Database security is important because database store the most valuable information in an organization, such as customer records, financial data, and internal systems. One common issue is SQL injection, where an attacker sends harmful commands through a website or form. If the system is not properly protected, the attacker ca access or even delete the database. This often happens when input fields are not validated. Another major issue is weak access control., Sometimes employees are given more privileges than they need, or old accounts are never removed. This can lead to unauthorized access, accidental data exposure or insider misuse.
