Challenge-response token authentication systems produce a challenge, or input for the token device. The most common variety is challenge-response tokens. Asynchronous Dynamic TokenĪsynchronous dynamic tokens are not synchronized with a central server.

This method uses strong authentication: the token is useless without the PIN, and the PIN is useless without the token. In both cases, users typically authenticate by typing their username, their PIN or password (something they know), and the dynamic token code (something they have). Once used, the token displays the second code, and the server also expects token code 2. Some operating systems themselves have ways for users to enable read-only modes on: A.Ĭounter-based synchronous dynamic tokens use a simple counter: the authentication server expects token code 1, and the user’s token displays the same code 1. There are many manufacturers of physical duplicators some indicate their capacity limitations and some can make more than just one A. In a field where expectations and standards can change case-by-case or person-to-person, you must establish an arsenal of many tools, especially: A.ĭepending on the situation and nature of the case you will have to make, the decision must be made to either leave the system on or power off to make a Forensic image of the: A. Unlike a Hard Disk Drive that stores data on the platter, Solid State Drives move data throughout its cells that are composed of: A.
