Encryption in Office 365

Office 365 Message Encryption is an easy-to-use service that lets email users send encrypted messages to people inside or outside their organization. Designated recipients can easily view their encrypted messages and return encrypted replies. Regardless of the destination email service—whether it’s Outlook.com, Yahoo, Gmail, or another service—email users can send confidential business communications with an added level of protection against unauthorized access.
There are many scenarios in which email message encryption might be required, including the following:
-A bank employee sending credit card statements to customers
-An insurance company representative providing policy details to customers
-A mortgage broker requesting financial information from a customer for a loan application
-A health care provider sending health care information to patients
-An attorney sending confidential information to a customer or another attorney
-A consultant sending a contract to a customer
About Office 365 Message Encryption

Office 365 Message Encryption is an online service that’s built on Microsoft Azure Rights Management (Azure RMS). With Azure RMS set up for an organization, administrators can enable message encryption by defining transport rules that determine the conditions for encryption. A rule can require the encryption of all messages addressed to a specific recipient, for example.
When a user sends an email message in Exchange Online that matches an encryption rule, the message is sent out with an HTML attachment. The recipient opens the HTML attachment in the email message, recognizes a familiar brand if that’s present, and follows the embedded instructions to view the encrypted message on the Office 365 Message Encryption portal. The recipient can choose to view the message by signing in with a Microsoft account or a work account associated with Office 365, or by using a one-time passcode. Both options help ensure that only the intended recipient can view the encrypted message.
The following diagram summarizes the passage of an email message through the encryption and decryption process.

DHCP Policy Based Assignment Windows Server 2012

How DHCP Policy Based Assignment Works-
DHCP policies are rules that you can define for DHCP clients. You can define a single policy, or several. Characteristics of DHCP policies include:

*Policy level: Polices can apply at the server level or the scope level. Server level policies are processed for all DHCP client requests received by the server. Scope level policies are processed only for DHCP client requests that apply to a specific scope.

*Processing order: Each policy has an associated processing order that is unique within a server or scope. Policies with a lower numbered processing order are evaluated before higher number policies. If both scope and server level policies apply to a client, the scope level policies are always processed before any server level policies.

*Conditions: The conditions specified in a policy enable you to evaluate clients based on fields that are present in the DHCP client request. If a client request matches the conditions in the policy, the settings associated with a policy will be applied to the client by the DHCP server when it responds to the DHCP request.

*Settings: Settings are network configuration parameters (ex: IP address, options, lease duration) that are provided to DHCP clients in the DHCP server response. Settings enable you to group clients by applying the same set of network parameters to them.

*Enabled/Disabled: Policies at the scope or server level can also be enabled or disabled. A policy that is disabled is skipped when processing incoming DHCP client requests.
