It provides more information regarding Netdata’s technical and -organizational security and privacy measures. - -We have given special attention to all aspects of Netdata, ensuring that everything throughout its operation is as -secure as possible. Netdata has been designed with security in mind. - -## Netdata's Security Principles - -### Security by Design - -Netdata, an open-source software widely installed across the globe, prioritizes security by design, showcasing our -commitment to safeguarding user data. The entire structure and internal architecture of the software is built to ensure -maximum security. We aim to provide a secure environment from the ground up, rather than as an afterthought. - -### Compliance with Open Source Security Foundation Best Practices - -Netdata is committed to adhering to the best practices laid out by the Open Source Security Foundation (OSSF). -Currently, the Netdata Agent follows the OSSF best practices at the passing level. Feel free to audit our approach to -the [OSSF guidelines](https://bestpractices.coreinfrastructure.org/en/projects/2231) - -Netdata Cloud boasts of comprehensive end-to-end automated testing, encompassing the UI, back-end, and agents, where -involved. In addition, the Netdata Agent uses an array of third-party services for static code analysis, static code -security analysis, and CI/CD integrations to ensure code quality on a per pull request basis. Tools like Github's -CodeQL, Github's Dependabot, our own unit tests, various types of linters, -and [Coverity](https://scan.coverity.com/projects/netdata-netdata?tab=overview) are utilized to this end. - -Moreover, each PR requires two code reviews from our senior engineers before being merged. We also maintain two -high-performance environments (a production-like kubernetes cluster and a highly demanding stress lab) for -stress-testing our entire solution. This robust pipeline ensures the delivery of high-quality software consistently. - -### Regular Third-Party Testing and Isolation - -While Netdata doesn't have a dedicated internal security team, the open-source Netdata Agent undergoes regular testing -by third parties. Any security reports received are addressed immediately. In contrast, Netdata Cloud operates in a -fully automated and isolated environment with Infrastructure as Code (IaC), ensuring no direct access to production -applications. Monitoring and reporting is also fully automated. - -### Security Vulnerability Response - -Netdata has a transparent and structured process for handling security vulnerabilities. We appreciate and value the -contributions of security researchers and users who report vulnerabilities to us. All reports are thoroughly -investigated, and any identified vulnerabilities trigger a Security Release Process. - -We aim to fully disclose any bugs as soon as a user mitigation is available, typically within a week of the report. In -case of security fixes, we promptly release a new version of the software. Users can subscribe to our releases on GitHub -to stay updated about all security incidents. More details about our vulnerability response process can be -found [here](https://github.com/netdata/netdata/security/policy). - -### Adherence to Open Source Security Foundation Best Practices - -In line with our commitment to security, we uphold the best practices as outlined by the Open Source Security -Foundation. This commitment reflects in every aspect of our operations, from the design phase to the release process, -ensuring the delivery of a secure and reliable product to our users. For more information -check [here](https://bestpractices.coreinfrastructure.org/en/projects/2231). - -## Netdata Agent Security - -### Security by Design - -Netdata Agent is designed with a security-first approach. Its structure ensures data safety by only exposing chart -metadata and metric values, not the raw data collected. This design principle allows Netdata to be used in environments -requiring the highest level of data isolation, such as PCI Level 1. Even though Netdata plugins connect to a user's -database server or read application log files to collect raw data, only the processed metrics are stored in Netdata -databases, sent to upstream Netdata servers, or archived to external time-series databases. - -### User Data Protection - -The Netdata Agent is programmed to safeguard user data. When collecting data, the raw data does not leave the host. All -plugins, even those running with escalated capabilities or privileges, perform a hard-coded data collection job. They do -not accept commands from Netdata, and the original application data collected do not leave the process they are -collected in, are not saved, and are not transferred to the Netdata daemon. For the “Functions” feature, the data -collection plugins offer Functions, and the user interface merely calls them back as defined by the data collector. The -Netdata Agent main process does not require any escalated capabilities or privileges from the operating system, and -neither do most of the data collecting plugins. - -### Communication and Data Encryption - -Data collection plugins communicate with the main Netdata process via ephemeral, in-memory, pipes that are inaccessible -to any other process. - -Streaming of metrics between Netdata agents requires an API key and can also be encrypted with TLS if the user -configures it. - -The Netdata agent's web API can also use TLS if configured. - -When Netdata agents are claimed to Netdata Cloud, the communication happens via MQTT over Web Sockets over TLS, and -public/private keys are used for authorizing access. These keys are exchanged during the claiming process (usually -during the provisioning of each agent). - -### Authentication - -Direct user access to the agent is not authenticated, considering that users should either use Netdata Cloud, or they -are already on the same LAN, or they have configured proper firewall policies. However, Netdata agents can be hidden -behind an authenticating web proxy if required. - -For other Netdata agents streaming metrics to an agent, authentication via API keys is required and TLS can be used if -configured. - -For Netdata Cloud accessing Netdata agents, public/private key cryptography is used and TLS is mandatory. - -### Security Vulnerability Response - -If a security vulnerability is found in the Netdata Agent, the Netdata team acknowledges and analyzes each report within -three working days, kicking off a Security Release Process. Any vulnerability information shared with the Netdata team -stays within the Netdata project and is not disseminated to other projects unless necessary for fixing the issue. The -reporter is kept updated as the security issue moves from triage to identified fix, to release planning. More -information can be found [here](https://github.com/netdata/netdata/security/policy). - -### Protection Against Common Security Threats - -The Netdata agent is resilient against common security threats such as DDoS attacks and SQL injections. For DDoS, -Netdata agent uses a fixed number of threads for processing requests, providing a cap on the resources that can be -consumed. It also automatically manages its memory to prevent overutilization. SQL injections are prevented as nothing -from the UI is passed back to the data collection plugins accessing databases. - -Additionally, the Netdata agent is running as a normal, unprivileged, operating system user (a few data collections -require escalated privileges, but these privileges are isolated to just them), every netdata process runs by default -with a nice priority to protect production applications in case the system is starving for CPU resources, and Netdata -agents are configured by default to be the first processes to be killed by the operating system in case the operating -system starves for memory resources (OS-OOM - Operating System Out Of Memory events). - -### User Customizable Security Settings - -Netdata provides users with the flexibility to customize agent security settings. Users can configure TLS across the -system, and the agent provides extensive access control lists on all its interfaces to limit access to its endpoints -based on IP. Additionally, users can configure the CPU and Memory priority of Netdata agents. - -## Netdata Cloud Security - -Netdata Cloud is designed with a security-first approach to ensure the highest level of protection for user data. When -using Netdata Cloud in environments that require compliance with standards like PCI DSS, SOC 2, or HIPAA, users can be -confident that all collected data is stored within their infrastructure. Data viewed on dashboards and alert -notifications travel over Netdata Cloud, but are not stored—instead, they're transformed in transit, aggregated from -multiple agents and parents (centralization points), to appear as one data source in the user's browser. - -### User Identification and Authorization - -Netdata Cloud requires only an email address to create an account and use the service. User identification and -authorization are conducted either via third-party integrations (Google, GitHub accounts) or through short-lived access -tokens sent to the user’s email account. Email addresses are stored securely in our production database on AWS and are -also used for product and marketing communications. Netdata Cloud does not store user credentials. - -### Data Storage and Transfer - -Although Netdata Cloud does not store metric data, it does keep some metadata for each node connected to user spaces. -This metadata includes the hostname, information from the `/api/v1/info` endpoint, metric metadata -from `/api/v1/contexts`, and alerts configurations from `/api/v1/alarms`. This data is securely stored in our production -database on AWS and copied to Google BigQuery for analytics purposes. - -All data visible on Netdata Cloud is transferred through the Agent-Cloud link (ACLK) mechanism, which securely connects -a Netdata Agent to Netdata Cloud. The ACLK is encrypted and safe, and is only established if the user connects/claims -their node. Data in transit between a user and Netdata Cloud is encrypted using TLS. - -### Data Retention and Erasure - -Netdata Cloud maintains backups of customer content for approximately 90 days following a deletion. Users have the -ability to access, retrieve, correct, and delete personal data stored in Netdata Cloud. In case a user is unable to -delete personal data via self-services functionality, Netdata will delete personal data upon the customer's written -request, in accordance with applicable data protection law. - -### Infrastructure and Authentication - -Netdata Cloud operates on an Infrastructure as Code (IaC) model. Its microservices environment is completely isolated, -and all changes occur through Terraform. At the edge of Netdata Cloud, there is a TLS termination and an Identity and -Access Management (IAM) service that validates JWT tokens included in request cookies. - -Netdata Cloud does not store user credentials. - -### Security Features and Response - -Netdata Cloud offers a variety of security features, including infrastructure-level dashboards, centralized alerts -notifications, auditing logs, and role-based access to different segments of the infrastructure. The cloud service -employs several protection mechanisms against DDoS attacks, such as rate-limiting and automated blacklisting. It also -uses static code analysers to prevent other types of attacks. - -In the event of potential security vulnerabilities or incidents, Netdata Cloud follows the same process as the Netdata -agent. Every report is acknowledged and analyzed by the Netdata team within three working days, and the team keeps the -reporter updated throughout the process. - -### User Customization - -Netdata Cloud uses the highest level of security. There is no user customization available out of the box. Its security -settings are designed to provide maximum protection for all users. We are offering customization (like custom SSO -integrations, custom data retention policies, advanced user access controls, tailored audit logs, integration with other -security tools, etc.) on a per contract basis. - -### Deleting Personal Data - -Users who wish to remove all personal data (including email and activities) can delete their cloud account by logging -into Netdata Cloud and accessing their profile. - -## User Privacy and Data Protection - -Netdata Cloud is built with an unwavering commitment to user privacy and data protection. We understand that our users' -data is both sensitive and valuable, and we have implemented stringent measures to ensure its safety. - -### Data Collection - -Netdata Cloud collects minimal personal information from its users. The only personal data required to create an account -and use the service is an email address. This email address is used for product and marketing communications. -Additionally, the IP address used to access Netdata Cloud is stored in web proxy access logs. - -### Data Usage - -The collected email addresses are stored in our production database on Amazon Web Services (AWS) and copied to Google -BigQuery, our data lake, for analytics purposes. These analytics are crucial for our product development process. If a -user accepts the use of analytical cookies, their email address and IP are stored in the systems we use to track -application usage (Google Analytics, Posthog, and Gainsight PX). Subscriptions and Payments data are handled by Stripe. - -### Data Sharing - -Netdata Cloud does not share any personal data with third parties, ensuring the privacy of our users' data, but Netdata -Cloud does use third parties for its services, including, but not limited to, Google Cloud and Amazon Web Services for -its infrastructure, Stripe for payment processing, Google Analytics, Posthog and Gainsight PX for analytics. - -### Data Protection - -We use state-of-the-art security measures to protect user data from unauthorized access, use, or disclosure. All -infrastructure data visible on Netdata Cloud passes through the Agent-Cloud Link (ACLK) mechanism, which securely -connects a Netdata Agent to Netdata Cloud. The ACLK is encrypted, safe, and is only established if the user connects -their node. All data in transit between a user and Netdata Cloud is encrypted using TLS. - -### User Control over Data - -Netdata provides its users with the ability to access, retrieve, correct, and delete their personal data stored in -Netdata Cloud. This ability may occasionally be limited due to temporary service outages for maintenance or other -updates to Netdata Cloud, or when it is technically not feasible. If a customer is unable to delete personal data via -the self-services functionality, Netdata deletes the data upon the customer's written request, within the timeframe -specified in the Data Protection Agreement (DPA), and in accordance with applicable data protection laws. - -### Compliance with Data Protection Laws - -Netdata Cloud is fully compliant with data protection laws like the General Data Protection Regulation (GDPR) and the -California Consumer Privacy Act (CCPA). - -### Data Transfer - -Data transfer within Netdata Cloud is secure and respects the privacy of the user data. The Netdata Agent establishes an -outgoing secure WebSocket (WSS) connection to Netdata Cloud, ensuring that the data is encrypted when in transit. - -### Use of Tracking Technologies - -Netdata Cloud uses analytical cookies if a user consents to their use. These cookies are used to track the usage of the -application and are stored in systems like Google Analytics, Posthog and Gainsight PX. - -### Data Breach Notification Process - -In the event of a data breach, Netdata has a well-defined process in place for notifying users. The details of this -process align with the standard procedures and timelines defined in the Data Protection Agreement (DPA). - -We continually review and update our privacy and data protection practices to ensure the highest level of data safety -and privacy for our users. - -## Compliance with Regulations - -Netdata is committed to ensuring the security, privacy, and integrity of user data. It complies with both the General -Data Protection Regulation (GDPR), a regulation in EU law on data protection and privacy, and the California Consumer -Privacy Act (CCPA), a state statute intended to enhance privacy rights and consumer protection for residents of -California. - -### Compliance with GDPR and CCPA - -Compliance with GDPR and CCPA are self-assessment processes, and Netdata has undertaken thorough internal audits and -controls to ensure it meets all requirements. - -As per request basis, any customer may enter with Netdata into a data processing addendum (DPA) governing customer’s -ability to load and permit Netdata to process any personal data or information regulated under applicable data -protection laws, including the GDPR and CCPA. - -### Data Transfers - -While Netdata Agent itself does not engage in any cross-border data transfers, certain personal and infrastructure data -is transferred to Netdata Cloud for the purpose of providing its services. The metric data collected and processed by -Netdata Agents, however, stays strictly within the user's infrastructure, eliminating any concerns about cross-border -data transfer issues. - -When users utilize Netdata Cloud, the metric data is streamed directly from the Netdata Agent to the users’ web browsers -via Netdata Cloud, without being stored on Netdata Cloud's servers. However, user identification data (such as email -addresses) and infrastructure metadata necessary for Netdata Cloud's operation are stored in data centers in the United -States, using compliant infrastructure providers such as Google Cloud and Amazon Web Services. These transfers and -storage are carried out in full compliance with applicable data protection laws, including GDPR and CCPA. - -### Privacy Rights - -Netdata ensures user privacy rights as mandated by the GDPR and CCPA. This includes the right to access, correct, and -delete personal data. These functions are all available online via the Netdata Cloud User Interface (UI).
