ABSTRACT

Governments, military, organizations, financial institutions, universities and other businesses collect, process and store a large amount of confidential information and data on computers and transmit that data over networks to other computers. With the continuous rapid growth of volume and sophistication of cyber attacks, quick attempts are required to secure sensitive business and personal information, as well as to protect national security. The paper details about the nature of cyberspace and shows how the internet is unsecure to transmit the confidential and financial information. We demonstrate that hacking is now common and harmful for global economy and security and presented the various methods of cyber attacks in India and worldwide.

1. INTRODUCTION

Cyber security is defined as technologies and processes constructed to protect computers, computer hardware, software, networks and data from unauthorized access, vulnerabilities supplied through Internet by cyber criminals, terrorist groups and hackers. Cyber security is related to protecting your internet and network based digital equipments and information from unauthorized access and alteration. Internet is now not only the source of information but also has established as a medium through which we do business, to advertise and sell our products in various forms, communicate with our customers and retailers and do our financial transactions. The internet offers lots of benefits and provides us opportunity to advertise our business across the globe in minimum charges and in less human efforts in very short span of time. As internet was never constructed to track and trace the behavior of users [1]. The Internet was actually constructed to link autonomous computers for resource sharing and to provide a common platform to community of researchers [1]. As internet offers on the one hand huge number of benefits and on the other hand it also provides equal opportunities for cyber-terrorists and hackers. Terrorist organizations and their supporters are using internet for a wide range of purposes such as gathering information and dissemination of it for terrorist purpose, recruiting fresh terrorists, funding attacks and to motivate acts of terrorism [2]. It is often used to facilitate communication within terrorist groups and gathering and dissemination of information for terrorist purposes [2].
