Data Lifecycle Management is a policy-driven framework governing data from inception to final disposition.

DLM aims to ensure data security, integrity, and availability throughout its lifespan.

DLM addresses data in various states, including at rest, in transit, and in use.

A primary goal of DLM is to eliminate the need for any data backups.

DLM applies exclusively to structured data stored in relational databases.

DLM focuses mainly on hardware life cycles rather than data policies and retention.

Automation and monitoring help enforce DLM policies across data activities.

DLM guarantees instant data recovery without any performance or cost trade-offs.

Classification and retention policies are core components of a DLM strategy.

The data lifecycle ends once data is created, with no further actions or reviews.

Confidentiality in DLM uses encryption at rest and in transit.

Data classification helps determine appropriate confidentiality measures.

Data integrity uses checksums and hash functions to detect corruption.

The CIA triad is Confidentiality, Integrity, and Availability.

Integrity relies solely on manual record-keeping without automation.

RAID arrays do not contribute to availability.

Encryption keys are unnecessary if the data is considered public.

Immutable audit trails can be deleted after compliance reviews.

An immutable audit trail is crucial for forensic analysis and compliance.

Data classification is optional for applying confidentiality measures.

In the Creation & Collection phase, data ingestion pipelines should use schema validation to reject malformed records.

Destruction includes data sanitization and, for physical media, certified destruction like shredding or degaussing.

The DLM framework has five phases: Creation & Collection, Storage, Usage, Archival, and Destruction.

RBAC is used in the Usage phase to control access based on role.

Storage uses data tiering to place hot data on high-performance storage and cold data on archival storage.

The Usage phase bypasses RBAC and allows unrestricted access to all datasets.

Destruction procedures may delete data without an audit log or verification.

In the Archival phase, data must always be kept on magnetic tape with no digital storage options.

Storage policies ignore data retention and never move data to a lower tier.

The Creation & Collection phase requires no data quality checks or validation.
