NeoKylin Linux Trusted OS is a domestic high grade security operating system issued by China Standard Software Co., Ltd. in accordance with CMMi5. And NeoKylin Linux Trusted OS follows standard GB17859,GB/T18336,GB/T20272,POSIX,CC,ISO15408.
NeoKylin Linux Trusted OS is self-determination, controlled and high grade security Operating System software,which is based on LSM mechanism of SELinux subsystem framework, provides the privilege management function by Separation of the Three Powers, customized system security according to customers requirement.
NeoKylin Linux Trusted OS prodvides the unified Security Management Centre(SMC),which supports security mode switching, the important data encryption storage,management of privilege users, personal Identification based two-factor certification, the least privilege of process, Type-Based Access Control with role,network safety protection, fine grain Security Auditing, delete the files in security,etc. It takes all-directional system safety protection for subscriber of government and enterprise.

Users could easily build a controllable and reliable platform based on NeoKylin Linux Trusted OS. It could run on x86 (32-bit), x86_64 (64-bit), MIPS processor architectures to to meet the demand for high availability, reliability, and scalability of applications. Applications are involved in high availability cluster and load balancing cluster, virtualization application services, distributed file system. Meanwhile, it is easy to realize the centralized supervision and management.

High grade security OS
- NeoKylin Linux Trusted OS R&D is abided by the international specifications CC and the National Standards GB/T-20272-2006, have obtained the GB/T 20272-2006 certification of The Ministry of Public Secuity of the People’s Republic of China and sale permits licensed.
Unified Security Management Centre(SMC)
- NeoKylin Linux Trusted OS’s Unified Security Management Centre(SMC) provides graphical, integral, flexible, easy-to-use, efficient security management UI for administrator.
- NeoKylin Linux Trusted OS’s security functions:Separation of the Three Powers(not root,is sysadm,secadm,auditadm), two-factor certification, the Mandatory Access Control, data encryption storage,network security, immune commonly various attacking and intrusion means and system vulnerability has been detected,anti-spam and anti- virus,etc.
High strength of Access Control
- NeoKylin Linux Trusted OS provides the Mandatory Access Control(MAC),SeLinux TE(Type Enforcement), RBAC (Role-Based Access Control),Multilevel security(MLS),etc.RBAC(Role-Based Access Control) has reduced the complexity and cost of authorized privilege management effectively,and can provide a more security environment.
- NeoKylin Linux Trusted OS is based on LSM mechanism of SELinux subsystem framework and provides the privilege management function by Separation of the Three (not root,is sysadm,secadm,auditadm).
Security policy flexible setting
- NeoKylin Linux Trusted OS provides multiple Access Control Model based SELinux subsystem framework and multiple graphical management tools, accomplishs dynamic, flexible security policy setting,supports switchback of different security levels and authentication mechanism.
- NeoKylin Linux Trusted OS provides the user with personalized security policy.
Fine grain Process Management
- Process is only given the minimal amount of running privileges they need. The programs only execut specified operation of perform the tasks required.
- NeoKylin Linux Trusted OS provides independent security audit of process level.
Efficiency, scalability and reliability
- Support more space for sockets, cores, threads, and memory
- To realize the optimization of system kernel performance, disk and file I /O performance, system thread performance, and network performance
- Use Completely Fair Schedule(CFS) process scheduling strategy: Fairly scheduled task running according to task time consumption, priority and other factors, in order to greatly optimize task performance and energy consumption
- Default ext4 file system with much performance optimization, maximum file system up to 16TB, and the kernel supports maximum 100TB XFS file system at the same time
- Support NeoKylin HA cluster software products,LifeKeeper,NEC HA,etc provide multi-level protection for business system, and realize intelligent switch according to strategy when the traffic load is too large or abnormal service appears.
Favorable software and hardware compatibility
- NeoKylin Linux Trusted OS is compatible with different kinds of software(e.g.DataBase,MiddleWare and Applications) and supports the leading hardware environments(e.g. X86,Intel X86-64,AMD64,Itanium2,IBM Power series).
Perfect development environment
- Support different programming language such as Java, C, Python, Perl, Ruby, PHP, Tcl / Tk, and Shell.
- Support integrated development environments such as Eclipse, Emacs.
- Support IBM java, Sun java, and integrated openjdk1.6 2.
- GCC 4.4 and glibc 2.12 toolchain.
