According to Computing News, Secerno, a UK company involved in security, databases main weakness concerns inside attacks. The problem is related to the overabundance of people that have access to confidential data. To counter this weakness, Secerno has developed a program that mine standard usage of the database over a period of time. Once the program has learned, he could be used to detect non-usual queries. To my point of view, the main drawback lies in this critical period of learning. If bad usages of the database are made at this point, the system can allow future attacks.
