 Required agent based firewalls, filters and protection
 Day Zero attacks not always addressed
 Reaction only as fast as update distribution
 Not cost effective to make the entire network a firewall
 Traditional Desktop admins not firewall savvy

Physical Security Challenges

Challenges with Firewalling Typical Desktops
 Distributed and mobile model make protection of physical
desktops very problematic
• Very Rare to See Real Segmentation of Desktops
• Requires Complicated physical or VLAN based rule sets are necessary for network
based firewalling
• Laptops or other mobile devices may connect into different network segments
• Port based rules and policies very difficult to manage
• Endpoint based firewalls are very difficult to manage and don’t scale
• Requires individual rule sets for every desktop
• As new desktops come online, they must be configured with specific rule sets
• What happens when a user connects remotely
• Access rights must be set for each user or type of user logging in
• This is in addition to endpoint based rules
 What can we learn by what we do with the datacenter and how we
firewall and protect the datacenter?

vShield App
Better, faster protection
• vNIC level protection – eliminates VLAN blind spots, firewall chokepoints and L2 attacks
• High performance distributed enforcement – lowers firewall and VLAN capital investment costs
Simpler, easer to operate
• Dramatically reduced number of VLANs – removes VLAN complexity
• Container & Security Group based policies are “change aware” and easy to understand
• Dramatically smaller number of rules reduces chance for policy configuration errors
• VC integrated and manageable by REST APIs for script and 3rd party automation
Improved visibility, control and compliance
• Application aware NetFlow visibility
• Automated log collection with syslog and VC integration

vShield Data Security – September 2011
Overview
New
 More than 80 pre-defined templates for
country/industry specific regulations
 Accurately discover and report sensitive
data in unstructured files with analysis
engine
 Segment off VMs with sensitive data in
separate trust zones
Benefits

Cloud Infrastructure
(vSphere, vCenter, vShield, vCloud Director)
17
 Quickly identify sensitive data exposures
 Reduce risk of non-compliance and
reputation damage
 Improve performance by offloading data
discovery functions to a virtual appliance
EPSEC 2.0 Enables Anti-virus and Data Security Solutions
vSEP virtual
appliance for
data security
 What’s the same
• vShield Endpoint Virtual Appliance (vSEP-VA)
• Thin Agent
• vShield Endpoint ESX hypervisor module
 New Features to support data security
• Support for two or more vSEP-VAs (allows antivirus and data security to run on the same host)
• A vSEP-VA for data security, provided by
vShield
 End user packaging
• vShield App with Data Security (confirmed)
• vShield Data Security (planning stages)
• Both require vShield Endpoint
18
Security Zones
 What do we use security zones for?
• Usual implementation for Servers, multitier applications, and regulated systems
19
Desktop Security Zones
 With this model we can secure our View Desktops in a way that
we can’t do with physical
 New Concept: Desktop Security Zones
• Liam will discuss how he accomplished this with vShield App 1.0
• I’ll discuss how vShield App 5.0 can improve the model as well as additional
capabilities with other vShield products

Use Case 1: Light Clinical Users
 Non-persistent desktop pool
• Dedicated assignment
• Refreshes OS disk on logout
 USB redirect
• For spirometry equipment used for pulmanary function tests (PFTs)
 Multimedia redirect
• For accessing medical data provided by the patient
 Access to specific web sites, not the entire internet
 Deployed mostly in clinical areas
23
Use Case 2: Heavy Clinical Users
 Persistent Desktop
• Dedicated assignment
• All customizations are saved
• Periodic snapshots for quick recovery



No USB redirect
No multimedia redirect
Access to any web site
Deployed mostly in physician and clinical manager offices,
but also accessible in clinical areas.

How Can vShield App 5 Improve Upon This?
32
Application Groups and System Groups
 vShield 5 can now create custom application groups and system groupings
• We can make a group here for all of the DC’s
• We can make 2 application groups
• 1 for TCP applications and 1 for UDP applications
 27 Rules below can be cut down to 3 rules!
• 1 each for Any to DCs –
TCP and UDP Apps
• 1 for ANY – ANY – UDP Apps
(DHCP and NBDG Broadcast)
33
vShield App 5 Improvements
 Nested vCenter Objects
• vShield 5 can now use nest vCenter Objects
• We can create a parent resource pool call “View Desktops”
• This can bring this rule set down to 3 rules.
• We can then create an application grouping for the View related protocols
• PCoIP, JMS, RDP, etc…
• This can bring this rule set down to 3 rules.
• 1 for View TCP Rules
• 1 for View UDP Rules
• 1 for USB Redirection
• These deny rules be cut down from 4 to 2 rules.
34
vShield App 5 Improvements
 Layer 2 Firewalling
• Issue with large flat networks is that broadcast storms can be an issue
• vShield can now do layer 2 firewalling to contain broadcast storms
• Not necessary here at this point, but if the desktop pool gets large enough it
may make sense
35
What Else Can We do Here?
 vShield Edge and/or App
• View Manager Protection
• Management Network Protection
• Server Zone Protection
 vShield Endpoint
• Leverage partner solution for offloaded AV
 vShield Data Security
• In this medical use case, this is a natural solution for scanning for HIPAA
data in an unstructured format on users desktops
• If discovered, vShield App can be used to quarantine or just add additional
protections to those specific desktops
