PS-1 Policy and procedures: requirements and evidence

What the PS-1 personnel security policy must cover before an assessor will accept it

PS-1 asks for two documents: a personnel security policy and the procedures that put it into practice. The policy can be set at the organization, mission or business process, or system level, and it must be disseminated to defined roles, owned by a designated official, and reviewed and updated at a frequency the organization defines and after defined events. If an audit or authorization is coming and that document either does not exist or has not been looked at in a long time, this is the control an assessor will test first, because the other personnel security controls (PS-2 through PS-9) depend on the rules it sets. Before drafting anything, confirm which level your policy will sit at and whether an existing enterprise policy already covers it, so you do not write a second document that contradicts the first.

The risk PS-1 addresses is inconsistency. When there is no written standard, one manager screens a contractor thoroughly and another does not, a leaver keeps access for weeks because nobody owned the offboarding step, and a transfer leaves old permissions in place. A policy that names its purpose, scope, roles, responsibilities, management commitment and coordination among HR, security, legal and system owners gives each of those decisions one reference point. The policy should also state who answers questions about it and how non-compliance is handled, since assessors commonly ask how the policy connects to sanctions under PS-8 and to the position descriptions under PS-9.

Three problems cause most rejections. The first is a policy written once and never reviewed, with a revision date that predates the current workforce model. The second is procedures that describe a process the HR and IT teams do not follow, which assessors catch by comparing a few real termination or transfer tickets against the written steps. The third is unclear ownership, where nobody can say who approves changes or who was told about the latest version. Ask your HR, IT and security leads to walk through the last several hires, transfers and departures, then compare what they did with what the documents say. Confirm your review frequency and event triggers with your own governance rules, because the standard leaves those values to the organization.

Which systems, teams and baselines bring PS-1 into scope

PS-1 looks like a single policy document, but the scope decisions around it determine how many policies, procedures and owners an assessor will read. Settle the baseline, the level, the personnel groups, the inherited systems and the parent policies before drafting anything.

Baseline allocation

SP 800-53B allocates PS-1 to the low, moderate and high baselines, so any system categorized at those impact levels carries the control. PS-1 is not part of the privacy baseline, so a system scoped only to the privacy baseline does not bring PS-1 in on that basis alone. Confirm the system's categorization and the baseline its authorization package cites before you size the policy work. If the system carries a tailored baseline, check whether PS-1 was kept, adjusted or removed in the tailoring record.

Level at which the policy is set

The PS-1 policy may be set at the organization, mission or business process, or system level. A single organization-level policy with system-specific procedures is the most common arrangement, but the choice must be stated and must match how the organization actually assigns personnel security responsibilities. Record the chosen level in the policy itself so an assessor does not have to infer it from the document's header.

Personnel groups the policy reaches

Decide whether the policy covers only employees or also contractors, service bureau staff and other external personnel. Contractors who access systems are usually handled through PS-7, so the PS-1 policy should state that external personnel are covered by the external personnel requirements and name the contract clauses that carry them. Without this boundary, assessors may find that the policy does not reach the people who hold privileged access.

Systems that inherit a common policy

When several systems share one organization-level policy, each system's security plan can inherit PS-1 as a common control rather than document it separately. Confirm which systems inherit the policy, who owns the inherited control, and whether each system's plan references the same policy version. An inheritance claim that points to a policy the system owner never reviewed is a common finding, so list the inheriting systems in the policy's scope statement.

Parent policies the PS-1 policy must align with

PS-1 should align with higher-level policies, including the risk management strategy that PM-9 requires. The PS-1 policy also relates to SI-12 on information management and to PS-8 on sanctions, so check that terms, roles and review cycles match across those documents. Ask the policy owner for the parent documents list and confirm each one is current before the PS-1 review date is set.

How scope changes the document count

A single organization-level policy with one procedure set produces a small document package, while separate policies for each mission area or system multiply the reviews, approvals and evidence that an assessor must read. Scope decisions therefore set the workload for both the organization and the assessor. Write the scope decision down early and ask the assessor to confirm that the chosen structure meets the control before the document set is finalized.

How an assessor tests PS-1 against SP 800-53A

This table groups the 17 PS-1 determination statements in SP 800-53A into six test areas and shows the method, evidence and common gaps for each. The 17 statements are assessed with examine and interview methods only, so every row depends on documents the assessor can read or on people the assessor can question. Use it to check whether your policy and procedures can be tested in these areas before the assessor arrives.

Test element	Method	Evidence requested	Common findings
Policy content	Examine the personnel security policy; interview personnel with security responsibilities	Current signed policy covering purpose, scope, roles, responsibilities, management commitment, coordination and compliance	Scope vague, management commitment missing, roles named by title only
Procedures	Examine the personnel security procedures	Step-by-step procedures showing how personnel security controls are carried out and who performs each step	Procedures restate the policy without describing steps or owners
Dissemination	Examine the policy and procedures; interview defined roles	Distribution records, acknowledgments, publication locations and access records for defined roles	No proof that defined roles received or can reach the policy
Designated official	Examine the policy and appointment records; interview the official	Named official, appointment record, documented authority and an alternate	Owner is a departed employee or an unnamed team
Review and update cycle	Examine policy version history and audit findings	Review dates, change log, approvals and updates made after defined triggering events	Review overdue, or no update after reorganization, incident or audit finding
Risk strategy and audit inputs	Examine risk management strategy documentation and audit findings	Risk strategy addressing personnel risk; findings linked to policy or procedure changes	Audit findings closed without updating the policy; risk strategy silent on personnel

Which documents pass PS-1 and how to keep them current between audits

An assessor testing PS-1 reads the policy and procedures first, then checks whether they match what the organization does in the other personnel security controls. The cards below list the artifacts that usually carry that weight, and each one points to the PS-2 through PS-9 records it must agree with.

Approved personnel security policy

The policy document itself, with a stated purpose, scope, roles, management commitment, and coordination and compliance statements. Check that the scope names the systems and personnel it covers and that management commitment is signed by an official with authority over the program. Confirm that the screening, termination and access agreement rules it states match the PS-3, PS-4 and PS-6 records in use today.

Personnel security procedures

The step-by-step procedures that put the policy into practice, such as how a new hire moves through risk designation, screening and access approval. Assessors compare these with real tickets and checklists. Confirm that each procedure names a responsible role and points to the PS-2 designation records and PS-5 transfer forms it depends on.

Dissemination record

A record showing which defined roles received each version of the policy and procedures, when they received it, and how they confirmed receipt. Keep it in the same system as the policy so the two cannot drift apart. Check that the recipient list matches the roles named in the policy and the position descriptions under PS-9.

Designated official appointment

The written appointment of the official who manages the personnel security policy and procedures. The appointment should state the official's authority, the decisions they own, and how they are replaced. Confirm that the named official still holds the role and that the appointment is referenced in the policy's roles section.

Review log with triggering events

A dated log of each review and update, showing the reviewer, the outcome and the event that caused any off-cycle change, such as a reorganization, a sanctions case under PS-8 or a finding from an earlier assessment. The review frequency and triggering events come from the organization's own policy, so confirm the log meets both. Gaps in the log are a common assessment finding.

Version history of changes

A record of what changed in each version, when, and by whom, with the ability to compare any two versions and restore an earlier one. This lets an assessor see whether the policy was updated after events such as a new screening requirement or a change to access agreements under PS-6. Keep the history in a system that cannot be silently edited, and confirm that approved versions cannot be overwritten.

How to write, approve and maintain the PS-1 policy and procedures

This sequence produces a personnel security policy and a matching set of procedures that name owners, reflect how screening, termination and transfer actually run, and carry a dissemination record and review schedule an assessor can test.

Confirm the level and scope of the policy
Decide whether the personnel security policy applies at the organization, mission or business process, or system level, and list the systems, business units, contractors and locations it covers. Confirm which SP 800-53B baseline applies to each system, since PS-1 sits in the low, moderate and high baselines and not in the privacy baseline. The output is a short scope statement that the policy will cite, plus a list of the systems it governs. Ask the risk or compliance lead to sign off the scope before drafting begins, so later control mappings do not have to be reopened.
Name the designated official and procedure owners
Assign one designated official accountable for the personnel security policy, and name an owner for each procedure, typically HR for hiring and termination, the security function for screening and access reviews, and line managers for transfers. Record each role in a responsibility matrix that the policy references. The output is that matrix with named roles, not individuals alone, so the policy survives staff changes. Confirm that management has committed resources to the policy, because the policy must state management commitment and assessors examine it.
Draft the policy elements
Write the policy to address purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance. Keep each element specific to your environment: who is responsible for screening, how coordination with HR and facilities works, and how compliance is checked. Link the policy to the related PS controls (PS-2 through PS-9) so readers can trace each requirement to its procedure. The output is a draft policy document with version number and effective date fields left ready for approval.
Write procedures that match actual workflows
Document the procedures that implement the policy by walking through how screening, termination and transfer happen today, step by step, with the system or form used at each point. Interview the people who perform each task and compare their description with the written procedure. Where they differ, change the procedure or the practice before approval. An assessor who interviews the same staff will test whether the document and behavior agree. The output is a procedure set with one document per workflow, each naming its owner and its evidence record.
Approve, disseminate and record acknowledgment
Obtain formal approval of the policy and procedures from the designated official and the accountable executive, then distribute them to the defined roles through the channel your staff actually use. Keep a dissemination log that shows who received each version, when, and through which channel, and where possible capture acknowledgment. Store approved versions under version control so the approved text can be retrieved for any past date. The output is the approved policy, the procedure set and the dissemination log, which together show the control was implemented, not only written.
Set the review frequency and event triggers
Define how often the policy and procedures are reviewed and updated, and list the events that force an earlier review, such as a significant change in HR systems, a reorganization, a security incident involving personnel, or a change to a related control. Assign a reviewer for each review and record the date, findings and resulting changes. Confirm the frequency and triggers against your organization's own governing requirements, because NIST leaves the specific interval to the organization. The output is a review calendar and a review record that an assessor can compare with the version history.

How XWiki and BookStack can hold PS-1 documents with version history

PS-1 expects a personnel security policy and procedures that are disseminated, owned and reviewed on a defined cycle. Two self-hosted wikis, XWiki and BookStack, can hold those documents with change history and role-based editing, but they only store the record. Approval, export and retention must be set up and confirmed in your own environment.

XWiki version control for policy pages

XWiki keeps every change to a page under version control, recording what changed, when and by whom. Users can compare any two versions and roll back to an earlier one. For PS-1, this gives an assessor a dated trail showing when the personnel security policy and procedures were revised and what the previous wording said. Check that the wiki is the only place the current policy is published, so a reviewer does not find a stale copy elsewhere. Confirm that the licence (LGPL-2.1-or-later) and your hosting model fit your obligations.

BookStack role-based editing

In BookStack, user abilities come from the roles assigned to each user, and permissions can be overridden per role at the shelf, book, chapter or page level. For PS-1, this lets you restrict who may edit the personnel security policy while allowing HR and security staff to read it. Map each role to a named owner in the policy so the designated official can show who may change the document. Test the permissions with a sample account before relying on them, because overrides at a lower level can change the effective access.

Approval workflow outside the wiki

Neither wiki provides a formal sign-off that a named official approved a revision, so approval has to be recorded separately. Many organizations keep a dated approval record, such as a signed memo or ticket, and link it from the page. Decide which step is the approval, who may give it, and whether a page is published only after that record exists. Confirm in your own environment how approvals are captured, because an edit history alone does not show that management endorsed the content.

Export formats and retention

PS-1 documents must remain available to assessors for the period your records schedule requires, and to support interviews and sampling. Confirm the export formats each wiki supports, whether version history survives export, and how long backups and old page revisions are kept. Test a restore of an older policy version from backup, not only from the live wiki. Record the retention decision in the policy itself so the reader can see how long earlier versions remain available.

Wiki as record, not proof

A wiki shows what was written and when, but it does not prove the content was implemented, understood or enforced. An assessor will also look for evidence that roles received the policy, that reviews occurred on schedule and that personnel followed the procedures. Keep the wiki as the record store and pair it with acknowledgments, review minutes and implementation evidence. Treat the wiki as one input to the assessment, not the assessment result, and confirm with your assessor which records they will accept.

What writing and maintaining PS-1 costs in money and effort

This table compares the cost components of building and keeping up the PS-1 policy and procedures, who is paid for each, whether it is one-time or recurring, and what pushes it up or down. No supplied figure exists for these costs, and NIST does not estimate compliance costs, so use the table to shape a written scope and quote request rather than to budget.

Cost component	One-time or recurring	What drives it up	How to keep it down
Drafting the personnel security policy	One-time, then revised	Number of system boundaries and business processes the policy must cover, and whether it is set at organization, mission or system level	Write one organization-level policy and reference it from system-level documents instead of duplicating text
Legal and HR review of the policy	One-time, then at each revision	Number of reviewers, employment-law questions in each jurisdiction, and unions or works councils that must be consulted	Agree the review list and turnaround in the written scope before drafting starts
Writing procedures across the PS family	One-time, then revised per procedure	Number of PS controls covered (PS-2 through PS-9) and how many distinct HR and IT workflows each procedure describes	Reuse the PS-1 structure for each procedure and keep procedures tied to the systems they govern
Designating and training the responsible official	One-time designation, recurring training	Size of the organization, number of teams involved and turnover in the role	Name a role rather than a person where possible and record the training in the normal learning system
Dissemination and acknowledgment tracking	Recurring	Number of defined roles, contractors who need the policy, and how often staff change	Publish to a single controlled location and tie acknowledgment to onboarding and role changes
Annual or event-driven review and update	Recurring	Review frequency set by the organization, number of triggering events, and changes to laws, systems or organizational structure	Set a realistic review frequency in the policy and track trigger events in a single change log
Evidence upkeep and version history	Recurring	Number of documents, approval steps and how many versions must be retained for the assessment period	Use version-controlled wiki pages so every change, author and date is recorded automatically
Assessor sampling of records	Recurring at each assessment	Sample size the assessor selects, how many roles and procedures are in scope and how quickly records can be retrieved	Keep dated approvals, acknowledgments and review records in one place so samples can be produced quickly

Who owns the PS-1 policy, who helps and who signs off

Your organization owns the personnel security policy and the procedures that implement it. Leadership must formally approve the policy, name a designated official who manages it, and make sure the defined roles actually follow it. Human resources and legal teams are normally the people who check that the policy fits employment practice, labor agreements and local law, because PS-1 work touches hiring, offboarding and sanctions. The organization also decides the scope of the policy, whether it applies at the organization, mission or business process, or system level.

Policy approval: A named executive or governance body signs the policy and records the approval date and version.
Designated official: One accountable person maintains the policy and procedures and tracks review dates.
HR and legal review: These teams confirm that screening, termination and sanction language is consistent with employment rules.
Dissemination: The organization sends the policy and procedures to defined roles and keeps acknowledgment records.
Review schedule: The organization sets the review frequency and the events that trigger an update, then follows them.

Before engaging anyone, confirm which individuals hold each of these roles and whether they have the authority and time to sign off.

Common questions about PS-1 cost, effort and ownership

Does one enterprise personnel security policy satisfy PS-1, or does each system need its own?

PS-1 allows the personnel security policy to be set at the organization, mission or business process, or system level, so one enterprise policy can satisfy the control if it covers the systems in scope. Many organizations use an enterprise policy and add system-level procedures where roles, screening levels or termination steps differ. The assessor will check that the policy reaches every system in the authorization boundary and that any narrower documents do not contradict it. Confirm the level you choose with your assessor before drafting, because the answer depends on how your authorization boundaries and business units are defined.

How long does drafting a PS-1 policy and procedures take?

No fixed duration applies, because drafting time depends on scope rather than on the control itself. The main drivers are how many systems and business units the policy covers, how many existing HR and security documents must be reconciled with it, how many approval layers exist, and whether the procedures must be written separately for each system. Ask any partner for a written scope that lists the documents to produce, the reviewers, and the approval path, then build the schedule from that list. A partner can prepare drafts and evidence, but the timeline still depends on your internal review and sign-off cycle.

Can our own team write the PS-1 policy without outside help?

Yes, an organization can write its own PS-1 policy and procedures, and many do. The organization owns the control, so internal staff with HR, security and governance knowledge can draft the policy against the control's required elements: purpose, scope, roles, responsibilities, management commitment, coordination and compliance. The work is less about wording and more about making sure the procedures match how HR actually runs screening, transfers and terminations. If internal staff lack time or experience with assessment expectations, an implementation partner can help prepare the documents, but it does not replace internal ownership.

What does the PS-1 work need from HR, legal and system owners?

HR owns the operational steps that the procedures describe, so HR must confirm how position designations, screening, transfers and terminations really happen today. Legal must review the policy against employment law, labor agreements and any contract terms that limit what screening or monitoring is allowed. System owners must confirm which personnel roles they rely on and how access is requested and removed in their systems. Each group should sign off on the parts that describe its work. Expect the most time to go to reconciling what the procedures say with what teams actually do, because gaps found there usually drive revisions.

How often must the PS-1 policy and procedures be reviewed and updated?

PS-1 requires the organization to define both a review and update frequency for the policy and for the procedures, and to define the events that trigger an earlier update. The standard does not set those values for you, so you must choose them and document them. Base the frequency on your own governance rules, any contract or regulatory obligations, and how often your personnel processes change. Confirm the chosen frequency and triggering events with your assessor and internal policy owner before the first review cycle, because an assessor will test whether you followed the schedule you wrote down.

Can a partner sign or approve our PS-1 policy on our behalf?

No. An implementation partner can draft the policy, prepare procedures and assemble evidence, but the organization must approve and own it, typically through a named official who is accountable for the personnel security program. Only an independent auditor, assessor or certification body issues assessment reports or certificates, and no DeployOpen work produces either. Approval records, signatures and version history should show your own officials and reviewers. Keep those records in your document system so the assessor can see who approved each version and when.

How DeployOpen prepares the PS-1 policy set and its evidence

DeployOpen works on PS-1 as a document and evidence set that runs inside your own environment, not as a template you adopt unchanged. We help you agree which policy and procedure documents cover your organization, configure the self-hosted tools that hold them, and prepare the records an independent assessor will ask for. The organization owns the policy content and its approval, and an independent assessor or certification body issues any report.

How we scope

Agree in writing which personnel security policy levels apply: organization, mission or business process, or system.
Confirm the named designated official who owns the PS policy and the procedures that implement it.
Define the review frequency and the events that trigger an update, using values your leadership approves.

How we build

Draft a PS policy skeleton covering purpose, scope, roles, management commitment, coordination and compliance for your review.
Configure a self-hosted wiki with version history so every policy and procedure change records what changed, when and by whom.
Set role-based permissions so only the designated owners can approve and publish PS documents.

How we hand over

Deliver a mapping from each PS-1 assessment determination statement to the document or record that answers it.
Provide a dissemination record template showing which defined roles received each policy and procedure version.
Hand over the document repository, admin notes and a review calendar so your team can run updates without us.

How we support

Engagements are fixed-scope, with scope, deliverables and timelines agreed in writing before work starts.
Ongoing support, upgrades and updates to the PS document set are available as a retainer.
Ask your independent assessor to confirm which evidence formats they accept before we finalize the record set.
