4 IG considerations in context of O365

Executive Sponsor • IG is primary stakeholder for O365 planning, strategy, and management Information policy development and communications • Policies created to account for and/or adapt to O365 Information organization and classification • Labels and auto-classification and what to use when Information security • Identifying and protecting sensitive content with data loss prevention and information rights management Information accessibility • Right people at the right time via Teams, Groups, SharePoint Information control • Identify, classify, access, preserve, review, records management, eDiscovery Information governance monitoring and auditing • Data loss prevention, Supervision, Data Governance dashboards

5 Keep in mind

– Pros and cons of O365 adoption from your perspective – What features and functions to adopt? – Technology replacement opportunities?

– SourceOne – DMS – DLP – Others

6 O365: monumental impact on information governance and eDiscovery

The widespread adoption of O365 is one of the most disruptive and significant trends to hit the Information Governance and eDiscovery professions in the past 20 years

7 Why? Reason #1: Office 365 is an evidence factory and warehouse

• Factory for creating ESI: – Email – Files: Word, Excel, PowerPoint, OneNote – Web – Chats: Instant Messages

• Warehouse for storing ESI: – Mailboxes – SharePoint document libraries – OneDrive for Business – Teams – – Groups

9 Reason #2: Office 365 is becoming the leading enterprise and business email system worldwide

• Email is involved in MOST cases and frequently is KEY evidence • Whatever system houses email naturally is a focal point for discovery • The email system impacts—in part or in whole:

– Where email is stored – How email is stored – How long email is retained – Whether email is purged on a regular basis – How easy or difficult it is to identify, preserve, and collect

10 10 Reason #3: Office 365 is a powerful reflection and amplification of general IT trends

• Cloud computing: Office 365 is THE quintessential cloud computing platform

– Massively scalable “utility” computing – IT infrastructure owned and managed by provider (DR, backup, etc. under exclusive control of )

• “Apps” with rapid development and deployment

• Social media infused user experience

– Facebook, Snapchat, Instagram – Communicating using acronyms, emoticons, graphics, pictures, video, giphy

11 11 Reason #4: built-in eDiscovery and Information Governance tools

• eDiscovery tools: – Identification – Preservation – Collection – Processing – Analysis

• Information Governance tools: – Retention and disposition – Compliance – Information Security

12 Background

13 Some history

14 Adoption of O365 is fast and furious

• 35% growth in commercial seats

• 50k small businesses adopt Office 365 every month

• 80% of Fortune 1000 have Office 365

• Office 365 is Microsoft’s fastest growing commercial product ever

• Office 365 eclipsed Salesforce.com as the most widely used cloud-based business application

• 100 million active commercial Office 365 users

15 Why do organizations move to Office 365?

• Cost and financial implications

– Fixed predictable pricing /$ per user per month – Operational vs. capital expense • Reduced burden on IT: easier to deploy and manage than on-prem

– Less infrastructure to integrate and manage – Basic patching, updates, server replacements handled by Microsoft – New features and functions rolled out automatically • Tools! Apps! Something for everyone to be more collaborative and productive

– Groups, Teams, Planner, StaffHub • Built to be deployed on multiple devices and available 24/7

– Mobile and cloud first! Microsoft’s mantra 16 Dynamics introduced by the move to O365

17 Dynamics introduced by moving to Office 365

• New content types

– Conversations and Chat-based communications with emoji, emoticons, Memes, Giphy, etc. – Planner – Sway • New storage locations

– OneDrive for Business – Office 365 Groups – Teams – Yammer • Change

– Persistent, continuous, and at high velocity • Lower bar to deployment

– Heavy IT integration and configuration is handled by Microsoft – Easier to deploy and consume features such as Instant Messaging, collaboration, Information Rights Management, etc. 18 Dynamics introduced by moving to Office 365: what ESI to move?

“Information Governance” “Information Forklift move? cleanup prior to move? Everything Governance” cleanup – Identify Redundant Obsolete and Trivial (“ROT”) data after move? • Not subject to legal hold – Move ESI into O365 then turn on • Not subject to legal, regulatory, or business retention policies • Develop criteria (age, author, duplicate, etc.) – Identify data subject to legal hold – Identify data subject to legal, regulatory, or business retention requirements (records, work in progress, etc.) – Document actions taken • Approval for disposition • What was disposed, when, by whom

19 19 Dynamics introduced by moving to Office 365: adoption

• Email is typically 100% adoption Server

– PSTs PST – Archive Archive

• OneDrive for Business adoption:

PC – Will we adopt? Documents – Will it become our corporate standard for user file Home OneDrive sharing? Share File Sharing – Will we migrate home share, My Documents? Service

Department • File shares to SharePoint Online document libraries Shares Public adoption Shares

– Will we adopt? Project Shares – Will SPO replace file server based file sharing? 20 – Will me migrate file shares to SPO? 20 Dynamics introduced by moving to Office 365: adoption

• Groups • Teams • Planner • Yammer • StaffHub • PowerBI

–*Adoption of these tools have IG implications

21 21 What is Office 365? What is Office 365?

• Suite of Services/Products – E-mail, Instant Messaging, Collaboration, File Sharing – Office (Word, Excel, PowerPoint, Access, etc.), Exchange, SharePoint,

• Cloud

– Quintessential example of cloud computing Cloud – Hardware, storage, backup and disaster recovery are handled by Microsoft

• Software as a Service (SaaS) – Individuals, companies, organizations subscribe to the service for a fixed monthly or annual fee

59 In a nutshell: eDiscovery Features in Office 365

“Standard” eDiscovery (E3)

1. Search across one or more mailboxes, OneDrive for Business, SharePoint sites, O365 Groups, Teams – Keywords, proximity, date range, metadata

2. Preserve In-Place (hold) – No disruption to custodians—they don’t know they are on hold – No collect or copy to preserve – No journaling

3. “Preview” preserved content – Not a review tool!

4. Collect and export – Mailbox ESI  PST or MSG – ODB and SharePoint ESI  Native

63 What DOESN’T Office 365 eDiscovery do “out-of-the-box?”

• Legal hold notification and workflow

– Telling custodians they are on hold and tracking acknowledgements – Sending out questionnaires – Providing audit trail of when and who is on legal hold

• Does not identify, preserve, or collect ESI located outside of Office 365-for example:

– Desktop, laptop, tablet computers – File (network) shares – Smartphones

• “Full” eDiscovery processing

• Review

• Production

64 Enabling defensible legal hold: Recoverable Items Folder

• Users do not have access to the recoverable items folder

• eDiscovery search and hold does have access

• Has its own quota of 100 gig (if legal hold enabled)

• Can view via MFCMAPI client

• Deletions

• Contains all items deleted from the Deleted Items folder. • This folder is “seen” by end users via “Recover Deleted Items” • Versions

• If hold in effect, contains original and modified copies of the deleted items • Purges

• If hold OR SIR in effect contains all items that are “purged” (“dumpster” deleted/triple deleted) • Audits

• If mailbox logging is enabled, contains mailbox audit entries • DiscoveryHolds

• If “scoped” hold in effect this is where purged items go • Calendar Logging

• Contains calendar changes that occur within a mailbox

65 Enabling Defensible Legal Hold: Preservation Hold Library

• A “preservation hold library” is created the first time a SharePoint site is put under hold. • Users can continue to work on content without disruption • Content on hold-including web pages, documents, lists, and other items are preserved as needed (if user edits an item it prompts preservation) • Users don’t see the preservation hold library • To preserve all versions of content in a site versioning must be enabled

66 eDiscovery permissions

– eDiscovery Administrator

– Can see all cases – Can create new cases Assign to – Can assign cases to self or eDiscovery outside managers counsel and – eDiscovery Manager service provider – Can see own cases or those assigned to *Does not him/her require a – Can create new cases license – Can assign other eDiscovery Manager to their cases – Permissions filtering

– Restrict the mailboxes and sites an eDiscovery Manager can access – May use recipient fields to limit (country, department, title, custom, etc.) https://support.office.com/en-us/article/Assign-eDiscovery-permissions-in-the-Office-365-Security-Compliance- Center-5b9a067b-9d2e-4aa5-bb33-99d8c0d0b5d7?ui=en-US&rs=en-US&ad=US 67 Permissions Filtering (Scoping eDiscovery Manager Access)

• eDiscovery Administrators and Managers by default can search all mailboxes, SharePoint sites, Groups, Teams, etc. • Restrict eDiscovery Manager to searching:

– Subset of mailboxes AND sites – Content that meets specific search criteria (i.e., must contain word “Microsoft”) • Recipient filter

– City, Company, Country Code, Custom Attribute, etc. (https://technet.microsoft.com/library/bb738157(EXCHG.150).aspx) • Searchable message property filter • Managed via PowerShell (requires Organization Management membership) • Requires connecting to BOTH Exchange Online and SCC • Applies to inactive mailboxes • Does NOT apply to Exchange Public Folders

68 eDiscovery Permissions

Compliance eDiscovery Manager Organization Role Reviewer Administrator & Administrator Management Case Management Lets users create, edit, delete, and control access to eDiscovery cases in the Security & Compliance Center. For more information, see Manage eDiscovery cases in the Office 365 Security & Compliance Center. As previously explained, a user must be assigned the Case Management role before you can use the Add-eDiscoveryCaseAdmin cmdlet to make them an X X X eDiscovery Administrator. Compliance Search Lets users run the Content Search tool in the Security & Compliance Center to search mailboxes and public folders, SharePoint Online sites, OneDrive for Business sites, Skype for Business conversations, Office 365 Groups, and Microsoft Teams. This role allows a user to get an estimate of the search results, but additional roles are needed to perform actions such as previewing, exporting, or deleting search results. X X X For more information about Content Search, see Run a Content Search in the Office 365 Security & Compliance Center. Export Lets users export the results of a Content Search to a local computer. It also lets them prepare search results for analysis in Advanced eDiscovery. For more information about exporting search results, see Export search results from the Office 365 Security & Compliance Center. X Hold Lets users place content in mailboxes, public folders, sites, Skype for Business conversations, and Office 365 groups on hold. When content is on hold, content owners will still be able to modify or delete the original content, but the content will be preserved until the hold is removed or until the hold duration expires. For more information about holds, see: X X X Manage eDiscovery cases in the Office 365 Security & Compliance Center Overview of retention policies Preview Lets users view a list of items that were returned from a Content Search. They’ll also be able to open and view each item from the list to view its contents. X Review Let's users see and open the list of the cases on the eDiscovery page in the Security & Compliance Center that they are members of. They can't perform any other case management tasks. X X RMS Decrypt Let's users decrypt RMS-encrypted email messages when exporting search results or preparing search results for analysis in Advanced eDiscovery. For more information about decrypting search results during export, see Export search results from the Office 365 Security & Compliance Center.

• InternetMessageId This property specifies the Internet message identifier of an email message, which is a globally unique identifier that refers to a specific version of a specific message. This ID is generated by the sender's email client program or host email system that sends the message. If a person sends a message to more than one recipient, the Internet message ID will be the same for each instance of the same message. Subsequent revisions to the original message will receive a different message identifier.

• ConversationTopic This property specifies the subject of the conversation thread of a message. The value of the ConversationTopic property is the string that describes the overall topic of the conversation. A conservation consists of an initial message and all messages sent in reply to the initial message. Messages within the same conversation have the same value for the ConversationTopic property. The value of this property is typically the Subject line from the initial message that spawned the conversation.

• BodyTagInfo This is an internal Exchange store property. The value of this property is calculated by checking various attributes in the body of the message. This property is used to identify differences in the body of messages. • If values for two or more of above are the same the message is deemed duplicate • ****Messages a user edits but doesn’t send are identified erroneously as duplicates
