Keep the NAS up-to-date
System integrity and a process for keeping your NAS up-to-date are crucial to NAS security. Like a regular server, most NAS systems run an OS, such as EMC Corp. Celerra Data Access in Real Time (DART), Network Appliance (NetApp) Inc. Data Ontap or Microsoft Windows in the case of Windows Storage Server (WSS) 2003.

Many of the flaws are never noticed or aren't relevant to security, but the ones that can be used for exploits can make your NAS storage vulnerable.
