Security from the first design decisions

Define access

Separate roles and restrict each permission to actual needs. Authorisation must be checked on the server.

Minimise data

Collecting less data makes protection simpler. A defined purpose and retention period help keep a system understandable.

Handle failure

Validate input, limit attempts and avoid exposing internal details in error messages. These are foundational measures.

Maintain over time

Dependencies, access and backups need ongoing attention. Security is a continuous practice, never an absolute guarantee.
