Agenda• What is SP 800-125• Why virtualization• Full virtualization• Security concerns• Recommendations for Security for full virtualization technologies• Summary• Questions and answers• Resources
SP 800-125• Full Virtualization technologies• Server and desktop virtualization• Security threats• Security recommendations for protecting full virtualization
Forms of Virtualization• Simulated environment• Not cover OS and application virtualization• Full virtualization – CPU, storage, network, display, etc• Hypervisor and host OS• Virtual Machine (VM) – Guest OS – Isolated – Encapsulated – Portable
Full Virtualization• Bare metal virtualization• Hosted virtualization• Server virtualization• Desktop virtualization
Virtualization and Security Concerns• Additional layers of technology• Many systems on a physical system• Sharing pool of resources• Lack of visibility• Dynamic environment• May increase the attack surface
Recommendations for Security for Full Virtualization Technologies• Risk based approach• Secure all elements of a full virtualization solution and perform continuous monitoring• Restrict and protect administrator access to the virtualization solution• Ensure that the hypervisor is properly secured• Carefully plan the security for a full virtualization solution before installing, configuring, and deploying it
Summary of Threats and Countermeasures• Intra-guest vulnerabilities – Hypervisor partitioning• Lack of visibility in the guest OS – Hypervisor instrumentation and monitoring• Hypervisor management – Protect management interface, patch management, secure configuration• Virtual workload security – Management of the guest OS, applications, data protection, patch management, secure configuration, etc• Virtualized infrastructure exposure – Manage access control to the hardware, hypervisors, network, storage, etc.

Virtualization Security vs Compliance Compliance: the state of being in accordance with established guidelines, specifications or legislation or the process of becoming so. Compliance Security (?) (NIST 800-125)Do you know?• Whether your organization has security guidelines defined for its virtual environment?• Which regulations your organization is subject to?• Whether your virtualization efforts will be subject to regulatory scrutiny?• Whether your security baselines for your virtual environment incorporate your regulatory obligations?

Questions You Should Be Asking Today Do you allow shared privileged access to your sensitive servers? How do you account for privileged user’s actions? Can your system administrators access sensitive data on the servers? Do you have controls to prevent/log that? Can you trace administrative action back to administrative users? Have you had system down incidents where you needed to do so? Do you have any controls in place to prevent shared account access on your sensitive servers? What server operating systems do you have deployed? How do you manage security across them? How do you provide evidence of compliance?28 28
