A network links two or more computer components together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. Utilities such as the Internet, printers, scanners, and computers can be connected.

A network lets you transfer files, pictures, and information without using any kind of disk or external drive. Most businesses decide to use a network because they have more than one computer and want to share information and computer components.

No matter how tight your controls, there still may be a breach of security. Additionally, there are disasters beyond your control, such as fires, floods, or even simple power outages. Therefore, you will need a plan to recover data when such a disaster strikes.

The first step in coming up with a recovery plan is to list possible risks that could threaten your system and then rank them in the order of likelihood.

An Information Security Management System (ISMS) is a set of policies concerned with information management. The key concept of ISMS is for an organization to design, implement and maintain processes and systems for effectively managing information accessibility, thus ensuring the confidentiality, integrity and availability of information assets and minimizing information security risks. All training, implementation of anti-virus software, firewalls, and laptop safety policies fall under ISMS.
