We can easily understand this thing by its name(confidentiality) which means that only confidential persons are allowed to access the data. It is one of the basic elements of information security. To ensure confidentiality one needs to use all the techniques designed for security like a strong password or network security key, encryption, authentication, and defense against penetration attacks.


Integrity means to prevent our data for unwanted changes or maintaining data in its correct state,  either accidentally or maliciously. There are many techniques where we can prevent our data to been modified and there are some tools also which can able to protect data integrity.


The term availability is somehow related to confidentiality where we make sure that your data is not accessible by unauthorized person but authorized persons can easily access it.

Availability in information security means matching network and computing resources to compute data access and implement a better policy for disaster recovery purposes.

Information security policies

Information security policy is a document that an enterprise draws up, based on its specific needs and quirks. It helps to establish what data to protect and in what ways. These policies guide an organization during the decision making about procuring cybersecurity tools. It also mandates employee behavior and responsibilities.

  • A statement describing the purpose of the infosec program and your overall objectives
  • Definitions of key terms used in the document to ensure shared understanding
  • An access control policy, determining who has access to what data and how they can establish their rights
