SQL Injection Attacks are a type of web security vulnerability where an attacker inserts malicious SQL queries into input fields or URLs to manipulate a website's database. These attacks can lead to unauthorised access, data leakage, and data manipulation.
In an SQL injection attack, the attacker exploits improper handling of user input in SQL queries. By injecting malicious SQL code, they can potentially:
Access Sensitive Data: Retrieve sensitive information from the database.
Modify Data: Alter or delete data stored in the database.
Execute Arbitrary Commands: Execute arbitrary SQL commands on the database.
SQL injection attacks pose significant risks:
Data Exposure: Attackers can access, steal, or manipulate sensitive data.
Data Loss: Important data may be deleted or altered. system.
Application Compromise: Attackers can gain control over the application.
Regulatory Compliance: Violations may result in legal and regulatory issues.
Preventing SQL injection involves:
Prepared Statements: Use parameterized queries or prepared statements.
Input Validation: Validate and sanitise user input.
Least Privilege: Limit database user privileges.
Web Application Firewall (WAF): Implement a WAF to filter malicious SQL queries.
