Updated:March 20, 2012
Physical boundaries are disappearing. Businesses need to support a mobile workforce and manage outsourcers, all collaborating on a range of devices from PCs and tablets to smartphones. In addition, the changing IT landscape of virtualization and cloud computing demands a new definition of "identity," and more effective protection for valuable information assets that may now reside off-premises. In this Borderless Networks environment, it becomes critical to establish visibility and appropriate access control for all users and devices.
®, the security component of the Cisco Borderless Network Architecture, provides visibility into and control of who and what is connected to the network. Cisco TrustSec allows organizations to embrace the rapidly changing business environment of mobility, virtualization, and collaboration while enforcing compliance, maintaining data integrity and confidentiality, and establishing a consistent global access policy. Cisco TrustSec integrates with the Cisco SecureX Architecture
™ to allow the Cisco security portfolio to take advantage of the network-based identity context for full context-aware firewalling and policy enforcement.
Cisco TrustSec 2.0 Customer Benefits
The Cisco TrustSec 2.0 system release enhances the flexibility of role-based access control for businesses by:
• Simplifying the management of security policy and access control for all users and access types - wired, wireless, and VPN
• Empowering users to securely collaborate on any device, including consumer IT devices like smartphones and tablets
• Enabling comprehensive support of all user needs via complete security lifecycle services, from guest access to security posture, and profiling
• Delivering and expanding on authorization and segmentation solutions that address compliance requirements
• Using the Cisco networking infrastructure as the secure, resilient, and scalable foundation for role-based access control
Cisco TrustSec 2.0 Solution Highlights
Table 1 describes the solution highlights in Cisco TrustSec 2.0.
Table 1. Solution Benefits for Cisco TrustSec 2.0
Unified Policy with Cisco Identity Services Engine Software 1.0
The Cisco Identity Services Engine offers centralized policy creation and provisioning for all network access scenarios - wired, wireless, and VPN. With the convergence of Cisco Network Admission Control (NAC) Manager and Server, NAC Guest Server, and Cisco Secure Access Control Server (ACS) into the same appliance, Cisco TrustSec deployments and the decision to deploy overlay or infrastructure integrated mode is now simplified.
All-in-one-access and policy platform for better operational efficiencies.
Complete Lifecycle Services:
• Integrated profiling
• Guest access
The following Lifecycle Services are integrated on the Identity Services Engine:
• New integrated profiling capabilities automate the identification of wired and wireless devices, from smartphones and tablets to printers and IP phones, enabling organizations to define an access policy for categories of devices.
• Posture support with 802.1X helps to ensure that endpoints do not become a threat vector.
• Guest access features such as sponsor portals and guest access configuration provide flexible access control options for guests, including limiting the duration of access or restricting guests to Internet only access. This capability is now integrated within the Identity Services Engine along with the other Lifecycle Services.
Integrated Lifecycle Services on the same platform enables operational simplicity in deployments and support of user needs.
Security group access expanded platform and deployment support
Security group access - the scalable, flexible method to authorize and enforce users and devices in the network through their roles - now expands to support authorization at the aggregation and WAN layer.
• Tagging and enforcement (Security Group Tags (SGT) and Security Group Access Control Lists (SGACL)) are now supported on the Cisco Catalyst
® 6000 Series Switches enabling policy enforcement at the campus aggregation layer.
• Tagging and control plane propagation of the roles (Security Exchange Protocol (SXP) and Security Group Tagging (SGT)) on the Cisco ASR 1000 Series Aggregation Services Router platforms expand authorization for extranet or WAN aggregation use cases.
In addition, security group access is supported in Cisco Virtual Desktop Infrastructure (VDI) environments as well. VDI users are tagged in the data center after authentication, and enforcement restricts access to the appropriate virtual or physical data center assets.
Simplified, topology-independent method of authorizing branch and extranet users.
Wireless 802.1X enhancements
In addition to the ability to profile wireless devices in the network, wireless deployments now support RADIUS change of authorization (CoA) methods to authorize users to access the network after meeting security policies.
Flexible security services and authorization for wireless users.
