By Cisco Systems

This paper introduces the new Layer 3 network virtualization solution Easy Virtual Network (EVN). It discusses the need for enterprise network virtualization and compares EVN with the traditional solutions. In-depth architectural information as well as the new provisioning syntax is included to get users fully familiarized with EVN at first look. Click here for a short video on EVN

Lippis Report 165: Network Security in a Virtualized World

January 31st, 2011

nicklippis.jpgThere are powerful market forces changing IT delivery. IT application delivery is becoming increasingly centralized thanks to data center server virtualization plus mobile and cloud computing. Desktops are being virtualized, too, thanks to network speeds that deliver low latency and high bandwidth, creating a thin client user experience that is indistinguishable from a thick client but at lower desktop management cost. One serious implication of this concentration of IT in data centers is that a new IT security model is needed as mobility brings greater threat exposure while virtualization changes traffic patterns and the rules of security appliance placement. In this Lippis Report Research Note, we present a new model for IT security in the virtualized mobile and cloud-computing era.

Lippis Report 163: A Multi-Vendor Security Management Approach via a Cisco SIEM Ecosystem

December 13th, 2010

nicklippis.jpgIn an effort to offer a multi-vendor SIEM (Security Information and Event Management) solution, Cisco is placing its SIEM product, CS-MARS, in end-of-life and in its place, offering the industry its first SIEM ecosystem. Cisco acquired MARS six years ago in December 2004. MARS provided traditional event management and security monitoring along with limited forensic capabilities and compliance reporting. But the market demanded a broader cross-vendor SIEM solution rather than a SIEM focused primarily on Cisco products. In response Cisco has launched a SIEM ecosystem to support deep event monitoring, forensics and compliance reporting across a heterogeneous enterprise network. IT has also expanded the role of its Cisco Security Manager or CSM to support policy management and troubleshooting across a wider range of Cisco products. In this Lippis Report Research Note, we examine the new distribution of security responsibilities that now stretch across Cisco CSM and its new SIEM ecosystem with an eye toward stronger defense of IT assets.

Borderless Network Access A Simplified Approach to Information Technology Access

October 5th, 2010

By Nicholas John Lippis III

Network access has evolved rapidly as IT business leaders have embraced new network technology. Access methods such as wired, Wireless Local Area Networks (WLANs), and mobile plus Virtual Private Network (VPN) methods have flourished over the past business cycle. In addition, a plethora of new endpoint devices have emerged using multiple access methods. But all of these network access approaches have evolved at different rates resulting in siloed networks that do not interact with each other, thus increasing IT operational cost and decreasing application portability and flexibility with user experience suffering. In this paper, we offer a new unified approach to network access that is based upon a thoughtful five-phase method to enable IT business leaders to simplify management, increase user experience and decrease operational cost.
