Prevent privileged accounts from accessing internet, email, and web services
Block admin accounts from internet and email to enhance security.
Plain language
This control ensures that users with special access to your computer systems, known as privileged accounts, can't use the internet, email, or visit websites. This matters because without these restrictions, a hacker could take over these accounts and access sensitive information or cause harm to your business.

Official control statement
Privileged accounts (excluding those explicitly authorised to access online services) are prevented from accessing the internet, email and web services.
Why it matters
Admin account internet access can lead to credential theft via phishing, risking total organisational compromise.
Operational notes
Regularly audit privileged accounts and enforce blocks on web, email and internet access, allowing only explicitly authorised exceptions.
Implementation tips
- The IT team should create a list of all privileged accounts in the organisation and review which ones truly need internet access.
- The system administrator should configure the network firewall to block internet access for privileged accounts, except for those specifically authorised.
- Security officers should conduct regular reviews of privileged accounts to ensure compliance with internet access restrictions and update authorisations as roles change.
- The IT team should set up alerts for any attempts by privileged accounts to access internet services, using network monitoring tools.
Audit / evidence tips
- AskHow are privileged accounts prevented from accessing the internet, email, and websites?
- GoodThe firewall rules should clearly show blocks for internet traffic for all privileged accounts except those with explicit authorisation
- AskWhich privileged accounts have been authorised to access the internet and why?
- GoodA limited list with clear, justified reasons for access and records of formal approvals
