Sometimes during the course of helping people and companies with best practice security – you’ll get push back on certain items. One item we have run into where smaller companies can give push back is having their employees have local admin access on workstations.
Running a computer with local administrator rights as a regular practice can pose significant risks and is generally not recommended for several reasons:
- Security Vulnerabilities: When you’re logged in as an administrator, any malware or virus that may infect your computer could potentially gain the same level of access. This means that malware could install itself, access sensitive data, modify system files, and spread to other computers on the network with relative ease.
- Risk of Unintentional System Changes: With administrator rights, it’s easy to unintentionally change system settings or install software that might negatively affect the computer’s performance or stability.
- Software Installation Risks: Users with administrator rights can install any software, which can be a risk if the software is malicious or not properly vetted. It could potentially introduce security vulnerabilities or stability issues.
- Reduced Control Over IT Environments: In an organization, allowing all users to run with administrator rights can lead to a lack of standardization and control over the IT environment, making it harder to manage and secure.
- Compliance and Auditing Issues: Many regulatory frameworks require that least privilege principles be applied - meaning users should only have the access necessary to perform their job. Running as an administrator goes against this principle and can lead to compliance issues.
- Potential for Greater Impact from Cyber Attacks: If a user with administrator rights becomes the victim of a phishing attack or other form of social engineering, the attacker could gain control over the entire system, leading to more significant damage than if the user had limited rights.
To mitigate these risks, it’s recommended to operate with the least privileges necessary for your regular tasks and only use administrator accounts when necessary for specific administrative tasks. This approach, known as the principle of least privilege, significantly reduces the risk of accidental system misconfigurations, unauthorized access to sensitive data, and the spread of malware.

Subject: Acknowledgment and Acceptance of Risks Associated with Local Administrator Access
Dear [Recipient’s Name],
As part of our ongoing commitment to maintaining a secure and efficient IT environment, we are addressing the inherent risks associated with users having local administrator rights on their workstations.
It is essential to understand that this level of access can potentially expose our network and data to increased security risks. These risks include, but are not limited to, the following:
-
Increased Vulnerability to Malware and Viruses: Local administrator rights can allow the installation of software, including potentially malicious programs, without restrictions.
-
Unintended System Changes: With administrator privileges, significant and potentially harmful changes can be made to the system settings, which might affect not only your workstation but also other systems on our network.
-
Data Breach Risks: Elevated privileges can lead to accidental or intentional access to sensitive or confidential company data.
-
Compliance Risks: Certain regulatory frameworks require strict controls over administrative access, and failure to comply can result in penalties.
By signing this letter, you acknowledge that you have been informed of these risks and the responsibilities that come with having local administrator rights. You agree to adhere to the following conditions:
- Use administrative privileges only when absolutely necessary for job functions.
- Ensure all software installations and system changes are in line with company policy.
- Avoid accessing or modifying system settings or data that are not directly related to your job responsibilities.
- Report any unusual system behavior, security incidents, or potential breaches immediately to the IT department.
Please understand that failure to adhere to these guidelines can result in revocation of your local administrator rights and other disciplinary actions as deemed appropriate by [Company/Organization Name].
Your cooperation in maintaining the security and integrity of our IT environment is greatly appreciated. Please sign below to indicate your understanding and acceptance of these terms.
Sincerely,
