Basics of cyber security

Cyber security is a process, technique or procedure to ensure information security goals.

Aim of Information Security is to provide CIA i.e.

  1. Confidentiality of information
  2. Integrity of information
  3. Availability of information


These 3 parameters (CIA) are called security goals/security services.

The other security objectives also include such other parameters as authenticity, authorisation, accounting and non-repudiation.


  • Cyber Security is the security of information and its communicating channels as applied to computing devices such as computers and smartphones, as well as computer networks such as private and public networks, including the Internet as a whole. The field covers all the processes and mechanisms by which computer-based equipment, information and services are protected from unintended or unauthorized access, change or destruction. Computer security also includes protection from unplanned events and natural disasters. Cyber security is a complex issue that cuts across multiple domains and calls for multi-dimensional, multilayered initiatives and responses.


  • The act of protecting ICT systems and their contents has come to be known as cyber security. A broad and debatable concept, cyber security can be a constructive term. It generally refers to a set of activities and other measures intended to protect from attack, disruption, or other threats to computers, computer networks, related hardware and devices software, and the information they hold and communicate, including software and data, as well as other elements of cyberspace.


  • Cyber security is also associated with the technical term, information security, which is explained in federal law as protecting information and information systems from illegal access, use, disclosure, disruption, modification, or damage in order to provide integrity, confidentiality and availability.


  • Integrity denotes to guarding against improper information modification or destruction, and includes ensuring information non repudiation and authenticity.


  • Confidentiality signifies preserving authorized restrictions on access and disclosure, including ways of protecting personal privacy and proprietary information.


  • Availability indicates ensuring timely and reliable access to and use of information. Cyber security concentrates on protecting computers, networks, programs and data from unintended or unauthorized access, change or destruction. Governments, military, corporations, financial institutions, hospitals and other businesses gather process and store huge confidential information on computers and pass on that data across networks to other computers. With the growing volume and complexity of cyber attacks, more attention is necessary to protect sensitive business and personal information, as well as protect national security.
