Access Control (ACL)

When is Basic Authorization used vs. Bearer Authorization?

  • The Basic authentication schemes are dedicated to the authentication using a username and a secret
  • The Bearer authentication scheme is dedicated to the authentication using a token

Basic authorization used when in sign-in process, after signing-up.

Bearer authorization used after basic auth done. for every request will use a bearer auth to verfiy if token match user token or not.

What does the JSON Web Token package do?

  • Defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

Generates a token that we can use with authorization and information exchange.

What considerations should we make when creating and storing a SECRET?

  • Use encryption to store secrets within .git repositories
  • Use environment variables
  • Use “Secrets as a service” solutions

don’t create a weak secret.

don’t store it in a plain text.

don’t share your secret with anyone.

don’t use same secret for different accounts.

Document the following Vocabulary Terms.

  • encryption :

is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format — called “cipher text.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the internet.

it is a process that convert our passwords to hashed ones, with characters representation. to make our passwords secured. we use the bcrybt library to do this.

  • token :

is a piece of a two-factor authentication security device that may be used to authorize the use of computer services.

it an encoded json, that we use in beare authorization to ensure if the user is authorized or not.

These non-human privileged credentials are often called “secrets” and refer to a private piece of information that acts as a key to unlock protected resources or sensitive information in tools, applications, containers, DevOps and cloud-native environments.

it is a signiture for the developper that make his token secure and no one can access his data when his secret is exists.

  • JSON Web Token :

is a proposed Internet standard for creating data with optional signature and/or optional encryption whose payload holds JSON that asserts some number of claims. The tokens are signed either using a private secret or a public/private key
