Fix Recommendation

Regularly review local accounts and verify their necessity. Disable or delete any active accounts that have not been used in the last 35 days.

Check Contents

Run "PowerShell".
Copy the lines below to the PowerShell window and enter.

"([ADSI]('WinNT://{0}' -f $env:COMPUTERNAME)).Children | Where { $_.SchemaClassName -eq 'user' } | ForEach {
$user = ([ADSI]$_.Path)
$lastLogin = $user.Properties.LastLogin.Value
$enabled = ($user.Properties.UserFlags.Value -band 0x2) -ne 0x2
if ($lastLogin -eq $null) {
$lastLogin = 'Never'
}
Write-Host $user.Name $lastLogin $enabled
}"

This will return a list of local accounts with the account name, last logon, and if the account is enabled (True/False).
For example: User1 10/31/2015 5:49:56 AM True

Review the list to determine the finding validity for each account reported.

Exclude the following accounts:
Built-in administrator account (Disabled, SID ending in 500)
Built-in guest account (Disabled, SID ending in 501)
Built-in DefaultAccount (Disabled, SID ending in 503)
Local administrator account

If any enabled accounts have not been logged on to within the past 35 days, this is a finding.

Inactive accounts that have been reviewed and deemed to be required must be documented with the ISSO.
