Prevention of Data Loss with SQLI

Nowadays, everyone uses web applications for the purpose of banking, e-commerce, entertainment, and so on. It bought a major change in the world. Its digitalized services made it available for the user remotely via the internet. It is also convenient for the user to access the services remotely. The majority of the services and transactions are happening with web applications, so it needs to store, process, send and receive the more sensitive data. The vulnerabilities present in the web applications allow the attacker to access the sensitive data of the legitimate users, the insecure web application allows intruders to access confidential data in an unauthorized way. The Structured Query Language Injection (SQLI) is a critical vulnerability for the web application. The existing SQLI is insecure for the sensitive data which is processed in the web applications. It allows the attacker to steal the sensitive data of the legitimate user. In this paper, we will discuss how this vulnerability is existing in the web application and also, how to avoid loss of the data even though SQLI is successfully performed on a website.
