Virtualization Security

PowerVM hypervisor has never had a reported security vulnerability and provides the bullet-proof security that customers demand for mission-critical workloads

Dare to compare – search any security tracking DB and compare Power against x86

IBM

0 reported security breeches

on the PowerVM hypervisor


Unlike x86-based virtualization products, the PowerVM hypervisor is secure by design. IBM is the only vendor that has designed the virtualized

environment from ‘bare metal’ through the hypervisor.

PowerVM hypervisor is part of the digitally-signed firmware with strong

cryptography which makes it very difficult to attack.

There are zero vulnerabilities reported against the PowerVM hypervisor by

US CERT or by MITRE Corporation

PowerVM is certified at a Common Criteria Evaluated Assurance Level 4+

Remember, zero is a number too …a very good number in the Security domain.

PowerVM delivers firmware-based security


SAP on Power versus competitive SAP deployments study with over 54,150 clients analyzed

The security for ERP systems, including SAP, can be very challenging – by nature, the mixture of application modules, user profiles, plug-in components and so on, provide many avenues for security breaches

Common Security Vulnerabilities: AIX versus Linux


Scalability beyond x86�Optimization well beyond 4 sockets – up to 256 cores

�Elastic capacity on demand to provide flexible change in capacity

Highly efficient virtualization based on mainframe technology�Allows flexibility to automatically respond to workload changes�Improved IT agility to support new business initiatives

Built-in security�Firmware based hypervisor

�Proprietary operating system features

Availability – avoiding unplanned and planned outages�Mainframe inspired hardware resilience and reliability design

�AIX features designed to isolate and avoid outages

Summary: Why Power versus X86


PowerSC provides a security and compliance solution to protect datacenters virtualized with PowerVM enabling higher quality services

Capabilities

Trusted Logging The SVM/VIOS capture all LPAR audit

log information in real time.

Trusted BootBoot images and OS are

cryptographically signed and validated using a virtual Trusted Platform Module

(vTPM)

Trusted Firewall Provide integrated firewall inside of

the virtual network infrastructure

Security Compliance Automation (PowerSC Express)

Pre-built compliance profiles that match various industry standards such as

Payment Card Industry, HIPAA, DOD and Sox/Cobit. Activated and Reported on

centrally using AIX Profile Mgr

update level.

Ensure that every Virtual System has appropriate

security patches

PowerSC Standard Edition


Challenge: Prevent malicious users from “covering their tracks.”

Power SC Solution: Move log events to a secure external VM via the hypervisor. Centralized logging ensures that even when virtual machines are discarded the audit logs remain on the central location for audit purposes.

• Discourage malicious activity by ensuring individual accountability; trace actions to authenticated individuals.

• Reduce the time it takes to identify tampering and/or unauthorized changes

• Reduce the time it takes to demonstrate Security Compliance by maintaining strict control over audit logs.

How PowerSC works: •Trusted Logging provides tamperproof secure centralized protection for AIX audit and system logs and is integrated with PowerVM virtualization. •Limited access to the Secure VM to a few privileged super users•Guest VM logs can be managed and backed up from a single location within each physical server. •Log scraping agents and reporting agents can be removed from guest OS.

PowerSC – Trusted Logging


Challenge: Ensure that every virtual machine image in your datacenter hasn’t be altered either by accident or maliciously.

PowerSC Solution: Trusted Boot forms the core root of trust for the image, i.e. a foundation for trust. Each stage of the boot process measures the next, starting at the firmware.

• PowerSC offers the only solution on the market to form a chain of trust for VMs all the way from boot to application!

• Improve QoS by reducing the risk of accidental or malicious image tampering

• Reduce the time it takes to ensure that every VM in your datacenter is running authorized and trusted software.

How PowerSC works:1.Measure the boot process and securely store the results in a Virtual Trusted Platform Module(vTPM)2.Provide a sealed set of measurements to the requestor3.Verify these measurements against a reference manifest

Applications

O/S

Kernel

BIOS

PowerSC – Trusted Boot and Trusted Execution


Challenge: Ensure that images are trusted and at the proper patch level when they connect to the network.

PowerSC Solution: Trusted Network Connect and Patch Management detects noncompliant virtual machines during activation and alerts administrators immediately.

• Reduce business risk by active notification of down level systems via email and SMS.

• Lower admin costs by automatically spotting non compliant systems within the virtual data center and cloud environments

• Lower costs of demonstrating compliance. Monitoring at virtual machine activation proves compliance to patch policy

Out of

compliance

How PowerSC works: • An image that does not meet trusted measurements and patch levels will trigger an alert to the administrator.

PowerSC – Trusted Network Connect


Challenge: Ensure that every virtual machine has appropriate network isolation with the best possible performance.

PowerSC Solution: Trusted Firewall provides network isolation for VMs and layer 2,3,4 firewalling between virtual workloads within the server.

• Improves performance by providing network firewall services within the server not requiring an external firewall for VM to VM traffic on the same CEC.

• Reduces network resource consumption by not using network resources for VM to VM network traffic when VMs are running on the same CEC.

How PowerSC works:1.When network traffic flows from one VM to another on the same CEC, the Trusted Firewall which is running in the VIO server provides network isolation and firewall services between VMs.2. Trusted Firewall is managed just like any firewall with either Tivoli Netcool or BladecenterHarmony Manager or via the command line.

PowerSC – Trusted Firewall


Challenge: Demonstrate compliance to Regulatory standards by setting security configurations on systems in a uniform manner.

PowerSC solution: Compare settings across all of the systems in the datacenter against prebuilt profiles, e.g. Payment Card Industry (PCI), HIPAA, DoD STIG and COBIT.

• Lower Administration costs by setting security configs in a repeatable manner

• Lower Admin costs by automating compliance reporting

• Automatic remediation of servers that are out of compliance

How PowerSC works: • A single dashboard monitors compliance and generates audit reports.• Sets and checks compliance for systems based on prebuilt security profiles

PowerSC – Security Compliance Automation


AIX Workload Partitions (“WPARs”)

What is it?

�Virtualized AIX operating system environments within a single AIX image

�Each WPAR shares the single AIX operating system but can be separately managed

�Applications and users inside a WPAR cannot affect resources outside the WPAR

�Each WPAR can have a regulated share of processor, memory and other resources

�Two types of WPAR:�System WPARs have separate

security and appear like a completely

separate OS

�Application WPARs are manageability

Active Memory Expansion compresses in-memory data to fit more data into memory

� Increases the effective amount of memory capacity

Initial version of active memory expansion is managed by the OS and hypervisor

� OS compresses and decompress data based on memory accesses

Memory compression is transparent to applications

Active Memory Expansion requires additional CPU utilization for compression

� CPU utilization will vary based on workload

Active Memory Expansion is configurable on a per-LPAR basis

� Supports dedicated memory LPAR’s and active memory sharing LPAR’s

Expand memory capacity through in-memory data compression

Active Memory Expansion – POWER7+ & AIX


POWER7+ uses on-chip hardware accelerator to do some of the compression / decompression work. There is a knee-of-cure relationship for CPU resource required for memory expansion

� Even with POWER7+ hardware accelerator there is some resource required.

� The more memory expansion done, the more CPU resource required

Knee varies depending on how compressible memory contents are
