description: This search is to detect a pushed or commit to develop branch. This is
|
|
to avoid unwanted modification to develop without a review to the changes. Ideally
|
|
in terms of devsecops the changes made in a branch and do a PR for review. of course
|
|
in some cases admin of the project may did a changes directly to master branch
|
|
data_source: []
|
|
search: '`github` branches{}.name = main OR branches{}.name = develop | stats count
|
|
min(_time) as firstTime max(_time) as lastTime by commit.author.html_url commit.commit.author.email
|
|
commit.author.login commit.commit.message repository.pushed_at commit.commit.committer.date
|
|
| eval phase="code" | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`
|
|
| `github_commit_in_develop_filter`'
|
|
how_to_implement: To successfully implement this search, you need to be ingesting
|
|
logs related to github logs having the fork, commit, push metadata that can be use
|
|
to monitor the changes in a github project.
|
|
known_false_positives: admin can do changes directly to develop branch
