Data Compliance Understand the new Dynamic Access Control capabilities built into Windows Server 2012 Demonstration
Compliance is generally a response to governmental regulation, but it can also be a response to industry or internal requirements. The U.S. Health Insurance Portability and Accountability Act (HIPPA) for health providers Sarbanes-Oxley Act (SOX) The European Union Data Protection Directive U.S. state data breach laws I’m not talking about in-depth Datacompliance and privacy.
Can you make sure that only authorized individuals can access confidential data? Do you have granular control over auditing access? How to reduce the number of security groups your organization has? Deal with regulatory standard?…. There are many questions come up when it comes to data access control. Content Owner Infrastructure Information CSO/CIO Support Worker department ““Is my important data “I need to have appropriately “I don’t know “I don’t know if I the right protected and what data is in am complying compliance compliant with my repositories with my controls to keep regulations – and how to organization’s me out of jail” how do I audit control it” polices” this”

Data Classification File Classification Infrastructure provides insight into your dataData by automating classification processes.Classification File Classification Infrastructure uses classification rules to automatically scan files and classify them according to the Classify your documents contents of the file. using resource properties Some examples of classification rules include: stored in Active Directory. Classify any file that contains the string “SBC12 Confidential” as having high business impact. Automatically classify documents based on Classify any file that contains at least 10 social security document content. numbers as having personally identifiable information.

What is Central Access Policy? You can think of Central Access Policies as a safety net that your organization applies across its servers to enhance the local access policy
Expression-based access rules Active Directory File Domain Services server User claims Device claims Resource properties User.Department = Finance Device.Department = Finance Resource.Department = Finance User.Clearance = High Device.Managed = True Resource.Impact = High Access policy Applies to: @File.Impact = HighAllow | Read, Write | if (@User.Department == @File.Department) AND (@Device.Managed == True)

Data Encryption Challenges How do I protect sensitive information after it leaves my protected environment? I cannot get the users to encrypt their sensitive data.
Classification-based encryptionprocess Process to encrypt a file based on 1 classification Active Directory Claim definitions, file property definitions, and Domain Services access policies are established in Active Directory Domain Controller. A user creates a file with the word “confidential” in User the text and saves it. The classification engine 4 classifies the file as high-impact according to rules 2 configured. On the file server, a rule automatically applies RMS protection to any file classified as high- 3 impact. Classification RMS server engine The RMS template and encryption are applied to the file on the file server and the file is encrypted. File server

AD-Srv (Active Directory Domain Controller) File-Srv (File Server) There are two security groups Finance System Integration There are two domain users: email@example.com (Finance) firstname.lastname@example.org (System Integration)
