    Study Notes

    Information Asset Security

    • Information assets are valuable to any organization.
    • Organizations use information to fulfill their mission or goal.
    • The information asset security domain is the collection, handling, and protection of information throughout its lifecycle.
    • Information classification is a primary step in information asset security. It categorizes information by its sensitivity to disclosure.

    Information Classification

    • Classification systems are labels that assign a sensitivity level to information.
    • Commercial classification systems can be less complex than government systems, and are often customized to fit the business's specific needs.
    • Common criteria to consider when classifying information include:
      • Whether the information is not public knowledge or public domain.
      • Information that has specific value to the organization.
      • Information that needs to be protected from unauthorized access.
      • Information subject to government regulations.

    Data States

    • Data can exist in three states: at rest, in transit, and in use.
      • Data at rest is stored on devices or media.
      • Data in transit is data transmitted over a network.
      • Data in use is data actively being processed by an application.

    Sensitive Information Handling

    • A Data Breach is an unauthorized entity's access to classified data.
    • Marking sensitive information helps users identify its classification level.
    • Storing sensitive data requires strong encryption, such as AES 256, to prevent unauthorized access.
    • Environmental controls, such as temperature and humidity controls, are essential to protect sensitive information.

    Destroying Sensitive Data

    • A Degausser uses magnetic fields to remove data remanence from magnetic storage media.
    • Degaussing is not effective for SSDs.
    • Multiple methods exist to sanitize media, including:
      • Erasing – simply deleting the data using a command.
      • Clearing – overwrites the data to prevent recovery using common tools.
      • Purging – a more intense form of clearing.
      • Destruction – complete elimination of the media.
      • Declassification – preparing media for reuse in an unclassified environment.

    Record Retention

    • Record retention involves keeping and maintaining important information as long as necessary.
    • Proper record retention is crucial for asset retention.
    • Legal and regulatory frameworks often dictate how long organizations must keep data, including specific periods like three years, seven years, or indefinitely.
    • The General Data Protection Regulation (GDPR) applies to organizations with European visitors, regardless of location.

    Ownership and Accountability

    • It is critical to define ownership and accountability for information and assets.
    • Clear roles and responsibilities ensure that personnel understand who is accountable for protecting data.
    • Information ownership roles include:
      • CISO: accountable for overall data protection.
      • Information owner: responsible for their information and security policies.
      • Information Custodian: oversees technical security controls.
      • Information steward: responsible for data analytics and business process support.
      • Information user: accountable for following data classification guidelines.

    Data Owner Responsibilities

    • The data owner is responsible for:
      • Identifying data classifications and ensuring it is appropriately labeled.
      • Implementing security controls based on the data classification and security policy.

    System Owner Responsibilities

    • The system owner, or asset owner, is accountable for systems that process sensitive data. They are responsible for:
      • Creating a system security plan.
      • Maintaining the security plan and ensuring systems operate according to requirements.
      • Providing security training to system users and support personnel.
      • Updating security plans when necessary.

    Business/Mission Owner Responsibilities

    • The business/mission owner is accountable for ensuring systems provide value to the organization.
    • This role is viewed differently between organizations, and responsibilities can overlap with system owner responsibilities.

    Information Asset Security

    • Organizations utilize information assets to accomplish their mission or goal.
    • Information Asset Security focuses on protecting information throughout its lifecycle.
    • Classifying information based on its value to the organization is a crucial step in information asset security.

    Protecting Information Assets

    • Protecting information assets involves both hardware and software security measures.
    • Application Service Providers (ASPs) offer a way to outsource applications, avoiding internal hosting and management.
    • Carefully evaluating ASPs for data protection safeguards is essential.

    Due Care vs. Due Diligence

    • Due Care involves reasonable steps to ensure safety and mitigate risks, adhering to standard practices.
    • Due Diligence goes beyond standard practices and involves a thorough investigation of potential risks and vulnerabilities.

    Information Classification

    • Information classification organizes information assets by their sensitivity to disclosure.
    • Classification systems use labels to identify sensitivity levels.
    • A nine-step information classification procedure defines the process.

    Government & Military Classification Systems

    • The government and military use four classification levels: Top Secret, Secret, Confidential, and Unclassified.
    • Unauthorized disclosure of classified information can result in severe consequences.

    Commercial Classification Systems

    • Commercial organizations often create their own classification systems tailored to their needs.
    • Commercial classification systems are typically less complex than government systems.
    • The complexity of classification systems often increases with regulatory requirements.

    Examples of Restricted Data

    • Personally Identifiable Information (PII) can be used to identify an individual.
    • Protected Health Information (PHI) relates to a specific person's health.
    • Proprietary data helps an organization maintain a competitive edge.

    Data States

    • Data at Rest refers to data stored on various media.
    • Data in Transit refers to data transmitted over a network.
    • Data in Use is data being processed by an application.

    Handling Sensitive Data

    • Preventing data breaches is a primary goal in sensitive data management.
    • Marking sensitive data helps users identify classification levels.
    • Encryption, environmental controls, and secure storage devices can protect data.

    Destroying Sensitive Data

    • Organizational policies should define data destruction methods based on classification.
    • Sanitization methods such as clearing, purging, and destroying ensure data recovery is impossible.

    Eliminating Data Remanence

    • Data remanence is residual data that persists even after erasure.
    • Degaussing can remove data remanence from magnetic media.

    Ensuring Appropriate Asset Retention

    • Record retention is crucial for maintaining essential information and destroying it when no longer needed.
    • Regulations often dictate data retention periods.

    General Data Protection Regulation (GDPR)

    • GDPR governs the collection and processing of personal information in the EU.
    • Websites attracting European visitors must comply with GDPR, regardless of location.

    Asset Ownership

    • The CISO is accountable for organizational data protection.
    • The information owner is responsible for their information and applying security policies.
    • The information custodian implements technical controls to protect assets.
    • The information steward ensures information supports business processes.
    • The information user is responsible for using information according to its classification.
