The system of claim 2, wherein the centralized control module reorganizes the control layer against the functional elements of the various types of security resources, manages them uniformly, and adapts them to external interfaces for the application management module; the centralized control module consists of a resource scheduling engine, a control management module and a control interface decoupled from the security resources; the resource scheduling engine is used for judging, distributing and scheduling whether the current system resource can start the functional element, whether the current functional element is occupied or not and whether deadlock occurs or not, and the starting aspect adopts an FIFO mode to ensure the operating environments of a container and software; the control management module is responsible for pairing and managing 'control-function pair', managing the resource access authority, acquiring information of the state of the function element and feeding the information back to the resource scheduling engine in time; and aiming at the functional elements of the safety resource module, a resource scheduling engine in charge of dynamic allocation and a control management module in charge of resource management and control schedule the functional elements.
4. The system of claim 3, wherein the application management module accepts an external interface provided by the centralized control module, the application management module includes a security service interface and a security application interface for standardizing the interface format, a resource management interface for modifying and querying security resources, and an orchestration engine task issuing interface for processing security tasks, and provides these simplified and centralized security function solutions to users, and users can directly use these services to execute required services or use the orchestration engine application to issue orchestration tasks.
5. The system of claim 4, wherein the centralized management module directly interacting with the secure resources further splits the control layer against the functions based on the secure function elements, corresponds the control layer to the secure function elements to form functional unitized control elements, converges to form control elements in units of single functions by taking 10 categories of secure functions as branches, and constructs the control elements as control interfaces, and the centralized control module provides the control interfaces with minimized functions for the application management module to use.
6. The system of claim 5, wherein the control management module is further configured to configure the service chaining module to manage the source and allocation of each functional element in processing the input, including which secure resource the data stream is allocated to process, and the processing manner is forwarding traffic or copying traffic.
7. The system of claim 6, wherein the resource scheduling engine determines the resources expected to be consumed by the security resources by: the following definitions are first made: resource overhead
Refers to the resource overhead incurred by deploying a functional element i to a virtual resource r,
represents the storage overhead of the selected virtual resource r;
an overhead of computing resources representing the selected virtual resource r;
representing the interaction overhead generated by deploying the functional element i on the virtual resource r and a resource scheduling engine;
the data transmission quantity between the function module representing the function element and the resource scheduling engine;
thus, there are:
resource scheduling engine pair
And judging, when the distributable resources do not meet the conditions, waiting for resource distribution and execution in an FIFO mode, detecting the deadlock problem of the function element resource request in real time by the centralized management module, checking the running state of the safety resources, and carrying out proper adjustment and distribution.
