Implement protective limits for network operations to prevent resource exhaustion and denial-of-service attacks. Network operations should have bounded resource consumption to avoid overwhelming servers or clients. Key areas to address: 1. **Pagination limits**: Set maximum page counts and track visited pages to prevent infinite loops in collection traversal 2. **Connection management**: Consume response bodies within reasonable limits (e.g., 1MB) for persistent connections, closing connections when limits are exceeded 3. **Subscription churn**: Avoid creating excessive per-resource network channels that cause high subscribe/unsubscribe load Example implementation for pagination protection: ```ruby def collection_items(collection_or_uri) visited_pages = Set.new page_count = 0 max_pages = 50 while collection.is_a?(Hash) && page_count < max_pages return if visited_pages.include?(collection['id']) visited_pages.add(collection['id']) # Process items... page_count += 1 collection = collection['next'].present? ? fetch_collection(collection['next']) : nil end end ``` This prevents attackers from creating infinite pagination loops while ensuring legitimate large collections can still be processed within reasonable bounds.
