Data Classification Framework
All data must be classified according to sensitivity and regulatory requirements. The following classification levels establish handling, storage, and access requirements:
| Classification Level | Description | Examples | Handling Requirements |
|---|---|---|---|
| Level 1 β Public | Information approved for public release | Marketing materials, press releases, published reports | Standard access controls |
| Level 2 β Internal | For internal use only; limited business impact if disclosed | Internal memos, process documents, org charts | Employee-only access, no external sharing |
| Level 3 β Confidential | Sensitive data requiring protection; moderate impact if breached | Employee records, supplier contracts, internal financials | Encryption at rest, role-based access, audit logging |
| Level 4 β Restricted | Highly sensitive; severe regulatory, financial, or legal impact if compromised | PII, health records (PHI), payment card data, trade secrets | End-to-end encryption, MFA, strict access control, DLP monitoring |
Data Security Measures
The organization implements defense-in-depth security measures across all data classification levels. Technical, administrative, and physical controls are layered to minimize risk exposure.
Technical Controls
- Encryption: AES-256 encryption for data at rest; TLS 1.3+ for data in transit. Encryption keys managed through Hardware Security Modules (HSMs) or approved cloud key management services.
- Access Control: Principle of least privilege enforced through Role-Based Access Control (RBAC) with mandatory Multi-Factor Authentication (MFA) for all restricted data systems.
- Data Loss Prevention (DLP): Automated DLP solutions deployed across email, cloud storage, endpoints, and network egress points to detect and prevent unauthorized data exfiltration.
- Endpoint Protection: All organizational devices equipped with EDR/XDR solutions, disk encryption, automated patch management, and mobile device management (MDM) controls.
- Network Security: Zero Trust Architecture with network segmentation, next-generation firewalls, intrusion detection/prevention systems (IDS/IPS), and continuous network monitoring.

β Litigation Hold Override
When litigation is reasonably anticipated or active, all relevant data must be preserved regardless of the retention schedule. The Legal Department issues formal litigation hold notices to all relevant custodians, suspending automated deletion processes.
Data Disposal Procedures
When data reaches the end of its retention period and is not subject to a litigation hold or other preservation obligation, it must be securely disposed of using the following methods:
Flag Data for Disposal
Automated systems flag records that have reached their retention expiry. Data owners review and confirm the disposal authorization.
Obtain Disposal Authorization
Data owner and compliance officer approve the disposal. For Level 4 data, C-suite sign-off is required.
Secure Destruction
Electronic data: NIST 800-88 compliant wiping or cryptographic erasure. Physical media: Cross-shredding (6mm or less) or incineration by certified vendor.
Certificate of Destruction
Generate and archive a certificate of destruction documenting what data was destroyed, when, by whom, and by what method. Retain certificates for 3 years.
Disposal Methods by Media Type
| Media Type | Disposal Method | Standard |
|---|---|---|
| Hard drives & SSDs | Degaussing + physical destruction or crypto-erase | NIST SP 800-88 Rev. 1 |
| Paper documents | Cross-cut shredding (β€6mm particle size) | NAID AAA Certification |
| Optical media (CD/DVD) | Shredding or incineration | NIST SP 800-88 |
| Cloud data | Secure deletion + confirmation from provider | SOC 2 / ISO 27001 |
| Mobile devices | Factory reset + data wiping + physical destruction of storage | NIST SP 800-88 / DoD 5220.22-M |
| Backup tapes | Degaussing + physical destruction | NIST SP 800-88 |

Frequently Asked Questions
Data retention schedules should be reviewed at least annually, or whenever there are significant changes in applicable regulations, business operations, or organizational structure. After any data breach or regulatory audit, an immediate review is recommended to identify gaps and update retention periods accordingly.
A litigation hold (also called a legal hold) is a directive to preserve all potentially relevant data when litigation is reasonably anticipated or active. It overrides normal retention and disposal schedules. All automated deletion processes for affected data must be suspended, and custodians must be notified to prevent data spoliation. Litigation holds should be documented, tracked, and released only when the legal obligation has ended.
Under most data protection regulations including GDPR and CCPA, data should only be retained for as long as necessary to fulfill the purpose for which it was collected. Indefinite retention is only justifiable for specific categories such as corporate governance records or where explicitly required by law. Over-retention creates unnecessary risk exposure, storage costs, and compliance complications.
Penalties vary by jurisdiction and regulation. GDPR can impose fines up to β¬20 million or 4% of annual global turnover. CCPA allows for statutory damages of $100-$750 per consumer per incident. HIPAA violations can result in fines from $100 to $50,000 per violation tier, up to $1.5 million annually. SOX non-compliance can lead to criminal penalties including imprisonment. Beyond fines, organizations face reputational damage, loss of customer trust, and increased insurance premiums.
When a DSAR is received, the DPO or designated privacy contact acknowledges receipt within 5 business days and responds within 30 days (extendable by 60 days for complex requests). The request is verified for identity, relevant data is located across all systems, and a comprehensive response is prepared. Access logs, retention schedules, and disposal records must be accurate to efficiently respond to DSARs. This underscores the importance of maintaining up-to-date data inventories and automated lifecycle management.
Yes. This policy explicitly covers all data regardless of where or how it is stored, including public cloud, private cloud, hybrid environments, SaaS applications, and third-party data processors. Cloud providers must meet equivalent security standards, and data processing agreements must clearly define responsibilities for data protection, retention, and disposal. Cloud-specific controls such as shared responsibility models and cross-border data transfer mechanisms are addressed in the technical controls section.
