Business Impact on 2009 IT

External force are driving changes

© 2009 Crossbeam Systems 5

Diversity of uses accessing on-line business services

Dramatic growth in number of financially driven security threats from around the globe

Increase growth of bandwidth on the network

6

It’s all about Risk Mitigation

Affordable malware tools are spawning a sophisticated hacker business community

2008 saw more Malware than the past 20 years combined

Data is at Risk from all Vectors

Data is the most exposed attack surface

Can be reach by multiple attack vectors

“Defense in Depth” is no longer adequate

Vulnerabilities can exist in any area – look for the weakest link

Amount of Data is compounding the problem

Security Perimeters will continue to shrink and provide security between “Trust Boundaries”

Database Servers


Securing Trust Boundaries


Expensive to architect perimeters with different security levels

Expensive to manage rule / topology changes

Necessary.. BUT Complex

13

Applying Trust Boundaries was managed through physical separation of

servers

Level 1 (Web Servers)

Level 3 (PeopleSoft)

Level 2 (Oracle)

Level 4 (Database)


Was simple in the physical world

Architecture provided monitoring between Trust

Boundaries

How about Virtualization?

But that is not the biggest problem!

Virtualization Phase 2

2424

Top Server Virtualization Initiatives for 2009

Purchase third-party management software for virtual envi-ronments

Deploy a storage virtualization solution to support virtual server environment

Integrate virtual environments into existing management software frameworks

Implement virtual machine mobility / HA (high availability) func-tionality

Move more applications from test/development to production envi-ronment

Improve operational processes for managing virtual environments

Improve backup and recovery of virtual machines

Make use of virtual machine replication for disaster recovery

Expand number of applications running on virtual machines

Consolidate more physical servers onto virtualization platforms

Transitioning from Phase 1 2

Phase 1 – Basic Workload Reduction

Phase 2 – Enterprise Efficiency

Virtualization Unit Server Application

Primary skill set Server administration Server, application, database, networking, security, storage . . .

Networking Simple virtual to physical

More complex physical and virtual connectivity with L2 and L3 virtualization

L4-L7 services Single or multiple physical domains

Multiple virtual domains

Security Single or multiple physical domains

Multiple virtual domains


What are the problems to be solved in moving to phase 2?

Still need to manage security between Trust Boundaries with the Virtual Infrastructure

How do you add security protection between services running on the same hardware?

Should we load a Virtual Security Appliance (VA) on each server?

What happens when you have hundreds of servers…

What happens when a SysAdmin spins down or moves a Virtual Appliance accidentally or maliciously?


32

What is the process to manage multiple VAs between VMs between Trust Boundaries

Database Firewall

--- Trust Levels ---

33

How do we achieve the right level of visibility between trust boundaries when applications are virtualized?


34

Just ensure you have assigned the correct Ethernet port to the trunked VLAN and have enabled the right security services to

secure Trust Boundaries between the right Virtual machines and tap the right VM to monitor the traffic


Best Practices

3535

36

We need centralized “process-driven” control of security services between trust

boundaries


37

That’s as easy to change as sliding in a server


38

Can enforce Trust Boundary policies with any combination of security services


39

Can monitor any traffic between any trust boundaries with a click of a mouse


What’s Needed for Network Security?

Simple configuration management– Implementation, moves-adds-changes

Virtual security stacks– Defenses based upon asset value and risk– Customized protection– Any-to-any secure connectivity rules set

Integrated networking– Switching, routing, load balancing . . .

Graceful scalability– Support 100s of trust zones

End-to-end visibility– Common logging service– Security reporting and analytics

Implementation Possibilities

Map security zones– Understand all threat vectors and vulnerability to data– VLANs– Traffic– Services

Create security/networking profiles– Align with other IT skills

Assess management needs– RBAC (Roll-based access control), alerts, reports . . .
