Cyber security is the activity of protecting computers, servers, mobile devices, electronic systems, networks, and data from malicious threats. It is also referred to as information security or electronic information security. This term can be applied in various contexts and can be divided into several common types, as below:

• Application security: focuses on keeping software and devices free from threats. An infiltrated application may provide unauthorized access to the data it is designed to protect. Security should be started buiding from the design phase, before a program or device is deployed.
• Information security: protects the integrity and privacy of data, both during storage and transmission.
  
• Operational security: includes processes, regulations about handling and protecting data assets. The rights that users have when accessing the network and the procedures that determine how and where data can be stored or shared belong to the scope of this protection.
• Incident Recovery and Business’s continuity: determine how an organization responds to a cybersecurity incident or any other event that causes operational or data loss. Incident repair policies dictate how an organization restores its operations and information to return to normal functioning prior to the incident. Business continuity is the plan that organizations rely on when attempting to operate without certain resources.
• End-user education: resolves the most unpredictable cyber security factor: people. Anyone can accidentally introduce virus into a secure system if they do not conform to good security measures. Instructing users to delete suspicious email attachments, do not plug in unidentified USB drives, and other important lessons are crucial for any organization’s security.
