Introduction of Cyber Security

 

For most people, cybersecurity is the same in meaning to information security. This, however, is not true, as we will establish in this lesson. Cybersecurity is the ability to protect or defend the use of cyberspace from cyber-attacks. To better understand this definition, we first need to understand what cyberspace and cyber-attacks are.

Cyberspace may be a global virtual environment, totally on the web, created by computer systems. A cyber-attack is an attempt to disrupt, disable, destroy, or maliciously controlling a computing system via cyberspace to destroy the integrity of data or steal access-restricted information.

Therefore cybersecurity is about the protection of sensitive information, specifically those stored or accessed via the Internet, from cyber-attack.

Difference between Cybersecurity and Information Security

Information security is the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction to provide confidentiality, integrity, and availability. The information to be protected can reside on the Internet, a Local Area Network (LAN) or Wide Area Network (WAN), computer, or mobile computing device.

If you have information secured on a LAN that is not connected in any way to the Internet, only information security applies, not cybersecurity. Cybersecurity comes into play when security measures are implemented through cyberspace. Cybersecurity is a subset of the larger field of information security.

 

Principles of Cybersecurity

When implementing cybersecurity, there are two specific goals to be attained: first, the tip must be kept out of reach of potential cyber attackers and other unauthorized individuals. Second, cybersecurity measures must not hinder authorized users’ access to knowledge. the subsequent are the three main principles of cybersecurity.
