DQ and data governance are reactive processes; however, with recent advancements in artificial intelligence (AI), a proactive process can be developed for early detection and remediation of these DQ and data governance issues. Let’s break down the key aspects of this approach:

  • Automated configuration monitoring: A CSPM tool leveraged with AI-enhanced anomaly detection algorithms can continuously monitor cloud configurations, looking for anomalies or deviations from established security and governance policies. By understanding normal configuration patterns, AI can quickly identify potential issues. AI can be programmed to perform DQ checks directly within cloud configurations, ensuring that data storage, access controls, and encryption settings align with governance and quality standards.
  • Continuous compliance monitoring: AI-driven policy enforcement can assist in enforcing data governance policies by continuously monitoring cloud resources for compliance with industry standards and regulations. This proactive approach helps identify non-compliant configurations that may impact DQ. AI algorithms can analyze configurations and access patterns to identify potential governance violations, such as unauthorized access or data usage, triggering alerts for prompt remediation at a very early stage proactively.
  • Threat detection and IR: AI-powered behavioral analytics can be employed to analyze user and entity behavior within the cloud environment. This helps in the early detection of suspicious activities that may pose threats to both security and DQ. AI can be integrated into IR mechanisms to align with data governance policies, ensuring a coordinated approach to addressing security incidents that may impact data integrity.
  • Vulnerability management: AI can analyze data from vulnerability scanners and other security tools to identify potential vulnerabilities in cloud infrastructure. This proactive identification allows organizations to remediate vulnerabilities before they can be exploited. AI can assess the potential impact of vulnerabilities on DQ, helping prioritize remediation efforts based on the criticality of the affected data.
  • Automated IR: Develop IR playbooks with AI-driven automation to expedite the remediation of security incidents. This ensures a rapid and consistent response to incidents that may have implications for DQ and governance.
  • Collaboration with data governance: Integrate AI-driven CSPM with data governance processes to create a unified strategy. This involves aligning security policies with data governance requirements to ensure comprehensive protection for both security and DQ. AI can facilitate cross-domain analysis, assessing how changes in security configurations may impact DQ and governance, providing a holistic view of the potential risks and their remediation.

Leveraging AI for CSPM to build a proactive DQ and data governance process involves incorporating AI capabilities into security practices to detect and remediate issues that may impact the integrity, availability, and compliance of data stored in the cloud. This integrated approach can ensure a robust and proactive stance toward managing both security and data governance in cloud environments. Let us now dive deep into the best practices involved in overcoming integration challenges.

Setting up effective reporting in a CSPM tool involves careful planning and configuration to ensure that the reports generated provide valuable insights into your cloud security posture. Here is a general guide to help you set up the reporting environment as per industry best practices:

  • Identify reporting requirements: Clearly define the objectives of your reporting. Identify key stakeholders who will be consuming the reports and understand their specific requirements. Determine the frequency, scope, and depth of the reports based on these requirements.

For example, determine reporting requirements for compliance. It is crucial to understand the compliance frameworks or regulations applicable to your organization.

  • Identify relevant metrics: Identify key metrics and security controls that are critical to monitor and report on. These metrics can include factors such as misconfigurations, compliance violations, access controls, network security, data encryption, and more.

For example, ensure that the selected metrics align with your organization’s security policies, compliance frameworks, and industry best practices.

  • Select report types: Determine the types of reports you need to generate. In addition to compliance reports, you may also require vulnerability reports, risk assessment reports, asset inventory reports, or any other reports relevant to your CSM objectives; for example, management reports about the overall improvement of the vulnerability posture over time.
  • Define report templates: Create or customize report templates that align with your reporting requirements. These templates should include sections and placeholders for the required data, metrics, visualizations, and any compliance-related information.
  • Identify data sources: Identify data sources that provide the necessary information for generating reports. This includes integration with CSP APIs, CMDBs, vulnerability assessment tools, or other relevant systems that capture the required data for the reports.
  • Configure data collection: Configure the CSPM tool to collect the relevant data for report generation. Specify the data collection settings, such as the frequency of data collection, specific metrics, or events to be captured, and any filters or criteria to apply during data collection.
  • Data processing and analysis: Once the data is collected, the CSPM tool processes and analyzes it to generate insights, compliance status, and other relevant information. This involves applying compliance frameworks, risk algorithms, or custom rulesets to assess the security posture and compliance levels.
  • Report generation and customization: Utilize report templates and processed data to generate reports. The CSPM tool should provide functionality or reporting modules to customize reports based on your specific requirements. Customize data visualizations, including summary statistics, graphs, tables, and charts, and ensure the report layout meets your needs.
  • Schedule report generation: Set up a schedule for automatic report generation based on the desired frequency (for example, daily, weekly, or monthly). Configure the CSPM tool to generate compliance reports and other reports at specified intervals.
  • Distribution and delivery: Determine recipients or stakeholders who should receive the reports. Configure the CSPM tool to automatically distribute generated reports to the designated recipients via email, file-sharing platforms, or other delivery methods. Ensure proper access controls and encryption measures are in place to protect the confidentiality and integrity of reports during transmission. You can also consider building a unified dashboard for different stakeholders using tools such as Microsoft Power BI or Grafana.
  • Monitoring and maintenance: Regularly monitor the reporting environment to ensure that reports are generated correctly, data sources are up to date, and delivery mechanisms are functioning properly. Perform periodic checks and updates to report templates, data collection settings, and distribution settings as needed.
  • Continuous improvement and feedback: It is important to seek feedback from report recipients to understand their needs and preferences. Continuously improve the reporting process by incorporating feedback, refining report templates, and enhancing data analysis techniques.

You can overcome challenges and establish an effective reporting environment within the CSPM tool. This enables informed decision-making, improved compliance monitoring, and enhanced visibility into the security posture of the cloud environment. Let us now understand another component of environment settings, which is activity logging.

Managing users, groups, and API permissions in CSPM tools comes with several challenges and requires adherence to best practices to ensure effective access control and security. Let us look at some usual challenges in permissions management in CSPM tools:

  • Complexity and scale: CSPM tools often deal with complex and dynamic cloud environments, involving multiple cloud platforms, numerous resources, and many users. Managing users and their permissions across such a dynamic landscape can become challenging, especially when considering frequent changes, onboarding/offboarding users, and evolving cloud resources.
  • Role and permission creep: This refers to the gradual accumulation of excessive privileges or permissions assigned to user roles over time. This occurs when users accumulate excessive privileges or are granted permissions beyond what is necessary for their role, leading to increased security risks and potential misuse of privileges.
  • Granularity and fine-grained access control: CSPM tools may require fine-grained access control to ensure that users have appropriate access to specific features, resources, or data. Implementing and managing granular access control can be challenging, as it requires a careful balance between granting sufficient access for users to perform their tasks while limiting unnecessary privileges.

Best practices to overcome permission-related challenges

Organizations can effectively manage permissions in CSPM tools, reduce security risks, maintain compliance, and ensure the integrity of their cloud security posture. Let us understand the best practices to overcome the challenges discussed previously:

  • Centralized IAM: Integrate CSPM tools with centralized IAM systems to leverage existing user directories and authentication mechanisms. Centralized IAM provides a single source of truth (SSOT) for user management and simplifies access control across multiple systems and applications.
  • PoLP: Adhering to PoLP is crucial in CSPM user management. Users should be granted the minimum privileges necessary to perform their specific tasks, reducing the risk of unauthorized access or misuse of privileges. Regular reviews of user permissions should be conducted to ensure permissions align with job responsibilities.
  • Role-based access control (RBAC): Implement RBAC to simplify and streamline user management. Define roles based on job functions, responsibilities, and access requirements. Assign users to appropriate roles rather than individually assigning permissions. This allows for easier administration, scalability, and consistent access control across the organization.
  • Standardize attributes and use attribute-based access control (ABAC): Standardize attributes to ensure consistency across your cloud environment. This simplifies the management of permissions and reduces the potential for misconfiguration. ABAC enables precise, context-aware access decisions, reducing over-privileging and the risk of unauthorized access. It provides a more precise and versatile alternative to traditional access control models such as RBAC.
  • Utilize tag-based access control (TBAC): Utilize tags and TBAC effectively because it provides a dynamic and fine-grained approach to access control in complex and dynamic environments.
  • Regular access reviews and audits: Conduct periodic reviews and audits of user accounts and permissions to ensure they remain accurate, up to date, and aligned with organizational requirements. Review user access privileges, remove unnecessary access, and identify any anomalies or deviations from established access controls.
  • Segregation of duties (SoD): Implement SoD to prevent conflicts of interest and reduce the risk of fraudulent activities. Ensure that critical tasks, such as configuration changes or approving access requests, require multiple individuals with distinct roles and responsibilities to prevent single points of failure (SPOFs) or potential security breaches.
  • Streamlined user onboarding and offboarding processes: Establish well-defined processes for user onboarding and offboarding. This includes ensuring proper user provisioning and deprovisioning procedures, including the creation, modification, or deletion of user accounts and associated permissions. Promptly remove access for users who leave the organization or change roles to prevent unauthorized access.
  • Training and awareness: Provide training and awareness programs to educate users about the importance of security, appropriate use of privileges, and adherence to organizational security policies. Users should be aware of their responsibilities, the potential risks of inappropriate access or actions, and the importance of reporting any security concerns.
  • Regular backup and disaster recovery (DR): Implement regular backups of user and permission configurations within the CSPM tool. This ensures that user management settings can be restored in case of accidental deletion, system failure, or other unforeseen circumstances.

User group management is a process of organizing and managing users into coherent groups or roles within a CSPM tool. Grouping users provides organizations with a streamlined approach to access management (AM) and the ability to collectively assign permissions. Administrators can create groups, allocate users to these groups, and manage group membership. This simplifies administration by enabling permissions to be granted to the entire group, eliminating the need to individually assign permissions to each user. You can use groups to give multiple users a single set of permissions. This is the preferred method for assigning the same uniform permissions to many users. Making a user group consists of the following:

  1. Creating a new group: The group acts as a container for adding users with a single set of permissions.
  2. Setting group permissions: Choose what permissions you would like the group to have.
  3. Adding users to the group: When users are added to the group, they will all receive the same permissions and account accesses.

Most CSPM tools are already equipped with built-in user roles that serve the distinct set of permissions that an organization mostly uses to function. Let us look at some built-in roles.

Built-in user roles

As with any other Software-as-a-Service (SaaS) tools, built-in user roles in CSPM are predefined roles that come with the tool’s default configuration. These roles are designed to provide distinct levels of access and permissions to users based on their responsibilities and tasks within the CSPM environment. Next are common built-in user roles you may find in CSPM tools:

  • Super-admin/administrator/owner: The administrator or owner role typically has the highest level of access and control over the CSPM tool. Administrators have complete administrative privileges, allowing them to configure settings, manage user accounts, define permissions, and access all features and functionalities of the tool. They have the authority to make changes, create and modify policies, and oversee the overall operation of the CSPM tool.
  • Auditor/viewer/read-only: The auditor, viewer, or read-only role is for users who need read access to the CSPM tool without making any modifications. Users with this role can view security findings, reports, dashboards, and other relevant information but do not have the authority to change settings, configure policies, or modify user permissions. This role is suitable for stakeholders who need visibility into the security posture and compliance status of the cloud environment.
  • Security analyst/operator: Security analysts or operators play an active role in investigating security findings, triaging alerts, and taking appropriate actions within the CSPM tool. They have permissions to interact with security data, manage remediation workflows, communicate with other team members, and access specific features related to security analysis and incident response (IR). However, they may not have administrative capabilities or access to sensitive configuration settings.
  • Compliance manager: Compliance managers have specialized roles focused on ensuring adherence to regulatory requirements and internal policies. They have access to compliance-related features within the CSPM tool, such as defining compliance rules, benchmarks, and requirements. Compliance managers can generate compliance reports, track the organization’s compliance posture, and oversee remediation activities related to compliance violations.
  • Cloud account/resource owner: Some CSPM tools offer roles specific to individual cloud accounts or resource owners. These roles provide users with permissions to view and manage security findings, configurations, and compliance posture for their owned cloud resources. Resource owners can monitor and take actions related to the security of their specific cloud accounts or resources while maintaining segregation from other areas of the organization. For example, in the Orca CSPM tool, you can group the onboarded cloud accounts into business units (BUs) and provision access to the responsible team.
  • Custom roles: Custom roles and additional permissions are also offered by every CSPM tool to cater to specific requirements or to provide more granular access control within the tool.

These built-in user roles provide a foundation for managing access and permissions in CSPM tools. They offer predefined levels of access and authority, aligning with common organizational roles and responsibilities. However, it is important to note that the specific user roles available may vary depending on the CSPM tool. Organizations can assign these built-in user roles based on the user’s responsibilities and the principle of least privilege (PoLP), ensuring that users have the necessary access required to perform their tasks while minimizing the risk of unauthorized actions or data breaches.

Let us now understand another important topic: managing API tokens.

Environment settings typically refer to configurations and parameters that are specific to the environment in which the CSPM tool is deployed. This allows you to customize the CSPM tool to fit the specific requirements and characteristics of your cloud environment. Every organization’s cloud setup is unique, and these settings enable you to adapt the tool to your infrastructure, compliance standards, and security policies. Also, every CSPM tool is different, and hence no one explanation fits for every tool.

Note

There are dozens of CSPM tools on the market; for example, Prisma Cloud by Palo Alto Networks, Wiz, Orca, Microsoft Defender for Cloud, Amazon Web Services (AWS) Security Hub, Google Cloud Security Command Center, and Dome9, to name a few. Some of them are discussed in Chapter 3 at a very high level. Every tool comes with a distinct set of integration features and different ways of communicating with cloud environments and other tools. Some of the most critical aspects associated with setting up or fine-tuning CSPM tools are discussed in a generic manner without going into many details about a particular CSPM tool, deliberately.

Let us explore the various aspects of environment settings:

  • Cloud provider-specific settings: These settings are specific to the cloud provider you are using, and they configure how the CSPM tool interacts with and retrieves information from your cloud environment. For example, to connect to your AWS environment, you would need to configure the CSPM tool with AWS access keys or identity and access management (IAM) roles.
  • Compliance standards: CSPM tools often allow you to specify the compliance standards or frameworks that your organization needs to adhere to, such as the Center for Internet Security (CIS) benchmarks, the National Institute of Standards and Technology (NIST), the Health Insurance Portability and Accountability Act (HIPAA), or the General Data Protection Regulation (GDPR). For example, you can set your CSPM tool to check for the CIS AWS Foundations Benchmark or Payment Card Industry Data Security Standard (PCI DSS) compliance and configure the desired compliance level.
  • Notification and alerting settings: You can configure how the CSPM tool notifies you about security issues or policy violations. This includes email notifications, integrations with incident management (IM) tools, or other alerting mechanisms. For example, you can specify which email addresses or IM systems should receive notifications when a security issue is detected.
  • Scanning schedule: You can define/customize how often the CSPM tool should scan your cloud environment for security issues. This involves setting up regular scans, immediate scans after specific events, or custom schedules based on your organization’s requirements; for example, daily scans during off-peak hours or real-time scans triggered by specific cloud events.
  • Policy definitions: You can define and customize security policies or rules that the CSPM tool should enforce in your environment. These policies cover aspects such as proper data encryption, access control, network configurations, and more. For example, you can create custom policies to ensure that your resources are configured in alignment with your organization’s specific security requirements.
  • Remediation actions: CSPM tools often include automated remediation capabilities, allowing you to specify actions to be taken automatically when a security violation is detected. For example, the tool might automatically close a security group rule that is deemed too permissive or set up automated actions, such as closing unused security groups or rotating access keys, when violations are found.

Environment settings in a CSPM tool allow you to tailor the tool’s behavior to your specific cloud environment and security needs, ensuring that it effectively monitors, reports, and helps remediate security issues in your cloud infrastructure. Let us now explore those key aspects one by one, starting with user access management (UAM).

Cost management in cloud environments is crucial to optimizing expenditure and ensuring efficient resource allocation. TBAC can play a vital role in controlling costs by allowing organizations to categorize and manage resources based on their attributes. By tagging resources with attributes such as department, project, or environment, it becomes easier to track costs associated with each category. This enables more accurate showback and chargeback practices, where the costs of cloud resources are transparently attributed to specific departments or teams. Showback allows you to provide insights to various stakeholders on their resource consumption, while chargeback enables you to bill the respective departments or teams for their resource usage. Implementing TBAC alongside showback and chargeback concepts ensures that cost management is both effective and transparent, facilitating better decision-making and cost optimization.

Regular access reviews, adherence to PoLP, and robust processes for user life cycle management are essential for maintaining a secure and well-managed CSPM environment. Let us now understand another important aspect of environment setting, which is the integration of CSPM tools with other tools.

CSPM integrations with other tools

Most CSPM tools offer integration with other tools to improve overall security management processes. Integration is nothing but the process of connecting and combining the functionalities of different software tools or systems to achieve enhanced functionality, streamlined workflows, and improved data exchange. Integration allows tools to work together seamlessly, leveraging each other’s capabilities and data to create a more comprehensive and efficient solution.

Tool integration provides several benefits, including the following:

  • Streamlined workflows: Integration reduces manual effort, improves data accuracy, and streamlines processes by enabling data and actions to flow seamlessly between tools. This enhances productivity and reduces the potential for errors.
  • Enhanced functionality: By combining the capabilities of different tools, integration extends the functionality and effectiveness of each individual tool. This allows organizations to leverage the strengths of multiple tools and create a more comprehensive solution.
  • Data synchronization: Integration ensures that data remains consistent and up to date across different systems. For example, integrating a CSPM tool with a configuration management database (CMDB) ensures that security assessments are based on the most accurate and recent configuration data.
  • Automation and efficiency: Integration enables automated workflows and actions triggered by events or conditions in one tool. This reduces manual intervention, improves response times, and increases overall operational efficiency.

Microsoft Defender for Containers is a cloud-based solution designed to safeguard your containerized environments. It protects your clusters whether they’re running in Azure Kubernetes Service (AKS), Amazon Elastic Kubernetes Service (EKS) in a connected Amazon Web Services (AWS) account, Google Kubernetes Engine (GKE) in a connected Google Cloud Platform (GCP) project, or other Kubernetes distributions (using Azure Arc-enabled Kubernetes). Defender for Containers brings with it the three core aspects of container security, which are as follows:

  • Environment hardening: As stated previously, Defender for Containers safeguards your Kubernetes clusters regardless of whether they are operating on Azure Kubernetes Service, on-premises or infrastructure as a service (IaaS) Kubernetes, or Amazon EKS. Container Sentry offers ongoing assessments of clusters, delivering enhanced visibility into misconfigurations and supported with actionable guidelines to mitigate identified threats.
  • Vulnerability assessment: It also supplies vulnerability assessment for images stored in Azure Container Registry and Elastic Container Registry (ECR).
  • Runtime nodes and clusters protection: Alerts are generated by the threat protection system for both clusters and nodes, signaling potential threats and suspicious activities.

Let us now understand the Defender for Containers architecture diagram.

Defender for Containers architecture diagram

Defender for Containers is developed differently for each Kubernetes environment. The links in this section give you the detailed and updated architecture diagram for each Kubernetes environment.

Azure Kubernetes Service (AKS)

When safeguarding a cluster hosted in AKS, Defender for Cloud ensures a seamless and effortless process for collecting audit log data without the need for an agent. The deployment of the Defender profile on each node enables runtime protections and helps the collection of signals. For more comprehensive information, please consult the Microsoft documentation (https://learn.microsoft.com/en-us/azure/defender-for-cloud/defender-for-containers-architecture?tabs=defender-for-container-arch-aks#architecture-diagram-of-defender-for-cloud-and-aks-clusters).

Figure 7.1 – Architecture diagram of Defender for Cloud and AKS cluster (source: Microsoft)

Arc-enabled Kubernetes clusters

When a non-Azure container is integrated with Azure through Arc, the Arc extension collects Kubernetes audit logs from every control plane node within the cluster. Subsequently, the extension transmits the log data to the Microsoft Defender for Cloud backend in the cloud, enabling comprehensive analysis. Although the extension is associated with a Log Analytics workspace used as a data pipeline, the audit log data itself is not stored within the Log Analytics workspace.

For more details and updated information on this, refer to your chosen CSPM vendor documentation or, in this case, the Microsoft documentation (https://learn.microsoft.com/en-us/azure/defender-for-cloud/defender-for-containers-architecture?tabs=defender-for-container-arch-eks#architecture-diagram-of-defender-for-cloud-and-eks-clusters).
