User-ID

As enterprises continue to use Internet- and web-centric applications to aid expansion and increase efficiencies, visibility into what users are doing on the network becomes increasingly important. Dynamic IP addressing across both wired and wireless networks, and remote access by employees and non-employees alike have made the use of IP addresses an ineffective mechanism for monitoring and controlling user activity. Unfortunately, todays port-based firewalls rely heavily on IP addresses as a means of identifying and controlling user activity.

Palo Alto Networks User-ID technology addresses the lack of visibility into user activity by seamlessly integrating with enterprise directory services (Active Directory, LDAP, eDirectory) to dynamically link an IP address to user and group information. In Citrix and terminal services environments, User-ID associates the individual user with their network activity, enabling IT to deploy granular security policies. Integration with other 3rd party repositories is enabled by an XML API.

With visibility into user activity, enterprises can monitor and control applications and content traversing the network based on the user and group information stored within the user repository. User-ID enables IT to:

• Regain visibility into user activities relative to the applications in use and the content they may generate.
• Tighten security posture by implementing policies that ties application usage to specific users and groups, as opposed to simply the IP address.
• Identify Citrix and Microsoft Terminal Services users and control their respective application usage.

User-ID gives an administrator complete visibility into the application activity at a user level, not just an IP address level and in so doing, addresses a key requirement in regaining control over the applications traversing the network. When used in conjunction with App-ID, and Content-ID technologies, User-ID enables IT organizations to enjoy unmatched policy-based visibility and control over users, applications and content
