    • The present invention discloses an apparatus and a method for forming a protective layer around computer memory that allows access to specified external locations and applications only. A routine seeking access to the computer memory must be cleared for access by at least two different permission checking algorithms that work in conjunction to a database to determine whether access should be allowed. The invention protects the hard drive from unauthorized reading and writing by verifying permission definitions from a hard drive database and monitors startup files for changes from previous versions to prevent unauthorized control of the computer recourses at the outset of its operation upon power up. Additionally, the present invention will protect from unauthorized TCP/IP connections by verifying permissions from a TCP/IP permissions database.
    • 本发明公开了一种用于在计算机存储器周围形成保护层的装置和方法,其仅允许访问指定的外部位置和应用。 必须清除寻求访问计算机内存的常规,以便至少两个不同的权限检查算法进行访问,这些算法与数据库结合使用,以确定是否应允许访问。 本发明通过验证来自硬盘驱动器数据库的许可定义来保护硬盘驱动器免受未经授权的读取和写入,并且监视来自先前版本的更改的启动文件,以防止在上电时其操作开始时对计算机资源的未经授权的控制。 此外,本发明将通过验证来自TCP / IP许可数据库的许可来防止未授权的TCP / IP连接。
