Working with data and more specifically protecting it is the sole objective of an Ethical Hacker or a Cyber Security Professional. There are three major types of data that exist in today’s world, so let us understand them in brief…

PUBLICLY AVAILABLE DATA

The data publicly available to all is known as Publicly Available Data. For example, A bank’s balance sheets, insurance policy details, a government tender notices and job posts held by authorities.

CONFIDENTIAL DATA

When data is available only to the people involved in a process or an organization and is restricted from authorized access, it is known as Confidential Data. For example, a manufacturing company’s market forecast data, test cases and standards, a bank’s customer data consisting of the addresses and phone numbers or government sensitive scientific and medical research data.

RESTRICTED DATA OR PRIVATE DATA

When the data is super sensitive, in other words, data leakage might lead to serious issues, it is called Restricted or Private Data. Examples are a company’s system designs and trade secrets, financial account pin numbers, an email password, personal reports or medical reports.

CONCLUSION

If data like pin numbers, company’s trade secrets, bank’s customer data were to fall in wrong hands, it could compromise the security of the organization and also the privacy of those involved. Hence, protecting these sensitive information sources with the help of the various methods in information security is crucial.
