The blog post explores the differences between macOS and Windows in handling system-level events crucial for endpoint security analysis, particularly focusing on file and network events. For file events, Windows utilizes a powerful and flexible minifilter driver that offers granular control, while macOS employs the Endpoint Security (ES) framework, which simplifies usage but limits developer control, requiring specific entitlements from Apple. In network event handling, Windows provides the Windows Filtering Platform (WFP) for comprehensive network traffic filtering across various layers, whereas macOS has transitioned from Network Kernel Extensions (NKE) to the more simplified and restricted Network Extension framework. The discussion highlights Windows' approach of empowering third-party developers with extensive tools and Apple's strategy of maintaining control by offering highly wrapped APIs, emphasizing the importance of understanding these differences for effective cybersecurity practices.
