Lösungen > Planning and Visibility: A Must For Network Health

A huge finger is currently being shaken at IT, as a new study by Corero Network Security reveals that the majority of teams are not taking proper care of their networks. According to the study’s findings, most businesses fail to implement effective plans to mitigate the impact of a threat or attack, such as a Distributed Denial of Service (DDoS) attack. For those who don’t know, a network-centric DDoS attack can overload a service and leave a system significantly vulnerable as a result.

A number of variables can leave corporate networks exposed and at risk; however, one undeniable cause of this issue is a lack of network visibility. In fact, when survey respondents were asked about the effectiveness of their plans to prevent, detect and mitigate the damage of a cyber attack, 54 percent admitted to having outdated or non-existent network maps. In other words, they had no insight into problematic areas of their networks.

These kinds of conditions are of course risky for sustaining network health and for gaining full transparency into what is taking place within it. It’s enough to have any business owner paranoid, and that’s why a formal strategy is an absolute must.

While a bypass switch is a fail-safe option for preserving uptime, a formal strategy is what will provide seamless network visibility, ensuring that the precautionary measures are in place so that you’ll never have to get to the point of downtime at all. In fact, over half of IT security practitioners surveyed by IBM admitted that they lack a formal strategy to govern their network data. Make sure you’re in the good half.

In order to gain network visibility the infrastructure needs to support it by installing TAPs, Aggregation TAPs and bypass switches at main junctions within the network. The Network Packet Broker fills a major roll by aggregating the network traffic, provided by the different TAP point and feeding the network monitoring tools with the right data. Today network visibility vendors provide 1G, 10G and 40G TAPs while 100G is starting to be available.

But what should be included in your formal strategy? Check back for part two, where we’ll discuss how to build a foolproof strategy from the ground up.

It’s no wonder corporate networks remain just as—if not, more—vulnerable to failure and compromise than ever before. Seventy-eight percent of initial breaches into corporate networks were described as “relatively easy,” according to data from a recently conducted Verizon study.

Between motivated attackers, human errors and dysfunctional or archaic infrastructures, a corporate network can go down, and stay down, leaving a significant dent in revenue and productivity levels. So if IT managers know this, why aren’t they executing a foolproof, fully baked defense strategy? According to research from IBM, over half of IT security practitioners lack a formal strategy to govern their network data.

It’s time to sharpen your network security strategy, and that involves network monitoring and visibility solutions. Over 60 percent of compromised incidents took months, if not longer, to discover—up from 55 percent in 2011 and 41 percent in 2010, also according to Verizon’s findings.

There are plenty of solutions at one’s disposal for countering network liability; There are today several sources for TAPs and aggregation TAPs which can support 1G, 10G and 40G networks which can provide complete network visibility. however, a bypass switch should without question be one of the top tools to support your strategy.

Why a Bypass Switch?
Bypass switch technology is an easily installable solution. If your network goes down unexpectedly or needs to be shut down for any reason (for example, if your network gets hacked or compromised by an outside party and needs to be manually shut down) the solution will re-route traffic while the system is worked on to ensure a seamless flow of traffic. More advanced solutions will also provide remote Web manageability and 1G, 10G and 40G support.

Network vulnerability is easier and more common than ever before; you simply can’t operate without a plan. Be sure to include a bypass switch when strategizing to ensure the continuity of your company’s network.
