Information Security Guide
Information security is the practice of preventing unauthorized access to information. It also prohibits the disclosure, modification, disruption, inspection, recording, use, and destruction of information. The balanced protection of the confidentiality, integrity and availability of data is the primary focus of Information security. It also maintains a focus on efficient policy implementation without hampering the organization’s productivity. This is largely achieved through a multi-step risk management process where it diagnoses threat sources, potential impacts, assets, and possible controls along with the effectiveness of the risk management plan assessment. The academics and professionals work combined together to set the policies, basic guidance, and industry standards to standardize this discipline. They were Information security are set on antivirus software, encryption software, firewall, and password.

Step 1: The main purpose of information security is to establish effective information security management (ISM) practices.
Step 2: Its design is achieved from the objectives and practices suggested by standards, reports, and literature.
