Why choose Defender CSPM?

The Cloud Security Posture Management is one of the key elements of Microsoft Defender for Cloud. This comprehensive solution provides visibility, protection, and governance for cloud resources on Microsoft Azure, AWS, and Google Cloud Platform. The CSPM continuously evaluates the cloud's security posture, identifies and corrects misconfigurations, and ensures compliance with security standards and regulations.

Defender for Cloud offers some basic CSPM features, such as resource discovery, security tips, and Secure Score, for free. However, to access advanced features such as Attack Path Analysis and Cloud Security Explorer, you must activate the optional Defender CSPM plan.

This optional plan, with its wide range of features related to the protection and active governance of its resources “in the clouds”, can make Defender for Cloud one of the best CSPM solutions currently available on the market.

How? Let's find out in the next sections.

What to look for in a CSPM solution

But first let's do a proper review.

Cloud Security Posture Management (CSPM) is a broad category of tools that help companies strengthen the security of their cloud environment. Today there are numerous CSPM tools available on the market, all with different characteristics and strengths that must be evaluated to understand which solution best suits your needs.

However, to be truly defined as a quality CSPM tool, it must guarantee users full visibility and control over the cloud solutions used by the company, including the SaaS, IaaS and PaaS infrastructures and a whole range of features that have over time become an essential standard for these solutions.

So let's see together what you should definitely look for in a CSPM solution worthy of the name.

Continuous monitoring and compliance

Lack of visibility is one of the main problems with cloud environments, hindering effective control and the ability to intervene promptly. Without continuous monitoring, obtaining complete visibility is impossible, which is why this is one of the fundamental characteristics of a CSPM.

It's important to ensure that the tool can monitor as many events as possible on all cloud platforms in use. These events include misconfigurations, access to systems and data, attacks, and regulatory compliance.

Often, professionals neglect compliance monitoring when choosing a CSPM, and are then forced to integrate third-party solutions to fill this gap or completely replace the tool.

Contextual visibility and insights with Defender CSPM

Automated policy enforcement and threat response

One of the main issues in managing multi-cloud environments is the growing skills gap. Cloud solutions are evolving rapidly, the number of environments used by businesses is constantly increasing, and it's becoming increasingly difficult for security teams to keep up with these changes.

Companies suffer from a shortage of qualified professionals, while available professionals often lack the necessary skills. Additionally, with the growing number of cyberthreats, security teams don't have the time and resources to monitor and respond to every threat.

For this reason, it is essential that the CSPM has functionality for automated policy management and incident response.

  • Security policies allow the system to automatically respond to the most common threats (e.g. insecure data sharing) and to prevent errors.
  • Automated remediation allows the system to initiate corrective actions to reduce the impact of an incident.
  • This functionality also allows the IT team time to analyze threats, investigate attacks, and plan future security strategies.

A modern CSPM must include all of these features to ensure effective protection and reduce the complexity of managing cloud security.

Managing security policies and simplifying compliance with Defender CSPM

Centralized dashboard and reporting

In multi-cloud environments, one of the main problems is that the controls are distributed across multiple platforms. As a result, the IT security team must configure each platform separately in accordance with corporate security policies.

First, this inevitably leads to errors and consumes too much time. Second, different cloud platforms offer different security features, and some may not even have the necessary controls.

The CSPM solves these issues by providing a centralized dashboard. It is now possible to configure all platforms from a single point and ensure that security rules are consistent across multiple cloud environments.

In addition, reporting provides a global view of security trends in the organization and provides insights that might otherwise remain hidden.

Monitoring your security posture with Defender CSPM

Threat Intelligence and Vulnerability Management

The multitude of data coming from various cloud environments can be overwhelming for human perception and difficult to analyze. The threat intelligence capabilities of CSPMs can help the IT security team manage this challenge.

Threat intelligence analyzes all event logs from different cloud environments and classifies them according to their severity and urgency. Subsequently, this processed data is presented to the IT security team for a timely response. It helps to organize work, reduce its burden, and allocate team time more efficiently.

Vulnerability management provides the necessary controls to make timely and appropriate decisions on any flaws in your security posture.

Scalability and performance

Scalability is an important feature of any cloud solution, including CSPM. First, many companies are constantly growing. Second, many companies regularly explore new cloud environments that emerge on the market. The CSPM must be easily scalable in terms of the number of users and integrations.

Performance is another important aspect to monitor. If the increase in users causes CSPM to malfunction, this is not a good solution for your company.

Improving business data security with Defender CSPM

Intuitive interface and ease of use

Last but not least, the CSPM should have an intuitive and easy-to-understand interface. The main task of this tool is to lighten the workload of the IT security team.

If the team spends too much time searching for the necessary data or checking important information, the CSPM will not be able to save time and resources.

Foundational CSPM vs Defender CSPM: a comparison

Now that we know what to look for in a CSPM solution that deserves our attention and money, here's the good news: Defender for Cloud offers all the features we mentioned above and even more.

All we need to understand is: What functionality do we need?

The CSPM features in Microsoft Defender for Cloud are available both in a free version (called Foundational and already available in Defender for Cloud) and in a paid version, depending on the required capabilities.

The Foundational CSPM level is designed to provide essential security functionality at no cost. When Defender for Cloud is activated, we will automatically get Foundational CSPM capabilities for all resources in the subscription.

This level is ideal for organizations that want to get started with cloud security without incurring additional costs. It offers a solid foundation for improving safety posture and ensuring compliance with various standards.

Among the free features we can find:

Features in Foundational CSPM

Why Defender CSPM: 'agentless' features and their benefits

One of the main advantages of the Defender CSPM plan that we only mentioned in the previous section is the presence of agentless scanning capabilities. These allow cloud resources to be analyzed to identify vulnerabilities, sensitive data, secrets and exposures, without having to install additional software.

These features are especially useful for cloud-native services, such as PaaS databases and storage accounts, that don't support the installation of agents or require minimal management.

When combined with contextualized cloud posture management (CPM), attack path analysis, and security risk analysis, features can help improve the overall cloud security strategy and play a critical role in protecting containerized applications, Kubernetes environments, VMs, and data.

By offering a comprehensive approach to cloud security, they adapt efficiently to the growth and complexity of their infrastructure, ensuring a holistic security posture. In addition, all of these benefits are included in the cost of the plan with no additional charges.

In addition, they offer significant advantages in terms of scalability, integration, reduced complexity, proactive threat mitigation, improved efficiency, and cost savings. Easily scaling with your company and its cloud infrastructure, they integrate seamlessly into different configurations, eliminating the complexity of managing individual agents. By prioritizing proactive threat detection through continuous monitoring and real-time analysis, they facilitate rapid responses to security threats.

The absence of individual agents improves efficiency and allows IT teams to focus on strategic planning. Adopting agentless functionality eliminates the need for agent software maintenance, resulting in cost savings.

By maintaining their active state and using them regularly, organizations can remain vigilant against evolving risks and promptly address potential vulnerabilities. This enduring commitment to using these capabilities is crucial to establishing a resilient and secure cloud environment that can adapt to changing circumstances.

The Defender CSPM plan includes four agentless features by default, which we present with the following table.

Agentless features in Defender CSPM

Feature Description
Agentless Container Posture and Container Registry Vulnerability Assessment Containerization has become a standard approach for building, packaging, and deploying applications. Defender for Cloud provides agentless posture assessment and container registry vulnerability scanning (both Azure and third-party), enhancing the security of containerized applications and enabling continuous threat mitigation. The service also includes near real-time scanning of new images and is available not only for Azure but also for AWS and GCP.
Agentless Discovery for Kubernetes Defender for Cloud offers agentless discovery features for Kubernetes, enabling resource discovery via APIs, improving visibility and understanding of Kubernetes environments without requiring an agent within the cluster. This feature also integrates identity binding, linking Kubernetes resources to Azure identities, strengthening overall cloud security posture.
Agentless Scanning for VMs Agentless scanning for virtual machines enables vulnerability identification without the need to install additional agents. It generates a software inventory and scans for secrets like SAS Tokens and SSH keys, enhancing the efficiency and accuracy of security checks. This functionality is especially useful for IaaS virtual machines where installing agents is not possible or desirable. It supports VM scanning across major cloud providers (Azure, AWS, GCP).
Data-Aware Security Posture The data-aware security posture feature provides automatic discovery and assessment of data sensitivity and exposure. Using intelligent sampling methods, it identifies data-related risks and offers continuous risk discovery, generating alerts for suspicious activity and strengthening overall data security. It also includes automatic detection of sensitive data (PII, financial information, credentials) and automatic classification based on predefined policies.

By correlating the insights generated by these agentless capabilities, organizations can gain a deeper understanding of their security profile. It's a synergistic approach that can provide a solid foundation for building a proactive cloud security strategy.

Let's explore how these elements work together within your security infrastructure.

Contextualized cloud posture management

Agentless capabilities can significantly improve Cloud Posture Management (CPM) by offering a more contextualized and comprehensive understanding of the cloud environment.

For example, the vulnerability assessment functionality of the Azure container registry provides information on potential security weaknesses in containerized applications, allowing CPM to prioritize and address risks based on severity and potential impact.

By automating asset discovery and continuous monitoring, these capabilities help maintain an up-to-date asset inventory, which complements CPM's role in providing accurate and timely visibility into the cloud's security posture.

Analysis of attack paths

Attack path analysis is another area that benefits significantly from the insights generated by agentless capabilities. By discovering VM vulnerabilities and potential attack vectors, these capabilities facilitate a more targeted and effective analysis.

For example, agentless VM vulnerability assessment provides information about possible attack paths that an adversary could exploit. This data can then be used to prioritize remediation actions based on the potential impact on the environment, effectively reducing attack paths and minimizing the risk of a successful breach.

Security risk analysis

By taking advantage of agentless capabilities, security risk analysis can be even more proactive and comprehensive. Real-time detection of potential threats, whether related to data sensitivity or container vulnerabilities, allows security teams to quickly identify and mitigate risks.

In addition, Discovery features for Kubernetes can provide useful information about configuring Kubernetes environments, further helping to identify security risks associated with misconfigurations or obsolete components.

Conclusions

Companies that operate in the cloud today find themselves having to face challenges regarding the security of their data that, even at the beginning of the century, would have been considered an exaggeration in the corporate cybersecurity sector.

Yet we have arrived at this point, with a monstrous increase in cyber threats and the risks associated with them that can no longer be ignored and for which every self-respecting business should take appropriate countermeasures.

Defender for Cloud and the Defender CSPM plan are positioned in this scenario as incredibly solid solutions to adopt for any company that operates within Microsoft, hybrid cloud and multi-cloud environments, in order to give their teams of experts the tools necessary to set up the best defenses for their digital infrastructures “in the clouds” with only a minimum additional cost.

So all we have to do is invite anyone interested to get a first taste of the basic CSPM functionality of Defender for Cloud and evaluate the transition to the Defender CSPM plan once they understand the needs related to their security posture.
