Why Is East West Traffic Segmentation Necessary?
Comprising more than 75 percent of traffic transpiring on typical networks, east/west network traffic is exclusively server-to-server and machine-to-machine traffic presenting IT security dilemmas that are difficult to resolve. Cyberthreats managing to gain entrance inside a network are the hardest kind of threats to stop. Infiltration of a malicious entity into a network resembles the destruction of a long, twisting domino line – push one over and the rest follow.
Could an external threat to north/south traffic bypass firewalls?
You bet they could. The reason why east/west traffic security does not get the attention it needs is because it’s widely assumed north/south firewalls are invincible. Unfortunately, the war between 21st century malware and cybersecurity programs resembles the MAD (mutually assured destruction) scenario: hackers create new malware, IT experts develop software to stop it, hackers create better malware, IT experts develop better software to stop it, etc. Firewalls are intended to prevent malware from entering a site at the perimeter. But once a piece of malware has managed to infiltrate the network, it is free to roam east-to-west as it likes since there is little focus on security between trusted servers.
Depending on the quality of a threat to a network, some malware may hide meticulously within encrypted data and be missed completely by conventional firewalls.
An unstopped threat may create anarchy in a network and damage it permanently. Consequently, a strong east/west security solution implemented by Pluribus Networks can identify all abnormal traffic types that have occurred on a network and be instrumental in preventing these occurrences in the future. In fact, networking solutions that provide visibility for east/west traffic security answer the question: “What else can I do to enhance my security footprint?”
Software-Defined Networking – Why It’s Still the Buzzword
Separating the data plane from the control plane lets software-defined controllers manage the flow of traffic through multiple network paths without encountering limitations of physical devices and associated proprietary software applications. In addition, the programmability afforded by an SDN network utilizing open APIs allows controllers to define performance and behavior of networks based on running applications. This means if a certain application on the network requires specific resources or performance considerations, it may by optimized by programming the fabric itself.
SDNs also facilitate automation of policy management jobs and configuration to support rapid, dynamic reactions from networks. Pluribus Networks’ Virtualization-Centric Fabric (VCF™) offers cutting-edge segmentation and visibility, eliminating the need to supervise separate, overlay or monitoring networks above an existing, physical network infrastructure. The ability to create virtual networks through segmentation with visibility built-in provides a powerful weapon in the fight to prevent security incidents.
Visibility is everything when trying to secure a network.
With the ability to see DDoS and APDoS attacks, networking solutions for east/west traffic supported by Pluribus Virtualization-Centric Fabric helps to optimize all facets of your company’s operations by providing multilayered security. According to a Ponemon Institute study, Distributed Denial of Service attacks cost most companies an average of $22,000 per minute. Since DDoS attacks generally last about an hour, the possibility of a business losing close to $135,000 due to a DDoS attack is high. However, as every security study states, the best resolution is to prevent these attacks before they begin, or as they are forming.
