Authenticates &
authorizes network
access of users and any
network attached device
(IP phones, medical
devices, user devices,
printers etc.).
MDM manages mobile
devices in the context of
which applications
should / should not be
on user handheld
devices, password
management, patch and
software management.
Provides network
security for SIP-based
applications without the
need for a VPN client on
the accessing device.
Single Sign On (SSO) is an
area of access control
that enables users to
login once and/or with
same enterprise
credentials and gain
access to applications
without being prompted
to login again at each of
them and/or without the
need to maintain
different set of
credentials.
Dynamically provisions
the network to contain
the access of users and
the network attached
devices
MDM manages mobile
device data and apps but
NOT control / provisions
the network for access
Controls access of UC
applications (NOT

What is it?
• Network Access with policies, controls
and provisions access to a network
– Including pre-admission endpoint security
policy checks and post-admission controls
over where users and devices can go on a
network and what they can do
• Role-based Access is where access to
the network is given according to profile
of the person and the results of a
posture / health check.
– e.g. in an enterprise, the HR dept could
access only HR dept files if both the role &
endpoint meets anti-virus being up-to-date.

Enterprise Network w/Multiple Policy
Enforcement Locations
• Multiple repositories of
identity information
• Multiple locations of
enforcement points
• Challenges with in providing
access to
• Guest Access
• Contractors Access
• Challenges in implementing
consistent access behavior
across the network
• Challenges with mergers
and acquisitions

February 26-28, 2013 | Orlando, FL
Enterprise Network w/Centralized
Identity and Policy Services
• It is principally the variety of
enforcement devices that
was not foreseen
• Centralization of both
identity and policy
information in a single
location
• Simplification
• Consistency
• Self-service Guest Access
with IT Hands-off
• Contractor Access

February 26-28, 2013 | Orlando, FL
Why is it important?
1. Define roles
• Granular Control
• Network operators define
policies, such as roles of users
and the allowed network areas
to access and enforce them
based in switches, WLAN
Controllers etc.
• Enhanced Security
2. Define network access level
• Ability to prevent access from
end-stations that do not meet
security posture requirements
• Regulatory Compliance
• Enforce access policies based
on authenticated user identities

Multi-Host Multi-Authentication
• MHMA is a network switch capability where Identity Engines
separately authenticates and authorizes multiple clients connected to
a switch port
• Each client must complete
EAP authentication before
the port allows traffic from
the users MAC address,
only traffic from authorized
hosts is allowed
• Enables to direct multiple hosts on a single port to different VLAN’s.
Used for separating voice and data traffic on the same port

What is it?
• Mobile Device Management (MDM)
secures, monitors, manages and
supports mobile devices deployed
across mobile operators, service
providers and enterprises.
• MDM functionality typically includes
over-the-air distribution of applications,
data and configuration settings for all
types of mobile devices
• Smart-phones, tablets, mobile printers,
mobile POS devices, etc
©2013 Avaya Inc. All rights reserved
17
February 26-28, 2013 | Orlando, FL
Why is it important?
• Reduce support costs and business
risks
• Control and protect the data and
configuration settings for all mobile
devices in the network
Say YES to BYOD
• Manage devices
• IT can use MDM to manage the devices
over the air with minimal intervention in
employee schedules
• Visibility
• With mobile devices becoming
ubiquitous and applications flooding the
market, mobile monitoring is growing in
importance.
©2013 Avaya Inc. All rights reserved
18
February 26-28, 2013 | Orlando, FL
Typical MDM Solution
• Server & Client Components
• Server component
sends out management
commands to devices
• Client component runs
on device to receive and
implement commands
• Must have an agent
installed and maintained
• Constant 24x7 race after
device and OS updates
• On-premise and Cloud
(SaaS) based solutions

What is it?
• A device or application that governs
the manner in which calls, also
called sessions, are initiated,
conducted and terminated in a VoIP

between phone sets or proprietary
networks that use different signaling
protocols.
• An SBC can include call filtering,
bandwidth use management, firewalls
and anti-malware programs to minimize
abuse and enhance security

What is it?
• Single Sign On (SSO) is a property of
access control that enables users to
login with one set of enterprise
credentials and gain access to
systems without being prompted for
different credentials or login again.
• Maintaining one set of credentials and
reducing multiple logins.
©2013 Avaya Inc. All rights reserved
39
February 26-28, 2013 | Orlando, FL
Why is it important?
• Reduces password fatigue
from different user name
and password
combinations
• Reduces time spent reentering passwords for the
same identity
• Reduces IT costs due to
lower number of IT help
desk calls about
passwords
