The Operating System Registry
To Review the security over system and program control parameters in the operating system registry:
1. Review the operating system directory and file permissions over system and program control parameters in the operating system registry.
2. View the registry permission for the major system and program keys and sub keys to ensure the following:
a. The administrators’ local group owns each key.
b. The owner group and system global group have full access permissions.
c. The global group called everyone, has restricted special access permissions.
