Problems solved by technology

Firewalls and anti-virus software mostly passively detect network attacks and virus behaviors, and do not pay much attention to the security of the Linux operating system itself. For example, when the system dynamic link library is attacked, most traditional security protection software cannot effectively protect

Embodiment 1

[0046]Embodiment 1 of the present invention provides a system and method for protecting the security of a Linux operating system based on IMA. Such as figure 1 Shown is a system architecture diagram for protecting the security of a Linux operating system based on IMA in Embodiment 1 of the present invention. The system includes a safety management center node unit and a protected node unit.

[0047] The security management center node unit is used for unified policy configuration and security status judgment, and mainly includes a security policy configuration module, a benchmark value collection module and a security status judgment module.

[0048] The security policy configuration module is responsible for security configuration and delivery, and is used to deliver basic files to the protected node node unit. At the same time, set the working mode of the safety management center node unit; the working mode of the safety management center node unit is divided into two type...

Abstract

A system and method for protecting security of Linux operating system base on IMA. At first, that node unit of the security management cent configures a protection policy to the protect node unit, Asthat system executable file, system dynamic link library, System configuration files on the protected node unit need to be run and loaded into the Linux operating system, A measure value of that protected node element is obtain by measuring the object using an IMA technology, and then reporting the measure value to the node unit of the security management center. At last, after that node unit of the security management center analyze and confirms the identity information of the protected node unit, whether the upload metric value is the same as the reference value collected beforehand is compared to judge whether the protected object is tampered with or not, so as to protect the security of the Linux operating system on the protected node unit. The invention protects the integrity of the Linux operating system core system file, enhances the security of the Linux operating system, and the protection cycle will accompany the whole operating system running phase.

Description

technical field [0001] The invention relates to the field of Linux operating system security, and relates to a system and method for protecting the security of a Linux operating system based on IMA. Background technique [0002] With the development of computer technology and the popularization of network applications, people pay more and more attention to information security. The computer operating system is not only the basis for the operation of various applications, but also the carrier of various applications. At present, the security of the Linux operating system is mainly protected by firewalls and antivirus software. Firewalls mainly prevent network attacks and network penetration, and antivirus software mainly relies on virus databases and virus behavior characteristics for alarm and interception. Firewalls and antivirus software mostly passively detect network attacks and virus behaviors, and do not pay much attention to the security of the Linux operating syste...
