Vulnerability discussion

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities.The "Deny log on through Remote Desktop Services" right defines the accounts that are prevented from logging on using Remote Desktop Services.If Remote Desktop Services is not used by the organization, the Everyone group must be assigned this right to prevent all access.In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower trust systems helps mitigate the risk of privilege escalation from credential theft attacks which could lead to the compromise of an entire domain.Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks.The Guests group must be assigned this right to prevent unauthenticated access.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
