Online Authentication homework help
What is authentication?
Authentication is the process of determining whether someone or something is, in fact, who or what it says it is. Authentication technology provides access control for systems by checking to see if a user’s credentials match the credentials in a database of authorized users or in a data authentication server. In doing this, authentication assures secure systems, secure processes and enterprise information security. The students who are assigned with the Authentication assignment would through the stress of writing the assignment due to lack of time or knowledge.

The write-up would help you secure A+ grade and impress the professors.
Why is authentication important in cybersecurity?
Authentication enables organizations to keep their networks secure by permitting only authenticated users or processes to gain access to their protected resources. This may include computer systems, networks, databases, websites and other network-based applications or services.
After logging in, users can be further authorized for access to specific resources and systems only through the use of PCA tokens and other protocols that meet security requirements. A user can be authenticated but not be given access to a specific resource if that user was not granted permission to access it.
How does authentication work?
Authorization data stored in a database of authorized users’ credentials is compared to each user’s authenticated credentials during authentication. If the credentials entered match those on file and the authenticated entity is authorized to use the resource, the user is granted access. User permissions determine which resources the user gains access to and also any other access rights that are linked to the user, such as during which hours the user can access the resource and how much of the resource the user is allowed to consume.
Traditionally, authentication was accomplished by the systems or resources being accessed. For example, a server would authenticate users using its own password system, login IDs, or usernames and passwords.
What is authentication used for?
User and process authentication are used to ensure that only authorized individuals or processes are allowed to access company IT resources. Depending on the use cases for which authentication is used, authentication can consist of either SFA, 2FA or MFA.
The most common implementation of authentication is SFA, which requires a user ID and a password for sign-on and access. However, since banks and many companies now use online banking and e-commerce to conduct business and store customer Social Security and credit and debit card numbers, there is an increased use of 2FA and even MFA, which requires users and customers to enter not only a user ID and password, but also additional authentication information.
From an IT standpoint, organizations use authentication to control who has access to corporate networks and resources, as well as to identify and control which machines and servers have access. Companies also use authentication to enable remote employees to securely access their applications and networks.
Similarly, fingerprint scanning and biometric security technologies often provide the same level of security as single sign-on authentication. These techniques can allow one-time access to multiple systems with a single login.
What are authentication factors?
Currently used authentication factors include the following:
- Knowledge factor. Anything that is obtained from an output text with human verified information information.
- Possession factor. The possession factor, or something you have, may be any credential based on items that the user can own and carry with them, including hardware devices, like a security token or a mobile phone used to accept a text message or to run an authentication app that can generate a one-time password (OTP) or PIN.
- Inherence factor. The inherence factor, or something you are, is typically based on some form of biometric identification, including fingerprints or thumbprints, facial recognition, retina scan or any other form of biometric data.
- Location factor. Where you are may be less specific, but the location factor is sometimes used as an adjunct to the other factors. Location can be determined to reasonable accuracy by devices equipped with the Global Positioning System or with less accuracy by checking network addresses and routes.
Despite being used as supplemental authentication factors, user location and current time by themselves are not sufficient, without at least one of the first three factors, to authenticate a user.
Authentication vs. authorization
Authorization includes the process through which an administrator grants rights to authenticated users, as well as the process of checking user account permissions to verify that the user has been granted access to those resources. The privileges and preferences granted for an authorized account depend on the user’s permissions, which are either stored locally or on an authentication server. The settings defined for all these environment variables are established by an administrator.
What are the different types of authentication?
Authentication methods include the following:
- 2FA. This type of authentication adds an extra layer of protection to the process by requiring users to provide a second authentication factor in addition to the password. 2FA systems often require the user to enter a verification code received via text message on a preregistered mobile phone or mobile device, or a code generated by an authentication application.
- MFA. This type of authentication requires users to authenticate with more than one authentication factor, including a biometric factor, such as a fingerprint or facial recognition; a possession factor, like a security key fob; or a token generated by an authenticator app.
- OTP. An OTP is an automatically generated numeric or alphanumeric string of characters that authenticates a user. This password is only valid for one login session or transaction and is typically employed for new users or for users who lost their passwords and are given an OTP to log in and change to a new password.
- Three-factor authentication. This type of MFA uses three authentication factors — usually, a knowledge factor, such as a password, combined with a possession factor, such as a security token, and an inherence factor, such as a biometric.
- Biometrics. While some authentication systems depend solely on biometric identification, biometrics are usually used as a second or third authentication factor. The more common types of biometric authentication available include fingerprint scans, facial or retina scans, and voice recognition.
- Mobile authentication. Mobile authentication is the process of verifying users via their devices or verifying the devices themselves. This enables users to log into secure locations and resources from anywhere. MFA can be made biometric or OTP based. Biometric authentication is a less cumbersome system and is the more common approach. OTP is a more micropayment based method of authentication. Both require you to input a different code after using your device for some time.
- Continuous authentication. A much easier and faster way to authenticate users on your mobile device is through facial recognition. This allows you to easily accept new accounts without manually biasing the bank of sorts.
- Application programming interface (API) authentication. Open Authentication (OAuth) offers an alternate authentication mechanism for APIs, which is where the client authorization happens. This is achieved by using the OAuth protocol to access information about your API
