الموضوعات المخطط لها

• Least privilege: give each user, service, and database account only the access it needs.
• Defense in depth: several layers, so one failure is not a breach.
• Example layers: authentication, authorization check, validation, database permissions, logging.
• Do not rely on a single check, such as a hidden button in the UI.
• Review defaults: new accounts start with the lowest role.
