Working With Us
- Create an issue in our issue tracker dedicated to Business as Usual (BAU) activities and general inquiries.
- It is not necessary to
@mention anyone. In case you want to mention the whole team, use the @gitlab-com/gl-security/engineering-and-research/security-logging handle on GitLab.com.
- You can also chat with us on Slack in the dedicated
#security-logging channel or by tagging us @security-logging-team.
The Security Logging Team can be contacted in Slack using the #security-logging channel, the #security channel, or the #security-department channel. You can also contribute, comment, view, or interact with us in our team repo.
How We Work
We are an internal customer focused and customer driven team. Our customers drive our priorities and help us define our responsibilities. We work to balance this with a risk based approach aimed at reducing and minimizing security risk at GitLab. Additionally, we embrace the DevOps model, software defined infrastructures, a cloud first approach, modular decoupled architectures, self-serviceability, and automate when and wherever possible.
Meetings and Scheduled Calls
Our preference is to work asynchronously, within our project issue tracker as described in the project management section below.
The team does have set of regular synchronous calls:
- A weekly team sync to discuss progress, blockers, and anything related to the InfraSec team.
- A quarterly team retrospective to reflect on what went well in the previous quarter, and discuss what can be improved going forward.
- 1-1s between Individual Contributors and the Engineering Manager.
Team Pages
Project Management
We use Epics, Issues, and Issue Boards to organize our work, as they complement each other:
- The single source of truth for engineering work is the Security-Logging Sub-Group in GitLab. All Epics will be collected at this level.
- Having all projects at this level allows us to use a single list for prioritization and enables us to prioritize
work for different services alongside each other.
- Projects are prioritized in line with Security Logging Board.
Team Planning
- For the long term strategy of the InfraSec Team, you can refer to:
- From a tactical point of view, you can refer to:
Project Ownership
Each project has an owner who is responsible for delivering the project.
The owner needs to:
- Regularly update the status in the Epic description and milestones.
- Work with others to move project issues through the boards.
Labels
Please use the following labels for general work only:
| Label |
Use Case |
~"☁️ SecLog" |
Team Label (to be included in every project-related issue) |
~"SecLog::Incoming-Requests" |
For new issues which need to be triaged |
Design Documents
Before starting a new project, the team is encouraged
to define software designs through design docs.
These design doc documents the high level implementation strategy and key design decisions with emphasis on the trade-offs that were considered during those decisions.
To start discussing a new design:
- Create a new issue in the InfraSec Team Charter repo
- Select the
design_doc template
- Fill the data as requested
Security Logging Program Roles and Responsibilities
The following roles and responsibilities are specific to the management and execution of the Security Logging Program which is overall the responsibility of the Product Security sub-department.
Security Logging is responsible for
- Ownership of, management, and maintenance of our SIEM
- Coordinating and executing log source ingestion
- Overall management and coordination of the security logging program
- Ownership of the to be developed Security Logging Standard
- Subject matter experts with regards to the operation and management of the SIEM
- The data movement and archive of security logging data currently held in Panther
- Capacity planning and forecasting of licensing and infrastructure costs, as a shared responsibility with InfraSec
AppSec is responsible for
- Working closely with Development to ensure the Security Logging Standard is adopted and followed
- Advising SecLogging when log formats will change, prior to the change occurring, if known
- Advising SIRT on any log sources from the application that they may be interested in and recommend new high-value detection considerations to SIRT for new product features or capabilities
- Helping to bridge the gap between the Security Logging Team and the software engineering teams
- Helping to identify logging gaps in the application and proposing solutions to close the gaps
- Aiding and guiding engineering teams that design, develop, or deploy something new on what to log and how to get the logs into the SIEM. This includes logs that SIRT needs to complete investigations.
InfraSec is responsible for

- Guiding and informing the InfraSec and AppSec teams on logging data critical to SIRT through collaboration and maintenance of the development of the Security Logging Standard
- Reporting to the Security Logging Team when logs:
- Are no longer needed
- Are incomplete
- Need format improvements or corrections
- Require more verbosity
- Have efficiency opportunities (e.g. we only use a small portion of sizable logs)
Everyone else across Security is responsible for
- Making requests of the Security Logging Team for logs that you need to execute your responsibilities, we will have a documented process for this soon
- Submitting issues to SIRT when you have detection suggestions where we have a high return on investment
