Managing Data Retention: Developing a Secure Information Lifecycle Strategy

With rapidly expanding data volumes, effectively managing retention and disposal is critical for security, compliance and operational efficiency. However, without data lifecycle strategies aligning storage to governance policies, organizations struggle balancing accessibility needs with security obligations.

This guide provides pragmatic steps for security leaders seeking to implement secure information lifecycle management programs.

Classify Information by Sensitivity

The first priority is developing a data classification methodology cataloging organizational information assets based on sensitivity and business impact.

Effective classification involves:

Exactingly categorized data streamlines compliance while enabling precision access controls.

Define Retention Schedules

Once classified, retention periods can be defined per data type covering both primary storage duration as well as archived requirements.

Implementing retention schedules necessitates:

Automated expiration adherence reduces legal oversights while limiting data leakage windows.

Secure Data Disposal

Upon retirement, proper data destruction is imperative, especially for sensitive assets, to prevent posthumous exposure.

Methods like cryptographic erasure and physical destruction of storage media should be standardized through:

Absolute and provable data removal caps lifecycles enabling asset repurposing without breach liability.

By aligning classification, expiration and disposal, chief information security officers can oversee the full data journey. For additional guidance explore resources such as the SANS SEC304 Data Security course.
