Traditionally, security information and event management (SIEM) systems collect data from enterprise networks, applications, and logs from operating systems, databases, and other sources. Doing that on-premises is standard practice and something that’s well understood, but for cloud deployments it gets a little tricky.
According to a study released last month by the research firm Quocirca, only 2.5 percent of enterprises have full visibility across all their infrastructure. For example, 69 percent of companies say they have good or excellent visibility into their on-premises servers; for IaaS, SaaS, and PaaS environments, however, the results drop to 58, 57, and 54 percent, respectively.
