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.

Purpose of Information Classification

• The purpose of information classification is to ensure that information is protected from unauthorized access, use, disclosure, disruption, modification, or destruction.

Classification Policies and Information Security

• Classification policies are related to information security in an organization, as they outline the procedures for accessing, storing, and transmitting classified information.

Security Categories

• The different security categories or classifications used by an organization are determined by the organization's information security policies and requirements.

Grouping Information

• Classification schemes typically group information based on its level of sensitivity and potential impact if compromised.

Strong Encryption

• Strong encryption helps protect sensitive information from unauthorized access or interception.

Classified Information

• Information classified by external groups includes Public Information, Sensitive But Unclassified (SBU) Information, and Classified Information.

Secure Disposal

• Secure disposal of sensitive information is important in an organization to prevent unauthorized access to information stored on devices or media.
