What is a Network Attached Storage

 

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. NAS [1] is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance – a purpose-built specialized computer.[nb 1] NAS systems are networked appliances which contain one or more storage drives, often arranged into logical, redundant storage containers or RAID.

Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers. Potential benefits of dedicated network-attached storage, compared to general-purpose servers also serving files, include faster data access, easier administration, and simple configuration.[2]

Disaster Management and Contingency

 

Summary and Value Proposition

 

Business continuity and disaster recovery (BC/DR) planning begins with a thorough risk assessment. Risk assessment is part of a larger risk management process found in most businesses. The four major components of the BC/DR risk assessment are threat assessment, vulnerability assessment, impact assessment, and risk mitigation strategy development.

 

In this article , we focus on threat and vulnerability assessment. In order to perform a thorough threat assessment, you need to look at threats and threat sources both internal and external to the company. It is often helpful to assess risk based on the potential risks to people, process, technology, and infrastructure.

People are not only the company’s employees but also its vendors, partners, customers,

and the larger community in which it operates. Processes are all the business

and IT processes used in the business. Processes are used to generate revenue, track

expenses, and manage operations from facilities management to human resources

and beyond.
