| DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity.
Usually, DoS attacks are assumed to be network related where the attacker floods the network with traffic that causes legitimate network traffic to be either slowed or blocked. For a storage device, a DoS attack can also occur when an attacker is able to make the data on the disks unreadable, thus unavailable, to the customer. This is a common attack used by ransomware where the attacker encrypts the data on the drives requesting payment for the unencryption key. By using data authentication keys, an attacker is unable to read or write data to the drives. It is also important to make sure the mode of the drives is set to full, otherwise only some of the data on the drive is protected. |
