List and describe the authentication methods businesses use to protect their information both internal and externally when transmitted to outside parties? Solution Please let me know if you need more information:- when we say authentication first we need to protest the resources involved in our BUSINESS:- our business needs should be like:- 1. we must keep avoiding unauthorized persions from accessing the resources. 2. we just limit resources[data] to access the BUSINESS involved persons what they are not needed. [ just providing access to what they really needed ] To gain the above :- we can follow many methods which are available :- 1.logon authentication here we will be providing the username and password to the user/resorce to gain access to our business data.based on userid we can limit the data too. 2.network authentication based on network type which resource connected we can revoke the connection to our business network 3.remote authentication here remote authentcation will be involed in again username along with some security features [RSA, OTP ..etc]. 4.biometric authnetication based on the resource physical presence of finger print / ratina ..etc scans we will be authenticating the resources involved in business 5.smart card authentication. when we give access to our business resources/outside we should be maintainging the encryption technology to keep our data safe. when we mention outside we should be able to make our data not understandble till it reaches to our destination[resources] by using encrytption . Thanks.
