Development of Kernel-Level File Activity Monitoring and Access Control System

The organization faces difficulties in accurately monitoring file access activities across network shares at the kernel level, resulting in limited visibility into user actions and insufficient enforcement of access rules, which could compromise security and compliance requirements.

A mid-sized enterprise specializing in network management and security services, requiring advanced file system monitoring capabilities in a kernel environment.

• Implement an advanced kernel-level file system filter driver to monitor and log detailed file access activities, including user identity, in real-time.
• Enrich file activity data with comprehensive user and session parameters to facilitate detailed auditing and incident response.
• Organize rule-based network share access to enforce security policies effectively and prevent unauthorized access, based on system and user context.
• Ensure high system performance and reliability whilst operating at kernel level, minimizing latency and resource overhead.

• Kernel-mode file system filtering to intercept file activity events with minimal impact on system performance.
• Collection of comprehensive session parameters and user metadata during file access events.
• Real-time logging and storage of file access information for auditing purposes.
• Implementation of rule-based access control for network shares, enabling dynamic policy enforcement based on file, user, and session attributes.
• Internally utilize Windows API research and best practices to ensure compatibility and stability within the Windows kernel environment.

• Windows security and user session management APIs
• Centralized logging and auditing infrastructure
• Policy management systems for rule definition and enforcement

• High performance with minimal system overhead, targeting sub-50ms latency for file access monitoring.
• Robust security features to prevent driver exploits or system compromise.
• High availability and reliability to support continuous monitoring without downtime.
• Scalability to handle monitoring over thousands of network shares and users.

The implementation of this kernel-level file activity monitoring and rule-based access control system is expected to significantly enhance the organization's security posture by providing detailed, real-time insights into file access activities. This will enable more effective threat detection, incident response, and policy enforcement, potentially reducing unauthorized access incidents and improving compliance verification. The solution aims to operate efficiently within the kernel environment, ensuring minimal latency and system impact.
