Another good mitigation is the frameworks and strategies that we use to connect to databases. SQL statements should include bind variables and parameters. Now, you can write full statements or use bind variables. Creating full statements is susceptible to injection attacks because those statements are often concatenated with user input strings like in our previous example. But, when you use bind variables and parameters, you remove that risk because of how the drivers will create the statement for you and escape the dangerous behavior. Using a bind variable…
