数据访问控制方法

By loading a security program at the operating system kernel level and using file and process hooks to generate a global linked list, the relationship between processes and security domains is recorded in real time. This solves the problems of unreasonable permission allocation and cross-scenario violations in data access control under diverse scenarios, and achieves refined management and security improvement of data access.

AI Technical Summary

Technical Problem

In existing technologies, data access control is difficult to adapt to diverse application scenarios, resulting in unreasonable permission allocation, cross-scenario access violations, and increased risk of data leakage.

Method used

By loading a security program at the operating system kernel level, a global linked list is generated using file open hooks and process exit hooks. The process ID and security domain relationship are recorded in real time. The relative path and device ID are combined to determine whether a file belongs to a security domain and to execute the preset access control policy.

Benefits of technology

It enables data access control in multiple scenarios, reduces unreasonable permission allocation and cross-scenario access violations, lowers the risk of data leakage, and ensures data security.

Abstract

本发明公开了一种数据访问控制方法,包括:将预先编辑的安全程序加载至操作系统;注册文件打开钩子与进程退出钩子,并生成全局链表;向文件打开钩子发送文件访问请求;在本地存储场景下,获取本地存储目标文件的相对路径与本地存储在宿主机上的挂载点,拼接形成目标文件的完整路径,根据完整路径判断访问是否属于安全域;在分布式存储场景下,获取目标文件的设备编号与索引节点编号,根据父目录判断访问是否属于安全域;根据判断结果执行预设的访问控制策略;在访问进程退出时,清理对应的进程记录。本申请的技术方案能够满足多场景下数据访问控制,减少权限分配不合理、跨场景访问违规的问题,降低数据泄露的安全风险。
