Architecture Changes
• Exchange 2007 and 2010
•Five server roles primarily due to CPU
limitations
• Mailbox Server, Client Access Server
• Hub Transport Server, Edge Transport Server
• Unified Communications Server
•Had several restrictions
• Version Dependency
• Geo Affinity
• Session Affinity
Architecture Changes
• New Architecture in Exchange 2013
•Only Two Server Roles
• Mailbox Server Role
• Includes all the traditional server components: the Client Access
protocols, Transport service, Mailbox databases, and Unified
Messaging
• Handles all activity for the active mailboxes on that server
• Client Access Server Role
• Provides authentication, limited redirection, and proxy services
• Doesn’t perform any data rendering
• No data is cached or stored on the CAS
Architecture Changes
• Some Benefits of the New Design
• Version upgrade flexibility
• Session indifference
• Deployment simplicity
• CAS is no longer limited to same site access
• Three More Things
• RPC is no longer a supported direct access protocol
• Outlook clients no longer connect to FQDN but a new GUID
address learned from Auto Discover
• Exchange 2013 only supports Outlook 2007 and later
Policy and Compliance
• Data loss prevention (DLP) is a new feature in
Exchange 2013
• Helps protect your sensitive data by either using
built-in or custom policies
• Helps to keep your organization safe from users
mistakenly sending sensitive information to
unauthorized people
Policy and Compliance
• In-Place Hold
• In-Place eDiscovery
• Simultaneous searches across primary and archive
mailboxes
• Archive Lync content
• Retention Policy Improvements
• Calendar and Task Retention Tags
New Recipient Types
• In addition to the recipient types Exchange
2013 carries over from previous versions, a
few new ones have either been added or
modified:
•New Public Folders
•Site Mailboxes
•Shared Mailboxes
New Recipient Types
• New Public Folders
•No more public folder databases
•Public Folder hierarchy and content is now
stored in special mailboxes
•Public Folder replication is now handled by
continues replication model used by the
mailbox databases
• This also means Exchange is moving away from a
multi-master replication model towards a singlemaster replication model
New Recipient Types
• Site Mailboxes
•Email and documents are traditionally kept in
two unique and separate data repositories. This
usually results in a reduction in user
productivity and a degraded user experience
•Site Mailboxes try to rectify this problem by
providing a single interface to access mail
stored in Exchange and documents stored in
SharePoint
New Recipient Types
• Shared Mailboxes
•Shared Mailboxes are mailboxes that are
accessed by multiple users
•Did exist in Exchange 2010 but had to be
created in a separate multi step process
•In Exchange 2013, Shared Mailbox is a type of
recipient that can be created by a single step
from the EAC
Some Other Stuff
• New OWA interface designed for smartphones
tablets
• Batch mailbox moves
• Improved and simplified setup process
• Built-in
Anti-Malware Protection
• Includes Anti-Spam, Anti-Virus and Anti-Spyware
• High Availability Enhancements
• Automatic reseed
• Automatic recovery
and
Exchange 2013 RBAC Security
• What is RBAC
• What are the components of RBAC
• What are Scopes?
RBAC
Role Based Access Control
• The permissions to perform certain
tasks are granted to roles
• Users are assigned roles based on
their job functions.
• Permissions are based on the task,
rather than the resource.
RBAC is the permissions model used by Exchange 2013
Three ways to assign permissions
• Direct user role assignment
• Management Role Assignment
• Management Role Groups
Policies
Direct User Role Assignment
• Assigning
management roles directly to users or
groups without using a role group or a role
assignment policy.
• NOT RECOMMENDED!
Management Role Assignment Policies
• Collections of one or more end-user
management roles.
• Enable admins to specify how end-users
can manage
their own mailboxes and associated settings.
• All users are assigned a Default Role Assignment Policy
• Most organizations will choose to use the built in
Default Role Assignment Policy
Management Role Groups
• universal security groups used in RBAC permissions
model in Exchange 2010
• Simplifies the assignment of management roles to users
• Assigned administrator and specialist user roles
• Includes several built-in Role Groups, or uses custom
Role groups created by Exchange Admins
Adding or removing users and groups to Management Role Groups
is how you most often assign permissions to administrators or
specialist users
Role Holders
• Mailboxes that have been
added as members of a Role
Group
Management Role Group
• Universal Security Group that
contains Role Holders.
• Is assigned one or more
Management Roles.
• Is located in the “Microsoft
Exchange Security Groups” OU
in the forest root domain.
Role Group
Management Role
• Container for one or more
Management Role Entries
• Logical grouping of
cmdlets
• Used to define specific tasks
associated with a job duty
Role
Management Role Entries
• One or more cmdlets the role holder
will be allowed to run
• Role Entries can limit the parameters a
cmdlet is allowed to touch
• Role Entries can also reference scripts
the role holder is allowed to execute.
RBAC Scopes
• Scopes are used to control WHERE a role can be
exercised.
• Scopes are part of the Management Role
Assignment that binds a Role to a Role Group
Types of Scopes
• Scopes can be Implicit or Explicit
• Scopes can be Regular or Exclusive
• Custom scope types:
•OU Scope
•Recipient Filter Scope
•Configuration Scope
