How to use this record

Use this record for every review of privileged activity: who used administrator rights, when, on which systems, and whether each use matches an approved ticket and the rules of the Privileged Access Standard. One record per review. A review is done by someone other than the administrators whose activity it covers. It is the evidence that privileged activity was reviewed at the cadence the standard sets, by someone with no administrator rights in the tier, and that anything unexplained was followed up (PA-09).

A review that finds nothing is a valid result, if the logs were complete. A review that could not see part of the period has not found nothing: the gap is recorded as a gap, and followed up.

Review schedule

Each scope, how often, and how soon after the period the review is due:

Scope

How often

Due

What is looked at

SV-0 Tier 0

Weekly

[[2]] working days after the period

Every privileged event: elevations, group and role changes, sign-ins by Tier 0 accounts, vault openings and changes to logging

SV-1 Tier 1

Monthly

[[5]] working days after the period

Every event without a matching ticket, and a sample of [[20]] elevations

SV-2 Tier 2

Quarterly

[[10]] working days after the period

A sample of [[20]] uses of local administrator passwords and service desk resets

SV-S Supplier sessions

Monthly

[[5]] working days after the period

Every supplier session, against the approved windows, with the remote support tool's recording where one exists

SV-B Break-glass use

Every use

[[1]] working day after the period

Every action the account took, against the declared reason

Who reviews

The session reviewer [[e.g. Information Security Manager]]: reviews privileged sessions and runs the control review. Holds no administrator rights in the tier reviewed. Every break-glass use is reviewed by the Head of Information Security, from the log the account cannot change (PA-12).

The review keeps these duties apart, from the P02 conflict matrix:

Conflict

The two duties

How the review keeps them apart

SOD-IT-03

Administer a system with privileged access; and review a system's audit logs

Privileged activity logs go to a store administrators cannot change, and sessions are reviewed by someone with no administrator rights in that tier (PA-08, PA-09).

SOD-SO-04

Investigate security incidents; and administer a system with privileged access

When an incident involves an administrator's own systems, their activity is preserved and reviewed by someone else before they investigate (PA-09).

Sources

Every privileged sign-in, elevation, change to a privileged group or role, and vault opening must be logged to a store administrators cannot change or delete, and kept for at least [[12]] months. Forward the directory's security events (for Windows: 4624 sign-in, 4672 special privileges assigned, 4728, 4732 and 4756 group membership added), the cloud tenant's audit and sign-in logs and servers' administrator command logs to the central log store the monitoring provider keeps.

A saved search per tier over the forwarded logs, run by the reviewer at the cadence set, compared with the ticket list. Supplier sessions are recorded by the remote support tool where it can.

Reading the seven questions

Read each question literally. A Yes to something that should not happen, or a No to a match that should exist, is an anomaly for Part C. A question about whether an event happened, such as a reset or a break-glass sign-in, is answered No when none happened; that is not a failed control.

Question

A finding looks like

Where to look

SQ-1 Does every elevation match an approved ticket, within its time and scope? (PA-07)

An elevation with no ticket, a window longer than approved, rights or systems beyond the ticket, or an approver who is the account's holder.

Group or role membership changes in the directory and cloud tenant logs, against the ticket list.

SQ-2 Was any privileged right granted or used outside an elevation? (PA-06)

A privileged right used by an account with no active elevation, or a right added outside the just-in-time route.

Privileged sign-ins and special privileges assigned, against the elevation windows.

SQ-3 Did any administrator account sign in outside its tier, or to email or the web? (PA-13)

An administrator account signing in to a system of another tier, or to email or a website that is not an administration portal.

Sign-in logs by account and target system, against the tier of each system.

SQ-4 Was any break-glass account used, and was the use declared? (PA-12)

A break-glass sign-in that nobody declared, or one whose alert did not fire.

Sign-ins by the break-glass accounts, and the alert log.

SQ-5 Did any service account sign in interactively? (PA-11)

A service account signing in at the console, by Remote Desktop or through a remote support tool.

Interactive sign-in events by service accounts; the remote support tool's session list.

SQ-6 Was logging stopped, cleared or changed? (PA-08)

Logging stopped, cleared or its settings changed, or a gap in the logs nobody can explain.

Audit policy changes, log-cleared events, and the log store's own record of gaps.

SQ-7 Was any privileged password or second factor reset, and did it follow PA-17? (PA-17)

A privileged password or second factor reset without the face-to-face or video check, the call back and a second administrator.

Reset events, against the reset tickets.

Sampling

Tier 0 and break-glass reviews look at every event. The Tier 1 and Tier 2 reviews take a sample of [[20]], and the Tier 1 review also looks at every event without a matching ticket, whatever the sample. Choose the sample before looking at the events: every n-th elevation in the ticket list, or a random draw recorded in Part A. A sample picked after reading the logs tests nothing.

Where the sample finds an anomaly, widen it: review every event of the same account, system or kind in the period, and record the wider scope in Part A.

Worked example: the first weekly Tier 0 review

EXAMPLE, not part of the record. The organisation is the one used throughout the pack: a wholesale distributor with about 900 staff, three warehouses and an online ordering service that takes 60% of its orders. It moved Tier 0 to security keys and just-in-time elevation on 21 Sep 2026, and started the weekly Tier 0 review with that week. Replace it with your own, or delete it from the adopted record.

Part B, answered:

Question

Rule

Answer

What it means

SQ-1 Does every elevation match an approved ticket, within its time and scope?

PA-07

Yes

All 7 elevations matched an approved ticket, within their window and the Tier 0 maximum, each approved by someone other than the account's holder. A match does not excuse what happened inside the window (SQ-3).

SQ-2 Was any privileged right granted or used outside an elevation?

PA-06

No

No privileged right was used outside an elevation in the period.

SQ-3 Did any administrator account sign in outside its tier, or to email or the web?

PA-13

Yes

adm-pshah signed in to FS-02, a Tier 1 file server, at 11:10 on 24 Sep while its Backup Operators elevation (E-04) was active. Anomaly AN-01; finding PF-03.

SQ-4 Was any break-glass account used, and was the use declared?

PA-12

No

No break-glass sign-in in the period. The last use, BGU-2026-01 on 5 Sep 2026, had its own review.

SQ-5 Did any service account sign in interactively?

PA-11

No

No interactive sign-in by the Tier 0 service account (svc-backup).

SQ-6 Was logging stopped, cleared or changed?

PA-08

No

No change to logging, and no gap in the period.

SQ-7 Was any privileged password or second factor reset, and did it follow PA-17?

PA-17

No

No privileged password or second-factor reset in the period.

The Head of Information Security, with the record, on 28 Sep 2026

Conclusion

Tier 0 elevations are approved and time-limited as the standard sets. One account spans Tier 0 and Tier 1 and was used across them; until it is split, the weekly review checks it by name.

Completed on

28 Sep 2026

On time?

Yes: due 29 Sep 2026

Done on 28 Sep 2026, one working day before it was due: September's session reviews were 1 of 1 on time (PAM-07, on target). The weekly Tier 0 review began with the week of 21 Sep 2026; the first monthly Tier 1 and supplier reviews fall due in October. (EXAMPLE)

Worked example: a break-glass use reviewed late

EXAMPLE. BGU-2026-01: bg-cloud-01, 22:40 to 23:05 on 5 Sep 2026, used by Beth Owen, the managed IT provider's on-call engineer (P06 SUP-001). A sign-in policy change made at 22:10 required a compliant device that no administration device met, and locked every administrator out of the cloud tenant.

Reviewed

25 Sep 2026, by Ruth Okafor

14 working days late

Outcome

Every action matched the reason: the policy was rolled back at 22:52 and nothing else was changed.

Nothing outside the declared reason

The break-glass use on 5 Sep 2026 was declared and the credential changed on time, but nobody reviewed the session: the Head of IT thought the provider would, and the provider thought the Head of IT would. The use came before the standard was approved on 18 Sep 2026, so no record and no named reviewer existed yet. The control review on 24 Sep 2026 found it, and both actions were done the next day: review the session (Head of Information Security, 25 Sep 2026) and name the Head of Information Security as the reviewer of every use in the break-glass checklist (Head of IT, 25 Sep 2026). PAM-06 for the quarter is 0 of 1, outside tolerance (target: all, with no tolerance below it). (EXAMPLE)

When the review finds a tier breach

Every system must have a tier, and administrator accounts must follow the separation rules. An administrator account used outside its tier, or for email or browsing, is treated as a possible exposure of its credential. The Privileged Access Request, Elevation & Revocation Procedure sets the steps; in summary:

Step

What to do

When

1

Stop the use and end the account's sessions

At once

2

Change the account's password and revoke its sessions and tokens

At once for Tier 0; within [[1]] working day for Tier 1 and 2

3

Check the system or mailbox it touched for signs of compromise; if there are any, it is an incident under the incident management pack (P09)

[[1]] working day

4

Review what the account did since the breach

[[1]] working day

5

Fix the cause: the right-tier account for the person, and a policy that blocks the sign-in next time

[[1]] month

6

Record it in the session review record, and as a finding if the policy failed

In the next review

Record the breach in Part C, and the finding in Part D if a policy should have blocked the sign-in. In the EXAMPLE, AN-01 was contained the day it was found and the touched server checked the next day; the fix that stops it recurring, split the account into a Tier 0 and a Tier 1 account, and deny Tier 0 groups sign-in on Tier 1 servers, is due 28 Oct 2026.

Adapting this template

Guidance — delete before approval

Small organisation: a monthly review of every privileged event can be enough while there are few administrators; keep the weekly Tier 0 review and the review of every break-glass use. If nobody inside is independent of the administrators, ask your security monitoring provider or an outside adviser to do the review and sign the record.

Regulated entity (NIS2, DORA): NIS2 Article 21(2)(i) expects access control to be applied and checked. A DORA financial entity limits access to approved functions (Article 9(4)(c)) and keeps users identifiable for their actions (Delegated Regulation (EU) 2024/1774, Article 21(c)); this record is the evidence that privileged actions were traced to a person and an approval.

IT run by a service provider: where the provider administers your systems, its sessions are in scope and are reviewed by your reviewer, never by the provider itself. Ask for the remote support tool's recordings and the provider's ticket references.

Delete this section before approval.

Definitions

Term

Meaning in this record

Anomaly

An event the review cannot match to an approved ticket and the rules, or a Yes to a question about something that should not happen.

Break-glass account

An emergency account used only when the normal administration route is unavailable, such as when every administrator is locked out. Sealed, watched, tested and reset after every use (PA-12).

Elevation

One activation of just-in-time rights: who, which rights, which system, why, who approved, when it started and when it ended.

Interactive logon

Signing in as a person would: at the console, through Remote Desktop, or through a remote support tool. A service account must not be able to.

Privileged account

Any account that holds privileged access, standing or when elevated: a named administrator account, a supplier's administrator account, an application administrator role, a service account, a shared or built-in administrator account, or a break-glass account.

Session review

A check, by someone other than the administrator, that privileged activity in a period matches approved tickets and the rules, with anything unexplained followed up (PA-09).

Tier

A group of systems that give the same level of control over the organisation. An administrator account belongs to one tier (A08).

Tier breach

An administrator account used outside its tier, or for email or browsing. Treated as a possible exposure of that account's credential (PA-13).

Working day

Monday to Friday, excluding [[public holidays where you are]].
