Chapter 3: Access Control - Other Identification Methods

There are a few methods is this section of the exam guide that are somewhat self explanatory and I have heard of them before. I want to elaborate on a few that I am not so familiar with or that I have never heard of before by definition. The first is a method known as password hashing. Salts are used in order to add more complexity to add more randomness to the process of encrypting the authentication technique. Hashing makes it a lot harder for a hacker to get to the correct format of the system that implements this technique of identification. Another technique that I have never had the chance use in a real life situation for authentication and identification are the use of cards to gain access to systems. There is one main difference here concerning cards. Memory cards cannot process information whereas smart cards can.
