the term has become a global village is more realistic than fiction after the widespread use of the Internet in every country in the world. what the Internet is not effective computerization of the world. Like many other things, the Internet offers both good and bad. the consensus is that much of the good things the bad things. But the questions are related to serious data security. As more and more facilities, such as military, diplomatic and financial institutionsProcess, based on the Internet or other network for transferring data and streamline the number of people who try to abuse of such data, which is also increasing. This is different to avoid security measures data from the network managed to be accepted. most measures of data security in relation to software applications. Options computer hardware network security are also used.
To understand the importance of data securityConsider the case of a bank with branches throughout a country. To simplify this, most banks to set up a private network or a network connected to the Internet from one to transfer data to financial statements. A person with sufficient knowledge of software and hardware, networks may enter without permission and change according to his will. These people are called hackers. in the case of a bank as a data change means change or loss of money,Implementation of the state of enhanced security measures for the protection of data is absolutely necessary.Hardware technology used in network security.
The hardware components required for network computers with network cards and nods to connect these computers together through a physical connection such as cable or satellite electronic signal. you should also network and database management software for the effective functioning of the network. in most networksMode, a computer, server, known as the acts, a source other computers and act as a nod to this central computer.
usually, there are security measures designed to prevent unauthorized persons to access the network. Precautionary measures Such as software firewalls, anti-virus and anti-hacking software packages and encryption technologies Have been used very much. Such systems are necessary to prevent data theft and other malicious intentions.the problem with software packages for network security is that packets of this period, especially after it becomes obsolete. To understand hacking in general, as software packages for a certain period.
Thus, the computer security hardware device is a better choice to make. top manufacturers of network router hardware firewall provides contract for both types of network systems: Ethernet and wireless. the firewall settings canslightly modified. some companies also offer virtual private network devices for network security. But the most important to provide watertight protection for the network is that you must constantly upgrade hardware and software requirements.
