Endpoint Privilege Management (EPM): Removing local administrator rights

Why remove local admin rights and what goes wrong

A local administrator account on a workstation is not a convenience — it’s the "keys to the kingdom." If a user account is compromised, an attacker with admin rights can quickly persist on the system, disable protections and move across the network.

Removing local admin rights usually shows fast and visible benefits: fewer infections from phishing and malicious attachments, fewer unauthorized software installs and "shadow" configurations, and clearer visibility into who got elevated rights and why. It makes audits and incident investigations easier and reduces the chance that a single user accidentally "breaks" their workstation.

The problem is that many companies have long solved operational issues by the rule "give everyone admin." Applications and processes get used to it. When rights are revoked, hidden dependencies appear: an app needs to write to protected folders, install a driver, change system registry keys or update via an old installer.

This hits specialized software and peripherals hardest. In finance it's often client‑bank software, crypto providers, printing and signing tools. For engineers — CAD, plugins, licensing and device drivers. In healthcare — diagnostic software, scanners, wristband printers and integrations with medical systems where updates are irregular and often installed "off process."

Typical breakages after privilege removal fall into several scenarios:

• updates don’t install because the installer needs access to system components;
• legacy programs don’t run because they write to Program Files or HKLM;
• drivers and services fail to install (printers, tokens, special equipment);
• plugins and extensions that users used to install themselves stop working.

If you keep giving admin to everyone, risks don’t go away: malware can disable protection, collect passwords, change policies, install remote access and wait for an opportunity. So instead of "either admin or nothing" you need a controlled compromise. Endpoint Privilege Management (EPM) grants elevation only for a specific action, under rules and with audit logs — not permanently.

What EPM is in simple terms

Endpoint Privilege Management (EPM) is a way to provide admin rights on a computer not "forever," but only for a specific action and according to clear rules. A user works as a normal employee without local admin rights, but when needed can run a driver installer, an update or a particular application with elevated privileges.

The idea is simple: remove permanent privileges without stopping work. Instead of "everyone has admin because it’s easier," you get a model where rights are granted for a limited time, to a specific program or task, with logging and the ability to audit.

How EPM differs from PAM and regular UAC

UAC in Windows is a popup that asks "Allow?" It doesn’t explain who or why permission was granted and is poorly suited for company‑wide control.

PAM (Privileged Access Management) is usually about administrator accounts and access to servers, network equipment and databases. EPM focuses on endpoints (workstations and laptops) and everyday elevation requests.

Where EPM delivers the most value

EPM is most often implemented where there are many standard workstations and audit/InfoSec requirements: office Windows devices, terminal environments and VDI, and protected segments in government, finance, healthcare and education.

EPM does not solve all security problems. It doesn’t fix application vulnerabilities or strengthen weak passwords. If an application is insecure, running it as admin only accelerates the impact.

A good EPM answers three practical InfoSec questions: who elevated privileges, why, and whether it was per policy or via an ad‑hoc approval.

Practical approaches that work in organizations

Almost nobody does a "remove everyone’s rights in one day" operation. In practice, approaches that preserve workflows and gradually restore control work best. EPM systems typically combine several models.

The first approach — remove local admin from everyone and allow targeted elevation — gives the most predictable risk reduction but requires well‑tuned rules and solid support.

The second approach — keep local admin only for those who truly need it and tightly control their actions: logging, restrictions, and prohibitions on dangerous scenarios — is used where there are many engineers, labs or legacy apps. It’s important to set deadlines and criteria up front, otherwise the exception list will grow forever.

A typical role picture in practice looks like this:

• office staff operate without admin; elevation happens only by rule;
• IT and engineers get temporary rights or specific roles, but with audit trails;
• critical workstations (POS, medical devices, production equipment) follow strict rules and minimal manual requests;
• contractors receive JIT (temporary) elevation only for a specific task.

Rule‑based elevation relies on how precisely you describe "what is allowed." The most practical criteria are the application and its publisher (digital signature), the file path, and for the most sensitive cases — the file hash. A hash is precise but adds maintenance: when the program updates, the rule must be updated.

JIT and temporary rights are useful when the task is rare and clear: install a driver, update specialized software, perform diagnostics. A 15–60 minute window reduces the risk that admin rights will remain "forever."

If you use a request process for elevation, don’t turn it into a half‑day email thread. The request should include a minimum:

• what will run (file or application);
• why (short business reason);
• how long the rights are needed;
• which device and which user;
• who approves (application owner, InfoSec or IT per the matrix).

Example: an accountant needs to update a reporting module that is signed by a known publisher but installs to a nonstandard path. It’s better to create a rule by publisher and application name once than to grant admin rights to the user every quarter.

Preparation for deployment: inventory and pilot

Before removing local admin rights, you must understand two things: where they are actually used and what will break if you remove them. Without this, EPM quickly turns into endless exceptions and complaints.

Start with an inventory of devices and users. Split the estate into clear groups: office, branches, remote workers, laptops used traveling. Separate segments like finance, engineering and call center. Consider not only device type but also management method (domain, Intune, standalone PCs), because deployment of an agent and policies depends on that.

Next, collect the top tasks that "require admin" today. Usually these are driver and update installs, VPN clients and crypto providers, printer and scanner setup, running utilities that write to Program Files or the system registry. A useful method: take tickets from the past 1–2 months and mark the 20 most frequent reasons for remote IT sessions.

Classify software in parallel: corporate (standard set), role‑specific, custom and legacy. For legacy software decide in advance: replace it, isolate it, or allow controlled elevation only for a specific process.

The pilot group should be small but "noisy": 20–50 people from different roles and locations. Define success criteria before start:

• share of tasks completed without granting local admin;
• number of support requests per user;
• list of apps requiring elevation rules;
• quality of InfoSec reports (who, what, when and why elevated);
• IT response time to new requests.

For example, in a company with a head office and several branches a pilot often includes finance, the service desk and one branch: you’ll quickly see both heavy apps and remote support challenges.

Step‑by‑step plan: remove admin and keep things working

Start small and measurable: pilot group, clear rules and fast rollback. This way you remove local admin rights without turning user and IT work into endless tickets.

A practical sequence that usually works:

1. Choose a pilot (e.g., 30–50 users from finance, support and several "heavy" engineers). Remove local admin and enable basic rules: allow standard tasks, block unknown installers, and restrict critical system changes.

2. Collect "first pains" for 3–7 days and add permissions for common scenarios: corporate updates, printer drivers, VPN client, remote support agent. Don’t "allow everything": grant elevation narrowly — to a specific application, path, publisher or hash.

3. Configure a privilege request and a simple approval flow. Example: the user clicks "Request," provides a reason, the ticket goes to Service Desk, and approval takes up to 15 minutes in business hours. For critical roles you may allow self‑approval but with a short expiry and mandatory justification.

4. Turn on logging and verify that reports are readable for InfoSec: who, when and what ran with elevation, which rules fired, where denials occurred. At this stage hidden admin activities often surface.

5. Expand coverage in waves by departments and document exceptions: who, why, for how long, and what compensating controls exist.

Example: a designer needs a plugin that installs only as admin. Instead of restoring admin rights, add a rule for the installer from a specific publisher and allow elevation only for installation. Other installers remain blocked.

Configuring elevation rules without creating security holes

The main idea of EPM is simple: elevate an action, not the user. The more precise the rule, the lower the chance it becomes a "hidden admin."

Start with a whitelist: which applications really need admin rights and why. It’s safer to allow one required installer than "everything from this vendor."

The more precise the rule, the safer it is

The most reliable option is to allow a specific application and version (or even a file hash). This fits installers, agent updates and maintenance utilities. The downside: each update may require rule adjustments.

Rules by publisher and digital signature are usually easier to maintain: signed apps from one vendor will work without manual changes. But signatures must be valid and the trust chain verifiable. If a publisher has many products, you may accidentally allow more than intended.

Consider workstation pain points separately: drivers, printers, crypto providers, tokens, browser plugins. Often they need elevated rights only during installation, not daily operation. Then create rules that allow elevation only for the installer and only from a trusted location (for example, a corporate software catalog).

In‑house tools and preventing abuse

For unsigned internal tools, avoid broad exceptions. Typical solutions: sign them with a corporate certificate and allow by publisher, temporarily allow by hash during transition, or package them as MSI and control installation through an approved package manager.

To prevent rule abuse, often elevation is blocked for generic tools (cmd, PowerShell, regedit). Also limit child process creation during elevation and avoid allowing "any command line arguments" when they can be used to alter behavior.

Reporting and audit for InfoSec: what to collect and how to read it

After removing local admin rights InfoSec needs not just events but context: who requested elevation, why, on which device, and what happened afterwards. EPM usually collects this automatically, but reports are useful only if they answer investigation questions.

Events and metrics that really matter

A basic event is: "a user attempted an action that requires elevation." Capture the full chain: request, decision, execution and result. Useful periodic reports show repeated patterns: where admin is requested most often, which apps frequently fail without rights, and why requests are denied.

Example: an accountant repeatedly tries to install a crypto provider or printer driver. If legitimate, create a targeted rule and the problem disappears. If dozens try to install the same "PDF accelerator," it’s a sign of shadow software and a reason to talk to the department.

Regular control reports are short: top apps by request volume, denial rate, average approval time, devices with unusually high request counts and users who request installations more often than others.

Minimum audit fields for investigations

To reconstruct an event you need at least:

• Who: account, group, department (if available), and who approved (or which policy allowed automatic elevation).
• Where: device name, type (laptop/desktop), site or location, IP (if relevant).
• When: exact timestamp and elevation duration.
• What: process or installer name, file path, publisher/signature, hash (if available), version.
• Outcome: allowed/denied, rule or reason for denial, what was executed after elevation.

Preparing for audits

Store logs predictably and per policy, otherwise an auditor will find "events exist but no evidence." Define retention periods, access rights to logs and the export process in advance.

A practical minimum: centralized log collection (for example, into your monitoring/analytics system), retention according to industry and internal rules (with separate retention for critical incidents), role separation (who views, who exports, who approves deletions), report templates for audits and regular exception reviews.

With this, reports stop being a checkbox and become a working tool: they help reduce exceptions, find shadow installs and prove that privilege control is in place.

BeyondTrust, CyberArk and Microsoft EPM: choosing for your use case

Choosing EPM usually comes down to how you’ll live with the solution daily: how quickly you grant elevation, how you investigate incidents and how you present clear InfoSec reports.

Differentiators that matter:

• deployment and management (cloud/on‑prem, infrastructure requirements, agent updates);
• rule flexibility (application, publisher, hash, launch parameters);
• user requests (self‑service, approval UX, how long support takes);
• reporting and audit (elevation events, denials, run attempts, SIEM export);
• integrations (AD/Azure AD, Intune, Service Desk, remote support tools).

BeyondTrust is often chosen for mature elevation scenarios and fine control. In a pilot check how easy it is to maintain whitelists (by publisher and signature), how temporary elevation works and how much manual work admins face when apps change.

CyberArk is considered when an organization already uses CyberArk or has strict privilege control and audit requirements. Verify how exceptions are handled and how fast you can roll back a rule if it breaks business processes.

Microsoft EPM in Intune fits where devices are already managed via Intune and you prefer fewer consoles. But evaluate rule flexibility and reporting limits in advance: sometimes additional measures are needed for InfoSec analytics and approval workflows.

TCO is easiest to calculate for a concrete scenario: "1000 endpoints, 30 typical exceptions, 10 requests per day." It includes licenses, rule maintenance time, Service Desk load and integration costs. If you can’t estimate internally, a systems integrator with EPM experience can help with pilot, effort estimation and operational process setup. In Kazakhstan such projects are often implemented together with teams like GSE.kz, which can also handle workstation and server refreshes in a single support environment.

Common mistakes when removing admin rights

The most frequent cause of failure is not "user resistance" but wrong settings and lack of process. EPM is flexible, but with a poor start you either open too many rights or break business scenarios.

Frequently seen errors

Problems usually stem from recurring decisions:

• overly broad rules like "allow elevation for all apps from this publisher";
• ignoring legacy apps that write to Program Files or system registry branches;
• exceptions without expiry and without an owner (temporary permissions accumulate into dozens of "permanent" allowances);
• piloting only with IT (you’ll discover issues in finance, engineering, contact center and healthcare later);
• disabled reports and audit (InfoSec can’t see what changed and where risks grow).

How to avoid these traps

Imagine a finance plugin for signing that IT doesn’t use in daily work. If you test only on admins, on rollout the signing will "stop" and trust in the project will collapse.

Practical measures that help:

• make rules as precise as possible: app, version (or range), path, hash, specific actions;
• for exceptions require a request form, owner, reason and expiry date plus mandatory review;
• pilot across roles: pick 3–5 groups with different tasks and collect their critical apps in advance;
• enable baseline reports for InfoSec: who requested elevation, what was allowed, what was blocked, and which devices are most noisy.

This preserves functionality and lets you show clear gains: fewer permanent admins and more controlled, explainable elevations.

Quick checklist before company‑wide rollout

Before rolling EPM out to all users, ensure you’re not promoting a raw pilot to production. Most failures are due to unclear rules and weak early support rather than the tool itself.

A checklist you can run through in an hour with InfoSec and IT:

• Users segmented by groups: who can lose admin immediately, who needs rare elevation, and who has a justified permanent need.
• Request process agreed: how to submit, who approves, how long elevation lasts, and who owns the decision. Elevation lifetime is fixed.
• Starter rules prepared for typical tasks: install/update corporate apps, drivers, plugins, VPN clients, remote support tools. Better 5–10 precise allowances than one broad "allow all for the department."
• Logging enabled, reports readable and exportable: who requested elevation, what ran, on which machine, on what grounds, and what the outcome was.
• Rollback plan and boosted support for rollout: who and how will restore access in case of a critical failure, the expected reaction window in the first 3–5 business days, and where users should report an immediate break.

A practical test before rollout: pick 3–5 employees from different departments and observe their workday without local admin. If you must permanently grant admin at least twice, rules are not ready.

Next steps: scaling and process support

After the pilot, don’t flip the switch for everyone — expand coverage in waves. EPM works well when you track metrics each time: number of elevation requests, denials, incidents, and processing time. Define SLAs for IT and InfoSec so users know when they’ll get help and the team isn’t overwhelmed.

A simple scaling plan helps: one department first, then teams with similar apps. For each wave set readiness criteria (critical exceptions closed, instructions and owners in place), a change window and a clear rollback. Communicate to users with a short message: what changes and where to get help.

Then routine begins — the activity that delivers security. Monthly reviews of requests and exceptions help: which apps often require elevation, where permanent allowances can be removed, and which rules are stale after updates. A sign of maturity is when every exception has an expiry date and an owner.

Over time, complement EPM with measures that reduce the need for admin rights and speed risk mitigation: application allow/deny lists, patch management for OS and key apps, network segmentation and endpoint standardization (images and baseline software).

If you lack staff or need 24/7 coverage, involve a systems integrator: they can finalize policies, set up approval workflows and reporting for InfoSec, and then provide ongoing support. This is especially useful when you’re also refreshing workstations and servers and need a single party to keep operations and security aligned.
