Network Security

‘Four Pillars of Network Security’ series: Part 1 – Network Visibility

Alana Wise Blog

For years, the security industry has debated whether outsiders or insiders pose the biggest risk to your network. Today, this argument has become moot as the network demarcation boundaries have been blurred and the threats are all around us.

Hackers are finding gaps before you do

It is getting harder to know who, and what, is on the network accessing services, data and critical assets at any given time. This is all occurring while outside attackers are adapting to new technologies and network weaknesses to bypass the traditional defenses.

Organisations are quickly taking on these new technologies and integrating them into their infrastructures to move them into an ‘always on and everything connected’ digital age. This ubiquitous flow of data drives productivity and performance gains while rapidly adopting the ‘Internet of Things’ (IoT).

It is estimated that there are around 15 billion IoT devices currently connecting to networks around the world, and that number is expected to increase to 30 billion by 2020. This explosion of unique devices has significantly increased the attack surface, as they were not designed with security in mind. This is now exposing organisations to much greater security risks than ever before.

Securing the digital transformation

Of course, organisations have a lot to gain from going through a digital transformation and that development should not have to be impaired due to the increased risks. Security teams have a duty to help the organisations progress into new territories in a way that allows them to be more productive, but remain secure.

To overcome this new emerging issue in network security and control, organisations must improve and expand their network visibility. They require a platform that can discover the comolete parameters of the network and everything connected to it in real-time. This visibility drive is crucial to understand what is connected, who is connected, their location and their behaviour. Armed with this information, organisations then stand a chance of detecting and mitigating the risk that this expanding connectivity presents.

You can’t control what you don’t know

Until now, the ability to generate this visibility has been hampered by the fact that you need multiple technologies correlated together utilizing probes, agents and or taps deployed throughout the network.  Most IoT devices are brainless, which cannot accept agents. This means the IoT devices are not covered by the organisation’s control and presents a weakness that is an easy target and entry point for the criminals. If you can’t see an unauthorized or non- compliant device on your network, you can’t defend against it

Rebasoft leverages network telemetry as a sensor to gain full visibility of the network and everything on it, no matter what type of device it is. Rebasoft tunes into existing network managements systems and network information to deliver real-time visibility of every corner of the infrastructure, its devices and their behaviour – into a single platform without agents, probes or taps. This hollistic visibility is the first step to securing the organisation in the new digital age– seeing what needs to be controlled.

Looking at Part Two – Behaviour Monitoring

In part two, we will discuss how the continuous monitoring of behaviour of everything we have gained visibility of– is the next vital step for a controlled and secure network.
