Avoiding SQL Injection
SQL injection is one of the oldest and most damaging web vulnerabilities, yet it remains common. It lets an attacker trick your database into running commands it should never run — reading, altering or deleting data they have no right to.
The good news is that it is entirely preventable with disciplined coding, which we apply throughout every project.
How the Attack Works
If user input is pasted directly into a database query, a malicious value can break out of the data and become part of the command itself. A search box could be turned into an instruction to dump your entire customer table.
How We Prevent It
- Parameterised queries: input is always treated as data, never as commands.
- Input validation: we reject values that do not match the expected shape.
- Least privilege: the app account cannot do more than it needs, limiting any damage.
Defence in Depth
We combine these measures with code review and automated testing so a single oversight does not open a hole. Security is built in from the start, not bolted on afterwards.
