In recent years, the number and variety of cybersecurity products and services has grown rapidly.  One survey found that organizations use an average of 47 different cybersecurity tools across their networks. This has created challenges for organizations, who can find it difficult to make all of these different products interoperable. What could help would be a common set of standards, protocols, taxonomies, and open source code that can tie these cybersecurity tools together. This event will examine the progress of efforts to develop standards such as the Open Cybersecurity Alliance, and ask what the federal government and private firms can do to help advance interoperability. This event is made possible through general support to CSIS.
