Slide 2
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.
Slide 3
Security requirement and solutions
Solution Requirement
Two Factor Authentication based adding the device factor
Secure external authentication
Avoid AD credentials on device – Dedicated App credentials log
Protect Active Directory password from leaking
Soft lockout in DMZ Blocking false authentication attempts from reaching the Active Directory
Protect agaist Account lockout & DDoS attack
Slide 4
Security issues and solutions (cont)Solution Requirement
Control device registration by certificate or manual admin
Limit Lync to approved / corporate devices
Bind Lync usage to MDM control
Limit Lync to devices with MDM
All the solutions are available for both mobile and external PC/ Laptops
Slide 5
[1] - Two Factor authenticationBased on Device ID sent by clientSeveral registration/ enrolment options to enforce access
control policy based on matching the device and the user.Protects both Lync & Exchange (EWS) – blocking any
request passing to network servers unless coming from an approved device
Slide 6
Access Control – EnrollmentSupport several access control policies:
Automatic Registration – Device ID is registered upon first use of account.
Two steps registration process: Self Service / 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 12
[2]- AD credential protection approachLync Shield introduces a new approach for protecting the
Active Directory credentialsWith Lync Shield the connection to Lync is done by using
App 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
Supports work against Exchange & Lync with one App credentials
Slide 13
Active Directory App login
The user creates dedicated Lync credentials on a self service internal web site for use on device, instead of Active Directory credentials.

Lync App credentials architecture
Slide 15
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 16
RSA integrationMobile users enter their RSA Token authentication code
instead of Active Directory passwordLyncShield verifies password
against RSA Authentication Manager and impersonate user against Lync
Desktop users Authenticate in web site from Browser and than can login from Lync desktop client
Slide 17
[3]- Account Lockout protectionAccount 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
Slide 18
Account lockout protection (cont)
LyncShield blocks the failed attempts on the gateway server side, before reaching the Active Directory
LyncShield offers a multi-site defense approach covering all authentication channels
Unified solution that protects all distributed resources.Failed attempts are counted and stored in a central
database table which is shared by all LyncShield components.
Slide 19
[5] MDM binding
LyncShield can limit the usage of Lync to managed devices only – devices with MDM
Compatible with any MDM solution supporting one of the following capabilities:Certificate enrollmentApplication management (MAM)VPN triggering / control
These are available from most of the vendors around the market including Microsoft Intune, AirWatch, MobileIron, MASS360, Good, XenMobile and more.

Slide 21
VPN support for Lync
MSFTs recommendation is to keep all voice and video traffic going through the Edge and not over the VPN
LyncShield offers an Hybrid solution requiring the authentication to be done over VPN and routing the Video/Audio to go through the Edge over the internet.
Does not require VPN splitting
Slide 22
Lync traffic splitting over VPN
Slide 23
Product architecture - Bastion Proxy LyncShield solution offers as part of the solution the
dedicated reverse proxy Bastion developed by AGAT.The Lyncshield filters are plugged into Bastion to extend
access control and content filtering capabilitiesCross-platform- Windows / LinuxScalable Event-Driven Architecture.Can publish multiple servers in parallel/ mulita channels. Highly efficient asynchronous architecture. Supports high availability deployment
Slide 24
Bastion (cont) Main characteristics :
Geared towards full-featured HTTP filtering.HTTPS - Decrypt SSLSupports many HTTP scenarios: Chunked, gzip and deflate
Transfer-EncodingsPipelining.
Supports filtering content, blocking content or generating proxy responses anytime during the filtering chain (unlike TMG and UAG).
