Data Classification and Security Policies

Information Classification in Organizations

• The primary purpose of information classification is to ensure the confidentiality, integrity, and availability of information by categorizing it according to its level of sensitivity and potential impact if compromised.

Classification Schemes

• Classification schemes are determined by the organization's information security policies and requirements.
• Examples of classification schemes used by organizations include:
  • Confidential
  • Internal Use Only
  • Public
  • Top Secret
  • Secret
  • Unclassified

Importance of Data Classification

• Data classification is extremely important because it helps protect sensitive information from unauthorized access, use, disclosure, disruption, modification, or destruction.

Classification Policies

• Classification policies describe how to label and handle information based on its classification level.
• Policies outline the procedures for accessing, storing, and transmitting classified information.

Labeling Requirements

• Labeling requirements ensure that classified information is properly marked and labeled to prevent unauthorized access or disclosure.

Encryption

• Organizations should use strong encryption to protect sensitive information from unauthorized access or interception.

Types of Information

• Organizations may handle three types of information classified by external groups:
  • Public Information
  • Sensitive But Unclassified (SBU) Information
  • Classified Information

Secure Disposal

• Secure disposal of sensitive information is important to prevent unauthorized access to information stored on devices or media.
• Deleting files or formatting a hard disk is insufficient for removing all traces of data from a device.

Standard Labeling Practices

• Using standard labeling practices for sensitive information ensures that classified information is properly identified and handled.
