A Double-Edged Sword: Security Threats and Opportunities in One-Sided Network Communication
It addresses security challenges for datacenter software systems adopting emerging network technologies, but appears incremental as it focuses on insights rather than novel solutions.
The paper examines the security implications of one-sided network communication technologies like RDMA and NVMe-over-Fabrics, highlighting both new threats that could undermine datacenter systems and unique opportunities to enhance security.
One-sided network communication technologies such as RDMA and NVMe-over-Fabrics are quickly gaining adoption in production software and in datacenters. Although appealing for their low CPU utilization and good performance, they raise new security concerns that could seriously undermine datacenter software systems building on top of them. At the same time, they offer unique opportunities to help enhance security. Indeed, one-sided network communication is a double-edged sword in security. This paper presents our insights into security implications and opportunities of one-sided communication.
