In this talk, we will dive into io_uring, the Linux kernel's groundbreaking I/O technology that is redefining asynchronous processing. We'll explore how io_uring dramatically enhances system performance by reducing overhead and enabling unprecedented efficiency in I/O operations. However, this increased power brings significant security considerations. We will review the current state of auditing and security controls within the Linux kernel for this powerful feature. Finally, we will demonstrate how security visibility tools such as Kunai can provide essential visibility into io_uring operations on Linux endpoints, helping to bridge the gap between performance and security.
