The importance of network visibility in response to the Internet of Things

NMIS Dash FULL - 700

The Internet of Things (IoT) has led to many businesses capitalising on the computational potential and the increase in data available in everyday objects. The breadth of devices with internet connectivity has been increasing exponentially, CEB (CEBglobal – IoT Security Primer) suggests that the number of connections will grow from 6 million in 2015 to 27 billion by 2025. This increase has led to many new products and many new vendors operating in a market that can be vulnerable to catastrophic attacks. They continue by saying almost 40% of businesses believe that Poor Visibility and Understanding is their leading risk management challenge.

The underlying problem with a network that is considered to have poor visibility is the limited ability to discover everything that is connected to it. NMIS can manage any device that has an IP address, so if it is connected to your network, directly or indirectly, NMIS will know.

With the evolution of devices, there should be equal to greater sophistication in the understanding practices that are used to monitor devices. NMIS collects information from any device on your network and by using the ‘sysObjectId’ variable, it can attribute a vendor to the device from the Enterprise list. The list of vendors is continually expanding, you can peruse the most common list here. However, the true functionality of NMIS is the ability to control new vendors. This process is better explained – Here!

The increased visibility combined with custom thresholding using NMIS, there will be greater control over your network. Users of NMIS will be familiar with SNMP and device modelling, but there are more custom controls that are available. Watch Keith Sinclair (Opmantek CTO) present a webinar that walkthroughs the use of MIBs for custom function, device modelling and custom thresholding. This webinar is located – Here!

opCharts: Maximize Efficiency with Scheduled Outages

Knowing what is on your network is equally as important as understanding how your network operates. An often overlooked component while gathering performance data is accounting for scheduled outages.

If scheduled outages are not accounted for, there can be negative effects on your reporting and your efficiency. Preparation can stop events from expected outages taking up valuable diagnostic time by engineers. Further, the performance metrics will look better while being more accurate.

Using opCharts, scheduled outages can be planned and tracked. By leveraging the powerful tools at your disposal, you can view, display and warn about planned outages. This creates a historical record of start time, stop time and which user created the outage for review purposes. Communication between teams is increased by having a regular maintenance window that is agreed upon by all.
