Top Cloud Security Challenges
Because resources that are hosted by a cloud provider are managed by a third party and can be accessed over the Internet, there are quite a few challenges regarding the security of your cloud environment.
Increased Attack Surface
In the public cloud, you can access all your resources via the Internet. This provides a very attractive attack surface for hackers to probe for vulnerabilities. You can reduce this attack surface and make a cloud platform just as secure as in-house data centers, but you have to configure it correctly to do so. You can no longer just hide everything behind a firewall.
Everything is Software Now
In the cloud, everything is delivered via software. Operating systems and whole servers are virtual. Cloud-native infrastructures can scale dynamically to workloads. Cloud security controls must be able to respond to these changes and protect sensitive data both at rest and in transit.
Lack of Visibility
In most cases, the cloud environment will have to be accessed via the Internet. This means that all the services run on hardware that your IT staff does not manage. Therefore, you need first-class visibility into what is going on in your infrastructure with advanced systems and traffic monitoring.
Granular Access Control
In a traditional in-house data center, protecting your network perimeter with a firewall could prevent a lot of threats and make up for loose network security. In the cloud, users can access data and applications over the Internet. This means ensuring that you correctly configured all access controls is even more important on a cloud platform.
Even if a business chooses only one cloud-based solution, the platform can be complex. But most enterprises need a private cloud solution as well as a public cloud solution. They may also have multiple branches across the world that host on-premise deployments. These platforms must work well together to prevent bottlenecks and errors.
Choosing a cloud platform can also add another dimension to regulatory compliance. A company may have to adhere to regulations such as HIPAA, PCI, and Sarbanes-Oxley, or certain contractual internal agreements. Compliance audits can be difficult unless the right tools are in place.
