Organizations have used AD to authenticate since 2001

2004Email is now business critical

Office 365 adoption is growing rapidly

• 22 million consumers (55% YOY growth from 12.4 M) and 70 million commercial customers who have active Office 365 subscriptions.

• In the commercial segment, Office 365 had a 57 percent month-over-month jump in the latest 2016 quarter.

• Year-over-year growth: about 1 million subscribers a month are adopting Office 365

Why do organizations move to the cloud?

• Reduce infrastructure, licensing, and maintenance costs, eliminating on-premises infrastructure and finding storage efficiencies

• Empower workforce to operate from anywhere from any device

• Increase scalability and business continuity

What about Azure Active Directory?

• Office 365 *requires* an Azure AD instance

• Azure AD provides the Directory Service for Office 365 applications

• Azure AD integrates with on-prem AD creating a HYBRID Directory environment

Azure Active Directory

Hybrid Environment: Azure AD Connect Synchronization Workflow

Summary: How Hybrid Directory was ‘created’

90% of Companies use AD-On prem.

O365 Adoption Growing at 70% YoY.

AAD has over 10M tenants

75% of Orgs. > 500 users synch AD-On

prem. >> AADHybrid Directory

How important is protecting on-prem AD resources?

75% of enterprises with more than 500 employees sync their on-prem AD accounts to Azure AD/Office 365 (AD on premises is authoritative)

If you’re leveraging Office 365, are you using Azure AD?

• Yes, managing Azure AD accounts• Yes, but only replicating to Azure AD from on-

prem• No, not using

Business Challenges

• Data exfiltration• Insider threats• Compliance failures• Prolonged operational downtime • Revenue loss due to downtime,

loss of productivity, and potentially fines

• No permission baselining• No automatic remediation• Lack of detailed auditing• Labor-intense/error-prone• Lack of granular delegation• Disjointed administration• Manual DR Processes

WHAT’S THE SOLUTION?Securing the weakest link in your hybrid directory

Quest AD Security Lifecycle Methodology

Continually Assess

• Who has access to what sensitive data and how did they get that access?

• Who has elevated privileged permissions in AD, servers, and SQL DBs?

• What systems are vulnerable to security threats?

Detect and Alert

• How will I know if any suspicious privileged account activities have occurred?

• Have any changes occurred that could be significant of an insider threat?

• How will I know, quickly, if an intrusion has happened?

• Could we be under brute-force attack right now?

Remediate and Mitigate

• Is access control allowing those whitelisted in and blacklisted out?

• Do my users have the lowest level of user rights possible to do their jobs?

• Are my sensitive resources protected?

• How much time will it take me to manually remediate unauthorized changes?

Investigate and Recover

• How can I be sure that ‘it’ doesn’t happen again?

• How can I test my business continuity plan without going off line?

• How long will it take us to recover from an AD security incident, manually?

• What is my AD RTO after a disaster?

• Can I secure access to my DC before next time?

Hybrid directory solution protects all the way around

Secure your Active Directory to mitigate risk in Office 365

• Organizations moving to Office 365 have real and significant security challenges around Active Directory.

• On-premises AD remains the core of security even in a cloud/hybrid environment.

• Quest offers the only end-to-end AD Security solution in the market

• Don’t let your on-premises AD be your Hybrid Achilles Heel!
