We have all spent countless hours attempting to become experts on GDPR. If you're anything like me, you still feel a long way from full understanding. Unfortunately, clear or not, the urgency is real.
When I read the warnings that fill our media, and the scramble for information, I'm reminded of the Y2K bug. Just like 1999, we are getting close to a full-scale panic about compliance, fines, and the potential loss of business if we don't make some pretty big changes.
Whilst the eyes of every business are on your IT systems, there is a huge opportunity that you can take advantage of. GDPR is not just about privacy, or incredible fines. It is an opportunity to take a holistic look at your security portfolio, and underline the necessary steps you need to take to become compliant with this major legislation.
Security is a business problem, not an IT problem, and with the support of business leaders you can build on GDPR to create an end-to-end strategy for your IT systems. It's an opportunity to gain much greater visibility of your network, and preparing you for any future changes or possible attacks that may occur.
Getting ahead of growing networks through automation
In the event of a security attack, particularly if malware is involved, IT systems have to be taken offline. This can cost a company millions in lost revenue, and longer lasting damage to its reputation.
The potential sources for security breaches are huge, and that to me is the biggest catalyst for action. Every business is becoming more reliant on connected things, from old operational technology (like energy sensors) to GPS, to the latest connected lighting or locking systems. Your network is an enormous web of endpoints, from the core out to the millions of user devices at the edge, and customer data can travel through any one of them.
Without looking at this entire landscape, and applying some more rigorous security policies, the loss of customer data in the future is almost inevitable.
When I speak to CIOs, I hear a lot about the need to audit the entire network to understand every place that customer data can touch. This is key to GDPR compliance of course, but if we stop there we only tackle half the issue.
To achieve real end-to-end security, CIOs should work towards:
Segmenting the network so that each individual user and device can be reviewed separately
Automating the network configuration using machine learning
Using this combination, we will see machines become wise to individual devices and user behaviours, meaning they will act when a new behaviour recognised. The subsequent actions could be network re-authentication, quarantining, or blacklisting the user or device. All without the intervention of IT staff.
As the network continues to grow exponentially, IT systems are running to keep up. GDPR is just the beginning of a bigger security concern that is never going to go away. To effectively manage endpoint security, end users and user devices in a secure and sustainable way, we can no longer view the network as piecemeal. The network of the future will represent a single ecosystem, with the ability to create unique policies at any time in any location. It's our best chance to get ahead of what's coming.
