1 Extending ForeFront beyond the limit TMGUAG ISAIAG AG Security Suite

2 AGAT Security suite - introduction 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. To learn more about our solutions please visit our website at

4 AG Active Sync Filter

5 AG ActiveSync - introduction ActiveSync is a data protocol used to synchronize end user devices with Exchange server. More and more companies encourage their employees to work with their mobile devices implementing Bring Your Own (BYO) strategy to save money and improve efficiency. But from a security point of view, mobile smart phones are in fact mini computers and should be treated from a security aspect as a potential threat.

6 AG ActiveSync - requirement Typically the exchange server is published using ISA/TMG or IAG/UAG. Organizations have the need to control the content published to the client (ie iPhone, windows mobile) to ensure that the content published is compatible with the device security level requirements.

7 AG ActiveSync filter solution AG ActiveSync Filter is a solution for controlling who and what to Sync when users connect to Exchange server with mobile devices. The ActiveSync filter allows configuring publishing rules according to device type and Exchange objects (mail, events, tasks and contacts). In addition, the filter can block publishing of attachments and can perform content filtering.

8 AG ActiveSync - Architecture

9 AG ActiveSync filter features Managing filter rule configuration by device type (iPhone, windows mobile etc). Allowing or blocking by DeviceType (specific phones) or DeviceID (specific users) Allowing or blocking Sync of the following objects: Mail messages, Contacts, Tasks and calendar events Allowing or blocking Sync of attachments in mails messages or events. Filtering by words in subject of mail and calendar events. Allowing meeting requests to be published even when mail is blocked. Filtering by the sender's domain name Optional authentication manager add on solution.authentication manager Support ActiveSync 4.5

10 AG Active Sync - Use cases When publishing exchange data via IAG / UAG or ISA / TMG to mobile devices and there are security requirements to block documents / attachments from syncing to mobile clients. A need to block class types (mail, task, contact or event) from being synchronized. Blocking mails or events by words in content. Restricting less secured phones from syncing mails/attachments Blocking internal mails from being synced

11 AG ActiveSync Authentication Manager

12 General description The Authentication manager is a solution for identifying users using ActiveSync without Active Directory. It is needed when there is no active directory user & pass management (and typically use certificate authentication ). The solution forces the ActiveSync to authenticate against the manager instead of active directory

13 AG Authentication Manager - Architecture

14 AG Authentication Manager - Features Strong Security level solution with something you have and something you know. Zero client installation Create user name and password Change mobile device by user Change password by user User management Configuration of User name and password policy The solution is an optional add on to the AG ActiveSync filter

15 AG Authentication Relay

16 General description The Authentication Relay filter allows users to authenticate using a digital certificate when the application is protected by more than one ForeFront server in a cross domain architecture. The solution does not require any domain trust relationship between the front and back domains.

17 AG Authentication Relay (cont) The solution is based on two web filters: In the front server Relay filter signs the user’s name (after being authenticated by ISA) and time stamp and submits the signed data in the request header. In the back server the Consumer filter verifies that the message was received from the front ISA and then performs the authentication to the required application...

18 AG Authentication Relay (cont) Architecture Option A- Basic Authentication Relay

19 AG Authentication Relay (cont) Architecture Option B- Strong Authentication Relay

20 AG Authentication Relay – Use cases When more than one ISA is protecting the application and smart card authentication is needed. When there is a single front end ISA in the external domain protecting several sub-networks that are using ISA. Typically when using IAG as a gateway and several ISA servers are protecting the internal domains. When you need the client ’ s certificate at the back end of multiple ISA architecture.

21 AG Remote Cert Auth

22 AG Remote Cert Auth- Description Enable to perform certificate authentication using an LDAP that is not in the same domain as the ISA server.

23 AG Remote Cert Auth -Use cases When users are using smart cards to login and the LDAP is in a different domain than the ISA. Typically when organization is securing the LDAP / Active directory in a separate domain then the ISA

24 AG SSO

25 AG SSO - Description Add user certificate and LDAP properties to header request for application authentication.

26 AG SSO - Use cases When your web application is not configured to use Windows authentication and user identity is needed. Properties from LDAP are needed for the application. When you need to pass the client certificate to your internal IIS.

27 AG Multiplexer

28 AG Multiplexer - Description Enable transmitting the user's request via a single point of access to several internal destinations according to user organization unit or group Automatically generate a menu page listing all accessible URLs.

29 AG Multiplexer – Use cases When you need to provide a single point of access to all users to browse to different web applications. When routing users is needed according to the location in the Organization Unit (OU) or Group. Typically when the network is divided into several subnets/domains managed separately. Avoid publishing many internal sites.

30 AG Access Controller

31 AG Access Controller- Description The filter extends the ISA web publishing rule system with additional criteria. Supports configuring the web publishing rules based on user OU or Group. Enables working with an LDAP server that is not in the same domain as the ISA/IAG.

32 AG Access Controller - SSL VPN Allows filtering users that use SSL VPN. Enables identifying the user in SSL VPN in order to prevent anonymous requests entering the firewall

33 AG Secured File Upload

34 AG Secured File Upload- Description Fast file content verification Verify that the extension of the file matches the file content Pass file to antivirus to check virus in content Block dangerous content before reaching internal site.
