Security

This section could use some updates. Consider contributing !

Security is a broad topic. Unless you have considerable experience, a security background, or are applying for a position that requires knowledge of security, you probably won't need to know more than the basics:

  • Encrypt in transit and at rest.
  • Sanitize all user inputs or any input parameters exposed to user to prevent XSS and SQL injection .
  • Use parameterized queries to prevent SQL injection.
  • Use the principle of least privilege .
