Hardware acceleration techniques

Definition

Hardware acceleration techniques refer to the use of specialized hardware components to perform specific tasks more efficiently than general-purpose processors. These techniques are particularly important in network security, as they can enhance the performance of firewalls and other security appliances by offloading resource-intensive processes, such as encryption and packet inspection, from the CPU to dedicated hardware. This results in faster data processing and improved overall system performance, enabling the device to handle higher traffic loads without compromising security.
