Why should you care ? • OCS LIA is the first technical integration that provides a true unique selling proposition when combining a Enterasys (NAC) solution with a SIEMENS Enterprise Communications UC solution ­ even using standard protocols and API´s noone in the market is able to provide a similar solution ­ a unique value in projects and RFP´s ­ and still open to other vendor´s infrastructure as Enterasys NAC does support this inherently • It provides a tangible value to the customer that results in a lower TCO (through lower OPEX) and a higher security along with visibility into the IT infrastructure • The solution is not limited to VOIP only. A professional services based integration into any asset/inventory database at the customer site is always possible: the result is IT workflow integration, reduced operational costs and a loyal customer
    3. 3. © 2008 Enterasys Networks, Inc. All rights reserved. What does it for you ? • Automatic inventory and location service reduces risk of operation of non­compliant end­devices with invalid configuration or software release. • Automatic adaptation and location-based configuration of end­ devices and usage of special functionalities (e.g. configuration of speed dial button) • IP phone monitoring Detecting non­compliant and compromised end­devices • Automatic authentication and authorization Warranty of secure, reliable and high­quality operation of real­time applications through automatically assigned QoS-parameter and security profiles (ACL and VLAN) • Finally the use of this solution provides the following value add: • Reduces administrative effort and costs • Increases protection and reliability of real­time applications • Minimizes the risk of attacks and the probability of outage • Increases compliance to enterprise’s security policies • http://www.enterasys.com/company/literature/auto-voip-deploy.pdf
    4. 4. © 2008 Enterasys Networks, Inc. All rights reserved. 4 What is NAC ? • A User focused technology that: ­ Authorizes a user or device (PC, Phone, Printer) and ­ Permits access to resources based on identity authentication of the user (and/or device) as well as based on the security posture of the device along with location and time ­ The parameters are set in the so called Pre-Connect Assessment (aka Health Check), i.e. before connecting to the infrastructure ­ However, during normal operation, regular checks should be conducted as part of the Post-Connect Assessment
    5. 5. © 2008 Enterasys Networks, Inc. All rights reserved. What do you need to deploy OCS LIA ? • Enterasys Network Access Control NAC Version 3.1.2 or above ­ at least implemented in discovery mode (with MAC authentication (802.1x can be used too) enabled on the access sitches and access points) using a default autorization for all endpoints ­ along with professional services from Enterasys to implement the solution and the OCS LIA middleware • Siemens HiPath Deployment Service DLS V2R4 ­ supporting OpenStage and Optipoint VOIP endpoints in both SIP and HFA mode ­ Additional location service licenses for each device that should be supported for this feature ­ Along with professional services from SEN to properly setup up the DLS (also for web services usage) and optionally configure the infrastructure policies 5

Service and event architectures make enterprise computing more effective and flexible than traditional, monolithic "stovepipe" systems.

    12. 12. © 2008 Enterasys Networks, Inc. All rights reserved. OCS LIA Integrator/Middleware – General Features • Synchronize endsystem data from NetSight (NAC) database to HiPath DLS • Synchronize VoIP phone number, type and SW version to NetSight endsystem database • Detect HiPath DLS restarts (for full re-sync) • Detect new phones on DLS side (for individual sync) • Periodic cache cleanup to eliminate old outdated cache entries • Retry mechanism in case of unreachable external systems • Detection of IP mismatch due to VLAN configuration with delayed DLS update (to prevent DLS jobs sent to old device IP) • Flexible logging configuration • Very flexible component configuration • Support of multiple switches • Support of multiple DLS servers
    13. 13. © 2008 Enterasys Networks, Inc. All rights reserved. All device relevant data from NetSight, HiPath DLS servers and switches are collected and cached within the Integrator using an internal cache.

    18. 18. © 2008 Enterasys Networks, Inc. All rights reserved. 18 Corporate & Regulatory Compliance Can I enforce these regulations prior to granting network access? Do I have reporting and auditing tools to verify compliance? NAC – other application scenarios Network Usage Who is using the network infrastructure? Are these users authorized? Does access correspond to organizational role? Workstation Security Does system have up-to-date OS patches? Does every system conform to corporate security standards? Guest Users Does a guest system contain threats? Can I limit access for guest users? Non-Workstation End Systems Is this device what it claims to be? Can I assess its security posture? Can I locate rogue Access Points, hijacked print servers etc?
    19. 19. © 2008 Enterasys Networks, Inc. All rights reserved. IAM - principles • Network technology, distributed computing and the Internet have made it possible to dramatically extend application and information access to users well beyond the typical organizational boundaries. The related security risks, management issues and compliance requirements mus be adressed. o Who is accessing my applications or data? o What are they authorized to do? o Should they have those authorizations? • The tools that allow to answer these questions and maintain control over users and their access make up an identity and access management (IAM) solution
    20. 20. © 2008 Enterasys Networks, Inc. All rights reserved. NAC & IAM integration - Why • NAC is a very useful tool in reducing and controlling the risks to your network infrastructure. However, although it relies on user authentication, on its own this is really no more than a means to identify a device. • The problems of providing each individual user with only the access they are authorised for, and no more, remain. The solution is to tie the authentication process with a robust identity management (IDM) solution, applying network controls to an individual or a well­ defined group. This process is sometimes referred to as Identity Driven Networking (IDN).

    22. 22. © 2008 Enterasys Networks, Inc. All rights reserved. NAC & IAM integration - Advantages • Users are managed centrally in the IDM system for all connected applications (including the network). • The process of managing joiners, movers and leavers can be automated and linked to other key processes (e.g. HR). • Users are automatically added or deleted when they join and leave the organisation. This not only eases the administrative burden for IT support, but also enhances security because users have their access revoked or suspended the moment they leave.

First Win – Higher Education Vertical European School of Management and Technology (ESMT) Berlin, Germany Business Drivers ESMT Solution Case Results…  Segregated data and telecom networks  IP phone inventory and config management was cumbersome  No single view of IP comms infrastructure and devices for admin and management  Enterasys NMS and NAC solution  HiPath DLS  Full policy enabled networking infrastructure with N-Series switches  Voice/Telephony HiPath 3000  Low cost, low effort to integrate ETS and SEN components (within one week)  Total view (location, state, posture) of IP devices throughout network under one management domain  Rules based policy enforcement, error flagging and notification in real time “The open architecture and integration of SEN and Enterasys’ systems required minimal effort from our team. Their professional services experts succeeded in implementing an overarching management system in just one week, saving us a huge amount of work while at the same time making communication more secure.” Thomas Giese, IT Network Services for ESMT.
