What limitation affects the speed of brute force attacks?

• A. The amount of network bandwidth
• B. The computing power available
• C. The number of attack vectors
• D. The complexity of encryption used

Answer: (B)

The speed of brute force attacks is primarily limited by the computing power available. A brute force attack involves systematically checking all possible passwords until the correct one is found. The effectiveness and speed of this approach are directly dependent on the number of calculations that can be performed per second, which is determined by the hardware being used. More powerful processors and systems can attempt a greater number of password guesses in a shorter amount of time, significantly speeding up the process. Conversely, if the attacker is using limited computing resources, the attack will be slower as fewer guesses can be processed in a given timeframe. Although factors like network bandwidth, the number of attack vectors, and the complexity of encryption can play roles in the broader context of a cyber attack or contribute to its overall effectiveness, they do not directly dictate the speed at which a brute force attack can execute its guesses. For example, even with high network bandwidth, if the computational resources are inadequate, the speed of the brute force attack will still be hindered. Similarly, the choice of attack vectors does not impact the computational efficiency of brute force methods, while encryption complexity primarily relates to the strength of passwords rather than the speed of the attack itself.
