Gigamon’s inline bypass threat prevention helps to secure the network data over faster networks as well as the key benefits of the inline bypass functionality. How serious are the security implications of the introduction of more data over faster networks? When you introduce more data over faster networks such as 10GB, 40GB and 100GB, your existing security tools The GigaSECURE Security Delivery Platform The inline bypass tool aims to increase security without compromising network availability. A diagram of inline tools. Kumarsamy says these present challenges for both network and security teams may not have the capacity to handle these high speeds and therefore will not be able to analyse all of the network traffic for threats. This also results in the degradation of the security tools performance and renders them ineffective. The end result is that not all the hidden threats in the high-speed networks are detected. odern enterprises rely on high-speed networks to increase productivity, find innovative solutions and enhance collaboration. However, these increased network data rates and resulting network upgrades can have major consequences for security administrators, especially those who rely on best-of-breed inline threat prevention tools. M Here, Sam Kumarsamy, Senior Product Marketing Manager at Gigamon, outlines the main implications of introducing more www.intelligentciso.com | Issue 03 Inline tools (as shown in the provided diagram) present the following challenges for both network and security teams: • • • • • • • Introduces multiple points of failure Physical interfaces must match the network Degrades network and application performance Wastes cycles on traffic it cannot analyse Does not scale to network speeds Disruptive to upgrade or replace Cannot be moved to or from out-of-band operation (detection vs prevention) What are the advantages of the platform increasing network visibility? By providing pervasive network visibility across public cloud (Amazon AWS and Microsoft Azure), private cloud 65 Gigamon, the company leading the convergence of security and network operations, is offering a solution to this conundrum with its inline bypass threat prevention. Part of the GigaSECURE Security Delivery Platform – a next-generation network packet broker that has been purpose-built for security – the inline bypass tool aims to increase security without compromising network availability. It works by enabling operational staff to select and distribute specific traffic of interest across multiple inline security tools. Why should organisations not rely on inline tools?
