Race Conditions

Definition

The main vulnerability lies were multiple threads could be working on a shared resource without proper locking mechanism

Mitigation

We will list a few mitigation techniques.

• Synchronization Mechanisms: Modern programming languages provide synchronization mechanisms like locks. Only one thread can acquire the lock at a time, preventing others from accessing the shared resource until it’s released.

• Atomic Operations: Atomic operations refer to indivisible execution units, a set of instructions grouped together and executed without interruption. This approach guarantees that an operation can finish without being interrupted by another thread.

• Database Transactions: Transactions group multiple database operations into one unit. Consequently, all operations within the transaction either succeed as a group or fail as a group. This approach ensures data consistency and prevents race conditions from multiple processes modifying the database concurrently.
