Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию. Token-Based Authentication

Preconditions:

В данной заметке рассматривается работа JWT с симметичным алгоритмом шифрования (HS256/HS384/HS512)

Основы:

Аутентификация(authentication, от греч. αὐθεντικός [authentikos] – реальный, подлинный; от αὐθέντης [authentes] – автор) - это процесс проверки учётных данных пользователя (логин/пароль). Проверка подлинности пользователя путём сравнения введённого им логина/пароля с логином/паролем, сохранённым в базе данных пользователей.

Авторизация(authorization — разрешение, уполномочивание) - это проверка прав пользователя на доступ к определенным ресурсам.

We are implementing database dumping which is straightforward but can be tedious to setup. Here's our setup:

1. Create AWS user for db backups (e.g. db-backups-{{app}})
   • Save credentials in a secure location
   • If adding db scrubbing, use a separate user (e.g db-scrubs-{{app}})
2. Create bucket for S3 access logging (e.g. s3-access-log-{{app}})
3. Create consistently named bucket for db dumps (e.g. db-backups-{{app}})
   • Enable logging to s3-access-log-{{app}} with prefix of db-backups-{{app}}
4. Add IAM policy for bucket access

• Select user -> Choose "Add inline policy"
