[Retracted] Security and Privacy Risk Assessment of Energy Big Data in Cloud Environment

Table 1

Risk assessment level.

Risk level	Meaning
First class (0 ≤ R ≤ 0.2)	The risk level is very low, so it is not necessary to pay special attention to it. The plan and general prevention can be made.
Second class (0.2 < R ≤ 0.4)	The risk level is low, the plan and general prevention should be made, and need to be checked regularly.
Third class (0.4 < R ≤ 0.6)	The risk level is medium; the major risk factors should be paid attention to in combination with the specific situation, and the corresponding countermeasures should be formulated.
Fourth class (0.6 < R ≤ 0.8)	The risk level is high; it is necessary to pay attention to all the risk factors that may threaten the security of energy data, formulate the process sequence after the occurrence of the risk according to the importance degree, and track the inspection and evaluation.
Fifth class (0.8 < R ≤ 1.0)	The risk level is very high; if necessary, it can be stopped and maintained, and the comprehensive inspection and special evaluation should be carried out immediately and can be continued after improvement.
