The computer age has developed so quickly that there are more applications to it than users to implement them and make complicated tasks much easier. The number of computers however, has increased tremendously thereby furnishing each household with at least two or more computers. Offices can easily provide advanced PCs for each of their workers whether their job requires it or not. The fact that in most cases there is usually more than one computer in the same establishment, calls for the networking of computers, a network technician, and of course proper network security, to provide security against hackers and sensitive data theft. To link up a group of computers in a given space, there are several approaches that one can use. Some methods are simple and cheap while others are complicated and involve high initial cost. The options vary with the way the PCs are connected to each other and to the modem. Internet Service Providers will mostly recommend linking the modem to a hub from which network cables can connect the individual PCs. This might be simpler if you ignore the additional monthly costs of configuring individual IP addresses for all the PCs, which can be quite expensive. A professional network technician will suggest cheaper methods of networking without involving any monthly charges. However, he will also take into account the necessary adjustments to improve network security and to make it resistant towards any virus in the form of malware and prevent the infiltration of any hacker on your private information. There are two types of security that have to be installed by the network technician, namely information security and network security. Information security is preventing loss of data by malware attack and hacker attacks, or due to mistakes of the members belonging to the organization. This type of security is restricted to the internal boundaries of the network. network security is worked on a larger scale and is responsible for protecting the data belonging to the network from being placed in the wrong hands of a hacker. It draws a boundary around the network against any outside sources. network security begins as soon as a user enters the network, by authenticating the user before he or she has access to any private information belonging to the network. Authentication can vary from network to network depending on the level of security required. Sometimes, for home networks, a username and password will suffice. This is one factor security. Two-factor security is the scanning of some object in your possession that can validate your identity, for example, a passkey, ATM card, security card, etc. Three-factor security will screen the person for some character that he or she possesses naturally. For example, retinal eye scans, fingerprint scans, etc, is three-factor authentication. Following the authentication, the network technician can further install a firewall to prevent unauthenticated users from gaining access to information they do not have the right to possess. Blocking of malware and Trojans has to be done by installing anti virus software or IPS systems. Depending on the requirement, network technicians will install the appropriate software to ensure that there is no threat towards your network under any circumstances.
