How To Make The Cloud Security Experience As Safe As Possible?
Choosing to migrate to the cloud brings a lot of benefits but it is also extending its attack surface. How then secure the migration to the cloud?
Many companies are adopting cloud computing in one way or another. Migrating to the cloud can help accelerate the deployment of IT services, achieve immediate productivity, achieve financial efficiencies, and increase business agility. But it is also a vector for extending the attack surface, with the risk of exposing the entire company to threats to its security.
The upward trend in cloud adoption is continuing apace and the market is expected to grow 18% this year to $ 246.8 billion. Networks are becoming more complex as a modern IT infrastructure adopts private and public cloud platforms to better leverage a range of cloud services.
Cloud services used without the IT department knowing: the risk of Shadow IT
Public or private cloud-based services can present many challenges for business security managers. They are confronted with the increasing sophistication of technologies and the multiplication of suppliers, according to the needs of the various services, and which consequently adds to the risks for the security of their company.
The problem is that some cloud services are used without the IT service being informed, bypassing security policies, and therefore beyond any control. This is called Shadow IT. The Gartner has predicted that by 2021, 27% of all data traffic will pass the security perimeter (against 10% today) and would be transmitted directly from mobile and portable terminals to the cloud. This is the promise of insomnia for security managers who are forced to manage and secure the use of ever-growing cloud services across their entire, often global, organization. And to further complicate matters from a security perspective, many do not have central visibility into their networks, which would facilitate identification and risk management.
How to make the migration to the cloud as secure as possible?
While security is at the top of the list of priorities for businesses of all sizes, here are the issues that security managers must address to make their migration to the cloud as secure as possible:
Have accurate visibility in the cloud as well as on the physical network
One of the main consequences for security managers is that cloud environments are dynamic and offer limited visibility. This lack of visibility comes from the fact that the virtual infrastructure of public clouds is now controlled by the central IT teams of companies. Extending to the public cloud, networks are increasingly important, complex and changing so that the security rules applicable to different platforms and technologies must adapt.Tags: network
