OpenStack Security
vmt-process
Security is a fundamental goal of the OpenStack architecture and needs to be addressed at all layers of the stack. Like any complex, evolving system security has to be vigilantly pursued, and exposures eliminated. We need your help.
OpenStack has two mechanisms for communicating security information with downstream stakeholders, "Advisories" and "Notes". OpenStack Security Advisories (OSSA) are created to deal with severe security issues in OpenStack for which a fix is available - OSSA's are issued by the OpenStack Vulnerability Management Team (VMT). OpenStack Security Notes (OSSN) are used for security issues which do not qualify for an advisory, typically design issues, deployment and configuration vulnerabilities.
How to report security issues to OpenStack
If you think you've identified a vulnerability, please work with us to rectify and disclose the issue responsibly. We provide two ways to report issues to the OpenStack Vulnerability Management Team depending on how sensitive the issue is:
- Search for the corresponding project at https://launchpad.net/ and after selecting it, click the 'Report a bug' link at the right. Fill in the 'Summary' and 'Further information' fields describing the issue, then click the 'This bug is a security vulnerability' checkbox near the bottom of the page before submitting it. This will make the bug Private and only accessible to the Vulnerability Management Team.
- If the issue is extremely sensitive or you're otherwise unable to
use the bug tracker directly, please send an E-mail message to one or
more of the Team's members. You're encouraged to encrypt messages to
their OpenPGP keys, which can be found linked below and also on the
keyserver network with the following fingerprints:

Security information for OpenStack deployers
There are four main sources of security guidance for OpenStack deployers:
- OpenStack Security Advisories (OSSA)
- OpenStack Security Notes (OSSN)
- OpenStack Security Guide
- OpenStack Security Project blog
OpenStack Security Advisories (OSSA)
Recent OSSAs:
./ossa/*
You can find the complete list of published advisories here:
ossalist
OpenStack Security Notes
Security Notes advise users of security related issues. Security notes are similar to advisories; they often address vulnerabilities in third party tools typically used within OpenStack deployments and provide guidance on common configuration mistakes that can result in an insecure operating environment.
The complete set of security notes is available online, but they are also published on the OpenStack mailing list when they are released.
OpenStack Security Guide
The OpenStack Security Guide provides best practice information for OpenStack deployers. This guide was written by a community of security experts from the OpenStack Security Project, based on experience gained while hardening OpenStack deployments. The guide covers topics including compute and storage hardening, rate limiting, compliance, and cryptography; it is the starting point for anyone looking to securely deploy OpenStack.

OpenStack Security Project blog
The Security Project also maintain a blog, with posts about current and future projects, presentations and other information that doesnt fit in anywhere else: http://openstack-security.github.io/
Security information for OpenStack developers
How to propose and review a security patch
Note
The patch development and review process for security patches is different from normal patches in OpenStack. Because the gerrit review process is public, all security bugs must have patches proposed to and reviewed in the Launchpad bug report comments.
After a patch for the reported bug has been developed locally, you the patch author need to share that with the community. This is a simple process, but it is different than the normal OpenStack workflow.
Export it using the format-patch command:
git format-patch --stdout HEAD~1 >path/to/local/file.patch
Now you have the patch saved locally and you can attach it in a comment on the Launchpad bug page.
For reviewers, to review that attached patch, run the following command:
git am <~path/to/local/file.patch
This applies the patch locally as a commit, including the commit message, author, date, and all other metadata. However, if the patch author did not use format-patch to export the patch (perhaps they only used git show >local.patch), then the patch can be applied locally with:
git apply path/to/local/file.patch
Secure development guidelines
The OpenStack security team have collaboratively developed this set of guidelines and best practices to help avoid common mistakes that lead to security vulnerabilities within the OpenStack platform.

OpenStack Security Project
The OpenStack Security Project runs an number of initiatives aimed at improving the overall security of OpenStack projects and ensuring that security incidents are handled in a coordinated fashion. Key initiatives that fall within the security project's areas of responsibility are outlined below.
Vulnerability Management
An autonomous subgroup of vulnerability management specialists with in the security team make up the OpenStack vulnerability management team (VMT). Their job is facilitating the reporting of vulnerabilities, coordinating security fixes and handling progressive disclosure of the vulnerability information. Specifically, they are responsible for the following functions:
- Vulnerability Management: All vulnerabilities discovered by community members (or users) can be reported to the Team.
- Vulnerability Tracking: The Team will curate a set of vulnerability related issues in the issue tracker. Some of these issues will be private to the Team and the affected product leads, but once remediated, all vulnerabilities will be public.
- Responsible Disclosure: As part of our commitment to work with the security community, the Team will ensure that proper credit is given to security researchers who responsibly report issues in OpenStack.
See vmt-process

details on our open process.
Security tool development
The Security project are constantly looking at ways to introduce tooling and automation to improve the overall security of OpenStack projects. Some of these projects are outlined below.
Bandit - static analysis for Python
Bandit is a security static analysis tool for Python source code, utilizing the ast module from the Python standard library. The ast module is used to convert source code into a parsed tree of Python syntax nodes. Bandit allows users to define custom tests that are performed against those nodes. At the completion of testing, a report is generated that lists security issues identified within the target source code.
Bandit is currently a stand-alone tool which can be downloaded by end-users and run against arbitrary source code. Although early in development it is already adding value to the OpenStack code base with several projects leveraging it in their CI gate tests. As the project matures the desire is to see widespread adoption of Bandit in the OpenStack community.
Bandit can be obtained by cloning the repository. The README.rst file contains documentation regarding installation, usage, and configuration.
Anchor - ephemeral PKI
Anchor is a lightweight, open source, Public Key Infrastructure (PKI), which uses automated provisioning of short-term certificates to enable cryptographic trust in OpenStack services. Certificates are typically valid for 12-24 hours and are issued based on the result from a policy enforcing decision engine. Short term certificates enable passive revocation, to bypass the issues with the traditional revocation mechanisms used in most PKI deployments.
