4 Description of computer security reinforcement
systems
The computer security reinforcement system is based on the general operating
system. It enhances the security functions of the operating system by marking
the host and object of the operating system, adding mandatory access control,
integrity protection and other technical means, to make up for the security of
the general-purpose operating system, and to improve the security protection
capabilities of the operating system.
development, guidance documents, life cycle support, test, vulnerability
assessment.
5.2 Security grade
According to the strength of the security function requirements of the computer
security reinforcement systems and GB/T 18336.3-2015, divide the security
grade of the computer security reinforcement systems. The security grade is
divided into basic grade and enhanced grade. The strength of security functions
and the level of security assurance requirements are the specific basis for
gradation; the security grade highlights the security feature.
6 Security function requirements
6.1 Authentication
The product's reinforcement requirements for the operating system's identity
authentication function shall meet:
a) The operating system user identification shall use the user name and user
identification (UID), and achieve the unique identification of the user
throughout the life cycle of the operating system, and the consistency
between the user name, UID, etc.;
b) For operating system users, use enhanced password management and/or
token-based dynamic passwords and/or biometric authentication and/or
digital certificates for identity authentication;
c) For operating system users, use the two-factor authentication technology
in 6.1b) to authenticate users.
6.2 Security identification
The product's reinforcement requirements for the operating system security
identification shall meet:
a) Set sensitivity labels on subjects and objects within the control range of
operating system security functions;
b) When information is input from outside the control range of the operating
system to the control range, its sensitivity label shall be marked by a label;
c) Set sensitivity labels on all subjects and objects of the operating system;
d) When information is input from within the control range of the operating
system to outside the control range, the sensitivity label of the data shall
be clearly marked.
e) Provide functions such as termination of illegal processes, simple attack
detection, and measures to prevent audit data loss;
f) Audit records include the date, time, type, subject identification, object
identification and results of the event.
6.5 Integrity protection
The product's reinforcement requirements for the operating system integrity
protection shall meet:
a) Be able to set integrity labels for subjects and objects within the control
range of operating system security functions; establish integrity protection
strategy models; protect the integrity of important files during storage,
transmission and processing;
b) Have measures to recover after detecting that the integrity has been
damaged;
c) Ensure that low-integrity data cannot be inserted or overwritten to high-
integrity data;
d) Ensure that the level of data integrity is not reduced during processing;
e) Establish a semi-formal integrity security policy model.
6.6 Remaining information protection
The product's reinforcement requirements for the operating system remaining
information protection shall meet:
a) Ensure that the storage space where the authentication information of
operating system users is located is completely cleared before being
released or redistributed to other users, regardless of whether the
information is stored on the hard disk or in the memory;
b) Ensure that the storage space where resources such as files and
directories in the system are located is completely cleared before being
released or reallocated to other users.
6.7 Administrator security management
6.7.1 Initialization of administrator properties
The product shall provide the ability to initialize the attributes of the authorized
administrator.
6.7.2 The unique identifier of the administrator
It shall protect the data that is transmitted through the network between product
components, so as to prevent unauthorized access.
6.9 Audit log management
The product shall provide the following functions to manage audit logs:
a) Perform a combined query of audit logs according to date, time, user
identification, application resource identification and other conditions;
b) There are certain measures to prevent the loss of audit logs;
c) Back up the audit log and clear it after backup.
7 Security assurance requirements
