Cyber Security

“Basics of cyber security” is an important topic in UPSC Civil Services (Main) Exam General Studies – paper III (Technology, Economic Development, Bio diversity, Environment, Security and Disaster Management). Here we present some basic points on cyber security.

Cyber security

Cyber security is the body of technologies, processes and practices designed to protect networks, computers, programs and data from attack, damage or unauthorized access. In a computing context, the term security implies cyber security. According to a December 2010 analysis of U.S. spending plans, the federal government has allotted over $13 billion annually to cyber security over the next five years.

Ensuring cyber security requires coordinated efforts throughout an information system. Elements of cyber security include:

  • Application security
  • Information security
  • Network security
  • Disaster recovery / business continuity planning
  • End-user education

One of the most problematic elements of cyber security is the quickly and constantly evolving nature of security risks. The traditional approach has been to focus most resources on the most crucial system components and protect against the biggest known threats, which necessitated leaving some less important system components undefended and some less dangerous risks not protected against. Such an approach is insufficient in the current environment.
