Identity Awareness removes this notion of anonymity since it maps users and machine identities. This lets you enforce access and audit data based on identity. Identity Awareness is an easy to deploy and scalable solution. It is applicable for both Active Directory and non-Active Directory based networks as well as for employees and guest users. It is currently available on the Firewall blade and Application Control blade and will operate with other blades in the future. Identity Awareness lets you easily configure network access and auditing based on network location and:  The identity of a user  The identity of a machine When Identity Awareness identifies a source or destination, it shows the IP address of the user or machine with a name. For example, this lets you create firewall rules with any of these properties. You can define a firewall rule for specific users when they send traffic from specific machines or a firewall rule for a specific user regardless of which machine they send traffic from. Introduction Getting Started With Identity Awareness Page 8 In SmartDashboard, you use Access Role objects to define users, machines and network locations as one object. Identity Awareness also lets you see user activity in SmartView Tracker and SmartEvent based on user and machine name and not just IP addresses. Identity Awareness gets identities from these acquisition sources:  AD Query  Captive Portal  Identity Agent The table below shows how identity sources are different in terms of usage and deployment considerations. Depending on those considerations, you can configure Identity Awareness to use one identity source or a combination of identity sources ("Choosing Identity Sources" on page 43). Introduction Getting Started With Identity Awareness Page 9 Source Description Recommended Usage Deployment Considerations AD Query Gets identity data seamlessly from Microsoft Active Directory (AD)  Identity based auditing and logging  Leveraging identity in Internet application control  Basic identity enforcement in the internal network  Easy configuration (requires AD administrator credentials)  Preferred for desktop users  Only detects AD users and machines Captive Portal Sends unidentified users to a Web portal for authentication  Identity based enforcement for non-AD users (non-Windows and guest users)  For deployment of Identity Agents  Used for identity enforcement (not intended for logging purposes) Identity Agent A lightweight endpoint agent that authenticates securely with Single Sign-On (SSO)  Leveraging identity for Data Center protection  Protecting highly sensitive servers  When accuracy in detecting identity is crucial  See Choosing Identity Sources (on page 43). Identity aware gateways can share the identity information that they acquire with other identity aware gateways. In this way, users that need to pass through several enforcement points are only identified once. See Advanced Deployment (on page 60) for more information. AD Query AD Query is an easy to deploy, clientless identity acquisition method. It is based on Active Directory integration and it is completely transparent to the user. The AD Query option operates when:  An identified asset (user or machine) tries to access an Intranet resource that creates an authentication request. For example, when a user logs in, unlocks a screen, shares a network drive, reads emails through Exchange, or accesses an Intranet portal.  AD Query is selected as a way to acquire identities. The technology is based on querying the Active Directory Security Event Logs and extracting the user and machine mapping to the network address from them. It is based on Windows Management Instrumentation (WMI), a standard Microsoft protocol. The Security Gateway communicates directly with the Active Directory domain controllers and does not require a separate server. No installation is necessary on the clients or on the Active Directory server. How AD Query Operates - Firewall Rule Base Example The steps listed in the example align with the numbers in the image below. 1. The Security Gateway registers to receive security event logs from the Active Directory domain controllers. 2. A user logs in to a desktop computer using his Active Directory credentials. Introduction Getting Started With Identity Awareness Page 10 3. The Active Directory DC sends the security event log to the Security Gateway. The Security Gateway extracts the user and IP information (user name@domain, machine name and source IP address). 4. The user initiates a connection to the Internet. 5. The Security Gateway confirms that the user has been identified and lets him access the Internet based on the policy. Captive Portal The Captive Portal is a tool that acquires identities from unidentified users. It is a simple method that authenticates users through a web interface before granting them access to Intranet resources. When users try to access a protected resource, they get a web page that must fill out to continue. Figure 1-1 Captive Portal Login The Captive Portal option operates when a user tries to access a web resource and all of these apply:  The Captive Portal is selected as a way to acquire identities and the redirect option has been set for the applicable rule.  Unidentified users cannot access that resource because of rules with access roles in the Firewall / Application Rule Base. But if users are identified, they might be able to access the resource. When these criteria are true, Captive Portal acquires the identities of users. From the Captive Portal users can:  Enter an existing user name and password if they have them.  For guest users, enter required credentials. Configure what is required in the Portal Settings.
