Let us now understand how to set up effective reporting in a CSPM tool.

Storage integrations – Exploring Environment Settings

December 30th, 2023

A CSPM tool can also be integrated with the storage systems of different CSPs to enable the transmission of security-related alerts and notifications. This integration enhances the overall monitoring and IR capabilities of the CSPM tool by extending the reach of alerting mechanisms to include the storage environment. When the storage systems are integrated with the CSPM tool, you can configure sending data of the regular alert and asset reports from the tool to these storage systems for easy and convenient storing, searching, and auditing:

Integrating with an Amazon Simple Storage Service (S3) bucket: Amazon S3 is a highly scalable and secure object storage solution provided by AWS. It offers reliable data availability and performance and the ability to store and retrieve data of any size. With Amazon S3, you can effectively organize your data and manage access control through S3 buckets. When integrating Amazon S3 buckets with a CSPM tool, you can configure the seamless transfer of regular alert and asset report data to the S3 buckets. This integration simplifies the auditing process by providing a convenient and centralized location for storing and accessing these reports.
Integrating with Azure blobs: Azure Blob Storage is a cloud-based object storage solution provided by Microsoft. It is designed to efficiently store large volumes of unstructured data. Access to the objects stored in Blob Storage is enabled through the HTTP/HTTPS protocols. When integrating Azure Blob Storage with a CSPM tool, you gain the ability to configure the transfer of regular alert and asset report data to Blob Storage. This integration allows for multiple configurations, enabling the sending of various reports to distinct storage containers within Azure Blob Storage.
Integrating with a GCP bucket: GCP buckets serve as fundamental containers for storing data in cloud storage. All data stored in the cloud storage environment must be organized within buckets. Buckets provide a means to organize and manage your data while controlling access to it. When integrating GCP buckets with your CSPM tool, you gain the ability to configure the transfer of regular alert and asset report data to GCP buckets. This integration enables the seamless and automated delivery of important reports to designated GCP buckets within your cloud storage environment.

Storage integration makes it possible to bring different sorts of logs into one bucket, and you can then decide to build cases based on requirements. Let us understand key integration challenges and the best practices to tackle them.

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.

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.

Understanding container security challenges – Onboarding Containers

October 10th, 2022

Security in containerized environments is of paramount importance due to the unique challenges posed by containerization. While containerization provides many benefits in terms of agility, scalability, and portability, it also introduces unique security challenges that need to be addressed.

Let us now look at common security risks and threats in containerized environments:

Isolation and vulnerability management: Containers rely on a shared host kernel, and if one container is compromised, it can potentially impact other containers and the underlying host. Therefore, ensuring strong isolation between containers and proactive vulnerability management is crucial to prevent lateral movement of threats and unauthorized access.
Container image security: Containers are built from images that contain the application and its dependencies. These images must be regularly scanned for vulnerabilities and validated to ensure they do not include any malicious or outdated components. Failure to secure container images can lead to the exploitation of known vulnerabilities and compromise the integrity of the entire containerized environment.
Runtime threats and monitoring: Monitoring container runtime is essential to detect and respond to security incidents in real time. It involves tracking container behavior, network traffic, and application activity to identify anomalies or malicious activities. Continuous monitoring helps in the timely detection of runtime threats, such as unauthorized access attempts, abnormal resource usage, or malicious code execution.
Compliance and regulatory requirements: Organizations working in regulated industries need to ensure their containerized environments comply with industry-specific security standards and regulatory frameworks. Failure to meet these requirements can lead to severe legal and financial consequences. Proper security measures, such as access controls, data encryption, and audit logs, must be implemented to maintain compliance.
Orchestration and configuration security: Container orchestration platforms such as Kubernetes introduce additional security considerations. Securing the orchestration layer, managing access controls, and enforcing secure configuration practices are vital to protecting the underlying infrastructure and preventing unauthorized access or manipulation of containers.
Complex networking: Containers are often dynamic, and their IP addresses may change frequently. Service discovery becomes challenging in a dynamic and distributed environment. Managing networking for containers can be complex, especially when dealing with multiple containers on different hosts that need to communicate with each other.
Resource overhead: Container orchestration tools, such as Kubernetes or Docker Swarm, introduce additional resource overhead to manage and coordinate container deployment, scaling, and load balancing. Running multiple containers on a host can lead to resource contention, such as container density requiring careful resource allocation to ensure optimal performance.
Monitoring: Monitoring containers poses challenges due to their ephemeral nature. Traditional monitoring tools may struggle to provide real-time insights into the state of containers. Containers require specific monitoring tools that understand container orchestration platforms and can track metrics such as container health, resource usage, and application performance.
Logging management and aggregation: Containerized applications generate a large volume of logs, and managing and analyzing these logs becomes challenging. Centralized log management solutions are crucial but can be complex to set up. Aggregating logs from multiple containers and services requires a comprehensive strategy to ensure that logs are accessible for debugging and auditing purposes.
Secure deployment pipelines: Security should be integrated into the entire container deployment pipeline. From the development stage to production deployment, each step should include security checks and measures to ensure that containers are free from vulnerabilities and adhere to security best practices. Implementing secure container registries, automated security testing, and secure image signing are critical aspects of a secure deployment pipeline.
Container escape and privilege escalation: Container escape vulnerabilities, though rare, have the potential to compromise the entire host system. Proper security measures, such as user namespace remapping, seccomp, and AppArmor, must be implemented to mitigate the risk of container escape and privilege escalation attacks.
