Authentication Servers as Key Protectors of Data Security

Faculty of Computer and Engineering – Hi, friend! Have you ever thought about how important it is to keep our data secure online? In an increasingly sophisticated digital world, this is becoming even more crucial. Imagine if your personal information fell into the wrong hands. It would be troublesome and potentially dangerous, right?

Here, I’ll discuss the importance of authentication servers. In the field of informatics, server authentication refers to the process of verifying users conducted by the server when users want to log into the system. This authentication process usually involves a username and password or a password that matches what was entered during the initial setup, and this information is stored in a database.

If the entered data matches the database, the user is granted access to the system. Conversely, if it does not match, the system denies the user’s access. The importance of an authentication server is like a fortress that ensures only the rightful individuals can access your account.

There are many types of authentication used today in the field of informatics. One example is two-factor authentication (2FA). This type of authentication is stronger than password-only authentication. How does this happen? Because the authentication process not only requires a password to access the system but also a special code sent to the user’s phone, known as a verification code. So, with two-factor authentication, even if the password is leaked, it is difficult to hack the system without knowing the code.

What is the purpose of an authentication server?

The role of an authentication server is to verify the identity of users accessing the system. It can also be used to restrict access to data through a security system, i.e., preventing users from logging in if the entered password is incorrect. Equally important, it protects user data from unauthorized access. With the prevalence of identity theft, account breaches, and general data theft in today’s world, authentication servers can be used to mitigate cybercrime.

Conclusion

It can be concluded that the importance of an authentication server is significant as it greatly aids the authentication process. In this increasingly advanced era, the issue of personal data security has become very important. The rampant data breaches make authentication one of the security systems that can safeguard the confidentiality of data and information within an account.

How an authentication server works:

When a client computer connects to a network, the authentication server asks for the user’s identity (username and password) to match the information in the authentication server database and then determines whether the user is allowed to use services on the computer network. If the authentication and authorization process is successful, a reporting process is conducted, recording all user connection operations, the duration of data transfer, and the amount of data transferred.

Examples of authentication servers

Examples of authentication servers include Radius Server, proxy servers with NCSA users, and Samba servers with authentication. The relationship between the function and operation of authentication servers is very close and mutually supportive, where authentication performed by the authentication server/user verification can support the implementation of information and network security.

Authentication methods:

  • Something You Know: This is the most common authentication method based on confidential information like passwords and PINs. It assumes that no one else knows the secret except you.
  • Something You Have: This usually acts as an additional factor that makes authentication more secure. It relies on unique objects like magnetic/smart cards, hardware tokens, USB tags, etc. It assumes that the object is not possessed by anyone else except you.
  • Something You Are: This method is rarely used due to technical and human factors. It is based on the uniqueness of your body parts that may not be shared with others, such as fingerprints, voice, or retina impressions. It assumes that body parts like fingerprints and retina impressions cannot be identical to someone else’s.
  • Something You Do: Every user does something differently. Examples include voice analysis (speech recognition) and handwriting analysis. Some common combinations of authentication factors include character generators using smart codes, used with smart cards and PINs or passwords.
