Study Notes
Data Ownership and Classification
- Data owners are responsible for defining classifications and ensuring proper labeling and protection of data.
- They establish requirements for protecting data at various classifications, such as encrypting sensitive data both at rest and in transit.
- Data classifications are typically outlined in security or data policies.
Types of Sensitive Information
- Personally identifiable information (PII) identifies individuals, while protected health information (PHI) pertains to health-related data linked to a specific person.
- Unauthorized disclosure of classified information results in a loss of confidentiality.
- Sensitive information must be marked, handled, stored, and destructed post-use to be properly managed.
Data Management Policies
- Record retention policies dictate the retention and destruction of data as per regulatory requirements or organizational policies.
- System owners are responsible for the systems that process data, while business and mission owners ensure system effectiveness.
Roles in Data Handling
- A data processor is typically a third-party entity handling organizational data.
- System administrators grant data access based on data owner guidelines.
- Users access data to perform tasks, while data custodians manage the daily protection and storage of data.
Security Controls and Compliance
- The GDPR emphasizes two key security controls: encryption and pseudonymization.
- Security control baselines serve as a reference for applicable controls within an organization.
Due Care vs. Due Diligence
- Due care involves management providing resources for effective job performance; due diligence refers to the execution of that job with those resources.
Data Protection Techniques
- Anonymization removes identifiable data elements, making original subject identification impossible and is challenging due to data inference.
- Metadata refers to data that describes other data.
Data Lifecycle Management
- Data Lifecycle Control encompasses processes like specification, modeling, database maintenance, audits for effectiveness, and backup archiving.
- Data protection must span three states: at rest, in transit, and in use.
Data Remanence
- Data remanence refers to residual signals after data is erased; countermeasures include clearing, purging, and destruction.
Information Classification and Categorization
- Information classification determines access privileges, while categorization assesses the impact of confidentiality, integrity, and availability (CIA) loss.
Privacy Requirements
- The Privacy Shield framework outlines requirements for Notice, Choice, Onward Transfer, Security, Data Integrity, Access, and Enforcement, applicable in the US and EU.
Legislative Standards
- HIPAA stands for Health Insurance Portability and Accountability Act.
- PCI (Payment Card Industry) is an industry standard for card transactions; non-compliance may hinder credit card acceptance for businesses.
Data Protection Techniques
- The most effective control for data at rest is the encryption of all mobile and removable devices.
- WPA2 is the most secure wireless network encryption protocol compared to WEP and can also incorporate VPN protections.
