Key challenges in permission management – Exploring Environment Settings

October 30th, 2023

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 – Exploring Environment Settings

September 19th, 2023

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:

Creating a new group: The group acts as a container for adding users with a single set of permissions.
Setting group permissions: Choose what permissions you would like the group to have.
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 overview – Exploring Environment Settings

August 24th, 2023

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).

Managing users and permissions – Exploring Environment Settings

April 8th, 2023

A user is a member of your organization whom you would like to grant access to your CSPM tool. Usually, you can invite a user from the CSPM tool with specific permissions to define the scope of their activities and create groups consisting of multiple users with a single set of permissions, and you can also create custom roles defining specific user permissions. User and group permissions settings refer to the configuration and management of user accounts, groups, and their associated access permissions within the CSPM environment. These settings play a crucial role in maintaining a secure and well-controlled access control framework. Let us now understand how user management works in most CSPM tools.

User management

User management involves the management of individual user accounts within the CSPM environment. This includes creating user accounts, assigning unique identifiers (such as usernames or email addresses), and defining authentication mechanisms (for example, passwords or multi-factor authentication (MFA)). Managing users’ permissions in CSPM tools involves configuring and controlling access to the tool’s functionalities and resources. Let us look at the process involved in managing users’ permissions in CSPM tools:

User account creation: The first step in managing users is creating user accounts within the CSPM tool. This typically involves providing necessary details such as usernames, email addresses, and authentication credentials. CSPM tools also integrate with existing identity management systems, allowing administrators to synchronize user accounts or authenticate users through SSO mechanisms.
Role assignment: After user accounts are created, roles are assigned to determine the level of access and permissions for each user. Roles typically correspond to predefined sets of permissions within the CSPM tool. Common roles include super-admins, administrators, viewers, security analysts, compliance managers, and resource owners. The selection of roles depends on the tool’s capabilities and the organization’s requirements.
Permission configuration: Once roles are assigned to users, administrators configure permissions associated with each role. Permissions define the actions and operations a user can perform within the CSPM tool. This includes accessing specific features, viewing security findings, generating reports, modifying settings, and managing resources. Permission configuration ensures that users have appropriate access levels based on their responsibilities and requirements.
Access control management (ACM): Managing access control involves defining rules and policies to control user access to the CSPM tool and its resources. This includes configuring MFA requirements, password policies, and session timeouts. Access control settings help ensure secure user authentication and prevent unauthorized access to sensitive information within the CSPM tool.
User life cycle management: Over time, the user landscape may change within an organization. Managing users also includes handling tasks such as user onboarding, offboarding, and role changes. When a user joins a security team, and their responsibility includes working on the CSPM tool, their account is created and assigned appropriate roles and permissions. When a user leaves or moves to another department, their account is disabled or removed to prevent unauthorized access. Role changes may also occur as users’ responsibilities evolve, requiring adjustments to their permissions.
Auditing and monitoring: CSPM tools often provide auditing and monitoring capabilities to track user activities and permission changes. Auditing logs can help identify any suspicious or unauthorized actions within the tool. Regular monitoring of user accounts and permissions helps maintain the integrity and security of the CSPM environment.
Regular access reviews and updates: It is important to conduct periodic access reviews of user accounts and permissions to ensure they remain aligned with the organization’s evolving needs and security requirements. This includes removing unnecessary access, adjusting permissions based on role changes, and identifying potential security gaps or excessive privileges.

Managing users’ permissions in CSPM tools is a crucial aspect of maintaining an effective and secure cloud security posture. Let us understand how user group management works.

Managing API tokens – Exploring Environment Settings

March 31st, 2023

Managing API tokens involves the administration and control of access tokens used to authenticate and authorize API-based interactions between the CSPM tool and cloud service providers (CSPs) or other external systems. API tokens serve as credentials to establish secure communication and enable the tool to gather security-related information, analyze cloud configurations, and assess the security posture of the cloud environment.

Let us understand how managing API tokens works in most CSPM tools:

Token generation and configuration: In CSPM, you can generate more than one API token and use them for different purposes. For example, you can create API tokens that are used in different automations to request different data from the CSPM tool. After generating API tokens, administrators define access control policies and permissions associated with each token. This determines the level of access the CSPM tool has to various cloud resources and services. Access control ensures that the tool only accesses the necessary information and resources required for security assessments and monitoring.
Token usage: Once you have configured the API token, you can use it for integration with other applications. You can make requests from your application to the CSPM tool API to receive data on alerts, assets, vulnerabilities, and other objects. The API tokens can be used in CSPM automations. When you create an automation, you can select the API token created for your application in the tool integrations; for example, with the integration of the CSPM tool with the security information and event management (SIEM)/security orchestration, automation and response (SOAR) section.
Token life cycle management: Managing API tokens involves handling their life cycle, including creation, rotation, and revocation. Periodic token rotation is recommended as a security best practice to minimize the risk of compromised tokens. When a token is no longer needed or if there are concerns about its security, administrators should promptly revoke or disable the token to prevent unauthorized access.
Secure storage: API tokens should be stored securely within the CSPM tool’s infrastructure. Proper measures such as encryption and access controls should be implemented to protect tokens from unauthorized access or accidental exposure. Additionally, it is crucial to follow security best practices for securing the storage system that holds the tokens, such as strong access controls, monitoring, and auditing.
Token usage tracking and auditing: Administrators should track and audit the usage of API tokens within the CSPM tool. This helps identify any suspicious or unauthorized activities associated with tokens. By monitoring token usage, administrators can detect potential security incidents or misuse of privileges, enabling timely response and mitigation.
Integration with IAM: CSPM tools often integrate with IAM systems or cloud provider IAM services. This integration enables the seamless management and synchronization of API tokens with existing user accounts and access control policies. It ensures that the tokens align with the organization’s broader IAM framework and security policies.

Effective management of API tokens in CSPM tool management helps ensure secure and controlled access to cloud resources and enables accurate security assessments.

EFFECTIVE COST MANAGEMENT USING TBAC, SHOWBACKS, AND CHARGEBACKS – Exploring Environment Settings

February 25th, 2023

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.

Implementing tool integrations requires understanding APIs, protocols, or interfaces provided by the tools involved and configuring them to work together. Integration capabilities can vary depending on the tools and the availability of pre-built connectors or APIs for integration purposes.

Reporting and analytics integration – Exploring Environment Settings

February 13th, 2023

Integration with reporting and analytics platforms enables the CSPM tool to generate comprehensive security reports, visualizations, and insights. This integration allows security teams to analyze trends, track compliance status, and present the organization’s security posture to stakeholders effectively. Integration can be with Microsoft Power BI and Grafana, which are the most common tools used in the industry. Using a wide range of API offerings by CSPM tools, it becomes possible to integrate these with reporting. We will discuss reporting in detail in the next section of this chapter. Let us now understand CSPM tool integration with SIEM/SOAR tools.

Monitoring (SIEM/SOAR) tool integration

Integrating SIEM and SOAR tools with CSPM solutions is a crucial part of monitoring the security of cloud infrastructure. This integration helps you centralize and automate security monitoring, incident detection, and response in your cloud environment. Let’s take a closer look at this:

SIEM integration: Integration between a CSPM tool and an SIEM system allows the exchange of security-related data and events. CSPM tools can feed security findings, alerts, and configuration data to the SIEM system, enriching overall security event monitoring and analysis. SIEM integration provides a broader context to CSPM data, enabling correlation with other security events across the infrastructure and enhancing threat detection capabilities.
SOAR integration: CSPM tools can integrate with SOAR platforms to automate IR workflows. By exchanging data and alerts between the CSPM tool and the SOAR platform, security teams can automate response actions based on predefined playbooks or workflows. This integration streamlines IR, enables the rapid containment and remediation of security incidents, and enhances overall operational efficiency.

Using CSPM data in your applications is a key reason for configuring integration with the CSPM tool. Once the CSPM tool is integrated with your application, you can receive data from it, including data on alerts, assets, and other objects. This data can be utilized for diverse purposes such as in-depth analysis, storage, ticket creation, and more.

You can integrate your application with CSPM tools using the API and Webhooks:

Using API integration: The API functionality of the CSPM tool enables you to retrieve data and perform actions within the tool, such as initiating asset scans or verifying alerts. To utilize the API, you need to set up an API token within the tool. Once the API token is configured, you can send API requests from your application to interact with the CSPM tool, accessing the desired data or triggering specific actions.
Using Webhook integration: Webhooks enable the real-time pushing of alert data from the CSPM tool to your system as soon as specific alerts are identified. By incorporating Webhooks into notification integrations, you can promptly send messages or emails when critical alerts are detected, requiring immediate response actions. This ensures timely awareness and enables swift IM.

An effective CSPM tool should be able to integrate with a commonly used and wide range of SIEM/SOAR tools such as Splunk, Microsoft Sentinel, Sumo Logic, IBM QRadar, Cribl, JupiterOne, Vulcan, Chronicle, Swimlane, and more.
