Best Practices vs an Assessment
• Best Practices
• A Security Assessment
• Lock your doors at night
• Lock your windows
• Enable your home alarm
system
• You’ve followed best
practices and you’re safe!
Or are you?
• Your locked doors use an
easy to pick lock type
• Your door frame is thin
and one kick could open it
• Your windows can be
unlocked from the outside
with a screwdriver
• Your phone line can be
cut stopping your alarm
from reaching the police
A proper security assessment validates the implementation of a
best practice—and often reveal many weaknesses!

What does an Audit consist of?
• An audit usually takes the form of a “UC
Penetration Test”
• It typically consists of the following process:
• VIPER will review the business and understand VoIP/UC
application flow
• Will tailor a set of unique security test cases, for penetration
testing, that are unique to that customer’s infrastructure
• Perform network discovery and reconnaissance
• Will spend 1 – 5 weeks doing technical security testing
• Will develop the security report, typically 1 – 2 weeks

The SBC Protects & Defends the
Avaya Core
• The SBC is not just about SIP Trunks and
Remote Endpoints – it’s about Avaya’s future.
• Acme, Sonus, and most other 3rd party players are
moving into the Enterprise with SBC’s –AND- with
Session Management offerings.
• Allowing 3rd Party wins with SBC deals opens the door
for them to capture the Core with their SM offerings and
sequenced applications before it ever gets to an Avaya
system
• Selling the Avaya SBCE protects Avaya’s Core
Business and extends Avaya Aura solutions with secure
and borderless Enterprise communication applications.

‘Rules of Thumb’
•SIP trunking usually 5 users per session
• Must account for higher ratio in small
• Remote Worker must consider both
On-net and off-net requirements
• Remember Encryption Services
impact capacity
©2013 Avaya Inc. All rights reserved
• Session Border Controller
capacities are rated in
Simultaneous Sessions
• A simultaneous session = a
communication session
between 2 SIP endpoints
• Can think of it as analogous to a
DSO in the ‘old world’
• Key for engineering is to
understand the numbers of
sessions required in the solution
• For Secure SIP trunking, look at
the number of TDM DSOs
required
• For Remote Worker, calculate
required call volumes
