Summary

Setting the CSPM environment is a crucial procedure for tools as it establishes the foundation for effective CSM. In this chapter, we delved into crucial topics such as user management, permissions settings, integrations with other tools, reporting capabilities, challenges, and best practices to overcome challenges. In the next chapter, we will deep dive into cloud asset inventory.

Activity logging – Exploring Environment Settings

July 23rd, 2024

Activity logging refers to the process of recording and tracking activities and events within the CSPM environment. It involves capturing relevant information about user actions, system activities, and security events to maintain an audit trail for monitoring, analysis, and compliance purposes. These activities also include changes to configurations, user access and permissions, network traffic, system events, and more. The purpose of activity logging is to provide a comprehensive audit trail and visibility into actions and behaviors within the cloud infrastructure, helping organizations monitor, detect, and respond to security threats and compliance issues. Let us now understand the key elements associated with activity logging.

User activities

Activity logging records user actions within the CSPM tool, such as user logins, changes to user permissions, configuration modifications, and execution of various operations or tasks. These actions include the following:

User authentication and authorization: Logging user logins, successful and failed authentication attempts, and authorization decisions (for example, granting or revoking user access)
Resource provisioning and management: Tracking actions such as creating, modifying, or deleting cloud resources such as VMs, databases, storage buckets, network configurations, and so on
Configuration changes: Recording modifications made to the configuration settings of cloud services, such as firewall rules, access controls, encryption settings, or any other parameters that affect security and compliance
Data access and manipulation: Logging when users access or modify data stored within the cloud environment, including reading, writing, or deleting files, databases, or other sensitive information
Account and identity management: Tracking changes related to user accounts, such as user creation and deletion, password resets, or changes to user roles and permissions such as privilege escalation

Vendor access to customer CSPM environment – benefits, risks, and best practices

Benefits: It is quite common for vendor-side engineers to have access to your CSPM environment in the deployment phase. Usually, vendors provide support for the smooth deployment of the tool, and it is quite beneficial and time-saving for customers. Sometimes, it is also beneficial to extend permissions to the vendor side when a customer needs help with investigations into abnormal behavior of tools or with some exceptional cases. These situations continue to grow and are not rare.

Risks: Having vendor access to your environment introduces risks such as exposure to security loopholes, data infiltrations, data theft, and more. Organizations need to be aware of these situations and should introduce certain measures to mitigate those risks.

Best practices: The first and most important action is to have a non-disclosure agreement (NDA) signed by the vendor that is legally binding and establishes a confidential relationship. This makes the vendor agree that sensitive information they may obtain will not be made available to others. There must not be default and forever access to the vendor. If needed, the CSPM admin should provide time-bound access to the tool and must revoke access as soon as the support task is completed. During this period, a complete activities log must be tracked, stored, and reviewed. It is also important to understand that most CSPM tools are offered as SaaS versions, and hence as a CSPM customer, you do not have visibility of the inline infrastructure of the tool. However, on the application front, the customer must have complete visibility and control of the user’s activities.

It is the CSPM vendor’s responsibility to maintain and secure online infrastructure such as system activities. Based on mutual agreement or for transparency, vendors can and should share the high-level penetration testing report or System and Organizations Controls 2 (SOC 2)-type report of their infrastructure. However, read on to understand the full context.

Let’s look at this in more detail:

System startup and shutdown: Recording when cloud services, VMs, or containers start or stop running
Resource allocation and deallocation: Logging events related to the allocation and deallocation of computing resources, such as VM instances, storage volumes, or network resources
Network traffic and communication: Capturing network-related activities, including incoming and outgoing traffic, communication between different cloud resources, and network security events such as port scanning or suspicious network connections
Performance monitoring: Tracking system performance metrics such as CPU utilization, memory usage, disk I/O, or network latency to identify potential bottlenecks, resource constraints, or anomalies

Security events

Security events represent activities or incidents that have potential security implications or indicate a breach or violation. It also monitors and logs security-related events and incidents, such as policy violations, unauthorized access attempts, potential breaches, or changes to security configurations. Let’s look at some examples:

Intrusion attempts: Logging activities such as failed login attempts, brute-force attacks, or unauthorized access attempts to systems or applications
Malware or virus detection: Recording events related to the detection or quarantine of malware, viruses, or other malicious software within the cloud environment
Security policy violations: Capturing events that indicate violations of security policies, such as attempts to bypass security controls, unauthorized changes to configurations, or non-compliance with regulatory requirements
Anomalies and suspicious behavior: Logging activities that deviate from normal patterns or behavior, such as unusual login times, repeated failed authentication attempts, or abnormal resource usage
Security IR: Documenting actions taken during IR, including alerts triggered, investigations conducted, containment measures implemented, and remediation steps performed

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.

IMPORTANT NOTE – Exploring Environment Settings

November 13th, 2023

It is important for organizations to make sure the various tools (SIEM, ticketing, SSO, and so on) used within the organization are also part of the tools offered by CSPM vendors. CSPM vendors also must provide comprehensive guidance and support for the integration type they offer.

Let us now understand the most common integrations offered by CSPM tools.

SSO integration

SSO integration enables users to access the CSPM tool using their existing login credentials from a central IM system. This integration eliminates the need for separate login credentials, simplifies user management, and improves the user experience. Most CSPM tools are leveraged to integrate with industry-wide identity providers (IDPs) such as Okta, OneLogin, Azure Active Directory (AAD), AWS, SSO, Google Workspace, JumpCloud, Auth0, Ping Identity, and more. CSPM vendors usually also provide generic integration features for SSO integrations that are not offered directly by them.

SSO integration is a crucial step for modern security concepts such as zero-trust architecture (ZTA). Let us now understand another important topic, which is CSPM integration with ticketing tools.

Ticketing system integration

Integration with a ticketing or IM system allows the CSPM tool to automatically generate tickets or incidents when security findings or alerts are detected. This integration streamlines IR processes, ensures proper tracking and resolution of security issues, and provides a centralized view of security events. An effective CSPM tool should be able to integrate with a commonly used and wide range of ticketing tools such as BMC Remedy and ServiceNow, and agile tools such as Jira and Azure DevOps.

Ticketing tool integration is a crucial step for the remediation of security issues such as misconfigurations in the cloud environment. Let us now understand the integration of CSPM tools with communications tools.

Collaboration and communication (notifications) integrations

Integration with collaboration and communication platforms, such as Slack or Microsoft Teams, allows the CSPM tool to send real-time notifications, alerts, or reports to designated channels or individuals. This integration ensures that stakeholders are promptly informed about security events and can collaborate effectively to address them. Some of the most common notification integrations offered by CSPM tools are Slack, Microsoft Teams, PagerDuty, Opsgenie, Google Cloud Platform (GCP) Publish/Subscribe (Pub/Sub), Amazon Simple Queue Service (Amazon SQS), and Amazon Simple Notification Service (Amazon SNS).

By leveraging Webhook integration, you can automate the transmission of alerts to external applications. This functionality is particularly useful in client-side object model (CSOM) automations, where alerts from the CSPM tool can be seamlessly pushed to your application when specific automation conditions are fulfilled. Typically, CSPM tools send alert data to a designated Webhook endpoint through a POST HTTP request in JSON format. Webhook integrations offer distinct advantages over API token-based integrations as they are event-driven, triggering actions as opposed to scheduled API requests.

The integration of CSPM tools with communications tools is a very important step for the remediation of severe security issues as it enables us to inform the right stakeholders at runtime. Let us now understand the integration of CSPM tools that enrich reporting capabilities.
