Secure Admin Access: A Step-by-Step Privileged Access Plan

To secure admin access means to limit who can use administrator and service accounts, to show who is using them, and to keep a record of what they do. Those accounts can change settings and also reach other people’s data. This guide is for an IT manager or owner at a mid-size firm in India or the GCC. It covers workforce administrator accounts and service accounts, but not a website’s log-in page or the settings of one PC. It has eight steps, each with a decision and a yes/no check. The steps, their order and the checks are Signisys’ own working method.

NCSC’s 10 Steps identity page (UK; published and reviewed 11 May 2021, version 1.0; written for cyber security professionals) lists what to cover for administrative accounts, and it is not a numbered how-to. The eight steps here put those items, and others, in an order of Signisys’ own; H2 2 shows where each NCSC line sits.

For a plain definition of privileged access, see the glossary’s definition of privileged access; its short start list also begins with finding accounts and ends with a review, and these steps add what lies between.

Secure Admin Access in Short: Eight Steps in Order

The steps and their order are Signisys’ own, and the first step needs only what each system already shows. If a step has no recorded yes, it counts as not done. These eight steps are the short answer to how to secure admin access if a firm has not started.

Secure Admin Access and the Sources: What NCSC Says, and What Is Ours

NCSC’s Introduction to identity and access management (UK; published and reviewed 22 January 2018, version 1.0; written for cyber security professionals, large organisations and the public sector) calls privileged user management “the additional processes and controls you should put in place to safeguard the most sensitive operations in the system”. The order here is Signisys’ own, as of November 2026.

Steps 1, 4 and 5 are Signisys’ own and are not drawn from either NCSC page. NCSC’s Introduction adds that some of its privileged-user techniques “can have a detrimental effect on usability, and may be unpopular with privileged users”.

Steps 1 to 3: Know the Accounts, Then Cut the Rights

These three need lists and decisions, but no purchase. In our view, if these three are missing, the later steps to secure admin access have nothing firm to work on. Signisys’ reasoning for the order: Steps 1 and 2 find and name the accounts before Step 3 cuts their rights.

Secure Admin Access, Step 1: Ask Each System for Its Admin and Service Accounts

Ask each system, application and device in scope for the accounts that can change settings or reach other people’s data, and put the answers in one place. An administrator account means an account that can change settings or reach others’ data, while a service account means an account that a program or system uses to sign in, with no person at the keyboard.

Keep one list with one named owner, one column for the system and one for the kind of account, such as named, shared, service or unused. Shared and unused accounts can be missed when you read one system’s list at a time. If a system gives no list, write it down as “not yet checked” instead of skipping it.

Decision: which systems are in scope for the first pass, and who asks each one.

Leave until later: deciding what each account may do, which is Step 3.

Step 2: Put Each Admin Login Under One Name

Each admin login belongs to one named person. The separate everyday account and the second check on an administrative account are set up as in the earlier identity set-up guide, which this step does not repeat.

A second check, also called multi-factor sign-in, means a password plus a second proof, such as a code or a security key. A login that several people share gets a named owner now, or the firm replaces it (our view).

Decision: who becomes the named owner when several people share a login, and who approves its replacement.

Leave until later: second checks for people without admin rights.

Step 3: Give Rights for a Task, Not for Good

For each administrator role, write down the tasks it exists for, and give only the permissions those tasks need. Give anything wider for one stated task, and take it back when the task ends.

NCSC’s 10 Steps page says to “only use accounts with full privileges (like domain admin, global admin, or cloud admin accounts) when absolutely necessary”, as part of a tiered model for administrative accounts. The number of full-privilege accounts the firm keeps is its own decision, and this guide gives no number. If a system gives no way to grant a right for a limited time, a person withdraws it and writes down the date. The order of Steps 1 to 3 is our view, not a finding.

Decision: which tasks justify a full-privilege account, and who approves a wider right when a task needs one.

Leave until later: time-limited access by tool. If you are weighing a dedicated tool, that is a separate decision, and your systems’ own documentation shows what they already allow.

Steps 4 to 6: Service Accounts, Emergency Access and Admin Devices

These three steps to secure admin access deal with the accounts and devices that sit outside the normal person-and-password pattern, and each asks for a decision from a person. Signisys’ reasoning for the order: they follow the base, and each has a list and an owner to attach to.

Secure Admin Access, Step 4: Give Each Service Account an Owner

When you find a service account in Step 1, record what it is for and who owns it. Switch off an account with no purpose and no owner, but ask the likely owner first.

The same record shows where the account’s secret sits and who can read it. Shared logins that systems depend on also get the same treatment. This step is Signisys’ own; it is not drawn from NCSC. For the wider subject, see machine and agent accounts.

Decision: who owns an account when its original owner has left, and what the firm does when switching an account off could stop a system.

Leave until later: replacing a stored secret with another method, which is a design choice for a later article.

Step 5: Set Up Emergency Access

Emergency access, also called a break-glass account, means a way in kept for when the normal admin accounts or the second check fail. Set it up, protect it and test it before you need it.

The account stays out of everyday use unless the normal ways in fail. Store its secret where more than one named person can reach it during an emergency, and note who. Step 7 also records and reads any use. The number of emergency accounts is the firm’s decision, and this guide gives none. This step is Signisys’ own and is not drawn from NCSC.

Decision: who may use it, who must hear when someone uses it, and who tests it.

Leave until later: automated alerts on its use, which depend on Step 7.

Step 6: Do Admin Work From a Protected Device

Start administrator tasks from a device set aside for them, or from a jump host, while email and web browsing stay off it. A jump host means a controlled server that administrators connect through.

NCSC’s 10 Steps page gives separate devices or a “browse-down approach” as examples of keeping everyday and administrative accounts apart, and says to “consider blocking any unnecessary web and email access on those devices”. It adds that these considerations “may also apply to other users with greater accesses”, for example people who approve payments. NCSC’s Introduction says a browse down approach “should be used to perform functions in less trusted environments from within the more trusted one”. While this guide names no platform, check this step against your provider’s documentation.

Decision: a set-aside device or a jump host, and who may use it.

Leave until later: network segmentation (outside this guide).

Steps 7 and 8: Records and Reviews

The last two keep the first six in working order. Recording and review are how a team can show later that the work held. In our order these come last: there must be accounts and rights before there is anything to record and review.

Secure Admin Access, Step 7: Record Admin Activity and Watch for Changes

Send admin sign-ins and changes to one place that someone reads, and choose which events raise an alert.

NCSC’s 10 Steps page says: “Ensure authentication and authorisation events are logged and monitored for suspicious behaviour”. It adds that indicators of malicious behaviour “could include login attempts that fail the second step of MFA” and “attempts from unexpected geographical areas”. A new administrator grant is our example of an event worth an alert, and use of the emergency account (Step 5) is another.

Decision: who reads the record, and what the firm does when an alert fires.

Leave until later: recording what an administrator does inside a session, which depends on your systems and is a tool decision.

Step 8: Set the Review and Its Owner

Name the person who reviews administrator rights and write down when the first review happens.

In its advice on privileged accounts, NCSC’s 10 Steps page says: “Review user accounts and systems for unnecessary privileges on a regular basis, and ensure privileged accesses are revoked when no longer required.” The page gives no interval, and neither does this guide; the firm sets its own and writes the reason beside it. The reviewer compares against the Step 1 list when checking rights.

Decision: who reviews, who covers when they are away, and the interval.

Leave until later: a full review method, which a later article covers.

A Secure Admin Access Example: A Small Firm, Illustrative

This example is illustrative only and not a Signisys client, and it uses no numbers and no durations.

In Step 1 a small firm finds a service account that no one recognises. The Step 4 check fails when the account has no owner. A person asks around, finds the owner and records the account’s purpose, and the check passes when it runs again. In Step 5 the first test of the emergency account fails: the stored secret is out of date. When the firm replaces the secret and repeats the test, it passes. In Step 6 the firm finds that people have been starting admin work from an everyday laptop. When the firm picks a set-aside device, the check passes.

A failed check sends the reader back one step, not forward, while a pass shows only the result on the day the check ran.

What This Guide Leaves Out, and When to Ask for Help

This guide stops at a working set of eight steps for administrator and service accounts. It also leaves out website log-in pages, the settings of one PC, why attackers want admin accounts, a scored checklist, tool choice, network segmentation, customer sign-in, supplier access and anything a regulator requires. For the wider picture, see the privileged accounts use case.

Outside help is worth having when any of these three applies:

• Admin accounts that nobody can find or match to a person.
• A service account that would break a system if you changed it.
• Cloud administrator roles, where the steps need checking against the provider’s own documentation (our advice, not a finding).

Signisys helps organisations control who can access what, including privileged access for administrators and critical systems, with the exact scope agreed for each engagement. See our solution, Identity and Access Management (IAM), and our service, Cybersecurity Services.
