It should also produce evidence that an authorized reviewer actually made a decision, because an audit isn't finished until someone's signed off. An export of account names isn't an audit. It's a starting population.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide gives IT leads a working checklist, a copyable audit register, a reviewer decision matrix and a closure procedure for Active Directory, Microsoft Entra, AWS and Google Cloud. You can use it for a quarterly control review or a targeted cleanup after a team or application changes.

It's meant to be marked up. Each item needs an owner, a source of evidence and a disposition. Marking an item complete without evidence just moves the uncertainty to the next audit.<\/p>\n\n\n\n<div class=\"ok-check\"><strong class=\"ok-check__h\">Service account audit: field-ready checklist<\/strong><ul><li>Define in-scope systems, identity types, reviewers and the review period.<\/li><li>Export accounts and workload identities from each directory, cloud and application.<\/li><li>Reconcile exports against the central inventory and investigate missing or duplicate records.<\/li><li>Record the stable object ID, environment, workload, business purpose and dependency owner.<\/li><li>Assign a named business approver and a technical custodian, with a backup contact.<\/li><li>Confirm that every active account is still authorized for its documented workload.<\/li><li>Inspect direct, inherited and delegated permissions against the task actually performed.<\/li><li>Identify privileged roles, wildcard grants, impersonation rights and shared credentials.<\/li><li>Record credential type, secret storage, expiration, rotation responsibility and exposure signals.<\/li><li>Review available authentication activity and changes; distinguish no activity from no telemetry.<\/li><li>Document breakage risk and a rollback path before disabling a suspected orphan.<\/li><li>Obtain approve, restrict, investigate or retire decisions from the accountable reviewer.<\/li><li>Track remediation tickets through implementation and verify the target system's final state.<\/li><li>Retain the population, attestations, exception approvals and post-change evidence together.<\/li><\/ul><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">An audit can be narrow if a system is under investigation, but its scope must be explicit. If you review only the Microsoft tenant, don't imply that the resulting evidence covers on-premises scheduled tasks or SaaS API users. The control owner should sign off on the population definition before sampling begins.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"copyable-service-account-audit-register-template\">Copyable service account audit register template<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The register below is designed for a spreadsheet, CMDB export or ticketing system. Copy the header row into your preferred tool. Don't put the credential itself in the spreadsheet: store a vault reference or key identifier, never a secret value.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Account or object ID<\/th><th>Source system<\/th><th>Workload<\/th><th>Business approver<\/th><th>Technical custodian<\/th><th>Effective access<\/th><th>Credential reference<\/th><th>Last observed activity<\/th><th>Review decision<\/th><th>Evidence link<\/th><\/tr><\/thead><tbody><tr><td>svc-orders-sync (example)<\/td><td>Active Directory<\/td><td>Sends approved orders to ERP<\/td><td>Operations lead<\/td><td>Integration team<\/td><td>Database read, ERP write<\/td><td>Vault record ORDERS-SYNC<\/td><td>Confirm from logs<\/td><td>Pending owner approval<\/td><td>Export and change ticket<\/td><\/tr><tr><td>app-billing-reports (example)<\/td><td>Microsoft Entra<\/td><td>Produces billing reports<\/td><td>Finance lead<\/td><td>Cloud platform team<\/td><td>Read-only reporting grant<\/td><td>Certificate ID only<\/td><td>Confirm from sign-in logs<\/td><td>Review privileges<\/td><td>Grant export and ticket<\/td><\/tr><tr><td>ci-build-role (example)<\/td><td>AWS IAM<\/td><td>Runs deployment workflow<\/td><td>Engineering lead<\/td><td>DevOps team<\/td><td>Scoped deployment policy<\/td><td>Role, no stored key<\/td><td>Confirm from logs<\/td><td>Retain with review<\/td><td>Role policy and approval<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The three rows above are <strong>illustrative records<\/strong>, not evidence of real systems. The final register should use immutable identifiers alongside display names because names can be reused or changed. Include an extraction timestamp and the person or automation that generated each source export. A reviewer should be able to reproduce the population later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"required-versus-useful-fields\">Required versus useful fields<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CIS Controls Safeguard 5.5 explicitly calls for a service account inventory with a <strong>department owner, review date and purpose<\/strong>, and for reviews of active-account authorization at least quarterly. That's a minimum inventory requirement, not a complete risk assessment, and it's easy to mistake one for the other. See the <a href=\"https:\/\/cas.docs.cisecurity.org\/en\/latest\/source\/Controls5\/\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">CIS Controls assessment specification<\/a> for the safeguard and its assessment inputs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you still need to build the inventory itself, start with our <a href=\"https:\/\/theitlead.com\/blog\/service-account-inventory-template\/\">service account inventory template<\/a>. Then add a stable identifier, named approver, technical custodian, workload, environment, effective entitlements, credential reference, last observed use, exception reason and evidence link. Those extra fields make decisions actionable, and they're cheap to collect. A team name may satisfy the department field but can't, by itself, explain why an integration still needs broad access.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CSV header to paste:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>object_id,identity_type,source_system,environment,workload,purpose,department_owner,business_approver,technical_custodian,backup_contact,effective_permissions,credential_type,vault_reference,last_observed_use,telemetry_coverage,review_date,decision,risk_reason,remediation_ticket,evidence_location,verified_final_state<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Don't paste passwords, private keys, refresh tokens or client secrets into this file. A safe evidence record points to protected systems without duplicating sensitive credentials.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-run-the-audit-from-discovery-to-closure\">How to run the audit from discovery to closure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A service account audit works best as a sequence of decisions rather than a one-time export. Separate discovery, authorization and remediation. The person who knows a workload is business-critical isn't always the person who understands its effective permissions, and that's why you split the questions.<\/p>\n\n\n\n<ol class=\"ok-steps\"><li><h3 class=\"wp-block-heading\" id=\"define-the-population-and-evidence-period\">Define the population and evidence period<\/h3><p>List directories, tenants, cloud accounts, clusters, SaaS integrations and local services. Name the accountable audit owner and document exclusions. Save the extraction method and timestamp.<\/p><\/li><li><h3 class=\"wp-block-heading\" id=\"reconcile-the-inventory\">Reconcile the inventory<\/h3><p>Compare current identities against the register. Flag unknown identities, duplicates, missing owners and accounts that the register claims were retired. Preserve the original export before editing the register.<\/p><\/li><li><h3 class=\"wp-block-heading\" id=\"review-actual-authorization\">Review actual authorization<\/h3><p>Give the business owner the purpose and dependency question. Give the technical reviewer the permission, credential and activity question. Record their decisions separately when the roles differ.<\/p><\/li><li><h3 class=\"wp-block-heading\" id=\"prioritize-findings-and-change-safely\">Prioritize findings and change safely<\/h3><p>Route suspected compromise to incident response. For ordinary cleanup, identify dependencies, schedule a change window and prepare a rollback. Don't disable a production identity on inactivity alone.<\/p><\/li><li><h3 class=\"wp-block-heading\" id=\"verify-and-close\">Verify and close<\/h3><p>After an approved change, take a fresh entitlement or account-state export. Attach it to the ticket and record who verified that the workload still works or that the retired access is gone.<\/p><\/li><\/ol>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"discovery-where-service-identities-hide\">Discovery: where service identities hide<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Active Directory and Windows.<\/strong> Review conventional domain users running services, scheduled tasks, IIS application pools, group managed service accounts and local service identities. Windows gMSAs have managed passwords, but that doesn't make their privileges or host authorization automatically appropriate. Microsoft describes gMSAs as accounts with automatic password management and simplified service principal name administration. The audit still needs the owning service, the hosts it's allowed to run on and a privilege review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Microsoft Entra.<\/strong> Inventory enterprise applications, app registrations, service principals and managed identities. Check application permissions, consent grants, directory roles and Azure resource assignments where they're in use. Microsoft's service principal sign-in logs cover nonuser sign-ins by applications and service principals; managed identity sign-ins appear in their own log category. If your tenant's retention doesn't cover the audit period, record the telemetry gap rather than calling the identity inactive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AWS.<\/strong> Inventory IAM users with long-lived keys, IAM roles used by workloads, cross-account trusts and service roles. IAM Access Analyzer can identify unused roles, IAM user credentials and permissions in its unused-access analyzer. Its findings aren't a complete list of every service identity: service-linked roles aren't analyzed for unused access, so supplement the tool with direct inventory and workload-owner review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Google Cloud.<\/strong> Enumerate user-managed service accounts by project, inspect role bindings and list user-managed keys. Google Cloud documents a service account key listing method specifically useful for audits. A key listing isn't proof that a key is still used, and a missing key doesn't mean the account lacks other authentication paths. Check workload identity federation and impersonation permissions separately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SaaS, databases and CI\/CD.<\/strong> Find integration users, API principals, deployment bots, database service users and pipeline credentials that aren't represented in the central identity provider. Ask application owners to enumerate locally configured automation. If the SaaS vendor's logs are incomplete, record what can and cannot be verified.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"reconciliation-prove-your-inventory-covers-the-sources\">Reconciliation: prove your inventory covers the sources<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treat every export as a population with its own identifier namespace. Match by platform plus immutable ID, not by display name alone. Track identities found in a source but absent from the register, records with no live object and duplicates that might represent the same workload under different names.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For each mismatch, assign a triage owner. An undocumented account should be investigated, not automatically deleted. A record marked retired while its credential still authenticates is a different finding from an account that was disabled but remains in a historical register. Make the distinction visible in the findings log.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"authorization-ask-the-owner-for-a-decision\">Authorization: ask the owner for a decision<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Send the reviewer enough context to make a meaningful choice: workload name, purpose, affected systems, effective access, recent activity, current owner and the consequence of disabling it. Ask for a clear decision: <strong>retain as-is, retain with restrictions, investigate or retire<\/strong>. Don't accept a blanket \"all good\" for an entire group when individual privileges differ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The business approver confirms whether the workload still matters. They aren't judging the permissions. The technical custodian confirms that the credential and entitlements support that workload. That's a separate call. Security or IAM can challenge exceptions, and they should. Where no owner exists, mark the identity <strong>unowned<\/strong> and escalate. Don't let the same missing field roll into another quarter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"permissions-and-credentials-what-to-test\">Permissions and credentials: what to test<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Account existence is only the first question. A valid service account can still have privileges far beyond its purpose, a credential stored in an unsafe location or access that can't be traced to one workload. The checks below help you tell those cases apart.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Audit test<\/th><th>Evidence to request<\/th><th>Finding if the test fails<\/th><th>Typical next action<\/th><\/tr><\/thead><tbody><tr><td>Effective privileges<\/td><td>Role assignments, group expansion, resource policies<\/td><td>More access than documented<\/td><td>Reduce scope with owner sign-off<\/td><\/tr><tr><td>Credential handling<\/td><td>Vault reference, certificate or key metadata<\/td><td>Unowned or unmanaged credential<\/td><td>Assign custodian and plan replacement<\/td><\/tr><tr><td>Shared use<\/td><td>Workload map, logs and deployment configuration<\/td><td>Several workloads use one identity<\/td><td>Plan separate identities where feasible<\/td><\/tr><tr><td>Activity<\/td><td>Authentication and application logs<\/td><td>No observed use or anomalous use<\/td><td>Investigate with workload owner<\/td><\/tr><tr><td>Decommissioning<\/td><td>Change record, disabled state and dependency check<\/td><td>Retired workload retains active access<\/td><td>Disable through controlled change<\/td><\/tr><tr><td>Attestation<\/td><td>Reviewer identity, decision and date<\/td><td>Approval can't be reconstructed<\/td><td>Re-run review with evidence<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"review-effective-permissions-not-just-role-names\">Review effective permissions, not just role names<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A role name like \"reader\" can hide inherited access, while a custom role may include an action the workload doesn't need. Trace direct assignments, group membership, resource policies and delegation or impersonation paths. For identities with administrative reach, the <a href=\"https:\/\/theitlead.com\/blog\/privileged-access-management-software\/\">privileged access management software guide<\/a> covers tools that vault and monitor those credentials. Review what the identity can reach, not only what its primary job calls for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a reporting job, compare the data sources it is expected to read with the databases and storage resources it can actually access. For a deployment identity, distinguish the environments it must change from environments it can merely see. If a privilege can't be justified, propose a narrower grant and test it before rollout.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"review-credentials-without-exposing-them\">Review credentials without exposing them<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Record whether authentication uses a managed identity, workload federation, role assumption, certificate, managed password or long-lived secret. Record the expiry and rotation owner only where those concepts apply. A managed identity doesn't have a human-maintained password, but its permissions and deployment attachment still need review. They're easy to overlook for that reason.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Google Cloud recommends considering workload identity federation rather than service account keys for workloads outside Google Cloud. Microsoft describes gMSAs as using managed passwords. Those approaches reduce manual secret handling, but they don't replace an owner attestation or a privilege check.<\/p>\n\n\n\n<aside class=\"ok-callout ok-callout--watch\"><p><strong>No activity is not proof of safety<\/strong> A backup integration may run only during recovery. A billing job may be seasonal. A log retention gap can make an active identity appear dormant. Confirm the workload schedule and telemetry coverage before proposing disablement.<\/p><\/aside>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"audit-decisions-and-a-practical-risk-queue\">Audit decisions and a practical risk queue<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use a small decision vocabulary that keeps downstream tickets unambiguous. It's what lets a ticket say what happens next. A spreadsheet cell that says \"reviewed\" tells nobody what should happen next, and that's how findings go stale. A decision must identify the approver, the scope of approval and any work that's still outstanding.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Decision<\/th><th>Meaning<\/th><th>Required evidence<\/th><th>Closure rule<\/th><\/tr><\/thead><tbody><tr><td>Retain<\/td><td>Purpose and access confirmed<\/td><td>Owner approval plus entitlement snapshot<\/td><td>Review date and evidence recorded<\/td><\/tr><tr><td>Restrict<\/td><td>Workload needed, access too broad<\/td><td>Owner approval plus target permissions<\/td><td>Post-change entitlement check<\/td><\/tr><tr><td>Investigate<\/td><td>Ownership, activity or purpose unclear<\/td><td>Named investigator and evidence request<\/td><td>Decision revisited after investigation<\/td><\/tr><tr><td>Retire<\/td><td>Workload no longer authorized<\/td><td>Business approval and dependency assessment<\/td><td>Disable or remove, then verify<\/td><\/tr><tr><td>Escalate<\/td><td>Suspected abuse or material exposure<\/td><td>Security incident reference<\/td><td>Incident-response process controls next steps<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Prioritize by <strong>impact and uncertainty<\/strong>. A privileged, externally reachable automation identity with no owner deserves faster investigation than a narrowly scoped identity with a confirmed owner and current evidence. But don't substitute a numeric risk score for the actual dependency review. Scores help sort a queue; they don't authorize production changes, and they're no substitute for talking to the owner.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"the-safe-retirement-sequence\">The safe retirement sequence<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Start with a dependency map: scheduled jobs, services, applications, integrations, hosts and recovery procedures that use the identity. Obtain a business decision and a change window. If the platform permits a reversible disablement, use that to test impact before permanent removal when appropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Google Cloud's service account guidance recommends disabling an account before deleting it when usage is uncertain. That distinction matters because deleting a service account and recreating one with the same name creates a different identity. For an account with suspected compromise, follow the incident-response playbook instead of waiting for an ordinary maintenance window.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the change, verify both sides: the identity no longer authenticates where access was removed, and the authorized workload still functions where it should. Attach fresh evidence, not just the engineer's note that the command completed. A rollback must have an owner and an expiration condition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-evidence-should-an-auditor-receive\">What evidence should an auditor receive?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An audit package should let a reviewer trace a selected identity from discovery to decision to verified state. It should also show how the population was built. A polished spreadsheet without original exports won't prove that nothing was left out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Population evidence:<\/strong> source system list, export timestamp, query or extraction procedure, immutable identifiers and reconciliation results. Keep excluded systems and the reason for exclusion visible; they're part of the story.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Authorization evidence:<\/strong> business purpose, approver, technical custodian, effective permission snapshot and signed or logged decision. For exceptions, include the business justification, risk owner and next review date.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Remediation evidence:<\/strong> ticket, change approval, dependency assessment, implementation timestamp, post-change entitlement export and verification result. If a planned change was deferred, show the accepted exception rather than quietly closing the finding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Control-operation evidence:<\/strong> the review campaign owner, the list of accounts assigned to each reviewer, outstanding decisions, completion timestamp and a record of follow-up. These elements show the review was actually run, not merely designed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A compact folder structure can work: <code>population\/<\/code>, <code>reviews\/<\/code>, <code>findings\/<\/code>, <code>changes\/<\/code> and <code>closure\/<\/code>. Restrict access, because even an export without secrets can reveal sensitive infrastructure relationships. The retention period should come from your organization's policy and audit requirements. It shouldn't come from a universal number in a blog post.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"which-standards-should-the-checklist-support\">Which standards should the checklist support?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CIS Safeguard 5.5 is especially direct about service account inventory and recurring authorization reviews. Its assessment specification identifies the department owner, review date and purpose as minimum fields. The same CIS page also explains how an assessor can compare the recorded inventory with enumerated service accounts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NIST SP 800-53's AC-2 account management control addresses account managers, access authorization, account monitoring and review at an <strong>organization-defined frequency<\/strong>. Don't confuse that with a universal NIST requirement to audit service accounts quarterly. It isn't one. The quarterly cadence stated here comes from CIS Safeguard 5.5. Your regulator, contract or internal policy may demand a different scope or schedule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a security control mapping, attach the exact framework edition and your organization's applicability decision. A checklist can support evidence collection, but it can't certify compliance by itself. If an auditor asks for proof of implementation, they'll care more about the review decisions and verified account state than a control number in a heading.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-often-should-service-accounts-be-audited\">How often should service accounts be audited?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For organizations using CIS Safeguard 5.5, <strong>at least quarterly<\/strong> is the stated baseline for reviewing whether active service accounts are authorized. More frequent review is appropriate when the account is privileged, business-critical, externally exposed or involved in an incident. The faster schedule is a risk-based recommendation, not a separate blanket mandate from CIS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Make reviews event-driven as well; a schedule alone won't catch every change. An application retirement, vendor offboarding, business owner departure, unexpected credential addition or major permission change should trigger a targeted check. That prevents a long gap between a material change and the next scheduled attestation. You don't want a year-old approval covering a workload that's since changed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical test of cadence isn't the calendar invite. It's whether the owner completed a decision, whether exceptions received tickets and whether the team can show the resulting access state. If those aren't visible, increasing the frequency won't fix the underlying workflow.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"where-a-lightweight-ownership-workflow-fits\">Where a lightweight ownership workflow fits<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A service account ownership review workflow can help track which account has a nominated owner, which attestation is pending and which decisions need evidence. That's a narrower job than credential rotation, directory discovery or privilege enforcement. It should sit beside those systems, not replace them.<\/p>\n\n\n\n<aside class=\"ok-product ok-wide\" id=\"the-it-lead\"><span class=\"ok-fav ok-fav--md ok-fav--ours\"><img src=\"\/blog\/wp-content\/uploads\/opskit\/fav\/itl.svg\" alt=\"\" width=\"24\" height=\"24\" loading=\"lazy\" decoding=\"async\"><\/span><div><p class=\"ok-product__eyebrow\">What these tools don&#x27;t answer<\/p><p class=\"ok-product__head\">Know who owns every service account, and when it was last reviewed.<\/p><p>The IT Lead imports service accounts from CSV, nominates owners, collects their attestations and keeps a review trail an auditor can follow.

A different framework or internal risk policy may require additional checks or a faster cadence for sensitive accounts.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-4\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can an unused service account be deleted immediately?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>No, not safely on inactivity evidence alone. Confirm the workload, logging coverage, dependencies and change approval first. When appropriate, test reversible disablement and verify impact before permanent deletion.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-5\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Who should approve service account access?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The business owner should confirm that the workload is needed, while a technical custodian checks permissions, authentication and dependencies. Security or IAM should review exceptions and high-risk grants.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-6\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What evidence proves the audit was completed?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Retain the original account exports, reviewer identities and decisions, entitlement snapshots, exception approvals, remediation tickets and post-change verification. Those records let an auditor trace the decision back to the source, and they're what an auditor will ask for.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"final-takeaway\">Final takeaway<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A reliable service account audit isn't a list of identities with a checkmark. It's a repeatable way to reconcile the population, assign accountability, inspect access, make decisions and prove that risky access was handled. Start with the register and checklist above. Then make the review evidence easy for the next IT lead to reproduce, so they're never guessing who approved what.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Use this service account audit checklist to verify owners, permissions, credentials and activity, with a copyable register and evidence closure steps.<\/p>\n","protected":false},"author":1,"featured_media":102,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[],"class_list":["post-101","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-it-security"],"_links":{"self":[{"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/posts\/101","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/comments?post=101"}],"version-history":[{"count":1,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/posts\/101\/revisions"}],"predecessor-version":[{"id":103,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/posts\/101\/revisions\/103"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/media\/102"}],"wp:attachment":[{"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/media?parent=101"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/categories?post=101"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/theitlead.com\/blog\/wp-json\/wp\/v2\/tags?post=101"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
