Security professionals understand that these gaps exist and represent risks for them. In IDC's 2008 Enterprise Security Survey, only 46% of surveyed participants said that they were very confident or extremely confident of their existing enterprise security. IDC believes that this finding demonstrates a noticeable level of management uncertainty and a lack of confidence in existing security systems. The source of this lack of confidence is largely due to the understanding that existing infrastructures do have security gaps. The absence of an integrated view of what is happening in security infrastructures results in little to no visibility into where.
