Chapter 1: Executive Summary
EMC II, Pivotal, RSA, VCE, Virtustream, and VMware form a unique Federation of
strategically aligned businesses that are free to execute individually or together. The EMC
Federation businesses collaborate to research, develop, and validate superior, integrated
solutions and deliver a seamless experience to our collective customers. The Federation
provides customer solutions and choice for the software-defined enterprise and the
emerging third platform of mobile, cloud, big data, and social networking.
The Federation Enterprise Hybrid Cloud 3.5 solution is a completely virtualized data center,
fully automated by software. The solution starts with a foundation that delivers IT as a
service (ITaaS). Optional cloud services for database as a service, platform as a service, and
cloud brokering can be added to ITaaS to enhance the solution. There are also options to
implement high availability, data recovery, and backup and recovery services.
This solution guide provides information about the features and configuration options that
are available for securing system operations in an on-premises implementation of the
Federation Enterprise Hybrid Cloud 3.5 solution. It explains why, when, and how to use
these security features.
This solution guide is part of the Federation Enterprise Hybrid Cloud solution documentation
set and is intended for security architects, practitioners, and administrators responsible for
the overall configuration and operation of the solution. Readers should be familiar with the
®
VMware vRealize Suite, storage technologies, hybrid cloud infrastructure, and general IT
functions.
The following documents describe the architecture, components, features, and functionality
of the Federation Enterprise Hybrid Cloud 3.5 solution:
 Federation Enterprise Hybrid Cloud 3.5 Concepts and Architecture Guide
 Federation Enterprise Hybrid Cloud 3.5 Administration Guide
 Federation Enterprise Hybrid Cloud 3.5 Infrastructure and Operations Management
Guide
 Federation Enterprise Hybrid Cloud 3.5 Reference Architecture Guide
Table 2 in Chapter 10 lists publications that are related to understanding Federation
Enterprise Hybrid Cloud security. Chapter 10 also lists relevant documentation.
While many organizations have successfully introduced virtualization as a core technology
within their data center, end users and business units within the organizations have not
experienced many of the benefits of cloud computing such as increased agility, mobility, and
control. Many organizations are now under pressure to provide secure and compliant cloud
services to deliver these cloud computing benefits to their consumers. As a result, IT
departments need to create cost-effective alternatives to public cloud services, alternatives
that do not compromise enterprise security and features such as data protection, disaster
recovery, and guaranteed service levels.

Chapter 1: Executive Summary
Potential security threats must be addressed for organizations to maintain or improve their
security posture while enabling the business to continue to operate. In a cloud environment,
these threats must be addressed at both the underlying infrastructure and virtualized
workload levels. The cloud infrastructure can be protected with restricted administration-
level access, integration with authentication, logging, and monitoring systems, and system
hardening in case of attack. As virtualized applications are commonly available to end users
across the traditional enterprise perimeter, these applications and their consumers are
potential threat vectors.
Web application vulnerabilities, OS configuration errors, and missing patches are still
possibilities with virtualized workloads. However, cloud security technologies provide
controls to protect against these vulnerabilities; they also offer enhanced workload
containerization, which can limit the potential exposure of a successful attack and keep an
attacker from infiltrating other systems in the environment.
The Federation Enterprise Hybrid Cloud implements a variety of security features to control
user and network access, monitor system access and use, and support the transmission of
encrypted data. The security features related to the Federation Enterprise Hybrid Cloud are
®
implemented on the EMC and VMware systems and services that constitute the solution
and include the following:
 Public key infrastructure integration
 Converged authentication
 Centralized log management
 Security configuration management
 Secure multitenancy
 Data security
An increasingly interconnected world has created growth opportunities that are accelerating
with the rise of hybrid clouds. Organizations can now deploy information infrastructures
more quickly and run them with greater efficiency, control, and choice. These advances
foster business agility and connectivity, but they also create pervasive dependencies among
computing components that make problems and vulnerabilities difficult to contain. Complex,
interconnected electronic systems inevitably have software bugs and vulnerabilities. Even a
“perfect” product can develop problems through linkages to flawed partner products or to
subsequent changes in the technology environment that create new exposures.
The Federation meets these product security challenges by applying industry best practices,
as well as a flexible and standardized approach to prioritizing security throughout the
product lifecycle, from inception through sustainment. Trusted IT requires that products are
developed so that the risks of vulnerabilities are minimized, and flaws that surface are
assessed and resolved as quickly as possible. This end-to-end process is designed to protect
customers and to provide what customers need to enable protection.
The Federation believes that industry collaboration is invaluable for product security. Every
company has something to teach and much to learn. Industry collaboration on product
security has enabled Federation companies to help shape and quickly adopt best practices
that raise everyone’s level of trust in technology. The Federation is committed to
comprehensive product security programs that are built-in, transparent, and trustworthy.

Chapter 1: Executive Summary
The Federation Enterprise Hybrid Cloud solution integrates the best of EMC and VMware
products and services. It empowers IT organizations to accelerate implementation and
adoption of a hybrid cloud while still enabling customer choice for the compute and
networking infrastructures within the data center. The solution caters both to customers who
want to preserve their investment and make better use of their existing infrastructure and
to customers who want to build new infrastructures that are dedicated to a hybrid cloud.
The transition from either a physical or a partially virtualized infrastructure to a full hybrid
cloud enables a transformative approach to providing security. While many of the same
threats to physical environments still exist in the hybrid cloud model, there are new ways to
mitigate those threats by using the powerful capabilities of the Federation Enterprise Hybrid
Cloud. Network segments and boundaries become fluid because switches, routers, and load
balancers can be provisioned as needed to ensure that dynamically changing environments
remain secure, no longer dependent on hardware procurement or provisioning.
The traditional use of firewalls in North-South network traffic can easily be extended to
enforce restrictions on East-West traffic as well. This enables true micro-segmentation of
applications, application sub-tiers (web, middleware, and database), and application
environments (development, test/QA, and production). Newly provisioned virtual machines
can inherit security postures based on their role. Host-based security controls can run as
hypervisor kernel-level processes, allowing virtual machines to consume these services
without requiring additional software to be installed in every guest virtual machine.
This solution takes advantage of the strong integration between EMC technologies and the
VMware vRealize Suite. The solution, developed by EMC and VMware product and services
teams, includes EMC scalable storage arrays and data protection suites, integrated EMC and
VMware monitoring, and VMware software-defined networking and security to provide the
foundation for cloud services within customer environments.
