Input validation is a crucial security practice that ensures the data entered into a system is correct, safe, and within expected parameters, reducing the risk of vulnerabilities like injection attacks. It involves checking the format, type, and range of input data before processing to prevent unauthorized access and data corruption.

Injection attacks are a type of security vulnerability where an attacker is able to execute malicious code or commands by exploiting input validation flaws in a program. These attacks can lead to unauthorized data access, data corruption, or system compromise, making them a critical concern for software security.

Data corruption refers to errors in computer data that occur during writing, reading, storage, transmission, or processing, leading to unintended changes to the original data. It can result from hardware failures, software bugs, or external interference, and may cause data loss, system crashes, or incorrect outputs.
