Overview
The cyber-attack landscape has rapidly evolved in recent years and the SolarWinds hack, one of the biggest cybersecurity breaches of the 21st century, was the crack. Today, the costs that result from a single breach could reach millions of dollars without any exaggeration. Quite devastating for an organization, right?
To keep up with the sophistication of today’s threats, the traditional models are failing to provide the full visibility and control you need to secure your environment. Moving to the cloud and addressing security and governance matters in a cloud environment brings more complexity for organizations where regulatory rules are constantly changing, and the cost of compliance increases as well. Keeping up with all this isn’t easy.
In this article, we will closely examine how Microsoft Defender, a security model that quickly adapts to the reality of the world we live in, allows all organizations and governmental entities to appropriately secure their environments whether they are on Azure or on-premises. We will also demonstrate how to leverage the cloud security posture management feature in Microsoft Defender to ensure maintaining a proper security posture and being compliant with various regulatory compliance such as FedRAMP, CMMC, and CIS.
We will also showcase how to secure your workloads within the azure environment and on-prem resources such as storage accounts, containers, VMs, and more.
What are the most common security challenges?
Visibility into the security compliances · Increase in number of sophisticated attacks · Complexity of managing a multi-cloud environment
The very first challenge: the visibility into the security compliance
Last year in 2021, the world witnessed progressive cyber-attacks and we all remember the SolarWinds hack where the cost of a breach was estimated to be almost 4.24 million dollars! Building cloud environments brings more complexity for organizations and 92 percent of them are embracing their strategies in the Cloud but very few of them have learned how to maximize security within those new environments.
1. Microsoft Defender For Cloud
Microsoft Defender is an Azure native security service deployed across different types of cloud and hybrid environments. It provides a full security stack in Azure, on-prem, hybrid, and multi-cloud environments as well.
It offers complete management of the security posture in Azure by using a security score and leveraging a standardized compliance security assessment benchmark to evaluate the security of the environment and providing you with a visible score of your security posture as well as compliance for each of those standard controls. It also detects threats and protects your workloads, either if your VM is running on Azure, or on-prem, and even on AWS or GCP. It also provides full support of protection for Azure resources and along with that full vulnerability assessment and management.
Microsoft Defender has the capability of responding to threats when found during the assessment and mitigating the incident and the alert, and those mitigations can be operated either manually or can be fully automated.The response automation can be using tools such as logic apps and can be integrated with other tools such as (sentinel, teams, outlook, ITSM Products such as slack, ServiceNow, or others)

Use asset inventory to manage your resources' security posture
The asset inventory page of Microsoft Defender for Cloud Inventor Cloud provides a single page for viewing the security posture of the resources you’ve connected to Microsoft Defender for Cloud.
- Which of my subscriptions with enhanced security features enabled have outstanding recommendations?
- Which of my machines with the tag ‘Production’ are missing the Log Analytics agent?
- How many of my machines tagged with a specific tag have outstanding recommendations?
- Which machines in a specific resource group have a known vulnerability (using a CVE number)?
