The computer era has undergone revolutions so rapidly that the number of applications has exceeded the number of users who implement them and make the complex functions quite easier to do. In-fact, there has been a tremendous increase in the number of computers that almost every household is furnished with a minimum of two or more computers. Offices today can easily provide an individual system to each of their employee whether it is required in their job function or not. The fact that, in most of cases, there is generally more than one system available within same establishment, calls for the proper computer networking, a network technician, and obviously appropriate network security, in order to provide security against threats and significant data theft.
To establish a link in the group of computers within a particular space, one can make use of several approaches. You can easily find some simple and cheap as well as complicated and expensive options. The variation in options depends on the way in which PCs are interconnected and also the way they are connected to modem. Most of the Internet Service Providers will recommend connecting the modem to a central hub where individual PCs can be linked through the use of network cables. This might be a simple option if you won’t consider the additional expenses of configuring individual IP addresses every month, which is quite high.
An experienced network professional will suggest you the cheaper means of networking without any sort of monthly charges on it. However, he will also ensure the essential adjustments for improving the network security and to make it impervious towards the malicious programs in the form of malware and restrict the access of any hacker on your confidential information.
Basically, there are two types of security that should be installed by your network technician including information security and network security. Information security refers to the protection of data from malware and hacker attacks, or due to the mistakes of employees working in the organization. Such sort of security is restricted to inner boundaries of the network. Network security is used on a larger scale and is responsible for preventing the loss of data that belongs to the network from being placed in the wrong hands. It establishes a boundary around the network against all the external sources.
Network security starts functioning as soon as a user enter into the network, by authenticating him/her before permitting access to the sensitive information belonging to a particular network. Authentication varies from network to network on the basis of security level required. It can be one-factor, two-factor or three-factor security. Following to the type of authentication, the technician can move ahead for installation of firewall that prevents unauthenticated users from accessing the information. Blocking of disastrous virus programs can also be done with anti-virus software. Based on the requirement, network technicians will install appropriate software for ensuring complete security.
Therefore, it is imperative that you have proper network security measures for transferring critical data over internet.Tags:
