To ensure the security of systems, restricting administrative privileges is a crucial strategy and an essential component of the Australian Government’s Essential Eight recommendations.
By restricting admin roles and removing local admin rights, users are prevented from making significant changes to their operating system configurations, bypassing critical security settings, and accessing sensitive data. Additionally, domain administrators are prevented from controlling entire network domains, including all workstations and servers within the network.
Why remove local admin rights and restrict admin privileges?
Malicious actors often exploit vulnerabilities in workstations and servers by using malware to elevate privileges, spread to other hosts, hide their existence, persist after reboot, obtain sensitive data, or resist removal efforts.
However, by restricting admin privileges, these risks can be effectively combated, as it becomes more challenging for malicious actors to operate. Moreover, environments where administrative privileges are restricted are generally more stable, predictable, and easier to manage.
Restricting admin privileges: what works and what doesn’t?
Ineffective methods for restricting admin privileges
Companies often think they have this area covered, undertaking certain actions that may appear to protect their system and user administrators, when in fact they don’t go far enough. This can lead to a false sense of security that puts an organisation at risks. These ineffective actions include;
- Minimising the total number of privileged accounts.
- Temporarily allocating administrator privileges to user accounts.
- Placing standard user accounts in user groups with administrative privileges.
So, keep this in mind when planning your strategy, and reach out to us at Cloud Connect WA if you have any questions or concerns about your current approach.
Effective methods for restricting admin privileges
To effectively restrict administrator privileges, organisations should take the following steps:
- Identify the tasks that require admin privileges to be performed.
- Validate which staff members are required and authorised to carry out those tasks as part of their duties.
- Create separate attributable accounts for staff members with admin privileges, ensuring that their accounts have the least number of privileges needed to undertake their duties.
- Regularly revalidate staff members’ requirements to have a privileged account, or when they change duties, leave the organisation, or victims of a cybersecurity incident.
Additionally, companies can go one step further by strictly limiting a privileged administrator’s access to the internet – to only what is required to undertake their duties.

Frequently Asked Questions
Why should Perth businesses restrict administrative privileges?
Restricting administrative privileges is a core component of the Australian Government’s Essential Eight security framework. In Perth’s evolving cyber landscape, removing local admin rights prevents users from accidentally bypassing security settings or accessing sensitive data. This strategy ensures that environments remain stable, predictable, and significantly harder for malicious actors to exploit.
How does restricting admin rights stop cyber attacks?
Malicious actors often use malware to elevate privileges, hide their presence, and resist removal. By restricting admin roles, you break the attack chain; it becomes much more difficult for an intruder to spread to other hosts or make unauthorized changes to your operating system configurations.
What are common mistakes when trying to restrict admin access?
Many organizations in Perth fall into a false sense of security by using ineffective methods. Simply minimizing the total number of accounts, temporarily granting admin rights to standard users, or placing standard accounts in “admin-privileged” groups does not provide sufficient protection and can leave your network vulnerable to exploitation.
What is the most effective way to manage admin privileges in the workplace?
Effective management involves identifying specific tasks that require elevated rights and validating which staff are authorized to perform them. Organizations should create separate, attributable accounts with the least privilege necessary, and strictly limit those accounts’ internet access to only what is required for their duties.
How often should privileged accounts be reviewed?
Privileged accounts must be regularly revalidated. At Cloud Connect WA, we recommend audits whenever a staff member changes duties, leaves the organization, or if there is any suspicion of a cybersecurity incident. This ensures that access rights always align with current operational needs and security standards.
