  Step 1:  Defining Local Security

Open a Report
Windows NT uses local and network security to access resources. Network security is handled with share permissions as defined in the previous tutorial. Local security is local to the machine where the resource resides. If Bob and Sally use the same computer, local security can be configured so that Bob cannot see Sally's local folders and vice-versa through NTFS. NTFS has stricter access controls than share permissions.
  Step 2:  Attributes of NTFS

Open a Report
NTFS is unique to Windows NT and Windows 2000. Other operating systems cannot see the file systems. This only effects you if you're booting Windows NT and another operating system on the same computer. It does not effect the ability to access network resources. NTFS has virtually no limit on partition sizes. NTFS can be compressed. NTFS can set security down to individuals files within the same folder.
  Step 3:  Setting NTFS Folder Permission

Open a Report
To set NTFS permissions, Right-click My Computer and choose Explore. Locate the folder on the NTFS partition you'd like to restrict access to. Right-click the folder and chose Properties. Click the Security tab, and then click Permissions. From here you can remove any account, edit the right to a resource, or click add to allow more users or groups to access the resource.
  Step 4:  Editing Existing Security

Open a Report
To edit any existing security on a folder, right-click the folder and choose Properties. On the security tab, click Permissions and then add, remove, or edit the level of access to a resource.
