Certified Cybersecurity Technician Exam 212-82 Identification, Authentication, and Authorization Types of Authentication: Smart Card Authentication & Smart card is a small computer chip device that & s ° o ° o amm holds a users’ personal information required to authenticate them Users have to insert their smart cards into the card reader machines and enter their personal identification number (PIN) to authenticate themselves A c Smart card authentication is a cryptography-based authentication and provides stronger security than password authentication Copyright © by E L All Rights Reserved.

Smart cards can store password files, authentication tokens, one-time password files, biometric templates, etc. This technology is used with another authentication token, thus providing a multifactor authentication. This enables an efficient logical access security. This technology is applied in VPN authentication, email and data encryption, electronic signatures, secure wireless logon, and biometric authentication. A smart card consists identification. These identification number card. Smart cards also of a small computer chip that stores cards are inserted into a machine (PIN) is inputted for processing the help in storing public and the private personal information of the user for for authentication and a personal authentication information on the keys. Smart card authentication is a cryptography-based authentication and provides stronger security than password authentication. The main advantage of using a smart card is that it eliminates the risk of credentials being stolen from a computer as they are stored in the card’s chip itself. However, only a limited amount of information can be stored in the card’s microchip. Advantages of smart cards: = Highly secure technology: The smart card technology uses efficient encryption authentication methods, thus increasing the security of the card. = Easy to carry: Smart cards are easy to carry and a user simply needs to know the PIN of the card.

Disadvantages of smart cards: = Easily lost: Since smart cards are small in size, the chances of losing them are very high. = Security issues: Losing a smart card puts its owner’s information and identity at great risk. = High cost of production: As smart cards technologies; their production cost is high.

The SSO stores the credentials of a user in an SSO policy server. An example of SSO is Google applications. Users can access all Google applications using a single user name and password combination. Consider Google as a central service. This central service creates a cookie for all users logging in for the first time in any of the applications present in the central service. When the user attempts to access other applications of the central service, it eliminates the need for the user to enter the credentials again due to the cookie which has already been created. The system checks the credentials using the created cookie.

Disadvantages of SSO: = Losing credentials has a high impact as all the applications of the central service become unavailable. = There are many vulnerability issues related with the authentication for all the applications. = |tis an issue in multiuser computers and requires the implementation of certain security policies to ensure security.
