 Basics 12/17 ●

  • Identification

    EVE-OS EVE aims to develop an open, agnostic and standardized architecture unifying the approach to developing and orchestrating cloud-native applications across the enterprise on-premises edge. It offers users new levels of control through hardware-assisted virtualization of on-prem edge devices. Once installed, EVE has direct access to and control of underlying resources and provides standard APIs that allow more efficient use of resources and can effectively partition hardware to increase workload consolidation and application multi-tenancy.

    EVE supports both ARM and Intel architectures and requires hardware-assisted virtualization. While EVE can run on a board as small as a $20 Orange Pi, the sweet spot for its deployment are IoT Gateways and Industrial PCs.

    To get its job done, EVE leverages a lot of great open source projects: Xen Project, Linuxkit and Alpine Linux just to name a few. All of that functionality is being orchestrated by the Go microservices available under pkg/pillar. Why pillar? Well, because pillar is the kind of a monolith we need to break out into true, individual microservices under pkg/.

  • Prerequisites


    Enough for a badge!

    The project MUST achieve a passing level badge. [achieve_passing]

  • Basic project website content


    Enough for a badge!

    The information on how to contribute MUST include the requirements for acceptable contributions (e.g., a reference to any required coding standard). (URL required) [contribution_requirements]

    The contribution must pass CircleCI and be signed. https://github.com/lf-edge/eve/blob/master/CONTRIBUTING.md


  • Project oversight


    Enough for a badge!

    The project SHOULD have a legal mechanism where all developers of non-trivial amounts of project software assert that they are legally authorized to make these contributions. The most common and easily-implemented approach for doing this is by using a Developer Certificate of Origin (DCO), where users add "signed-off-by" in their commits and the project links to the DCO website. However, this MAY be implemented as a Contributor License Agreement (CLA), or other legal mechanism. (URL required) [dco]

    DCO is required https://github.com/lf-edge/eve/blob/master/CONTRIBUTING.md


    Enough for a badge!

    The project MUST clearly define and document its project governance model (the way it makes decisions, including key roles). (URL required) [governance]

    This is an LF Edge project. The governance is located here https://github.com/lf-edge/eve/blob/master/CONTRIBUTING.md


    Enough for a badge!

    The project MUST adopt a code of conduct and post it in a standard location. (URL required) [code_of_conduct]

    This is an LF Edge Project, so it follows LFEdge's code of conduct. https://lfprojects.org/policies/code-of-conduct/


    Unknown required information, not enough for a badge.

    The project MUST clearly define and publicly document the key roles in the project and their responsibilities, including any tasks those roles must perform. It MUST be clear who has which role(s), though this might not be documented in the same way. (URL required) [roles_responsibilities]

    Unknown required information, not enough for a badge.

    The project MUST be able to continue with minimal interruption if any one person dies, is incapacitated, or is otherwise unable or unwilling to continue support of the project. In particular, the project MUST be able to create and close issues, accept proposed changes, and release versions of software, within a week of confirmation of the loss of support from any one individual. This MAY be done by ensuring someone else has any necessary keys, passwords, and legal rights to continue the project. Individuals who run a FLOSS project MAY do this by providing keys in a lockbox and a will providing any needed legal rights (e.g., for DNS names). (URL required) [access_continuity]

    Enough for a badge!

    The project MUST make an effort to keep the documentation consistent with the current version of the project results (including software produced by the project). Any known documentation defects making it inconsistent MUST be fixed. If the documentation is generally current, but erroneously includes some older information that is no longer true, just treat that as a defect, then track and fix as usual. [documentation_current]

    Keeping the documentation in github and the reviewers pointing out docs which need to be updated (or information added) as part of PR reviews.


    Unknown required information, not enough for a badge.

  • Accessibility and internationalization


    Unknown required information, not enough for a badge.

    The project (both project sites and project results) SHOULD follow accessibility best practices so that persons with disabilities can still participate in the project and use the project results where it is reasonable to do so. [accessibility_best_practices]

    Enough for a badge!

    The software produced by the project SHOULD be internationalized to enable easy localization for the target audience's culture, region, or language. If internationalization (i18n) does not apply (e.g., the software doesn't generate text intended for end-users and doesn't sort human-readable text), select "not applicable" (N/A). [internationalization]

    The software does not generate text for end users; users interact with a separate EVE controller through cli, UI, APIs etc.


  • Other


    Enough for a badge!

    If the project sites (website, repository, and download URLs) store passwords for authentication of external users, the passwords MUST be stored as iterated hashes with a per-user salt by using a key stretching (iterated) algorithm (e.g., Argon2id, Bcrypt, Scrypt, or PBKDF2). If the project sites do not store passwords for this purpose, select "not applicable" (N/A). [sites_password_security]

    Using github and lf-edge websites for this.


  • Previous versions


    Unknown required information, not enough for a badge.

    The project MUST maintain the most often used older versions of the product or provide an upgrade path to newer versions.

    The project MUST use an issue tracker for tracking individual issues. [report_tracker]

    issues are single issues


  • Vulnerability report process


    Enough for a badge!

    The project MUST give credit to the reporter(s) of all vulnerability reports resolved in the last 12 months, except for the reporter(s) who request anonymity.

    Using various linters as part of golangcilint to enforce coding style.


  • Working build system


    Unknown required information, not enough for a badge.

    Build systems for native binaries MUST honor the relevant compiler and linker (environment) variables passed in to them (e.g., CC, CFLAGS, CXX, CXXFLAGS, and LDFLAGS) and pass them to compiler and linker invocations. A build system MAY extend them with additional flags; it MUST NOT simply replace provided values with its own. If no native binaries are being generated, select "not applicable" (N/A). [build_standard_variables]

    Unknown required information, not enough for a badge.

    The build and installation system SHOULD preserve debugging information if they are requested in the relevant flags (e.g., "install -s" is not used). If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_preserve_debug]

    Unknown required information, not enough for a badge.

    The build system for the software produced by the project MUST NOT recursively build subdirectories if there are cross-dependencies in the subdirectories. If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_non_recursive]

    Enough for a badge!

    The project MUST be able to repeat the process of generating information from source files and get exactly the same bit-for-bit result. If no building occurs (e.g., scripting languages where the source code is used directly instead of being compiled), select "not applicable" (N/A). [build_repeatable]

    See https://github.com/lf-edge/eve/blob/master/docs/EVE-IMAGE-REPRODUCIBILITY.md


  • Installation system


    Enough for a badge!

    The project MUST provide a way to easily install and uninstall the software produced by the project using a commonly-used convention. [installation_common]

    EVE installs on bare metal using its own installer (from USB medium, PXE booting, etc) See https://github.com/lf-edge/eve/blob/master/docs/README.md#installing-eve-on-edge-nodes


    Enough for a badge!

    The installation system for end-users MUST honor standard conventions for selecting the location where built artifacts are written to at installation time. For example, if it installs files on a POSIX system it MUST honor the DESTDIR environment variable. If there is no installation system or no standard convention, select "not applicable" (N/A). [installation_standard_variables]

    Installs on designated disk drives on bare metal.


    Enough for a badge!

    The project MUST provide a way for potential developers to quickly install all the project results and support environment necessary to make changes, including the tests and test environment. This MUST be performed with a commonly-used convention. [installation_development_quick]

    Can run tests using either the Eden part of the project (which installs and runs the results under qemu) or manually using Makefile targets (which can run either the installer or a live image under qemu).


  • Externally-maintained components


    Enough for a badge!

    The project MUST list external dependencies in a computer-processable way. (URL required) [external_dependencies]

    make sbom uses syft to produce a SPDX file. Currently that about is manually curated to produce https://wiki.lfedge.org/display/EVE/SW+Components+and+Licensing and going forward this will be automatically generated and added to the release information at e.g., https://github.com/lf-edge/eve/releases/latest


    Enough for a badge!

    Projects MUST monitor or periodically check their external dependencies (including convenience copies) to detect known vulnerabilities, and fix exploitable vulnerabilities or verify them as unexploitable. [dependency_monitoring]

    Using dependabot for automatic detection for all of the golang packages and periodic manual checks for CVEs for other packages.


    Enough for a badge!

    The project MUST either:
    1. make it easy to identify and update reused externally-maintained components; or
    2. use the standard components provided by the system or programming language.
    Then, if a vulnerability is found in a reused component, it will be easy to update that component. [updateable_reused_components]

    The output of the project is an image which is installed on target systems, typcally on bare metal, and not a piece of software running on top of an operating system. The external components are pulled in during the build process and identified in the produced SBOM output. Documentation in BUILD.md indicates how one updates e.g., the base packages from the Linux distro (currently Alpine).


    Enough for a badge!

    The project SHOULD avoid using deprecated or obsolete functions and APIs where FLOSS alternatives are available in the set of technology it uses (its "technology stack") and to a supermajority of the users the project supports (so that users have ready access to the alternative). [interfaces_current]

    golangcilint indicates what has been deprecated and this is run as part of each PR.


  • Automated test suite


    Enough for a badge!

    An automated test suite MUST be applied on each check-in to a shared repository for at least one branch. This test suite MUST produce a report on test success or failure. [automated_integration_testing]

    The GH actions run on each PR run both unit tests and end-to-end tests (latter using the Eden and Adam components of the project).


    Unknown required information, not enough for a badge.

    The project MUST add regression tests to an automated test suite for at least 50% of the bugs fixed within the last six months. [regression_tests_added50]

    Unknown required information, not enough for a badge.

    The project MUST have FLOSS automated test suite(s) that provide at least 80% statement coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_statement_coverage80]

  • New functionality testing


    Unknown required information, not enough for a badge.

    The project MUST have a formal written policy that as major new functionality is added, tests for the new functionality MUST be added to an automated test suite. [test_policy_mandated]

    Not enough for a badge.

    The project MUST include, in its documented instructions for change proposals, the policy that tests are to be added for major new functionality. [tests_documented_added]

    The project currently operates with an informal rule.


  • Warning flags


    Enough for a badge!

    Projects MUST be maximally strict with warnings in the software produced by the project, where practical. [warnings_strict]

    Using golangcilint to flag warnings in go code.


  • Secure development knowledge


    Enough for a badge!

    The project MUST implement secure design principles (from "know_secure_design"), where applicable. If the project is not producing software, select "not applicable" (N/A). [implement_secure_design]

    See https://github.com/lf-edge/eve/blob/master/docs/SECURITY.md


  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    Enough for a badge!

    The default security mechanisms within the software produced by the project MUST NOT depend on cryptographic algorithms or modes with known serious weaknesses (e.g., the SHA-1 cryptographic hash algorithm or the CBC mode in SSH). [crypto_weaknesses]

    Code reviews and periodic PEN testing which includes reviewing the source code.


    Enough for a badge!

    The project SHOULD support multiple cryptographic algorithms, so users can quickly switch if one is broken. Common symmetric key algorithms include AES, Twofish, and Serpent. Common cryptographic hash algorithm alternatives include SHA-2 (including SHA-224, SHA-256, SHA-384 AND SHA-512) and SHA-3. [crypto_algorithm_agility]

    Security in flight is done using TLS hence we leverage its algorithm agility. Security at rest is done using fscrypt and native ZFS encryption and those can be reconfigured in the source code to use different algorithms.


    Enough for a badge!

    The project MUST support storing authentication credentials (such as passwords and dynamic tokens) and private cryptographic keys in files that are separate from other information (such as configuration files, databases, and logs), and permit users to update and replace them without code recompilation. If the project never processes authentication credentials and private cryptographic keys, select "not applicable" (N/A). [crypto_credential_agility]

    The primary API access to EVE uses essentially mTLS (TLS with client certificates) where the client key pair is generated in a TPM chip (if available) so that the private key never leaves the TPM chip. On top of this an EVE controller can generate and sign a time-limited JWT for debug access to the system, which is validated using the configured root of trust to the controller. The project handles user credentals (could be remote datastore credentials e.g., for S3 or Azure, WiFi credentials, or cloud-init files potentially containing credentials) using an additional object encryption layer (using ECDH + AES) such that these credentials are never stored in clear text in the file system; clear text is only in the memory of the running processes.


    Enough for a badge!

    The software produced by the project SHOULD support secure protocols for all of its network communications, such as SSHv2 or later, TLS1.2 or later (HTTPS), IPsec, SFTP, and SNMPv3. Insecure protocols such as FTP, HTTP, telnet, SSLv3 or earlier, and SSHv1 SHOULD be disabled by default, and only enabled if the user specifically configures it. If the software produced by the project does not support network communications, select "not applicable" (N/A). [crypto_used_network]

    Using SSHv2 and TLS 1.3 and 1.2.


    Enough for a badge!

    The software produced by the project SHOULD, if it supports or uses TLS, support at least TLS version 1.2. Note that the predecessor of TLS was called SSL. If the software does not use TLS, select "not applicable" (N/A). [crypto_tls12]

    TLS 1.3 preferred and TLS 1.2 supported.


    Enough for a badge!

    The software produced by the project MUST, if it supports TLS, perform TLS certificate verification by default when using TLS, including on subresources. If the software does not use TLS, select "not applicable" (N/A). [crypto_certificate_verification]

    Using the standard golang https/tls client code with certificate verification enabled.


    Enough for a badge!

    The software produced by the project MUST, if it supports TLS, perform certificate verification before sending HTTP headers with private information (such as secure cookies). If the software does not use TLS, select "not applicable" (N/A). [crypto_verification_private]

    Done using golang https client package.


  • Secure release


    Unknown required information, not enough for a badge.

    The project MUST cryptographically sign releases of the project results intended for widespread use, and there MUST be a documented process explaining to users how they can obtain the public signing keys and verify the signature(s). The private key for these signature(s) MUST NOT be on site(s) used to directly distribute the software to the public. If releases are not intended for widespread use, select "not applicable" (N/A). [signed_releases]

    Unknown required information, not enough for a badge.

    It is SUGGESTED that in the version control system, each important version tag (a tag that is part of a major release, minor release, or fixes publicly noted vulnerabilities) be cryptographically signed and verifiable as described in signed_releases. [version_tags_signed]

  • Other security issues


    Unknown required information, not enough for a badge.

    The project results MUST check all inputs from potentially untrusted sources to ensure they are valid (an *allowlist*), and reject invalid inputs, if there are any restrictions on the data at all. [input_validation]

    Unknown required information, not enough for a badge.

    Hardening mechanisms SHOULD be used in the software produced by the project so that software defects are less likely to result in security vulnerabilities. [hardening]

    Unknown required information, not enough for a badge.

    The project MUST provide an assurance case that justifies why its security requirements are met. The assurance case MUST include: a description of the threat model, clear identification of trust boundaries, an argument that secure design principles have been applied, and an argument that common implementation security weaknesses have been countered. (URL required) [assurance_case]

  • Static code analysis


    Enough for a badge!

    The project MUST use at least one static analysis tool with rules or approaches to look for common vulnerabilities in the analyzed language or environment, if there is at least one FLOSS tool that can implement this criterion in the selected language. [static_analysis_common_vulnerabilities]

    golangcilint runs gosec


  • Dynamic code analysis


    Enough for a badge!

    If the software produced by the project includes software written using a memory-unsafe language (e.g., C or C++), then at least one dynamic tool (e.g., a fuzzer or web application scanner) MUST be routinely used in combination with a mechanism to detect memory safety problems such as buffer overwrites. If the project does not produce software written in a memory-unsafe language, choose "not applicable" (N/A). [dynamic_analysis_unsafe]

    No C or C++
