Risk management practice is improved with Public Cloud Adoption

A Survey by Cloud Security Alliance (CSA) in collaboration with Google finds that Public Cloud adoption enhances risk management practices within the enterprise.

According to Businesswire’s article on the subject:

Among the survey’s key findings:

As organizations adopt cloud, they are challenged to evaluate risk. There is no consistency of data classification across the use of cloud platforms and services — only 21 percent of users are utilizing cloud service data classification, and only 65 percent of those users are aligning with internal data classification schemes.

Cloud risk evaluation faces challenges with growing business adoption of cloud. With cloud adoption numbers increasing, more than half (52%) of organizations reported that they did not evaluate the risk of their cloud services being used after procurement as product features or business environments changed.

Tools for quantifying and measuring risk need to improve. Seventy percent of organizations reported less effective processes for assigning risk to cloud assets, with only 4 percent reporting having highly effective practices.

Monitoring, measuring, and reporting is difficult. Thirty percent of enterprises reported that risk scoring systems are used as a directional guide to risk improvement for certain cloud solutions as opposed to measurements that can be relied on for comparison across all cloud services.

The full survey can be found online.

Defender for Cloud support for Azure Cosmos DB now available everywhere

This week, support for Cosmos DB as a supported workload of Defender for Cloud has gone GA (generally available).

Now your cloud native Cosmos DB SQL Core API is monitored and has alerts raised for suspicious activities. As the official page mentions:

Microsoft Defender for Azure Cosmos DB provides an extra layer of security intelligence that detects unusual and potentially harmful attempts to access or exploit Azure Cosmos DB accounts. This layer of protection allows you to address threats, even without being a security expert, and integrate them with central security monitoring systems.

It’s worth noting that:

Defender for Azure Cosmos DB doesn’t access the Azure Cosmos DB account data, and doesn’t have any effect on its performance.

Learn more about it in the official documentation.
