RES / RES-04
Ransomware-resilient backup implementation
Build backup arrangements whose data and administration better withstand compromise of the primary environment. The project combines access separation, protected copies, monitoring and restore testing.
WHEN IT HELPS
A focused response
to a defined need.
Backups managed through production accounts, copies deletable from the network, no recent restore tests or ransomware-recovery requirements.
SCOPE & OUTCOMES
What the engagement covers.
Scope
- Data and dependencies
- isolation
- separate identities
- immutability or offline copies as appropriate
- encryption and keys
- retention
- monitoring
- tests
- recovery procedures
Deliverables
- Backup architecture
- policies
- access matrix
- configurations
- recovery procedure
- restore results
- capacity and cost estimates based on actual volumes
Acceptance evidence
Copies are protected by the selected mechanism; access is separated; controlled restoration succeeds; backup errors are reported; retention and deletion limits are understood.
DELIVERY
How the work is structured.
Approach
Define objectives and ownership; prepare scenarios and resources; perform authorised response or exercise; document evidence; improve and revise.
Prerequisites & responsibilities
Customer: decision-makers, operations, business owners, legal/insurer where required, permissions and recovery resources. Provider: contracted expertise with evidence preservation.
Scope factors
Criticality, scope, investigation depth, data volume, dependencies, scenarios and mobilisation terms. Preparation, response, rebuilding and licensing are separate.
Questions to clarify
Can a compromised administrator delete every copy? Will keys remain available? Has an entire application been restored, not just a few files?
IMPORTANT BOUNDARIES
Immutable does not mean invulnerable or automatically compliant. Replication and synchronisation do not always replace backups; compromise, keys and recovery still need assessment.
Recovery and investigation have limits; no total recovery or absolute resolution-time promise. Exercise results remain specific to the tested scenario.
IN PRACTICE
Illustrative situations.
These examples describe possible engagements and target outcomes. They are not customer references or achieved results.
Scenario 01
A company stores copies on a share accessible to all administrators. Project: isolate storage and redesign identities. Target outcome: deletion is less accessible from a compromised production account and recovery is verified.
Scenario 02
A company enables immutability without testing lifecycle behaviour. Project: validate retention, costs and isolated restoration. Target outcome: usable copies; deletion constraints and costs are accepted before rollout.
Technology and reference context
Examples: backup solutions, locked storage and isolated copies; mechanisms and limitations verified in provider documentation.
The final technology set is agreed during scoping, based on interoperability, licensing, access rights and operating requirements.
