* Sniffing: Sniffing is the act of intercepting TCP / IP packets as they are transmitted at the beginning of a network. The monitoring is usually done by simply listening to a pirate.
Computer Systems Security
Security hardware and its components is also necessary for the comprehensive protection of data.

Information on the computer and data security
It is important to avoid loss of data and information in the case of hard disk crash. The only solution is to make regular backups of all data to other media such as cassettes, CD-ROMs, etc. It is good practice to keep external storage media for hard disk failure, restoring data from backup media on the new disc. In the event backup media is not affordable, try to save files on at least two different media. These media devices should systematically in a place that is safe, that information can be kept confidential. Personal database files usually backup files, tables, and large documents. As the technical constraints are still there, it is preferable to perform regular backups to prevent loss of information.
It is important to make a register of consultants, technical support and software documentation on how to keep manuals available to employees of the company.
