Improving security and robustness of Cloud, IoT, and Internet Services

For over two decades, Secure Sockets Layer (SSL) and its successor Transport Layer Security (TLS) have been responsible for securing the communication in the network and between smart devices. The history of these technologies has been marked by significant cryptographic breaks and implementation flaws with exploits wreaking havoc upon enterprises and the public.

TLS v1.3 is a huge leap forward for web based encrypted communication with improved security, and performance compared to its predecessors. In these early stages of TLS v1.3 deployment and with the rise of encrypted traffic volume, it is prudent to gain realistic, preemptive and actionable intelligence through performance/scalability as well as negative testing of the services that leverage this latest version of transport layer security.

Fuzz testing delivers randomness as part of testing strategies that can reveal undetected bugs and compromises that would otherwise get exploited to breach your defenses.

The Meltdown and Spectre vulnerabilities were announced publicly on 3rd January 2018 and these vulnerabilities can affect a multitude of products.

Arbor has provided the following article ID 4149 at the Arbor Support Site. Whilst it is early days, engineering are exploring the possibility of a software patch, once the performance impacts of such a patch are better understood we will be able to further communicate an updated response.

Expands VAR Program in Australia

PlexNet Will Offer Award-Winning App-Centric Infrastructure Performance Management Solutions to Australian IT Organisations & Service Providers

October 10, 2017Virtual Instruments, the leader in application-centric infrastructure performance management, today announced its sales expansion into Australia with the appointment of PlexNet, a specialist in networking, application, infrastructure and security testing and analysis, as its newest value-added reseller (VAR) and professional services partner.

PlexNet specialises in bringing advanced storage and network testing technology from around the globe to the Australian market, and will have full distribution rights for all of Virtual Instruments’ app-centric infrastructure performance management solutions, including the VirtualWisdom infrastructure performance monitoring platform and the Load DynamiX Enterprise storage performance testing and validation platform.

Full access to your 10G copper network

The networking industry is starting to migrate to higher network speeds, such as 10G on copper networks.

That's why PlexNet is is proud to introduce the first 10GBASE-T TAP in the industry from ProfiTap. This TAP gives access to all information on a 10G copper line, making your monitoring equipment perform at its full potential.

It seamlessly integrates with existing copper networks, and is a secure device with a permanent network link guaranteed. Moreover, the TAP bypasses data in case of power failure.

Are Network Connectivity Problems a Thing of the Past?

Every year, networks become more reliable. New standards promise interoperability, new devices simplify configuration and advanced monitoring solutions offer to detect problems before users are impacted. IT departments are entering an era where problems will be a thing of the past.

Or are they? A research study of over 300 network professionals in large- and medium-size organizations found that:

  • Network professionals spend about 25 percent of their time handling escalations instead of working on key IT projects
  • 48 percent of all organizations average longer than half a day to close trouble tickets
  • 46 percent of all organizations are under pressure to reduce the time it takes to close trouble tickets

Spirent TestCenter Scales to 768 100G Interfaces

Independent test to validate the performance and scalability of H3C's data center core switch

Data centers keep growing in two ways: They’re larger, with more servers connected than ever before, and they’re faster, with server NIC speeds of 10 gigabits and higher now common For the core switches that tie everything together, one requirement stands out above all else: Scale to unprecedented heights

That’s exactly what H3C has done with its S12516X-AF data center core switch, setting a new world record by demonstrating the highest bandwidth capacity for a single switch with 768 100G Ethernet interfaces.

Providing visibility from the data plane plus enabling tool chaining as part of an advanced health check methodology is explained in this video. Based on the PFS4204 (or what was once the VSS vBroker 420) this same methodology can also be used with the PFS2204 (or VSS vBroker220). Architecting and deploying this solution can be done with the help of PlexNet. 


The OneTouch AT network assistant is an automated network troubleshooting tool that empowers IT professional teams to effectively validate, and troubleshoot Ethernet and Wi-Fi access networks. The tester incorporates dual copper and fibre optic test ports to facilitate troubleshooting of 10/100/1000 Mbps twisted pair and 100/1000 Mbps fibre Ethernet networks.

The dual ports simplify inline packet capture and VoIP monitoring by eliminating the need for mirror ports or taps. For troubleshooting Wi-Fi networks the OneTouch AT G2 tester incorporates an 802.11ac dual-band Wi-Fi radio with a 3x3 antenna. When connected to both wired and Wi-Fi networks the tester displays test results side-by-side on a single page to aid in problem domain isolation.
