A new survey by MeriTalk reveals many government agencies may have an overly optimistic estimate about the length of time cyberthreats remain undetected on government networks. Nearly 90 percent of the cybersecurity professionals surveyed said they are unable to tell a complete story with the security data they gather, according to the study. Nearly 7 in 10 government cybersecurity professionals reported being overwhelmed by the volume of data being collected by the security systems. Some 78 percent said at least some of the data collected goes unanalyzed because they simply had neither the time nor the resources to do it.”]
