AlertLogic, a Houston-based cloud security company, has issued a report on cloud security, based on threat data from more than 1,800 customers. The data cut used in this slideshow focuses on cloud-hosting provider customers served by AlertLogic. "Occurrence" is defined as the percentage of customers impacted by each threat type. "Incident Frequency" translates to how often impacted cloud-hosting provider customers experienced each threat type, by average. The major finding, according to the vendor, suggests that on-premise security may not be stronger than security in the cloud.
