Appendix B — Ticket-to-Machine Reference

The reference tables and worked examples behind Chapter 10: the coordination loop and the five-clause request chain, which operation classes go to a machine, which stay with a human, which are handled by protocol and which become declared exceptions, the approval each class needs and the evidence each produces, the severity tempo, four illustrative worked examples, and the failure modes a reference implementation review found.

A ticket is evidence only when it authorized something that then ran, and a re-read proved the result.

NoteIn this appendix

The tables that Chapter 10 relies on: the coordination loop and the five clauses every governed request passes through, the lanes that each operation class takes, the approval each lane needs and the evidence each lane leaves, and the severity tempo. Then four worked examples, the program’s exception for certificates, the one-front-door rule for detection tools, and the failure modes a security review of a reference implementation found. The control-by-control mapping is in Appendix A.

ImportantProgram design, with illustrative examples

The lanes, ceilings, severities and response windows in this appendix are the Federal Modernization Program’s design, not federal requirements. Where a federal document says something relevant, it is cited. The worked examples are illustrative patterns, not records of a real engagement, and every identifier in them is invented. Product capabilities change quickly; confirm current behavior with each vendor before a plan, procurement or acquisition decision rests on this appendix.

Watch or present it: a narrated, self-running edition of this appendix (about 10 minutes, captions) walks through the loop, the lanes, the tempo and the worked examples; the deck, script and video are on the Presentations page. For the same loop on named products, see the draft example guide Ticket-to-Machine on ServiceNow and SailPoint, a companion to this vendor-neutral reference.

The coordination loop

Native consoles can detect drift and change state, and their dashboards show current posture inside their own boundary. What a console can’t do on its own is answer the four questions an assessor asks about a finding: who owns it, by when, under whose approval, and with what evidence of closure. The program puts a coordination layer in front of the native tools to answer them, and keeps every change on the native surface:

1. Test. A rule evaluates actual state against the authoritative record (Chapter 05).
2. Detect drift. A difference becomes a typed finding with a severity (Chapter 06).
3. Raise a typed task against the reconciled configuration item, with an owner and a clock.
4. Actuate on the native surface, under a service identity, through the platform’s own interface.
5. Close with evidence: re-read the post-change state and write one record of the whole chain.

The coordination layer never writes the configuration, applies the patch or edits the firewall rule itself. Its job is to make every drift an owned, clocked, approved and evidenced piece of work. The default shape of change management fails that job even with a ticket in front of it: a ticket tells a person to open a console, the person does the work and replies “done,” and the ticket records a claim. In the program’s model the ticket authorizes a machine; the person’s role ends at approval.

This lines up with where federal policy is pointing. OMB asked FedRAMP to oversee a cloud provider’s change process itself rather than each individual change.¹ FedRAMP’s 2026 rules let providers make routine recurring changes, the daily work of fixing flaws, handling incidents and doing maintenance, without formal notification, while keeping auditable records of how each change was classified.² And FedRAMP’s change management indicator prefers redeploying version-controlled resources to modifying them in place “wherever reasonable.”³ Those rules bind providers, not agencies; the program applies the same logic to an agency’s own estate.

The five-clause request chain

Every governed change, every move, add, change, deletion and reset, travels the five clauses of Book 00, Chapter 04. In the coordination layer they run in order, and if any clause fails the chain stops and the task is not treated as closed. A refusal is written to the record like a success.

Clause	What the coordination layer checks	Refuses when	Evidence it leaves
1. Originates with the source of truth	The task traces to a lineage record: a drift finding, an HR event or an approved request	No origin record resolves	The origin record’s identifier
2. Carries an authoritative authorization	The approver resolves from the authority model; separation of duties holds, fail-closed	The requester or the plan’s author is the approver; the target isn’t reconciled to the authoritative record	Approver, approval time, the authority rule that resolved
3. Executes under least privilege, elevated just in time	The executing identity activates a time-boxed, scoped role, then the native write runs through the platform’s interface	No activation is issued (no activation, no actuation); the grant requested would be standing; the write is rejected	Activation identifier and expiry; run log tied to the task; artifact version
4. Closes with provenance	The post-change state is re-read from the platform; a success response is not closure	The re-read doesn’t show the intended state	Verification payload, timestamp, identity of the checking mechanism
5. Emits verified, secured evidence automatically	One closure record flows into the continuous-monitoring stream with no human assembly	The record can’t be written or signed	The closure record in the evidence chain (Chapter 07)

The chain mirrors the Book 01 actuation ladder: clause 2 is the human authorization that L3 gated actuation requires for each instance, or the advance acceptance of the class at L4, and clause 4 is the re-test that makes the result something an authorizing official can rely on. Privileged elevation follows Book 04’s request-with-approval model.

Operation classes and their lanes

Each operation class takes one of five lanes. (The five change classes of Chapter 04, move, add, change, deletion and reset, are a different cut.) The lane decides who approves, what runs and what evidence results.

Lane	Who approves	What executes	Evidence produced	Ladder ceiling
Machine, autonomous	The class, accepted in advance and in writing by the authorizing official, with its scope limits, exclusions and after-the-fact review rate; the governance board reviews each such class quarterly	The execution layer through a native interface, inside the response window	Finding, rule and baseline version, before and after state, re-read, run log	L4, enumerated low-blast-radius classes only
Machine, gated	A named approver who isn’t the requester or the plan’s author, per instance, ring or approved batch	The execution layer after a dry run, under a service identity	The above, plus the approval, the dry run and the activation	L3, the default ceiling
Human decision	The role that owns the decision	Whatever the decision authorizes, usually the gated lane	The decision record, then the gated-lane evidence	L2 until decided
Protocol-enforced	The policy encoded in the protocol and in DNS	The issuing protocol, with no ticket per event	Issuance logs, inventory, policy records	Not a ticket lane
Declared exception	The system owner writes it up with a named compensating control and an end date; the CISO approves a dated exception, and the authorizing official accepts an open-ended one	A person, through a time-boxed, proxied and recorded privileged session	The approval first, then the session recording	Temporary; tracked to closure

The classes below are the program’s starting assignment. An agency tunes them in its own authoritative record; a class moves only by a reviewed change to that record.

Operation class	Example	Lane	Approval needed	Evidence beyond the lane’s default
Configuration drift with a deterministic fix, low or medium severity	A setting on a dormant or historical configuration item reverted by hand away from the secure baseline	Machine, gated; autonomous only where the class is enumerated at L4	Per instance at L3; the class in advance at L4	The baseline version the fix restored
Configuration drift with a deterministic fix, high severity	A storage account opened to public network access	Machine, gated, inside a 1-hour window; a person decides the fix if it isn’t deterministic	Named approver per instance, unless the class is enumerated at L4	Exposure window, from first detection to re-read
Critical drift, or authorization, provenance or identity drift on a claim in active use	A change with no provenance event; a policy that contradicts a principal’s recorded assurance level	Halt and alert, then human decision	By the escalation path in the finding’s contract: the steward for a finding about the record, the system owner and platform team for a finding on a platform, the CISO for one that bears on a control requirement or on evidence	Investigation notes linked to the finding
Vulnerability remediation and patching	A missing security update on a server fleet	Machine, gated by maintenance window	Change approval for the window or batch	Scan before and after; time against the response window
Access request inside policy	A user requests a role an approver can grant	Machine, gated through the five clauses	The approver named for that role	The just-in-time activation and its expiry
Over-privilege or idle entitlement finding	An identity holding an entitlement unused for 90 days	Human decision by the entitlement owner, then gated removal	Entitlement owner	The owner’s decision and the re-read of the binding
High-blast-radius change	A tenant-wide role, a Conditional Access enforcement change, bulk device state, network policy touching thousands of endpoints	Machine, gated, permanently	Named approver, after a dry run	Dry-run output and rollback plan
Change to the authoritative record itself	A new baseline, a rule threshold, a change to which source is authoritative	Human decision	Reviewed pull request; steward and sponsor for architecture or authoritative-origin rules	The merged change and its review
Routine certificate issuance and renewal within policy	A web server’s certificate renewed automatically	Protocol-enforced	None per event	Issuance and inventory records
Certificate anomaly	A new issuing CA, a non-standard lifetime, a trust anchor change, an unknown-issuer certificate found in inventory, a blocked issuance attempt against a CAA record	Human decision, then gated	PKI owner	The anomaly finding and its disposition
No machine actuator exists yet	An appliance with no supported interface	Declared exception	System owner writes it up with compensating control and end date; CISO approves a dated exception, authorizing official an open-ended one	Session recording; the exception’s POA&M item
Emergency change	Containment during an incident	Act first under incident procedures, then record	Incident commander; retrospective review	Retroactive task and assessment

Two rules hold across the table. A machine never changes the authoritative record to make drift disappear: authority to change the record belongs to its review process, not to an adapter’s fix path. And no class routes a gap through a person at a console without saying so: where no machine can reach the surface, the exception is declared, approved first and recorded.

The emergency row follows the shape FedRAMP gives providers: significant changes may be made during an emergency without advance notification, provided procedures are followed, parties are notified and the materials and assessment are completed afterward.⁴ Decision rights for every approver named above are in Book 00, Chapter 07; the authorizing official alone accepts residual risk.

Drift classes and their default lanes

The program’s drift classes, as Book 02 names them, map to lanes by default. Chapter 06 carries the full model.

Drift class	What it means	Default lane
Schema	A value’s encoding or structure doesn’t match the current schema	Machine-executed when the transform is deterministic, gated at L3 unless the authorizing official has accepted the class at L4; a format failure is critical and halts (Chapter 06)
Semantic	A value is well formed but means the wrong thing, such as a deprecated naming pattern	Machine, gated; often escalates
Provenance	A state change appears with no provenance event	Halt and alert when the claim is in active use (P1); otherwise a P3 human decision (Chapter 06)
Authorization	A policy contradicts what the record says a principal may do	Halt and alert when the claim is in active use (P1); otherwise a P3 human decision (Chapter 06)
Identity	A principal exists with no counterpart in the record, or the reverse	Halt and alert when the claim is in active use (P1); otherwise a P3 human decision (Chapter 06)

Severity and tempo

The tempo is how quickly each severity must be handled. It bounds the response, not the occurrence: drift is the signal, and a program with no findings is more likely blind than clean.

Severity	May a machine fix it?	Response window	Who approves
P1, critical	No: the run halts and alerts	Immediate	A named role decides before anything changes
P2, high	Yes, if the fix is deterministic and the class qualifies	1 hour	An approver per instance, unless the class is enumerated at L4
P3, medium	Yes, if the class qualifies	24 hours	An approver per instance, or the class approved in advance
P4, low	Yes, if the class qualifies	72 hours	The class approved in advance, reviewed after the fact, or an approver per instance

The source of this tempo said P3 and P4 findings auto-remediate. In the program’s model that holds only for classes enumerated at L4; everywhere else the machine executes after a person approves, which is still a ticket to a machine. Chapter 10 gives the six tests a class must pass to qualify.

These are the program’s internal windows for drift against its own record. They don’t replace external timelines: CISA’s BOD 26-04 sets remediation timelines for vulnerabilities by exposure, KEV status, automatability and technical impact, and an agency’s vulnerability findings follow those.⁵ Where both apply, the external clock governs whenever it is shorter or different in kind (Chapter 10).

The tempo also names measures that belong to program leadership, not only to operations. Chapter 10 defines them:

Measure	Question	What a bad value means
Detection coverage	What share of the estate emits drift findings?	Drift outside coverage is invisible to the tempo
Window adherence	What share of findings close inside their window, and how many are open past it?	The program is generating drift in its own operations
Escalation rate	What share of findings reach a human?	Severity is rising, or the classifier needs tuning
Machine-closure share	What share of closures did a machine execute under an approval?	Actuators aren’t being added
Declared-exception count	How many open tasks have no machine actuator?	Manual work is becoming permanent

A tempo doesn’t need round-the-clock staffing: low and medium findings close through approved plans and L4 classes, and critical findings halt and hold until a person responds. It does need the escalation roles to exist. A program without a steward has to designate one; the tooling can’t create authority.

The evidence record

Every lane writes the same record shape, so an assessor reads one format whatever the platform.

Field	Machine lanes	Declared exception	Protocol-enforced
Origin	Finding or request identifier	Finding identifier	Issuance policy identifier
Owner and clock	Task owner, response window, due time	System owner, end date	PKI owner
Approval	Approver and time, or the L4 class acceptance and rule version	Approver and time, before the session	Policy version
Executing identity	Service identity, activation identifier	The person, through the recorded session	The protocol client’s identity
What ran	Version-controlled artifact and its hash	The session recording	The issuance transaction
Result	Re-read post-state and time	Re-read post-state and time	Certificate in inventory
Closure	One record linking all of the above	Same, plus the POA&M item	Inventory entry

This is what the assessor checks: the change traces to a prior approval, the artifact that ran is version-controlled and access-restricted, the execution is logged and attributable to the task, and the result is re-testable. The controls those properties evidence, CM-3, CM-5(1), CM-4(2) and AU-10 among them, are mapped in Appendix A. Chapter 07 covers how the record is protected and signed.

NIST’s guidance is balanced on the point that matters here: organization-wide monitoring “cannot be efficiently achieved through manual processes alone or through automated processes alone,” and where manual processes are used they must be repeatable and verifiable.⁶ The declared-exception lane exists to meet that test for the work machines can’t yet do.

Worked examples

All four examples are illustrative. Names, identifiers and times are invented.

Example 1: a configuration setting drifts

1. The nightly rule run compares a cloud tenant’s sharing setting to the baseline in the authoritative record and finds it set to allow anonymous links. The rule is deterministic, the setting is live, so the finding is P2, and in this example the authorizing official has accepted this class, restoring one named sharing setting on one tenant to its baseline, for L4.
2. The governance platform raises task FMP-DRIFT-0412 against the tenant’s configuration item, owner the collaboration platform team, due in 1 hour.
3. Because the class is enumerated at L4, no per-instance approval is needed. The execution layer activates its service identity, calls the tenant’s configuration interface to restore the baseline value, and records the artifact version that ran.
4. It re-reads the setting, finds the baseline value, and closes the task with one record: finding, baseline version, before and after values, run log and re-read time. Without the L4 acceptance, step 3 would wait for a named approver; nothing else would change.

The evidence an assessor would read: a CM-6 deviation detected and corrected, a CM-3 record of the change, and a CA-7 monitoring result, all from one task. If the setting drifts again the next week, the second finding links to the first, and a pattern of repeats becomes a question for the record’s steward, not another silent fix.

Example 2: an access request through gated actuation

1. A user requests an administrative role for a project. The request carries origin record REQ-2291. Clause 1 passes.
2. The approver named for the role in the authoritative record approves. Clause 2 checks that the approver isn’t the requester; it passes.
3. The execution layer activates a just-in-time role for its own identity, expiring in one hour, and assigns the user’s role through the directory’s interface as eligible for the project’s duration, not standing. Clause 3 passes.
4. It re-reads the user’s role assignments and finds the eligible assignment with its end date. Clause 4 passes.
5. One closure record, with the request, approval, activation, run log and re-read, flows into the evidence chain. Clause 5 passes.

Had the requester tried to approve their own request, clause 2 would have refused and the refusal would be the record. Book 04, Chapter 09 covers the review cycle that later recertifies the grant.

Example 3: an unknown-issuer certificate

1. The certificate inventory finds a certificate on an internal web server issued by a CA that isn’t in the approved list. Routine issuance never raises a ticket; an anomaly does.
2. The finding becomes task FMP-PKI-0087, owner the PKI owner, severity P2. No automatic fix applies, because replacing a certificate without knowing who depends on it can break a service.
3. The PKI owner decides to replace the certificate through the approved issuer and to add the rogue CA to the trust-store deny list. The decision is recorded.
4. The replacement runs in the gated lane: the protocol client on the server requests a new certificate from the approved issuer, and the platform re-reads the endpoint to confirm the new chain.

Example 4: no actuator yet

1. A drift finding names a legacy network appliance whose only management surface is an interactive console. No machine actuator exists.
2. The system owner writes up a declared exception and the CISO approves it: a named engineer, a two-hour window, access through the privileged access proxy with session recording, and a compensating control of daily configuration export and comparison. The exception carries an end date and a POA&M item for building an actuator or retiring the appliance.
3. The engineer makes the change inside the recorded session. The platform re-reads the appliance’s exported configuration and closes the task with the recording attached.

The exception is visible, approved before the work, and temporary. A silent console session for the same change would have produced none of that.

The certificate exception

Certificates are a large share of operational work, so it’s tempting to route them through the same front door. The program doesn’t, for routine lifecycle events, and the reason is volume. A configuration-drift finding is occasional and each one deserves a decision. A certificate estate with short validity periods generates renewals continuously, and publicly trusted TLS certificates are moving from a maximum of 398 days to 47 days in steps from March 2026 to March 2029.⁷ Routing every renewal through an approval ticket wouldn’t add rigor; it would train approvers to approve without reading.

So routine issuance is protocol-enforced and engine-driven (see Certificates in this book and the CLM platform). ACME automates issuance once a client proves control of a name, with no person in the loop.⁸ CAA records let a domain holder name the CAs allowed to issue for it, which puts part of the issuance policy in DNS where machines check it.⁹ Short-lived certificates make expiry, not revocation, the normal end of a certificate’s life. The anomalies, listed in the lanes table, still come through the front door, because they are rare, consequential and need a human. Book 07, Chapter 08 covers the certificate lifecycle and the tooling.

One front door for detection tools

Many tools detect: native cloud posture engines, vulnerability scanners, entitlement-management tools for cloud identity, certificate inventories. The program’s rule is that each is a detection engine feeding the one coordination layer, not a second coordination layer of its own. An entitlement tool that finds over-privileged cloud roles raises tasks in the same queue, under the same five clauses, as a posture engine that finds an open storage account. Access requests and recertifications can come from an identity governance front end; they land in the same record, correlated to the same request identifiers, with closure written back.

Two cautions keep this honest. First, check each detection tool’s actual platform coverage before counting on it; in the program’s own research, coverage of on-premises virtualization platforms was the gap that recurred across tool categories, and it should be treated as open until a vendor’s current documentation shows otherwise. Second, a reviewer will raise alternative architectures: a single multi-cloud posture engine in place of several native ones, or a compliance platform that generates the authorization package directly from machine-readable evidence. Neither changes the one-front-door rule, and both deserve a build-or-buy look before custom investment.

Failure modes found in a reference implementation review

The program built a reference implementation of the five-clause chain on an IT service management platform, covering an identity-lifecycle domain with both a cloud directory leg and an on-premises directory leg. An adversarial security review of the on-premises leg found defects that were then fixed. They are worth listing because each is a way the pattern fails while looking correct.

Failure mode	What went wrong	The fix, as a design rule
Origin not enforced	The chain accepted request identifiers without resolving them, so a caller with no lineage record could invoke it	Clause 1 resolves the origin or refuses; a negative test proves the refusal
Command injection	Parameter names were rendered unescaped into a script for the on-premises directory	Never build commands by string; escape or allow-list every name and value
Target substitution	A merge of caller input over defaults let input override the intended target	Fix the target from the authorized record; caller input can’t override it
Cleartext secret in a queue	A password crossed a work queue in plain text	Secrets never travel in task payloads; use a vault reference
No post-state re-read	One leg treated a successful dispatch as closure	Clause 4 re-reads on every leg; a success code is not evidence
Test mode skipped the risky path	Every test ran in a mode that short-circuited before the vulnerable code, so the tests never exercised it	Test mode refuses on production, and negative tests run the real path with hostile input

The same review supports two kinds of automated check. Negative tests prove the chain refuses what it must: self-approval, standing privilege, an unreconciled target, a missing origin and hostile parameter names. Build-time gates fail a build when a catalog item claims autonomous write without a recorded decision behind it, or when a control map names an actuator method that doesn’t exist. Neither proves the code does everything this appendix describes; they prove the specific refusals and mappings they test. The reference implementation is a starting point to build and test from, not evidence that any agency’s instance runs it.

Certificates in this book and the CLM platform

Book 07 gives each class of certificate one issuer and one renewal engine, and makes CyberArk Certificate Manager, Self-Hosted the system of record for every certificate that Intune and the PIV system don’t manage (Chapter 04, Chapter 05). The certificates this book’s systems depend on map to it as follows; Book 07, Appendix C describes the platform itself.

Certificate	Book 07 class	Issued by	Renewed by	What the CLM platform does
Routine server and public TLS renewals	Internal server TLS; public-facing TLS	Retained AD CS; public CA	CyberArk Certificate Manager	Drivers renew and install; ACME where the endpoint supports it
Device certificates	Device and user auth (Intune)	Cloud PKI, or AD CS through the Intune connector	Intune	Nothing
Domain controller certificates	Domain controller and LDAPS	Retained AD CS	AD CS autoenrollment	Watches
Unknown-issuer and out-of-policy certificates (the anomaly lane)	Internal server TLS	Any	CyberArk Certificate Manager	Network discovery finds them; placement and owners bring them under policy
Evidence signing certificate	Not a Book 07 class	Agency CA	Platform-managed, or not X.509	At most watches

This book’s certificates and the engine that renews each.

“Protocol-enforced” means engine-driven: Intune profiles, AD CS autoenrollment and the CLM platform’s drivers renew most certificates, and ACME automates issuance only where the endpoint supports it (Book 07, Chapter 08).¹⁰¹¹
