Answer: Explanation:
Salting alters the hash of a password so that it does not physically match the hash of another password. A salt and password are concatenated and processed with a cryptographic hash function. Salt prevents use of rainbow and hash tables to attacking and cracking passwords.
For example, a user has the password, "password000" and is put through a SHA1 hash. In the password database, all of the users with the password "password000" will have the exact same hash, because of the nature of hashing functions. So, if an attacker breaches the database and brute force the password of the user mentioned above, he could look for all the hashes that match the original user's and would know their passwords are also "password000".
By applying a salt, the password hashes would no longer be identical to one another, even though the actual password is still the same. This requires the attacker to go in and attempt to brute force the second password (which has a different salt), even though it may be the same as the first.
In conclusion, it prevents an attacker from uncovering one password and subsequently uncovering multiple others.
Tiered storage is an underlying principle of ILM (<span>information lifecycle management</span>). It is a storage networking method where data is stored on various types of media based on performance, availability and recovery requirements. For example, data intended for restoration in the event of data loss or corruption could be stored locally -- for fast recovery -- while data for regulatory purposes could be archived to lower cost disks.
