Data security refers to the collective measures used to protect and secure a data or database management software from illegitimate use, corruption, unauthorized access, malicious threats, and attacks. The most common security attacks occur in the form of SQL injection, buffer overflow, denial of service(DOS) attacks, password attacks, malware, phishing, and cross-site scripting attack. Backend data security is very vital as it helps to prevent security attacks and also protect users' data from getting into the wrong hands.
