The most types of data security are as follows:

  • Data Backup
  • Firewall
  • Data Encryption
  • Use Strong Password
  • Use Antivirus Software
  • Secure Your Computer
  • Up to Date Operating System 
  • Digital Signature
  • Educate Your Employees
  • Careful Use of Email and Website
  • Data Masking

Different Types of data security in Computer System

1. Data Backup

A data backup process is a most important types of data security measures which copying or archiving data files for the purpose of being able to restore data in case of data loss event. It is secondary storage of data which is used for data protection.
