What do you understand by user identification?

Summary of the Article: User Identification and Authentication

User identification (user ID) is a logical entity used to identify a user on a software, system, website or within any generic IT environment. It is used to distinguish between the users who access or use IT-enabled systems. An example of user identification includes browser-based identification methods for users visiting web pages. User identification and authentication are closely related, where identification refers to uniquely identifying a user and authentication refers to proving one’s identity.

The process of verifying the identity of a user is called authentication. User-ID is important as it provides visibility into user activity and allows enforcing least privilege. It helps identify what users are actually doing on the network. User-ID serves two purposes – identifying the user on the network and identifying the IP addresses of the computers the user is logged into.

There are various forms of identification, such as a valid driver’s license, birth certificate, state-issued identification card, student identification card, social security card, military identification card, passport, or passport card. Authentication commonly involves three factors – knowledge factor (password), possession factor (mobile phone), and inherence factor (fingerprint).

Common types of authentication include password-based authentication, multi-factor authentication, certificate-based authentication, biometric authentication, and token-based authentication. Authentication is important in keeping networks secure by permitting only authenticated users or processes to access protected resources.

Questions:

1. What do you mean by user identification?

User identification (user ID) is a logical entity used to identify a user on a software, system, website or within any generic IT environment. It is used within any IT enabled system to identify and distinguish between the users who access or use it.

2. What is an example of user identification?

For example, a user visiting web pages in a web browser, either on a mobile device or computer, would be identified by browser-based identification methods. A user playing a mobile-app game on a smartphone or tablet would be identified by a mobile identifier.

3. What do you understand by user identification and authentication?

Identification is the ability to identify uniquely a user of a system or an application that is running in the system. Authentication is the ability to prove that a user or application is genuinely who that person or what that application claims to be.

4. What is the process of user identification?

The process of verifying the identity of a user is called Authentication.

5. What is the importance of user ID?

User-ID provides visibility into user activity in the environment and allows you to enforce least privilege – one of the fundamental security principles. In other words, once you have defined what people are allowed to do on the network, you will very quickly be able to identify what they are actually doing.

6. What are the two purposes of user ID?

The purpose of User-ID is to identify the user on the network and the IP addresses of the computers the user is logged into. User-ID can retrieve information from a connected LDAP directory server.

7. What are three examples of identification?

Valid Forms of ID: Valid Driver’s License, Birth Certificate, State-issued Identification Card, Student Identification Card, Social Security Card, Military Identification Card, Passport or Passport Card.

8. What are two examples of identification?

Identification can be a card or document serving to establish the identity of someone or something. For example, a driver’s license is accepted as identification. It can also refer to proof or evidence of identity.

9. What are the three common identification and authentication methods?

The three authentication factors are: Knowledge Factor – something you know, e.g., password. Possession Factor – something you have, e.g., mobile phone. Inherence Factor – something you are, e.g., fingerprint.

10. Which are the three ways of authenticating user identity?

Common authentication types include password-based authentication, multi-factor authentication, certificate-based authentication, biometric authentication, and token-based authentication.

11. Why is user identification and authentication important?

Authentication is important because it enables organizations to keep their networks secure by permitting only authenticated users (or processes) to access their protected resources, which may include computer systems, networks, databases, websites, and other network-based applications or services.
