The article discusses the most common
web application security threats and provides prevention techniques from the point of view of a
security expert. The threats include SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), broken
authentication and
session management, security misconfiguration, insecure cryptographic storage, and insufficient authorization and
access control. The prevention techniques involve
parameterized queries,
input validation, anti-CSRF tokens, strong
password hashing algorithms, session timeouts, and re-authentication requirements, regular
security audits, strong
encryption and hashing algorithms, role-based access control (
RBAC), and implementing
access controls based on the
principle of least privilege. The article emphasizes the importance of understanding and preventing these threats to protect sensitive data and maintain user
trust.
