Suricata: Impact of NIC Offloading on File Extraction
Introduction : In the world of network security, Suricata stands as a powerful tool for detecting and preventing malicious activity. With its ability to analyze network traffic in real-time, Suricata has become an invaluable asset in the battle against cyber threats. However, when it comes to enabling file extraction in Suricata, there is an important consideration that often goes overlooked: NIC offloading. Understanding NIC Offloading : NIC offloading refers to the process of delegating certain network processing tasks to the Network Interface Card (NIC) hardware itself, relieving the host system's CPU from the burden of handling these tasks. Offloading operations such as checksum calculation, segmentation offloading, and TCP/IP reassembly to the NIC can significantly enhance network performance by reducing CPU overhead. File Extraction in Suricata : One of Suricata's key features is its ability to extract files from network traffic for further analysis. This...
