Hacking & Network Security: What Is It Exactly (For Noobs)

It is not strange to call this generation as “intelligent” generation, the era of computers & internet. Humans are connected to each other through the world of computers spread over a network.
Essentially, in technical language, Computers communicate with each other through network. So any data communication between 2 or more computers involves transfer, sharing of vital data. The basic idea of networks is allow people remote access to geographically distant resources without having to be physically present. It has also been designed to send data back and forth, to stay connected.

There are large networks and small networks, but size is irrelevant in terms of importance of network security. The purpose of network security, quite simply, is to protect the network and its component parts from unauthorized access and misuse. Networks are vulnerable because of their inherent characteristic of facilitating remote access. For example, if a hacker wanted to access a computer not on a network, physical access would be vital. However, with networks in the picture, it is possible to bypass that particular security aspect. Therefore, it is vital for any network administrator, regardless of the size and type of network, to implement stringent security policies to prevent potential
losses.

The networks are computer networks, both public and private, that are used every day to conduct transactions and communications among businesses, government agencies and individuals. Today, most companies’ host computers can be accessed by their employees whether in their offices over a private communications network, or from their homes or hotel rooms while on the road through normal telephone lines.

Network security involves all activities that organizations, enterprises, and institutions undertake to protect the value and ongoing usability of assets and the integrity and continuity of operations. An effective network security strategy requires identifying threats and then choosing the most effective set of tools to combat them. Often important data is transferred from one computer system to other over the network. Network security safeguards the data communication so that vital information data is secured.

Whenever the word network security appears, it appears in conjunction with another popular buzzword “Ethical hacking”. The word “ethical” has special meaning as ethical hacking is very closely related to network security & is simply the use of programming skills to determine vulnerabilities in computer systems. Performed by special computer programming experts or hackers, it is very vital for the computers connected over network. With increasing use of the Internet and concerns about its security, especially when it comes to things like consumer information or private medical details, there is considerable need for computer experts to work in ethical hacking.

This is the guest post & Following is the Author Bio : Internet hacking is accessing a secure computer system by disabling or bypassing the security through internet. There are many ethical hacking tutorials available with which one can learn the ways of detecting the loopholes in cyber security.
