1 Best Practices Guide I Data Center COMMAND YOUR DATA CENTER How to Thrive In the Changing Landscape The demands to virtualize, scale, and implement new applications while conducting security, forensics, compliance and performance monitoring activities are adding to the list of hurdles facing IT teams. These network visibility best practices provide insights into the solutions needed to manage and optimize network monitoring to solve many of these challenges.
2 CHALLENGES DRIVING THE NEED FOR NETWORK MONITORING* NETWORK VISIBILITY PRESSURES As the network becomes critical to the success of an organization, network security and performance groups are challenged to gain greater insight into that network. Network administrators must enable access to network traffic for the monitoring tools used by these teams. IT trends such as increased reliance on SaaS applications, BYOD and the transition to 10/40/100G are also increasing complexity and vendor diversity within the data center. Meeting these challenges calls for an increasingly broad set of monitoring tools, which frequently require visibility into specific network segments or types of traffic. For these tools, 100% visibility of network traffic is vital to effectively securing and monitoring the network. *Source: Net Optics survey of 1,235 IT professionals conducted at RSA 2013 Conference 31% 9% Monitor and manage application performance throughout the network Meet regulatory compliance requirements 16% 9% Improve network bandwidth utilization Improve the accuracy of network design 11% 8% Improve cyber-threat identification and response Enhance existing and future network topologies 10% 6% Optimize performance of network hardware Evaluate ability of network to accommodate additional applications and traffic
3 OLUTION FAIL-SAFE ACCESS AND 100% VISIBILITY Net Optics access products, including Network Taps and Bypass Switches, provide passive and fail-safe access for tools deployed in either inline (IPS) or outof-band (IDS) configurations. Utilizing Network Taps, Aggregation and Taps, Bypass Switches, and Virtualization Taps, network admins are able to evolve beyond zero or limited SPAN visibility. 100% network visibility allows teams to analyze the specific traffic of interest they require in order to monitor and secure the network. PHASE I: NO VISIBILITY Network management teams initially lack visibility into the network and the insight needed for effective security and performance monitoring. PHASE II: SPAN / PORT MIRRORING VISIBILITY Using SPAN or Port Mirroring provides limited visibility into the network but is susceptible to oversubscription and mis-configuration. PHASE III: 100% VISIBILITY Net Optics Access products provide a Visibility Layer to the network to achieve 100% visibility.

4 OPTIMIZATION OF NETWORK SECURITY AND PERFORMANCE MONITORING TOOLS When network monitoring solutions are deployed as isolated point solutions or configured to receive non-optimized traffic, they are susceptible to degradation in their efficiency and effectiveness. Increasing network speeds and application diversity also creates new hurdles. Network administrators are faced with the challenge of ensuring that their network monitoring infrastructure is manageable, comprehensive and optimized to perform under these diverse loads without affecting network performance.

5 OLUTION CENTRALIZED CONTROL AND OPTIMIZATION Net Optics Total Visibility Solutions provide a layer of control as to which tool receives specific traffic. Capabilities such as flow-mapping, deduplication, aggregation, filtering and loadbalancing optimize network traffic before it reaches a monitoring tool. The benefits of adding this Visibility Layer to your deployment include: manageability, reduced overhead, increased utilization and better performance from your entire set of network monitoring tools. High Availability (HA) configurations are also possible for your monitoring deployment, a major benefit for networks under pressure to deliver always-on performance.

6 CHALLENGE S SYSTEM/VM ADMINISTRATOR S MOST IMPORTANT SECURITY CHALLENGES* MONITORING INTER- VM TRAFFIC WITH EXISTING SECURITY AND PERFORMANCE TOOLS Data Centers are on the path to either converged or full virtualization. However, many monitoring tools designed for traffic flowing over the physical network don t have the ability to inspect traffic between two Virtual Machines. Not only does this situation leave security administrators blind to possible malicious activity within this growing segment of the network, but achieving an integrated approach to total network visibility becomes next to impossible. Achieving visibility into your virtualized traffic that is comparable to that of your physical network requires extensive redeployment or the purchase and implementation of an entire new set of virtualization-specific tools. 1 Preventing sensitive data from creeping into less secure virtual environments Maintaining compliance with regulatory and audit requirements 2 *Source: Net Optics survey of IT professionals conducted at VMworld2013 Conference 3 Integrating virtualization security with current physical security tools and practices

12 CHALLENGE RAPIDLY EVOLVING NETWORK THREATS Network security demands Defense in Depth, an approach that keeps the network ahead of proliferating threats. Defense in Depth calls for multiple security systems working together and delivering instantaneous feedback for conducting forensics. Defense in Depth strategies combine, cascade and join multiple security solutions to work in concert transparently. Each component of this solution addresses specific risk factors and attack vectors. The next evolutionary step in Defense in Depth strategy will address the need for various security layers to respond dynamically to a detected threat. They can then reorganize or re-deploy in the ideal configuration for eliminating or minimizing that threat.

13 SOLUTION AGILE SECURITY RESPONSE Security-Centric SDN: A Scalable, Cost-Effective Security Architecture Net Optics Security-Centric SDN enables the scaling of existing security and other monitoring tools without a costly overhaul. An organization can now achieve total network visibility and protection across the entire breadth and depth of physical, virtual, and private cloud environments. This new approach separates network elements from security and monitoring devices; it also enables automation and provisioning of monitoring applications and tools based on real-time traffic behavior. Security-Centric SDN provides end-to-end network monitoring and improves security, along with simplifying operation. Security-Centric SDN marries an SDN controller with NPBs and a customer s chosen security tools. NPBs, with their ability to chain solutions, integrate multiple systems, and distribute traffic, provide the ideal means for provisioning a dynamic response. Such chaining of security solutions supports and enables Defense in Depth. It embodies dynamic attack monitoring; the use of NPBs for traffic distribution; and use of the network controller for assessing the network, provisioning SDN, and reacting to network activity.
