Study Notes
SQL Injection Risks and Prevention
- One of the biggest security risks when developing databases, especially if using dynamic SQL, is SQL Injection.
- SQL Injection occurs when an attacker inserts malicious code as user input, which is then executed by the database, allowing unauthorized access to sensitive data.
How SQL Injection Occurs
- SQL Injection can occur when user input is not properly sanitized, and dynamic SQL is used to construct database queries.
- Attackers can inject malicious code, such as additional SQL statements or conditional statements, to manipulate the database.
Consequences of SQL Injection
- A successful SQL Injection attack can allow a hacker to:
- Extract sensitive data, such as passwords or credit card numbers
- Modify or delete data
- Gain unauthorized access to the system
- Execute system-level commands
When is SQL Injection More Likely?
- SQL Injection is more likely to occur when:
- Dynamic SQL is used
- User input is not properly validated and sanitized
- Least privilege principles are not followed
Database Interactions and SQL Injection
- Interactive database interactions, such as web forms, increase the susceptibility to SQL Injection.
Importance of Awareness
- It is essential to be aware of SQL Injection risks to prevent unauthorized access to sensitive data.
Success of SQL Injection Attacks
- A key reason for the success of SQL Injection attacks is the lack of parameterization, which allows attackers to inject malicious code.
Lack of Parameterization
- Lack of parameterization contributes to SQL Injection vulnerability by allowing attackers to inject malicious code as user input.
Common Reasons for SQL Injection Success
- Another common reason for the success of SQL Injection attacks is the failure to tie back the principle of least privileges.
Preventing SQL Injection
- A key element to preventing SQL Injection attacks is to use parameterized queries and validate user input.
- Dynamic SQL and lack of parameterization are considered vulnerabilities for SQL Injection, and should be avoided.
- Following the principle of least privileges is crucial in preventing SQL Injection attacks.
