Testing your cloud security

As you must know already, all defensive security measurements must be tested to confirm whether the implemented controls are effective, but also to detect whether there is any potential hole that can be exploited by attackers.

Therefore, in this section, we will explore the best tools that you can use to monitor your cloud in terms of availability and vulnerabilities to confirm that your controls are effective, but also to determine whether they are in compliance with a given regulation.

Azure Security Center

Azure Security Center is a must if you have your cloud hosted with Microsoft, as it allows you to assess the security state of all your cloud resources, including servers, storage, SQL, networks, applications, and workloads.

As seen in the following figure, here, you can visualize your security state and even improve it by using Azure secure score recommendations:
