Why admin rights matter

What administrator rights actually allow

An administrator account on a computer can install software, change security settings, turn off antivirus, read other users' files and create new accounts. In a small office it is common for everyone to be a local administrator, usually because it was easier when the computers were set up or because one application once needed it. Over time this becomes the default and nobody questions it.

The problem is that anything the user runs inherits those rights. If someone opens a malicious attachment while signed in as an administrator, the malware gets the same power. It can disable protections, install tools that survive a restart and look for ways to spread to other machines. Ransomware operators rely on this, because admin rights make every later step of their attack faster and easier.

The principle of least privilege

Least privilege means each person and system has only the access needed to do the job, and nothing more. For most staff, that means a standard user account on their computer, access to the shared folders their role requires, and no ability to change system settings. It is one of the foundational controls recommended by the Canadian Centre for Cyber Security.

The same principle applies in the cloud. In Microsoft 365, only a few people should hold global administrator rights, and they should use separate admin accounts that are not used for email or web browsing. Day-to-day work happens in a normal account, and admin accounts are used only when admin tasks are needed.

Handling the exceptions

Removing admin rights often surfaces a few applications that seem to need them. Many of these can be fixed by adjusting folder permissions or installing a newer version. Software installations can be handled through a central deployment tool or a self-service company portal, so staff can install approved programs without holding admin rights themselves.

For the remaining cases, privilege management tools can allow a specific program to run with elevated rights while the user stays a standard user. Another option is a temporary elevation process, where the help desk grants admin access for a short window and it is removed automatically afterwards. Either approach keeps the convenience while removing the standing risk.

• Fix permissions instead of granting admin
• Use a company portal for approved software
• Elevate specific applications, not people
• Make temporary access expire automatically

Rolling out the change

Explain the change before you make it. Most staff accept it once they understand it protects them and the business, and that installing approved software will still be easy. Start with a small group, keep a list of the requests that come in, and solve the common ones before moving to everyone. Expect a burst of help desk tickets in the first two weeks, then a sharp drop.

Leaders should follow the same rules. An owner or manager with permanent admin rights on a laptop that also reads email is a valuable target, and making an exception for seniority undermines the message for everyone else. When the owner works as a standard user without complaint, the rest of the team usually follows. Visible leadership support is often the difference between a smooth rollout and months of pushback.

Review access regularly

Access tends to grow over time. People change roles and keep old permissions, contractors finish projects but keep their accounts, and someone is made an administrator to fix a problem and never removed. Schedule a review at least twice a year covering admin accounts, shared folder permissions, and access to finance and HR systems.

Ask each manager to confirm what their team actually needs, and remove what they do not. Pay special attention to accounts that have not signed in for months, which are a common way in for attackers because nobody notices them being used. Disable inactive accounts first and delete them after a set period if nobody objects. Keep a simple record of each review so you can show it to insurers or auditors.
