Authentication In Network Security

In this article, we will be talking about authentication in network security and the methods that can be used.


No one is surprised by the occasional weak links and glitches in the modern-day world of computing. Computers are among the most vulnerable and easily targeted setup of the technological world, being the reason for network security protocols putting so much effort into identifying users trying to gain access to networks. The process of recognizing the user does not necessarily lead to a discovery of the users’ identity. Still, it determines if the user is permitted and has the authorization to gain access to the resources. This is the purpose of Authentication in network security. Given the premise that advancement in technology also gives cyber-terrorist more tools to work with to advance their cause, it has become more challenging to keep up with their speed in acquiring advanced knowledge of systems. Hence, the implementation of more sophisticated means of authenticating users is at the forefront. 

Authentication Methods To Be Used

Defeating cybercriminals presents a few authentication methods that can be utilized for network security, some of which include;

Biometrics for Network Security: in simple terms, biometric refers to ‘measuring life.’ Biometrics can also be defined as the use of documented visible attributes of a user to authenticate the validity of their identity. This is a smart strategy since it is humanly impossible for two people to have the same physical attributes. Fingerprint identification, retinal and iris scan, as well as voice recognition, are some conventional biometric authentication methods currently used globally. The disadvantage of this form of Authentication is its requirement for specialized scanning equipment, which is not approved for specific industries and is generally expensive. 

Token Authentication: a token is any form of technical material used to gain controlled access to secure systems. RFID chip and dongle are popular forms of a token. With a token, it becomes difficult for hackers to access a secure account given that they will require enormous credentials and likewise the tangible device which will prove more challenging to obtain. 

Multi-Factor Authentication: this is an authentication process designed to request two or more independent identification means before granting access to the user. A good example includes a material that the user possesses, such as a phone number or physical token, biometrics, or something the user should know, such as a password. An excellent example of Multi-Factor Authentication is Automated Teller Machines, since it requires a card, a physical token, and a pin, something the user knows.
