There are number of different access paths you need to be concerned from security standpoint: Practice #10: always have at least one copy of repository that you can trust and treat as secure. While it is great from a developer’s perspective, it doesn’t sound so good from a security point. Git is distributed revision control system which means there can be an unlimited number of repositories of the project at any particular time. Review unsigned commits to assure there is no unauthorized one. Practice #9 is great for newly created projects but how it can be implemented in case of already existing repositories with millions of unsigned commits and tags? The answer is simple: introduce signing as a requirement and create a signed tag marking a point from which all commits must be signed. Practice #9: All committers must sign – otherwise this mechanism makes no sense. You should use –S switch when using git “merge” command to sign resulting merge commit. In such case commits without trusted and valid PGP/GPG signature will be rejected. You can also use signing mechanism – starting from git 1.8.3 version – during marge and pull operations. Verifying commits and tags is also very straightforward. To sign a commit you can use –S switch like below:

Practice #8: Assign strong password to protect private keys.Īfter your key gets created you have to tell about it git using following commands: Such keys are harder or impossible to “revoke” in case of compromise, especially when no revocation certificate is available, or you’ve lost access to your private key. Practice #7: Do not generate PGP/GPG keys with an infinite validity period. In case of compromise, you will be able to use it to inform others that your compromised key isn’t valid any longer.
Right after generating your private key, generate revocation certificate (gpg –gen-revoke option) and store it in a safe place. Report if it gets compromised and revoke the key immediately from key servers. Practice #5: Do not trust a PGP/GPG key by default – be sure you’ve got a trusted public key from a right person. Practice #4: Do not use short keys for PGP/GPG. Following Practice #3 you should use both options.īefore any user can sign commit or tag, he needs to have his pair of PGP private and public keys. Signing commits and tagsįortunately, for some time, git supports the cryptographic signing of commits and tags. Practice #3: never assume identity-based on username / email. Hence, I do not define it as a best practice but rather a point to be addressed in you security policy or Secure Development Lifecycle process. The quick answer will be no, but if you think about it for a while it may turn out that answer will depend on project type and requirements. This feature brings another question: should you allow users to use different identities per project. Git also allows defining an identity locally for a particular repository using –local option.
Git config –global user.email same result can be achieved by editing git configuration files which are plain text. For such case (or for malicious user) git allow to enforce identity using following commands for example: There are some cases when git can’t “detect” your identity or guess it wrongly.

Practice #2: never use privileged account to develop code and commit (you can use system facilities like sudo, does or runs depending on operating system you are using) Practice #1: never use shared, or system accounts like root, nobody, www, etc.
This brings us to the first best practices: In reality, anyone can create a user account with data imitating legal user account. The problem is that this process is based on data gather from an operating system based on user name and account configuration. Git tries its best to detect user identity when committing changes. Proper user identification and authorization is one of most fundamental security requirements. Practices presented below can easily be integrated into your Secure Development Lifecycle process if you deployed one already. This article provides minimal git security best practices.
WHAT IS GIT BASH AND SHOULD YOU USE IT SOFTWARE
SCM software and services are one of the best high-profile targets as unauthorized change within few lines of code may result in half of the world with the same vulnerability or backdoor installed. As particular technology gets widely used, it becomes a high profile attack target. Usage in some high-profile open-source projects like Linux or Raspberry Pi and support from vendors like GitHub and GitLab definitively helped to gain fame. In recent years git has become one of most popular SCM/ Version Control systems.
