Background & Overview
 Connecting external devices (mobile/computers) to the
corporate network raises security risks related the Active
Directory exposure.
 Typically there is no control over apps installed on
employees’ smartphones and the networks that these
devices are connected to.
 LyncShield is a server side solution with not additional
client install supporting all devices.
 The product is available on TMG or Bastion reverse proxy
Slide 2
Security issues and solutions
Problem
Solution
Connecting non
authorized devices
Two Factor Authentication
Active Directory password Avoid AD credentials on device –
dedicated log in
leakage
Account lockout /DDoS
Blocking false authentication
attempts in DMZ proxy before the
Active Directory
All the solutions are available for both mobile and external PC/ Laptops
Slide 3
[1] - Two Factor authentication
 Based on Device ID sent by client
 Several registration/ enrolment options to enforce access
control policy based on matching the device and the user.
Slide 4
Access Control – Enrollment
 Support several access control policies:
 Automatic Registration – Device ID is registered upon first
use of account.
Two steps registration process:
 Two Step Registration – User registers on internal site and
then must sync within a defined time frame to complete
registration.
 Admin Manual Enrollment – Admin management of user
list using training mode and rejected auditing list.

Slide 7
Access Portal admin
 View approved & blocked users
 Restrict registration and ongoing connection by IP range
 Allow / Block Web app login
 Access Rule black / White list
 Allow / Block guest users
 Number of devices per user
 SMTP notification
 Product settings- Registration, Authentication…
 Two level admin - local domain admin
 Reports & Search

[2]- AD credential protection approach
 Lync Shield introduces a new approach for protecting the
Active Directory credentials
 With Lync Shield the connection to Lync is done by using
dedicated Lync credentials that are created by the user
rather than the regular network Active Directory
credential
 Lync Shield completely eliminates the need to store
Active Directory passwords on the device
Slide 10
Active Directory dedicated login
 The user creates dedicated Lync credentials on a self
service internal web site for use on device, instead of
Active Directory credentials.

Slide 12
Mobile Smart Card solution
 Many organizations that smart card for network login do
not have a username and password for Active Directory.
 LyncShield allows the usage of Lync without the need to
manage Active Directory credentials.
 With the dedicated login solution, the user logs into the
Access Portal authenticating with his smart card from his
network computer and creates dedicated SharePoint
credentials for use on the mobile device.
Slide 13
[3]- Active Directory Account
Lockout protection
 Account lockout can be the result of the following:
 The user changed the Active Directory password, but did
not change the settings on the device.
 The username (without the password) being obtained by a
hacker who tried to log in several times
 Ddos , Dos , brute force attacks- Such attacks can result in
the network becoming unavailable
 LyncShield eliminates these threats by blocking
the failed attempts on the gateway server side,
before reaching the Active Directory
Slide 14
Coming soon- RSA / ADFS / Office 365
 RSA integration
 User will authenticate in a web site using RSA
 User will need to connect device within short time (5
minutes for example) to complete registration
 RSA Authentication will be valid for a limited configurable
time (like one day).
 Two Factor Authentication for Office 365 / Device
registration
 Solution for using Lync with ADFS without breaking
Exchange connectivity
 Solutions planned to be released by end of Q4, 2014
Slide 15
Coming soon- - EWS Protector
 Exchange Web Service Protector is an independent
product securing the Exchange services required for Lync
meeting information
 Offers currently:
 DDos protection/ account lockout protection for EWS
authentication services (available)
 Two Factor Authentication (available)
 Password protection (using Lync credentials and not AD)- to
be released soon (available)
 Filter by operations – allowing only meeting requests (soon)
Slide 16
Bastion
 Reverse proxy forwarding traffic to the configured
backend servers.
 Cross-platform- Windows / Linux
 Pluggable filtering architecture.
 Filters HTTP(S).
 Scalable Event-Driven Architecture.
 Can publish multiple servers in parallel.
 Highly efficient asynchronous architecture.
 Bi-directional content filtering.
Slide 17
Bastion (cont)
 Geared towards full-featured HTTP filtering.
 Most reverse proxy solutions are geared towards web
acceleration.
 Supports many HTTP features and scenarios.
 Chunked, gzip and deflate Transfer-Encodings.
 Pipelining.
 Supports filtering content, blocking content or generating
proxy responses anytime during the filtering chain (unlike
TMG and UAG).
Slide 18
AGAT Security suite - Overview
 LyncShield and MobilityShield are part of AGAT’s Security
suite.
 AGAT Security suite is a set of unique components that
allow extending Forefront (ISA/TMG IAG/UAG)
functionality to solve complex architectures and
requirements, typically implemented in large, complex
and well secured networks.
 The solution is also available on Bastion reverse proxy
without the use of Forefront.
