PROCEDURES

1. Sending Secure, Encrypted Email from Outlook has been made very easy for NYSERDA users now on the Office 365 email platform. To send an encrypted email to an external user you simply need to add the appropriate wording to the Subject of the message.
   1. Create new message in Microsoft Outlook and add the recipients like usual.
   2. Enter the following to the beginning of your "Subject" #encrypt

Then enter the rest of the subject as you would like it to be seen

        2. Information may be intercepted in motion when sending an email to an external stakeholder so attachments must be converted to an Adobe or MS Word or Excel .xlsx password protected file for data with a classification rating of moderate or high for confidentiality before sending an encrypted email to an external stakeholder or emailing a State entity within the ITS domain.

For encrypted email, the content of the email is the only information that is encrypted. The password protected file ensures the information stays secure. Reference instructions on sending an encrypted email. The receiver of the email must have a Microsoft Account or be given a one-time password to access the information.

   The password should be provided over the phone or in a separate email. With so many email accounts compromised at other entities, it is recommended to transmit the password over the phone if possible.
   The password must be changed every 90 days and contain 8 characters of upper/lower case, number, and special characters.
  

       3. Once you are done creating your message and adding password protected attachments. Click SEND. Be sure you have #encrypt in your subject as that is key! NOTE: You can also do this same process from the Outlook Web Client at {+}https://outlook.office365.com/owa+ when logged in with your nyserda.ny.gov or greenbank.ny.gov user id!

      4. Send a separate, normal (non-encrypted email) to the recipient(s) alerting them that they will be receiving an encrypted email. Below is an example email message:

                      Dear [name],

                       NYSERDA uses encryption by Microsoft Office 365 to securely email Personal, Private, and Sensitive Information (PPSI).  

                       You will be receiving an encrypted email from me  The email Subject will begin with  #encrypt.   Below is a sample encrypted email along with instructions on how to view the message using your Microsoft Account or One Time Passcode.                        The saved attachment will open in your default Web Browser and instructs you to login with your Microsoft Account or select Use a One-Time Passcode to view the message.

                           If you select the One-Time Passcode option, you will instantly receive an email with the code. Enter the code into the web page as instructed

                           Please contact me if you have any questions or issues accessing the encrypted email.  We appreciate your commitment to protecting sensitive information.

DATA LOSS PROTECTION (DLP)

Data Loss Protection (DLP) to prevent unprotected sensitive information in outgoing email.  NYSERDA’s Data Governance Council have agreed to enforce the least disruptive action known as the DLP encryption template.  This encryption template is effective immediately.

The DLP encryption template effects emails and attachments that contain:

• Social Security Number
• US Taxpayer ID
• Passport Number
• Credit Card Number
• Bank Account Number (personal and business)

Since NYSERDA users the centralized Office 365 system, our emails are already encrypted therefore this automatic encryption will not affect the following communication:

• Emails to @nyserda.ny.gov
• Emails to other NYS entities that are O365 tenants at ITS.  Note that being listed in the global address list (GAL) does not guarantee a state entity is participating in the ITS O365 tenant.

Receiving the email works the same as utilizing #encrypt referenced above.
