- Never give excessive privileges to employees of the company and ensure that outdated ones are revoked on time.
- SQL injections – This is a common database security threat and comes in the form of an attack with a malicious code embedded in the frontend or web applications and later passed over to the backend database. As a result of these SQL injections, cybercriminals can have unrestricted access to data stored in the business database. There are two kinds of SQL injection attacks, and they are-
- SQL injection that targets traditional databases
- NoSQL injections that target larger databases
- Stored procedure that is used instead of direct queries
- The incorporation of the MVC architecture
- Weak audit trails – If a business database is not audited well, it presents non-compliance risks with both national and critical international regulations for data security. A business must record and register all its database events, and the business must deploy solutions for automatic auditing. If there is unwillingness or an inability to carry this out, this represents a grave risk on several levels.

- The database and its backups should both be audited. This helps in identifying the individual who has been attempting to get access to sensitive business data.
- Database misconfigurations and vulnerabilities- It often occurs that databases are completely unprotected because of misconfiguration. Some systems have default accounts as well as configuration parameters. Note, business owners should remember that hackers are themselves qualified IT professionals and specialists who are well-equipped on the measures on how to exploit vulnerabilities and misconfigurations of the database and deploy them for attacking the business.
- The databases should not have any default accounts
- The IT personnel in the business should be highly experienced and qualified in database administration and management.
- Lack of education and expertise in IT security – Databases tend to get leaked and breaches due to the inadequate levels of expertise in IT security. Employees that have no technical experience are not educated, and they often put the database at risk and break security rules. The database security personnel might lack the knowledge to incorporate security controls, enforce the necessary policies, and conduct incident response processes proactively.
- Users of the database should be educated extensively in the field of database security
- Specialists in IT security and database management should be encouraged to upgrade to their professional levels and existing qualifications. If you are a small business owner and cannot afford a full-time IT specialist, you should hire credible remote DBA companies for the task.
