Security and Privacy

Motivation

This codebase is responsible for implementing security and privacy features for GitLab Discussions. It ensures that user data is protected and that the application is secure from attacks.

Security Features

The codebase implements several security features, including:

• Authentication and Authorization: Users are authenticated and authorized to access resources based on their permissions.
• Input Validation: User input is validated to prevent injection attacks such as SQL injection and cross-site scripting (XSS).
• Data Encryption: Sensitive data, such as user passwords, is encrypted at rest and in transit.
• Security Auditing: Logs are kept of user activity and security events.

Privacy Features

The codebase also implements privacy features to protect user data, such as:

• Data Minimization: Only the necessary data is collected and stored.
• Data Retention Policies: Data is deleted after a certain period of time.
• User Consent: Users are given the opportunity to consent to the collection and use of their data.
• Data Portability: Users can download their data in a portable format.
• Right to be Forgotten: Users can request that their data be deleted.

Configuration

The Security and Privacy features can be configured through the GitLab application settings.

Examples

Data Encryption:

# app/models/discussion.rb
          class Discussion < ApplicationRecord
            # ...
            has_secure_password
            # ...
          end
          

This code snippet uses has_secure_password to encrypt user passwords.

Data Retention Policies:

# config/initializers/data_retention.rb
          Rails.application.config.data_retention_policies = {
            "discussions" => {
              "expiration_period" => 365,
              "expiration_unit" => "days"
            }
          }
          

This code snippet defines a data retention policy for Discussions, expiring them after 365 days.

User Consent:

# app/views/discussions/new.html.erb
          <%= form_for @discussion do |f| %>
            <%= f.check_box :accept_terms %>
            <%= f.label :accept_terms, "I agree to the Terms of Service" %>
            # ...
          <% end %>
          

This code snippet displays a checkbox that users must check to agree to the Terms of Service before creating a Discussion.

Data Portability:

# app/controllers/discussions_controller.rb
          class DiscussionsController < ApplicationController
            # ...
            def download_data
              @discussions = current_user.discussions
              # ...
            end
            # ...
          end
          

This code snippet allows users to download their Discussions in a portable format.

Right to be Forgotten:

# app/controllers/discussions_controller.rb
          class DiscussionsController < ApplicationController
            # ...
            def destroy
              @discussion = Discussion.find(params[:id])
              @discussion.destroy
              # ...
            end
            # ...
          end
          

This code snippet allows users to delete their Discussions.

Testing

The Security and Privacy codebase is extensively tested to ensure that it meets the highest standards.
