9 topics · 3 quiz questions

You cannot secure what you do not know you have. Asset management tracks every device, application and dataset from purchase to destruction.

Acquisition and assignment

Acquisition/procurement process
Buying through approved channels and vendors, with security requirements checked before purchase.
Ownership
Every asset has a named owner accountable for it.
Classification
Assets labelled by sensitivity and criticality to set protection levels.

Monitoring/asset tracking

Inventory
An accurate list of assets: what, where, who owns it, software version.
Enumeration
Actively discovering assets on the network (scans, agents) to find unknown or rogue devices.

Disposal/decommissioning

Sanitization
Removing data so it cannot be recovered: overwriting, cryptographic erase, degaussing (magnetic media).
Destruction
Physically destroying media: shredding, pulverising, incinerating. Used when media will not be reused.
Certification
Documented proof (certificate of destruction) that sanitisation or destruction was done, often from a third party.
Data retention
Keeping data only as long as required by law or business need, then disposing of it securely.
