Study Notes
Information Classification and Data Protection
- The main goal of information classification is to define protection requirements for sensitive data.
- Data classification is based on its value to the organization, particularly the potential negative impact from unauthorized access.
- Sensitive data includes personally identifiable information (PII), protected health information (PHI), and proprietary data; data posted online is generally not considered sensitive.
Data Handling and Media Management
- The most critical aspect of marking media is its classification, which informs users about protection measures needed.
- To re-use classified media in a less secure context, media should be purged, meaning all data is irrecoverably overwritten.
- Sanitization methods may be flawed due to improper execution by personnel, impacting data security.
Data Deletion Techniques
- Purging solid-state drives (SSDs) is the most reliable method for data destruction; random data is used to overwrite existing information.
- Physical destruction is the most secure way to delete data on optical media like DVDs, while erasing or formatting typically does not fully eliminate data.
Roles in Data Management
- Administrators assign data access permissions, while custodians back up data and protect its integrity.
- Rules of behavior, established by data owners, dictate appropriate use and protection measures for data.
Data Protection Regulations
- Under EU Data Protection law, a data processor processes personal data on behalf of a data controller, who directs the processor's actions.
Privacy Principles
- The Safe Harbor principles emphasize notice, choice, onward transfer, and access, all crucial for data privacy maintenance.
Security Control Implementation
- Tailoring security controls to fit organizational needs ensures resources are not wasted on irrelevant controls.
- It is essential to use secure offsite facilities for sensitive backup media to protect against theft while maintaining availability.
Incident Response and Prevention
- Marking backup tapes before they are sent to cost-effective storage can raise awareness of their sensitivity, reducing theft risk.
- Adhering to record retention policies is vital for ensuring backups do not hold data longer than necessary, which was not complied with in a given scenario.
Overall Best Practices
- Effective data protection involves thorough classification, reliable destruction methods, proper personnel training, and adherence to regulations and guidelines for handling sensitive information across various environments.
