It’s good common sense to secure databases as well as or better than other systems in the enterprise. But it’s not that simple. In this white paper, we take a look at the shortcomings of the database security tools used by enterprises worldwide and the technology and approach required to provide real-time, comprehensive protection for all types of databases. Components of Database Security A wide array of technologies and tools are currently used to provide various aspects of database security. As with other areas of IT security, no single tool can provide an ironclad defense against all threats and abuses. It’s best to implement a combination of tools to achieve adequate security. The two main categories of tools in use across enterprises large and small are authentication/access “I hack, I ruin, I make piles of control and native database audit tools. money.” Authentication and access control —Andrew Auernheimer The ability to designate roles, logins, and passwords is the most basic and most widely used level of (Charged in US Federal Court with database security.
