Shares and NTFS Permissions, Offline Files, VSS, Work Folders

Share Permissions
Network Only
1st line of defense
Read, Change, Full Control
Folders only
Effective permission with multiple group membership
Deny always wins
Combine with NTFS
Administrative shares
Configuring Access-based enumeration which displays only the files & folders that a user has permissions to access.If a user does not have Read(or equivalent)permission to a folder,windows hides the folder from the user's view.


NTFS Permissions
Primary tool for access control
Files and folders
Applies locally + Remotely
Inheritance applies
 -can block parent
 -can reapply parent
Standard Permission:Full contorl,modify,R+W,R,W,list
Advanced permissions

Order of inheritance (bottom to top)
1.Explicit Deny
2.Explicit allow
3.Inherited deny
4.Inherited allow

Effective access in Advanced security settings - provide what if scenario

Offline Files
Network Shares (offline settings)
Files available when disconnected or "Work Offline"
Very good sync mechanism
Configure with "Offline settings"(caching) or GPO (Computer Cfg-Admin Templates-Network-Offline files)

Disk Quotas
Limit Disk usage
configuration
 -windows explorer
 -templates
 -soft or hard
 -drive only in explorer
 -set quota for folders in File server resource manager(FSRM) -very useful for file servers
Data Deduplication

Volume Shadow Copy
VSS Useful for
 -VM Snapshots
 -Backup operations(VSSAdmin alone is not Backup)
 -File recovery
File Recovery
 -On the fly restore
 -Schedule shadow copies
 -Not limited to shares
 -Monitor large restore jobs
VSSAdmin query reverts /For=Volume, /All
To configure, right click on the drive->configure shadow copies->Enable

Work Folders
Access to User's own work files
 -SMB/Mapped
 -Domai joined worktation
 -Non-domain joined workstation, bring your own devices(these are advantages over offline files)
Available when connected or not
Offline changes automatically synced when reconnected
Transparent conflict resolution(files will be named <name+pc name>if there is conflict)
Hub/Spoke topology
Works with file screens, classification, quotas, clustering
Grant access in setup (best with Group + fine tune with NTFS permission)
Security policies for encryption, screen lock
Can implement with existing folder redirection,offline files,home
Must be locally attached server storage
 -No DFS
 -No VNC source
1 work folder per user per device
Not collaborative (look to sharepoint, skydrive pro)

Server Basic Configuration Steps
 -Define appropriate users-->Groups
 -Add Sync server role (under Files and Storage Services)
 -Configure Role
 -DNS (create A record), Certs, Proxy

Client Configuration
 -Control panel configuration
 -Access via "work folders"
 -Can enforce with GPO (computer cfg-administrative templates-windows componenets-work folders). (user cfg-administrative templates-windows componenets-work folders)
