UAC is designed to prevent unauthorized changes to your PC. To configure UAC settings, navigate to:

Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options

Prioritize the following settings for a more secure environment:

  • User Account Control: Admin Approval Mode for the built-in Administrator account: Enabled
  • User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop: Disabled
  • User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode: Prompt for consent
  • User Account Control: Behavior of the elevation prompt for standard users: Prompt for credentials
  • User Account Control: Detect application installations and prompt for elevation: Enabled
  • User Account Control: Only elevate executable files that are signed and validated: Enabled
  • User Account Control: Only elevate UIAccess applications that are installed in secure locations: Enabled
  • User Account Control: Run all administrators in Admin Approval Mode: Enabled
  • User Account Control: Switch to the secure desktop when prompting for elevation: Enabled
  • User Account Control: Virtualize file and registry write failures to per-user locations: Enabled

Pro Tip: Be prepared for more frequent UAC prompts, which act as your first line of defense.

Step 2: Secure Password Requirements

Step 2: Establish Robust Password Policies

To enhance password security across user accounts, access:

Computer Configuration -> Windows Settings -> Security Settings -> Account Policies -> Password Policy

Implement these configurations:

  • Enforce password history: 8 or above
  • Maximum password age: between 30-60 days
  • Minimum password length: 12 or more
  • Password must meet complexity requirements: Enabled

Pro Tip: Encourage users to change their passwords regularly to further secure their accounts.

Step 3: Disable the Guest Account

Step 3: Eliminate Guest User Access

To remove the potential threat posed by the guest account, navigate to:

Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options

Then disable the Accounts: Guest account status policy to prevent unauthorized access.

Step 4: Enable Account Audit Policies

Step 4: Activate Account Auditing

In order to monitor significant security events like unauthorized access attempts, you need to enable auditing policies via:

Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Audit Policy

Ensure that both Success and Failure audits are enabled for all auditing options available.

Step 5: Clear Virtual Memory on Shutdown

Step 5: Erase Virtual Memory on Shutdown

To eliminate sensitive data being left in the page file on shutdown, set up the following policy:

Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options

Enable the Shutdown: Clear virtual memory pagefile policy. Be aware that this action might slightly delay your shutdown process.

Step 6: Manage Account Lockout Settings

Step 6: Configure Account Lockout Policies

Adjust the account lockout policy by navigating to:

Computer Configuration -> Windows Settings -> Security Settings -> Account Policies -> Account Lockout Policy

For enhanced security, consider the following settings:

  • Account lockout duration: 30 minutes

  • Reset account lockout counter after: 30 minutes

Pro Tip: Balance security and user experience by thoughtfully setting lockout policies.
