The more easily a malicious entity can pass in unfiltered SQL to the database server(s), the more susceptible your data will be to loss or theft. Place All Database Logic within Stored Procedures In today's blog, we'll explore a few practices that can greatly reduce exposure to SQL Injection attacks.
