Create a Contingency Plan

Step 6: Prepare to recover by creating a contingency plan.

Finally, organizations have to adjust to the continuous state of potential data breach and insider threats by assuming a breach will take place and preparing themselves to recover. This means a contingency plan must cover various areas, including daily backup of AD database information, tight control over the rights to back up and restore AD objects, encryption of AD backups on disk and establishment of a recovery time objective (RTO) for a full AD recovery.

Adoption of cloud services has undeniably soared, with Microsoft calling Office 365 its fastest growing commercial product ever, and more than 70 percent of Fortune 500 companies now using at least two different Microsoft cloud services. However, while organizations are actively deploying more cloud applications, they are also keeping on-premises solutions, creating a hybrid environment of both on-premises and cloud-based applications.

To manage employee authentication, identity management and access control policies across hybrid environments, companies often leverage the Azure Active Directory (AD) Connect management tool, which performs a one-way sync from on-premises AD to the online Azure AD. The problem is that on-premises AD does not include the same types of security controls that the cloud-based version does, leaving a big hole in an organization's security program that exposes the business to risk.

In this slideshow, Alvaro Vitta, principal solutions consultant specializing in security at Dell Systems and Information Management, recommends six steps for organizations to strengthen their hybrid directory environment to ensure successful hybrid cloud environment performance.
