A surge in ransomware incidents and cyberattacks has prompted more companies to turn to private cloud.
Unlike a multi-tenant solution, where performance can be hindered because a company is forced to share resources with a “noisy neighbor,” private cloud offers the benefits that come from a single-tenant cloud solution, including data protection capabilities and regulatory compliance. Private cloud also allows more control over cloud resources, increased flexibility and the added security you’d expect from an isolated environment.
However, while private clouds are considered a safer cloud solution, you can still go further for a more robust and complete defense strategy. Here’s how:
Most companies use a traditional perimeter security defense strategy by incorporating measures like firewalls and edge devices to protect the flow of north-south data. But this is no longer enough.
Cyberattacks are getting more vicious and more creative. Hackers can break-in by using back doors, and trusted sources like end users, to bust-in, allowing them to move laterally, spread and affect other systems and quickly take over the network.
The costs of these breaches are reaching exorbitant numbers -- in excess of $3.5 million. And that’s not including the negative effect on a brand’s reputation or the potential impact on shareholders and stock prices.
Fortunately, there is a solution to this problem. And it’s what differentiates some private clouds from others. It’s called micro-segmentation.
Micro-segmentation is the process by which individual workloads are isolated from one another to maintain security and control over traffic that’s traveling east-west within a data centre.
Using virtualisation, micro-segmentation offers much more granular security controls, allowing only whitelisted traffic to flow between any two devices, applications or workloads. If malicious material manages to breach the firewall and attack a virtual machine, for example, micro-segmentation prevents the attack from spreading.
Data breaches are a nightmare that most companies would love to avoid. Unfortunately, it usually takes an incident of epic proportions, like the WannaCry ransomware attack, to remind people of the potential risks.
The best course of action is to prepare for the worst. Which is why you need to go beyond traditional security measures that focus on the perimeter.
Micro-segmentation enables you to protect your most sensitive data. It protects against land and expand attacks, and it supports a zero-trust model and data protection needs. Even if a bad actor gets past your perimeter, micro-segmentation limits what they can do from there.
By incorporating micro-segmentation in a private cloud, you’re combining perimeter protection with more granular isolation of workloads for added protection.
