Sql Injection — CompTIA CySA+ (CS0-003) Practice Questions

SQL injection is an attack technique in which maliciously crafted input is inserted into a database query, allowing an attacker to manipulate query logic to read, modify, or delete data, bypass authentication, or in some cases execute commands on the underlying system. CySA+ candidates must be able to recognize indicators of SQL injection in web logs and application output, understand its root cause in insufficient input handling, and recommend appropriate mitigations such as parameterized queries and web application firewalls. The CS0-003 exam addresses SQL injection within the broader context of web application vulnerability assessment and software security. It remains one of the most prevalent and impactful vulnerability classes tracked by industry bodies such as OWASP.
