and networking. Race conditions don't simply exist in simple, minimal code examples about global counters. They are present in many important tasks such as security, file management, and networking. In this section, we will briefly discuss what some of these examples might look like from a theoretical perspective.
Security
Concurrent programming can have significant implications in terms of the security of the system in question. Recall that a race condition arises between the process of reading and altering the data of a resource; a race condition in an authenticating system can cause the corruption of data between the time of check (when the credentials of an agent are checked) and the time of use (when the agent can utilize the resource). This problem is also known as a Time-Of-Check-To-Time-Of-Use (TOCTTOU) bug, which is undoubtedly detrimental to security systems.
