4 Overview of DCS risk and vulnerability detection
4.1 DCS system overview
4.1.1 Network structure of common DCS system application
DCS system applications are usually a vertical hierarchical network structure, from top to bottom including process monitoring layer, field control layer and field equipment layer. Each layer is connected by a communication network, and each equipment in each layer is communicated through a communication network of the same level. The typical network structure is as shown in Figure 1. This part mainly proposes requirements for security requirements of the process monitoring layer, field control layer network, and field equipment layer network in the DCS system. The description of each layer is as follows. - Process monitoring layer. the main task is to monitor the operation, it has some management functions at the same time. This level is for operator
and control system engineers, so it is equipped at this level with
technologically sophisticated computer systems and a wide range of
external devices, especially displays and keyboards, it also requires
support from hard discs or soft discs of large storage capacity as well as the support of software of strong functions, to ensure that engineers and operators configure, monitor and operate the system, implement advanced control policies, diagnostics, and quality assessments of the production process;
- Field control layer. The main functions of the field control layer include. collecting process data, data conversion and processing; monitoring and control of the production process, output of control signals, achieving analog and digital control; I/O card diagnosis; data communication with process monitoring layer;
- Field equipment layer. The main functions of the field equipment layer include. collecting control signals, executing control commands, performing equipment actions in accordance with control signals.
system operation site to perform field observation of personnel actions, technical facilities and physical environments to judge the personnel security awareness, business operation, management procedures, and other security conditions. Test refers to the testing performed by technical tools.
Detection implementation. The main component of the work unit. It is the specific requirements for detection implementation as developed based on the detection purposes and the detection contents, which relates to the specific detection method, detection target, and operation process. In the detection implementation process, use the adverb “shall” to indicate that these processes are mandatory, which must be completed before the detection staff makes conclusions; use the adverb “may” to indicate that these processes are non- mandatory activities, which have no fundamental impact onto the conclusions made by the detection staff, and can be selectively completed by the detection staff based on actual conditions. The detection measures in this part are all important and need to be considered, but it should be based on the actual application of DCS, DCS security requirements of enterprise to determine whether the detection measures are appropriate and to select feasible detection measures.
Result judgment. Describe how the detection staff can determine whether the system under detection meets the testing requirements based on these
detection evidences after the detection staffs have obtained various detection evidences through performing the detection operations. Before giving the detection conclusions of the overall work unit, it shall first give the conclusion of a single detection implementation item. Generally speaking, the conclusion judgment of a single detection implementation item always requires the
subjective judgment of the detection staff, and this detection implementation item is satisfied once the correct and critical evidence is obtained.
4.6 Implementation of DCS risk and vulnerability detection
For DCS systems that have not been deployed and implemented, the DCS risk and vulnerability detection can be selected before the DCS is put into
production and after the security assessment.
For DCS upgraded based on existing DCS or newly added with extension
functions, it is recommended to perform risk and vulnerability detection on the newly added systems before the new and old system joint test. Conduct risk and vulnerability detection on the affected DCS key components and network communication functions in the old and new joint test phase.
For systems in service, risk and vulnerability detection may be selected afte...
