Compliance Evidence Map

Auditors, cyber-insurance underwriters and corporate clients ask for the same ten things, in different vocabularies, across almost every framework. This maps each of them to the technical control behind it, the artifact that actually proves it, and how a reviewer validates that the artifact is real rather than aspirational.

Conventional framework crosswalks map one control identifier to another. That helps an auditor and does very little for the person who has to produce something by Friday. The useful direction is the other one — from the question as it arrives to the record that answers it — which is what this page is.

What this is and is not.This is IT KORR's operational interpretation, written in plain language. It does not reproduce any framework's control text and does not copy or derive from any framework body's own published crosswalk. Use it to understand what you will be asked for and what produces it — and use the frameworks' primary sources, with your compliance function and counsel, to determine what specifically applies to you. IT KORR operates environments and produces evidence; it does not provide regulatory advice.

01

Access review

“Who had access to our systems and data, and when was that last checked?”

Who asks, and when
Auditors, cyber-insurance underwriters, and corporate clients running vendor or outside-counsel security reviews. It is the single most frequently asked question across all three.
What drives it
  • NIST Cybersecurity Framework — the Protect function treats identity management and access control as a core category
  • NIST SP 800-171 — the Access Control and Audit and Accountability families both require access to be limited and the limitation to be verifiable
  • HIPAA Security Rule — administrative safeguards require information-access management and periodic evaluation
  • SOC 2 — the common criteria concerned with logical access expect access to be authorised, reviewed and removed
  • PCI DSS — requirement areas covering identification, authentication and access restriction by business need-to-know
The technical control
Role-based access in Entra ID with group-based assignment rather than per-user grants; privileged roles held just-in-time rather than standing where licensing allows; joiner-mover-leaver process actually executed on HR events; access reviewed on a defined cadence by someone who can say yes or no.
The evidence artifact
A dated access review record naming what was reviewed, who reviewed it, what changed as a result, and what was accepted as-is. Plus a privileged-access inventory showing who holds administrative roles today.
How it is validated
A reviewer checks that the record has a date, a named approver, and a decision — not merely a list. Then they sample: pick two people who left in the period and confirm their access was removed, and when.
Where it usually fails
The control runs and leaves no evidence that it ran. Access genuinely is reviewed, informally, by someone who remembers doing it. From the outside that is indistinguishable from never having reviewed it at all.
02

Change control

“What changed in the environment, who approved it, and what was the risk?”

Who asks, and when
Auditors and customer qualification audits, particularly in regulated manufacturing and life sciences. Also the first question asked during a post-incident review.
What drives it
  • NIST Cybersecurity Framework — configuration and change management sit under the Protect and Identify functions
  • NIST SP 800-171 — the Configuration Management family requires baseline configurations and control over changes to them
  • SOC 2 — the common criteria covering change management expect changes to be authorised, tested and documented
  • PCI DSS — requirement areas covering change control and secure configuration
The technical control
A documented change process proportionate to blast radius, not an approval board for everything. Configuration baselines captured and version-controlled for network devices, servers and tenant policy. Changes recorded as they happen rather than reconstructed afterwards.
The evidence artifact
A change record per change: what, when, who authorised it, the assessed risk, and the rollback position. For infrastructure, a configuration backup from before and after.
How it is validated
A reviewer picks a change they can see evidence of in the environment — a firewall rule, a Conditional Access policy, a new server — and asks for its record. The test is whether the record exists, not whether the process is written down.
Where it usually fails
Network changes carry the widest blast radius of any routine IT change and are the most commonly made informally. The organisation has a change policy and no change records, which is the worst of both positions: the policy proves they knew it mattered.
03

Backup and recovery evidence

“Can you actually restore, and when did you last prove it?”

Who asks, and when
Cyber-insurance underwriters above all — tested recovery has become a routine condition of placement and renewal. Also auditors, and any client whose data you hold.
What drives it
  • NIST Cybersecurity Framework — the Recover function expects recovery planning and improvement, not merely backup
  • NIST SP 800-171 — the Media Protection and Contingency-related families address backup and the ability to restore
  • HIPAA Security Rule — administrative and technical safeguards require a data backup plan and a disaster recovery plan
  • SOC 2 — availability criteria expect recovery capability to be defined and tested
  • PCI DSS — requirement areas covering secure storage and the integrity of retained data
The technical control
Backup coverage reconciled against an actual asset inventory rather than assumed; retention set against the real obligation rather than a default; backups held outside the production administrative blast radius so a compromised administrator cannot delete them; and a restore actually performed, end to end, by whoever would do it in an incident.
The evidence artifact
A dated restore-test record naming what was restored, by whom, how long it took, and whether it met the stated recovery objective. Plus written RPO and RTO per workload — because without them a restore test has no pass condition.
How it is validated
A reviewer asks for the last restore test and compares the elapsed time against the stated RTO. A backup report showing success is not accepted as evidence of recovery, and increasingly is not accepted by underwriters either.
Where it usually fails
Backup success is mistaken for recovery readiness. Jobs report green for years; nobody discovers the gap until the restore that matters. Microsoft 365 is the most common blind spot — the platform provides retention, not backup.
04

Asset inventory

“What do you actually have, and is this list current?”

Who asks, and when
Auditors, insurers, and acquirers during technology diligence. It is the quietest question on the list and the one that most often derails the rest of the assessment.
What drives it
  • NIST Cybersecurity Framework — the Identify function treats asset management as foundational to everything after it
  • NIST SP 800-171 — several families depend on a defined system boundary, which requires knowing what is in it
  • HIPAA Security Rule — the risk analysis requirement cannot be satisfied without knowing where ePHI resides
  • PCI DSS — requirement areas covering inventory of system components in scope
The technical control
A maintained inventory of endpoints, servers, network equipment, cloud resources, SaaS subscriptions and the data each holds — reconciled against discovery rather than maintained by hand, with an owner per asset class and vendor end-of-support dates tracked against it.
The evidence artifact
The inventory itself, with a date and a stated reconciliation method. The method matters more than the list: an inventory nobody can explain how they produced is not evidence.
How it is validated
A reviewer picks something they can see — a server, a laptop, a SaaS tool mentioned in a meeting — and checks whether it appears. They also check whether anything in the list is lifecycle-expired and whether anyone noticed.
Where it usually fails
Nearly every other control depends on this one and it is the least glamorous to maintain. Organisations discover during an assessment that their inventory describes the environment of two years ago, at which point every downstream answer becomes unreliable.
05

Third-party and vendor oversight

“Who else can reach your systems or your data, and what did you check before letting them?”

Who asks, and when
Auditors and corporate clients, increasingly as a standing contractual obligation rather than a one-off question. Also the question that follows any supply-chain incident in the news.
What drives it
  • NIST Cybersecurity Framework — supply-chain risk management is an explicit category under the Identify function
  • NIST SP 800-171 — flows down to subcontractors handling the same regulated information
  • HIPAA — business associate relationships carry their own contractual and oversight requirements
  • SOC 2 — common criteria covering vendor and business-partner risk management
  • PCI DSS — requirement areas covering service providers with access to the cardholder data environment
The technical control
A vendor register recording access scope, data handled, review cadence and offboarding status — not a procurement list. Vendor access provisioned through the same identity system as staff, so it is visible in the same access review and revocable the same way.
The evidence artifact
The register, plus due-diligence records per vendor and evidence of access removal for vendors no longer engaged. The offboarding evidence is the part most often missing.
How it is validated
A reviewer asks for a vendor the organisation stopped using and checks whether their access was actually removed, and when. Unused vendor accounts with live access are a common and immediately damaging finding.
Where it usually fails
Vendors are assessed at onboarding and never reassessed, and access granted for a project outlives the project by years. The register, where one exists, records who was approved rather than who can currently get in.
06

Logging and audit-log retention

“Would you know, and could you reconstruct what happened afterwards?”

Who asks, and when
Auditors, insurers, and incident responders. In a breach investigation this becomes the only question that matters, and by then the answer is already fixed.
What drives it
  • NIST Cybersecurity Framework — the Detect function expects continuous monitoring and anomaly detection
  • NIST SP 800-171 — the Audit and Accountability family requires audit records sufficient to trace activity to individuals
  • HIPAA Security Rule — technical safeguards require audit controls over systems containing ePHI
  • SOC 2 — monitoring criteria expect activity to be logged and reviewed
  • PCI DSS — requirement areas covering logging of access and retention of audit history
The technical control
Audit logging enabled across identity, email, file and endpoint estates, with retention set deliberately. In Microsoft 365 the retention period available is partly a licensing decision, which is frequently discovered during an investigation rather than before one. Monitoring that distinguishes degraded from down, with defined escalation.
The evidence artifact
The configured retention period per log source, with a statement of the obligation it was set against, and evidence that someone looks at the output on a cadence.
How it is validated
A reviewer asks how far back the organisation could reconstruct administrative activity, and compares that to the obligation. The gap between "logging is on" and "logs are retained long enough to be useful" is where most organisations sit.
Where it usually fails
Logging is enabled at defaults and nobody checks what the default retention actually is until an investigation needs ninety days of history and finds thirty.
07

Incident response

“What is the plan, who executes it, and when did you last exercise it?”

Who asks, and when
Insurers at placement and renewal, auditors, and corporate clients whose contracts specify notification timelines.
What drives it
  • NIST Cybersecurity Framework — the Respond function covers response planning, communications and analysis
  • NIST SP 800-171 — the Incident Response family requires an operational capability and testing of it
  • HIPAA Security Rule — administrative safeguards require security incident procedures
  • SOC 2 — criteria covering incident identification, response and communication
  • PCI DSS — requirement areas covering an incident response plan and its testing
The technical control
A plan that matches the current environment, with named roles rather than job titles that no longer exist, defined notification paths including contractual and regulatory ones, and out-of-band communications that do not depend on the system most likely to be unavailable.
The evidence artifact
The plan, dated, plus a record of the last exercise and what it changed. An exercise that changed nothing is usually an exercise that was not real.
How it is validated
A reviewer checks whether the plan references systems and people that currently exist, and asks for the date of the last test. A plan describing infrastructure retired two years ago is worse than no plan, because it is trusted.
Where it usually fails
The plan is written once to satisfy a requirement and then diverges silently from the environment. Nobody reads it again until the incident, when its inaccuracies cost time at the point time is most expensive.
08

Data protection and handling

“Where does our data live, who can reach it, and how is it protected?”

Who asks, and when
Clients during vendor review, auditors, and anyone whose own regulatory obligation flows down to you as their supplier.
What drives it
  • NIST Cybersecurity Framework — data security sits under the Protect function and covers data at rest, in transit and in use
  • NIST SP 800-171 — the System and Communications Protection and Media Protection families address confidentiality of regulated information
  • HIPAA Security Rule — technical safeguards address transmission security and encryption as an addressable implementation specification
  • SOC 2 — confidentiality and privacy criteria where those categories are in scope
  • PCI DSS — requirement areas covering protection of stored account data and encryption of transmission
The technical control
A current picture of where regulated or client data actually resides, including the integrations around the primary system. Encryption in transit and at rest as a verified state rather than an assumption. Sensitivity labelling and data-loss prevention where the data warrants it, and external sharing policy that is reviewed rather than set once.
The evidence artifact
A data-flow description naming systems, third parties and data types, with the protection applied at each point. Plus the configured external-sharing and labelling state.
How it is validated
A reviewer asks where a specific data type goes and follows it. Most organisations can describe their primary system confidently and become vague at the integrations — which is exactly where the question lands.
Where it usually fails
External sharing expands during projects and never contracts. The boundary that exists on the architecture diagram stopped matching the tenant configuration some time ago, and nobody has looked.
09

Privileged access

“Who holds administrative rights, and are those rights standing?”

Who asks, and when
Insurers, auditors and incident responders. It is also the finding most consistently flagged when anyone looks properly.
What drives it
  • NIST Cybersecurity Framework — least privilege and separation of duties under the Protect function
  • NIST SP 800-171 — the Access Control family addresses privileged account use and the logging of it
  • HIPAA Security Rule — administrative safeguards covering authorisation and supervision of workforce access
  • SOC 2 — logical access criteria covering privileged access specifically
  • PCI DSS — requirement areas covering administrative access and multi-factor authentication for it
The technical control
An inventory of who holds which administrative roles; MFA enforced on every one without exception; just-in-time elevation rather than standing privilege where licensing supports it; break-glass accounts established, held by the organisation, and excluded from the policies that could lock everyone out.
The evidence artifact
The privileged-access inventory with a review date, plus evidence that break-glass accounts exist, are monitored, and are held by the organisation rather than by a provider.
How it is validated
A reviewer counts Global Administrators. The expected answer is a small number that the organisation can name. An answer of "we would have to check" is itself the finding.
Where it usually fails
Administrative access accumulates. Accounts created for a migration, a vendor, or a former employee retain standing privilege indefinitely, and the organisation genuinely does not know the count.
10

Documentation and knowledge continuity

“If the person who built this left tomorrow, could anyone else run it?”

Who asks, and when
Acquirers during diligence, auditors indirectly through every other question, and boards after a key-person departure makes the risk concrete.
What drives it
  • NIST Cybersecurity Framework — governance and asset management both presuppose a documented environment
  • NIST SP 800-171 — system security plan requirements presuppose that the system can be described accurately
  • HIPAA Security Rule — documentation requirements include retaining policies and records of required actions
  • SOC 2 — criteria covering defined responsibilities and documented processes
The technical control
Topology, IP plan, VLAN register, configuration baselines, recovery runbooks, vendor register and access records maintained as current records rather than as a one-off project. The practical test is whether a competent engineer who has never seen the environment could use them to find a fault at 2am.
The evidence artifact
The documentation set itself, with evidence of currency — ideally because updating it is part of the change process rather than a separate quarterly chore.
How it is validated
A reviewer compares the documentation against something observable in the environment. Documentation that was accurate when written and has not been maintained fails this immediately.
Where it usually fails
Documentation exists, was produced for an audit, and describes a past state. The organisation believes it is covered, which is more dangerous than knowing it is not.

The Pattern

Ten domains, not fifty — and that is the actual finding

The frameworks are largely asking the same operational questions in different vocabularies.

An organisation facing HIPAA, a SOC 2 report, a cyber-insurance renewal and three corporate client questionnaires can reasonably believe it is facing four separate programmes. In evidence terms it is mostly facing one. The same access review record answers a question from each; the same restore test satisfies all four; the same vendor register appears in every one.

The recurring failure is never an absent control. It is a control that operates and leaves no record. Access really is reviewed, by someone who remembers doing it. Changes really are considered. Backups really do run. None of that survives sampling, because from the outside a control with no record is indistinguishable from a control that does not exist.

Which makes the practical goal narrower than it first appears: not implementing fifty controls, but making the ten you already operate produce a dated record as a by-product of running. That is an operating-cadence problem rather than a technology problem, and it is the reason IT KORR publishes the full documentation standard it works to — you can read which artifacts get produced, and on what cadence, before committing to anything.

FAQ

Common Questions

What is a compliance evidence map?

It is a mapping from the questions auditors, insurers and clients actually ask to the artifacts that answer them. Conventional framework crosswalks map one control identifier to another, which helps an auditor and does very little for the person who has to produce something. This maps the other chain: what gets asked, which framework areas drive it, what the control looks like in a real Microsoft 365 or infrastructure environment, what artifact proves it, and how a reviewer validates that artifact is real rather than aspirational.

Is this an official mapping between NIST, HIPAA, SOC 2 and PCI DSS?

No, and it is important to be clear about that. This is IT KORR’s operational interpretation, written in plain language. It does not reproduce any framework’s control text and does not copy or derive from any framework body’s own published crosswalk. Use it to understand what you will be asked for and what produces it; use the frameworks’ own primary sources, and your compliance function or counsel, to determine what specifically applies to your organisation.

Which frameworks does this cover?

The requirement areas described here are drawn from the NIST Cybersecurity Framework and NIST SP 800-171 (both U.S. government publications in the public domain), the HIPAA Security Rule (federal regulation), and the requirement areas of SOC 2 and PCI DSS described in original words. The ten domains were chosen because they are what actually gets asked, not because they map neatly onto any one framework’s structure — in practice the same handful of artifacts satisfies most of what several frameworks want.

Why do the same ten things keep coming up across different frameworks?

Because the frameworks are largely asking the same operational questions in different vocabularies. Access control, change management, recovery, asset inventory, vendor oversight, logging, incident response, data protection, privileged access and documentation recur across almost every framework and almost every insurer questionnaire. That is genuinely good news: an organisation that operates these ten domains well can answer most of what it is asked without a framework-specific project for each one.

We have the controls but not the evidence. Is that a real problem?

Yes, and it is the most common finding on this entire page. A control that operates but leaves no record is, from the outside, indistinguishable from a control that does not operate. Access genuinely gets reviewed by someone who remembers doing it; changes genuinely get considered before they are made. Neither survives contact with an auditor. The fix is usually not new controls but making the existing ones produce a dated record as a by-product of running.

What is the fastest way to close an evidence gap before an audit?

Honestly, there is no fast way to produce historical evidence you did not record, and anyone offering one is describing something you should not want. What can be done quickly is to establish the record going forward, document the current state accurately, and be straightforward with the assessor about when the practice started. Assessors deal with this constantly; a clear statement of when a control was formalised reads far better than reconstructed records that do not survive sampling.

Does IT KORR provide compliance consulting?

No, and the boundary matters. IT KORR operates the technology environment and produces the operational evidence that compliance programs, auditors, insurers and clients ask for. Determining which obligations apply to your organisation, and how they should be interpreted, is work for your compliance function and your counsel. We would rather state that plainly than let an IT engagement be mistaken for regulatory advice.

How does this relate to the IT KORR operating standard?

Directly — the operating standard is where the artifacts in the right-hand side of this map come from. It publishes, in advance, what records IT KORR produces, what each one contains, and on what cadence. That is why the last column of this map can name an artifact rather than describing an aspiration, and it is the reason this page could be built at all.
