SQL Injection | Cyber Security Fundamentals | SNS Institutions

SQL injection (SQLi) is a critical web security vulnerability that occurs when an attacker inserts or "injects" malicious SQL commands into an application's input fields. These commands are designed to manipulate the backend database, allowing unauthorized users to interfere with the queries the application makes. By exploiting this flaw, attackers can bypass login security, view sensitive data belonging to other users, or even retrieve the content of the entire database. In more severe cases, an attacker can modify or delete database records, leading to persistent changes in application behavior or complete data loss. The vulnerability typically stems from a failure to properly sanitize user input, allowing executable code to be processed as ordinary data. Common attack vectors include web forms, search boxes, and URL parameters where user data is directly concatenated into a query string. High-profile incidents like the 2019 Capital One breach highlight the devastating real-world impact of these attacks. #snsinstitutions #snsdesignthinkers #designthinking
