Data Security Best Practices
Databases have become increasingly sophisticated over the last decades. The relational database is the most common. This technology allows data to be viewed in dynamic ways based on the user’s or administrator’s needs. The most common language used to communicate with databases is Structured Query Language (SQL). SQL allows users to pass queries to database servers in real time. This flexibility causes a major vulnerability when it isn’t securely implemented. Don’t confuse the language SQL with Microsoft’s database product SQL Server, though, like most databases, SQL Server uses Structured Query Language.
Early database systems connected the end user directly to the data through applications. In a private network, physical security was usually all that was needed to protect the data.
