Quick answer
The Recover function of the NIST Cybersecurity Framework 2.0 (RC) covers the activities an organization performs to restore systems, data, and operations after a cybersecurity incident. It contains two categories: Incident Recovery Plan Execution (RC.RP) and Incident Recovery Communication (RC.CO). The goal is to return to normal operations as quickly as possible while keeping the impact of the incident as small as possible.
This is part 9 of the SEVN-X Cybersecurity Frameworks Series. The inevitable (they say) has happened. You have had a significant event, you know what happened, and you have contained the attack. Now what? That is where RECOVER comes in—and the single biggest factor in how well it goes is how much you prepared before the incident. Recover well and you prepared. Skip the preparation and recovery gets hard, or in some cases impossible.
What is the Recover function in NIST CSF 2.0?
Recover (RC) is the sixth and final core function of the NIST Cybersecurity Framework 2.0, alongside Govern, Identify, Protect, Detect, and Respond. NIST released CSF 2.0 in February 2024, and the full framework spans 6 functions, 22 categories, and 106 subcategories. Recover is the function you lean on after an incident has been detected and contained—its job is to restore the assets and services that the incident disrupted, and to confirm you are truly back to a normal, trustworthy operating state.
What are the two categories of the Recover function?
The Recover function is organized into two categories. One is about doing the restoration work; the other is about telling the right people how it is going.
RC.RP
Incident Recovery Plan Execution
Carrying out the restoration activities that bring affected systems and services back to operational availability.
RC.CO
Incident Recovery Communication
Coordinating recovery activities and updates with internal and external stakeholders.
RC.RP
Incident Recovery Plan Execution
RC.RP is where restoration activities are performed to ensure the operational availability of systems and services affected by the incident. It has six subcategories. Here is the official outcome for each, with a plain-English read on what it means in practice.
RC.RP-01
The recovery portion of the incident response plan is executed once initiated from the incident response process.
You flip from “responding” to “recovering” on a defined trigger, not by gut feel.
RC.RP-02
Recovery actions are selected, scoped, prioritized, and performed.
Decide what to restore, in what order, based on business criticality.
RC.RP-03
The integrity of backups and other restoration assets is verified before using them for restoration.
Confirm your backups are clean and uncompromised before you trust them.
RC.RP-04
Critical mission functions and cybersecurity risk management are considered to establish post-incident operational norms.
Define what “normal” looks like after the incident, not just before it.
RC.RP-05
The integrity of restored assets is verified, systems and services are restored, and normal operating status is confirmed.
Prove the restored environment is sound before you call it done.
RC.RP-06
The end of incident recovery is declared based on criteria, and incident-related documentation is completed.
A formal, criteria-based “we are recovered” call—plus the paperwork.
A note from the field: there is often a great deal of overlap between the recovery portion of an incident response plan and a disaster recovery plan. At some organizations they are literally the same plan. RC.RP-03 calls for testing your backups, which is about as common-sense a control as it gets—it is hard to imagine being comfortable without a successful recovery test on the record.
We always recommend a documented and tested DR / BCP, but the shape of your recovery depends on your environment. Organizations that are already largely in the cloud, with solid cloud backup, can make recovery faster and more straightforward. We have seen some smaller businesses recover without a formal documented plan. Complex organizations with many systems and applications do not get that luxury—they need to understand every business process and define a recovery priority that puts the most critical functions first.
RC.CO
Incident Recovery Communication
RC.CO ensures restoration activities are coordinated with internal and external parties. It requires a communications plan and defined stakeholders, ideally named in advance as part of your recovery plan. In CSF 2.0 this category has two subcategories.
RC.CO-03
Recovery activities and progress in restoring operational capabilities are communicated to designated internal and external stakeholders.
Keep the people who need to know informed as restoration progresses.
RC.CO-04
Public updates on incident recovery are shared using approved methods and messaging.
Any public statements go out through pre-approved channels and language.
The practical takeaway: have a policy on who is authorized to communicate externally, and decide it before you need it. External communication may also carry legal weight. The SEC cybersecurity disclosure rules require public companies to disclose material cybersecurity incidents in a timely manner, which makes your recovery communications and your regulatory obligations part of the same conversation.
How do you execute the Recover function effectively?
In practice, an effective recovery follows a repeatable sequence:
01. Trigger recovery on a defined signal. Initiate the recovery plan from the incident response process, not on a hunch (RC.RP-01).
02. Prioritize by business criticality. Scope and sequence restoration so your most critical mission functions come back first (RC.RP-02, RC.RP-04).
03. Verify backups before you trust them. Confirm the integrity of backups and restoration assets so you do not reinfect yourself (RC.RP-03).
04. Restore, then prove it. Bring systems back, verify the integrity of restored assets, and confirm normal operating status (RC.RP-05).
05. Communicate on approved channels. Update internal and external stakeholders, and route any public statements through pre-approved messaging (RC.CO-03, RC.CO-04).
06. Declare the end formally. Close the incident against defined criteria and complete your documentation (RC.RP-06).
Recover vs. Respond: what is the difference?
Respond (RS) is about managing an incident while it is active—analyzing it, containing it, and mitigating the damage. Recover (RC) picks up after containment and focuses on restoration: bringing systems and services back to a normal, verified operating state and communicating that progress. Put simply, Respond stops the bleeding; Recover gets you back on your feet. The two overlap, and both should be exercised together in your incident response planning.
Frequently asked questions
NIST CSF Recover FAQs
Why is backup testing part of the Recover function?
Because a backup you have never tested is a guess, not a safety net. RC.RP-03 requires verifying the integrity of backups and restoration assets before you use them, so you do not restore corrupted data or reintroduce the attacker's foothold during recovery.
Does the Recover function require public communication about a breach?
It requires that public updates, when you make them, go out through approved methods and messaging (RC.CO-04). Whether you are obligated to disclose depends on your regulatory environment—for public companies, the SEC's rules require timely disclosure of material incidents.
When is a cybersecurity incident considered recovered?
When the integrity of restored assets is verified, systems and services are back to normal operating status, and the end of recovery is formally declared against defined criteria with documentation completed (RC.RP-05 and RC.RP-06). “It seems fine now” is not the standard.
Is a disaster recovery plan the same as the Recover function?
They overlap heavily, and at some organizations the recovery portion of the incident response plan and the disaster recovery plan are the same document. The Recover function is broader in that it also covers stakeholder communication, not just technical restoration.
Key takeaways
- Recover (RC) is the sixth NIST CSF 2.0 function and handles restoration after an incident.
- It has two categories: Incident Recovery Plan Execution (RC.RP) and Incident Recovery Communication (RC.CO).
- Preparation is everything—untested backups and undocumented plans are where recovery fails.
- Prioritize restoration by business criticality, verify integrity before and after, then declare recovery formally.
