Public documents Data Classification Data classification is the process of assigning sensitivity levels to data while the data are being generated, modified, saved, or passed over an information system. Data are a critical business asset; the protection of the confidentiality, integrity, and availability of data is important for business operations and market competitiveness. Data classification provides organizations a sense of data criticality and the level of security needed to be implemented for different types of business data. While some business data need to be stored and processed only within the organization, other information may be required to be distributed to related third parties. Therefore, confidential and sensitive data must be protected from being exposed. The sensitivity and importance of information determine how confidential it is and how it should be separated from the rest of the data. Data can be classified into five different levels as follows. 1. Top secret: This level includes highly sensitive information such as business plans and financial records. Exposing or leaking such information may cause severe damage to the organization’s assets and reputation, further leading to legal consequences. 2. Highly confidential information: This level includes confidential information such as corporate or customer data such as bank-account details, credit-card details, and social security numbers. Exposing this information can invite financial or legal risks to the organization. Only the authorized personnel can access this information. 3. Proprietary information: This level includes confidential internal information such as customer and employee reviews, third-party details, and technology upgrades of a new Module 15 Page 1757 Certified Cybersecurity Technician Copyright © by EG-Gouncil All Rights Reserved.

It is an important component of security compliance programs that protect unauthorized access to confidential information. Data Encryption Protecting information by transforming it so that it becomes unreadable for an unauthorized party. It safeguards corporate secrets, classified information, and personal information. The encrypted data cannot be read by any unauthorized persons or entities. Data Masking Protecting information by obscuring specific areas of data with random characters or codes. Data masking protects sensitive data such as personally identifiable information, protected health information, payment card information, intellectual property, etc. Apart from this, data masking also protects against an insider threat. Implementing data masking will bolster the security strategies of an organization. Data Resilience and Backup Making a duplicate copy of critical data to be used for restoring and recovery purposes when the primary copy is lost or corrupted, either accidentally or on purpose. Data resilience allows the data to remain available to the applications if there is any failure in the hosted data. Retaining multiple copies of a data backup help in restoring the data with ease and mitigate the risks of data corruption or malicious attacks.
