UNIT 5

Configuring, Managing and Troubleshooting Resource Access

Chapter 5 - Objectives

Set up security for folders and filesConfigure shared folders and shared folder securityInstall and set up the Distributed File System (DFS)Configure disk quotasImplement UNIX compatibility

UNIT 5

Managing Folder and File SecurityCreating accounts and groups are the initial steps for sharing resources

Next create access control lists (ACLs) to secure objects and set them up for sharing

Discretionary ACL (DACL)ACL configured by a server administrator or owner of an object

System control ACL (SACL)Information used to audit the access to an object

ACL – pronounced “ackel” like jackal or A. C. L. ACE – Access Control Element

UNIT 5

Configuring Folder and File Attributes

Attributes are stored as header information with each folder and file, along with volume label, designation as a subfolder, date of creation, and time of creation

Two basic attributes remain in NTFS that are still compatible with FAT - Read-only and hidden

The advanced attributes are: archive, index, compress, and encrypt

UNIT 5

Configuring Folder and File Attributes (cont)

Archive attribute - Indicates the folder or file needs to be backed up because it is new or changed

File server backup systems can be set to detect files with the archive attribute to ensure files are backed up

Index attribute vs. Windows Search ServiceThe NTFS index attribute is used to index the folder and file contents so files can be quickly searched in Windows Server 2008

through the Indexing ServiceWindows Server 2008 offers faster search service called: Windows Search Service – installed in the File Services role via Server Manager

UNIT 5

Windows Search Service

Intended to replace Indexing Service

UNIT 5

Configuring Folder and File Attributes (cont)Compress attribute - A folder and its contents can be stored on the disk in compressed format

Compression saves space, however, compressed files increase CPU overhead to open the files and to copy them

Encrypt attribute - Protects folders and files so that only the user who encrypts the folder or file is able to read it

An encrypted folder or file uses the Microsoft Encrypting File System (EFS)A unique, private encryption key associated with the user account that encrypted the folder or file

EFS uses both symmetric and asymmetric encryption techniques.When you move an encrypted file to another folder on the same computer, that file remains encrypted, even if you rename it

Encrypted files cannot be compressed!

UNIT 5

Attributes are stored as header information with each folder and file

UNIT 5

Configuring Folder and File PermissionsPermissions - Control access to an object, such as a folder or file

When you configure a folder so that a domain local group has access to only read the contents of that folder, you are configuring permissions

At the same time, you are configuring that folder’s discretionary access control list (DACL) of security descriptors

If you need to customize permissions, you have the option to set up special permissions for a particular group or user

UNIT 5

Folder PropertiesPermissions - Control access to an object, such as a folder or fileWhen you configure a folder so that a domain local group has access to only read the contents of that folder

You are configuring permissions

At the same time, you are configuring that folder’s discretionary access control list (DACL) of security descriptors

UNIT 5

UNIT 5

Special PermissionsTable 5-2 Unique situations for specific access

UNIT 5

Configuring Folder and File AuditingAuditing

Enables you to track activity on a folder or file

Windows Server 2008 NTFS folders and files Enable you to audit a combination of any or all of the activities listed as special permissions in Table 5-2

Configure auditing on a folder to monitor how it is accessed and who is making changes to the folder

UNIT 5

Configuring Folder and File OwnershipOnce permissions and auditing are set, you may want to verify the ownership of a folder.

-Folders are first owned by the account that creates them-Folder owners have the ability to change permissions for the folders they create

-Ownership can be transferred only by having the Take ownership special permission

Or Full control permission (which includes Take ownership)

UNIT 5

Configuring Shared Folders and Shared Folder Permissions

A folder can be set up as a shared folder for users to access over the network.

The first step for sharing a folder over the network is to turn on file sharing

UNIT 5

Configuring Shared Folders and Shared Folder Permissions

Share permissions - Differ from the NTFS access permissions set through the Security tab

The NTFS and share permissions are cumulative with the exception of permissions that are denied

Share permissions:ReaderContributorCo-ownerOwner

UNIT 5

Implementing a Distributed File SystemDistributed File System (DFS) - simplifies access to shared folders by setting up folders to appear as though they are accessed from only one placeIf DFS is used in a domain, then shared folder contents can be replicated to one or more DCs or member servers.DFS advantages: - Shared folders can be set up so that they appear in one hierarchy of folders enabling users to save time searching for information- NTFS access permissions fully apply to DFS on NTFS-formatted volumes- Fault tolerance is an option by replicating shared folders on multiple servers- Access to shared folders can be distributed across many servers (load balancing)- Access is improved to resources for Web-based Internet and intranet sites- Vital shared folders on multiple computers can be backed up from one set of master folders- DFS reduces the number of calls to server administrators asking where to find a particular resource- DFS in a domain enables folders to be replicated automatically or manually through Microsoft File Replication Service

UNIT 5

DFS ModelsStand-alone DFS model

No Active Directory implementation is available to help manage the shared foldersThis model provides only a single or flat level share

Domain-based DFS modelTakes full advantage of Active Directory and is available only to servers and workstations that are members of a domainEnables a deep, root-based, hierarchical arrangement of shared folders that is published in Active Directory

UNIT 5

DFS TopologyDFS topology - The hierarchical structure of DFS in the domain-based modelNamespace root - A main container (top-level folder) in Active Directory that holds links to shared folders that can be accessed from the rootNamespace server - The server that maintains the namespace root

After the namespace root is created, it is populated by shared folders for users to access. Folders are established in a level hierarchy and appear to be in one server location although they can be on many servers

Replication group - A set of shared folders that is replicated or copied to one or more servers in a domain

DFS is installed as a service within the File Services role

If the File Services role is already installed, but you don’t see the DFS Management tool on the Administrative Tools menu this means you didn’t install Distributed File System when you installed the File Services role

UNIT 5

DFS InstallationDFS is installed as a service within the File Services roleIf the File Services role is already installed, but you don’t see the DFS Management tool on the Administrative Tools menu, you didn’t install Distributed File System when you installed the File Services role

UNIT 5

Managing a Domain-Based Namespace Root System

Creating a folder in a namespace - A folder is simply a shared folder that you add to (or link to) the namespace rootFolder target - A path in the Universal Naming Convention (UNC) format, such as to a shared folder or to a different DFS pathUniversal Naming Convention (UNC) - A naming convention that designates network servers, computers, and shared resources

Clients who access the namespace can see a list of folder targets ordered in a hierarchy

Delegating ManagementDelegating management simply involves right-clicking the namespace and clicking Delegate Management Permissions

Tuning a NamespaceTuning options: Configure the order for referrals, Configure cache duration for a namespace, Configure cache duration for a folder, Configure namespace polling, Configure folder targets as enabled or disabled

UNIT 5

Configuring Disk Quotas

Disk quotas advantages:Preventing users from filling the disk capacityEncouraging users to help manage disk spaceTracking disk capacity needs on a per-user basis for future planningProviding server administrators with information about users quota limits

Disk quotas can be set on any local or shared volumeEstablish disk quotas by volume or userDisk quota management parameters:

Enable quota managementDeny disk space to users exceeding quota limit, Do not limit disk usageLimit disk space to, Set warning level toLog event when a user exceeds their quota limitLog event when the user exceeds their warning level

UNIT 5

Using UNIX Interoperability in Windows Server 2008

Subsystem for UNIX-based Applications (SUA)Provides interoperability between Windows Server 2008 and UNIX and Linux systems

SUA allows you to:Run UNIX/Linux applications with few or no changes to the program source codeRun UNIX/Linux scriptsUse popular UNIX/Linux shellsRun most UNIX/Linux commandsRun the popular vi UNIX/Linux editor
