Authentication vs authentication vs authorization

What is the difference between authentication and authentication

All three terms are often used in connection with an application. Although they sound similar, they have different meanings. As they are closely linked and are often confused, we explain them in one entry.

What do authentication and authentication mean in detail?

Data transmission is not always guaranteed. Although it is guaranteed that the messages remain encrypted, the security of the encryption still depends on the protocol used. Although the encryption has not yet been cracked, hackers have managed to gain access to user data via other security gaps.

Who offers end-to-end encryption?

This now includes services such as Microsoft Teams, WhatsApp, Zoom, Telegram, etc. It is therefore very relevant for communication tools, as the messages remain encrypted on the way between sender and recipient.

Authentication

• Proof of identity
• In everyday life, for example by presenting an identity card
• On the Internet often through the combination of password and user name

Authentication

• Authentication refers to the verification of an identity card
• In everyday life by checking an ID card for forgery
• The Internet checks whether the combination of password and user name exists in the system

Authorization

• Grant access to privileges
• In everyday life, for example, access is granted to a company
• After authorization, you can work in a user account on the Internet

Do I have any points of contact with this in my professional life?

Yes, nowadays we encounter this issue on a daily basis. Be it when checking e-mails or visiting websites. For almost everything the Internet offers, identity is checked and corresponding privileges are granted.

What does that mean for me?

To increase your security, use encrypted connections. Passwords must be complex and unique. Don’t just rely on your password and user name. Use two-factor authentication wherever you have the option of using a physical hardware device such as the authenticator from REINER SCT.
