Safety protection method for ubiquitous power Internet of Things terminal in specific attack scene

Abstract

A safety protection method for a ubiquitous power Internet of Things terminal in a specific attack scene comprises the steps: firstly, forming a sensor network by combining a high-speed transmission technology with sensors, and collecting and uploading information such as temperature and humidity; secondly, preprocessing the acquired information; analyzing a data packet layer by layer to extract amessage instruction-level field, and detecting abnormal data; then, analyzing two attack scenes of a distributed denial service attack and a data tampering attack, associating abnormal events generated by the attacks, finding potential threats in time, and recognizing the attack scenes effectively; and finally, isolating and blocking the attacked terminal by using a power terminal attack blockingand isolating technology, so that the security of the ubiquitous power Internet of Things terminal is ensured. According to the method, specific attack scenes such as distributed denial of service attacks and distributed data tampering attacks which may be suffered can be effectively identified, measures such as blocking and isolation are taken to ensure the network security of the power terminal, and the method has relatively high engineering practical value.

Description

Technical field [0001] The invention belongs to the field of power information security, and specifically relates to a security protection method for a ubiquitous power Internet of Things terminal in a specific attack scenario. Background technique [0002] In 2019, the State Grid Corporation of China proposed to build a ubiquitous power Internet of Things, which is considered to be the key to building an energy Internet. The construction of the energy internet is inseparable from the support of data. The future energy interconnection emphasizes the integration of energy flow and data flow. The ubiquitous power Internet of Things requires massive amounts of electric power data as its development basis, collecting and analyzing the above-mentioned massive edge data, and realizing the interconnection and intercommunication of all links of the power system. In the face of massive amounts of power data, data security is particularly important. Once a network attack occurs, the grid ...
