Recently, the Russian Foreign Ministry said that a series of evidence showed that western countries intervened to destroy the eighth Russian State Duma election by means of network information infiltration. Russia released the data of attacks in cyberspace, accused Western countries of shouting to catch thieves on the issue of network security, and warned them to give up this action immediately, otherwise Russia will fight back in its own way. Russian officers and soldiers conducted anti hacker attacks Publish network security status According to the data of the information security center of Russia's national defense command center, Russian citizens and government institutions have been attacked or invaded by overseas networks year by year in recent years. Russian media said that Western intelligence agencies continue to try to hunt Russian Defense and economic intelligence. After Crimea's entry into Russia in 2014, the United States and other western countries launched comprehensive sanctions against Russia, bilateral relations deteriorated sharply, and multi field exchanges were frequent. Cyberspace has become an important field for western countries to attack Russia by using technological hegemony. Russia pointed out in the new version of the national security strategy that in the past five years, external forces have carried out anti Russian actions with the help of the Internet, such as multinational telecom operators pushing distorted historical information to users in Russia through the Internet platform; On the eve of major festivals, the United States, Britain and other countries incited the anti Russian public opinion storm through the Internet. In the second half of 2020, NATO tried to incite a new round of color revolution in Belarus through the voice advantage of the Internet, which was regarded as a new western anti Russian trick. According to the statistics released by Russia's national computer accident coordination center, since 2018, Russia's key infrastructure has suffered more than 17.2 billion cyber attacks, and the Russian government, the Ministry of defense, economic departments and national strategic facilities have become the main targets of western countries. In 2019, the Russian state grid was attacked by trojan virus from the West. In 2020, Kaspersky laboratory encountered a large-scale network siege. In 2021, the website of a network research institution under the Ministry of defense was paralyzed by foreign intrusion. Patrushev, Secretary of the Security Council of the Russian Federation, said that unfriendly acts such as network infiltration by western countries pose a serious threat to Russia's national security. In addition, some Russian institutions have long used foreign information technology equipment, resulting in high security risks for key information infrastructure. Comprehensively improve coping ability In order to cope with the increasingly severe network security threats, Russia is comprehensively improving its response capacity, accelerating the construction of national network attack and defense capacity, and giving priority to network security in the financial and national defense fields. In the new version of the national security strategy, Russia assessed the current network security threat sources, including foreign targeted network attacks on Russian information resources, foreign intelligence agencies using the network to steal Russian information, external forces publishing terrorism and violence related information through the Internet and undermining Russian social stability. The federal security agency establishes an early warning, identification, traceability and consequence elimination mechanism for cyber attacks against Russian national information resources and embassies and consulates abroad, sends information about cyber attacks to relevant departments at the first time and summarizes it to the national computer accident coordination center, and uses professional forces to properly deal with threats. At the military level, on the one hand, the Russian army adheres to the principle of physical isolation and creates a military exclusive Internet. Important and sensitive information of the military and military enterprises is only used on the intranet. The Russian Ministry of defense will complete the multi-functional service communication transmission network project by the end of this year, and lay an exclusive optical fiber network across the Arctic seabed. The information transmission reliability is high, which can ensure the stable operation in wartime. On the other hand, the Russian Ministry of defense established a network special force under the intelligence bureau of the general staff to be responsible for the operation and maintenance of the military Internet, and to find and deal with network threat targets. The army has extremely high requirements for personnel loyalty and professional standards, and the selection conditions are harsh. All personnel are composed of professional and technical officers with high ranks. Russian media disclosed that the Russian army has a series of network weapons such as botnets and traceability tools, and has both reconnaissance, attack and defense capabilities. It is an important force for the Russian army to carry out strategic counterattack in this field. Russia attaches great importance to technical protection and builds multiple "firewalls" for the national Internet. At present, Russia is promoting the full use of domestic network equipment by government and other offices, preventing opponents from reserving back doors, and giving priority to the use of Chinese and German technology when domestic technology cannot meet practical needs. In accordance with the Russian sovereign Internet law, Russia has also established an internal and external hierarchical management mechanism, that is, the establishment of network user area and management area. After mastering the source of threat, the technicians in the management area can cut off the contact between the two levels to ensure the normal operation of the management area. In addition, under special conditions, Russia will also take the extreme measure of network disconnection. Russia has carried out at least two national network disconnection exercises. During the exercise, Russia derailed the international Internet with military and civil networks in different ways. Relying on the closed data transmission section of the internal network built in 2016, the army and the government implement information and data interaction; Commercial and civil networks use Russian mirror server technology and take domestic routers as data nodes to realize internal circulation, so as to ensure the normal operation of Internet resources in Russia when foreign servers cannot be connected. New battlefield of game between Russia and the West With the intensification of the game between Russia and the west, the collision between the two sides in cyberspace is becoming more and more intense. It is reported that Russia's defensive deployment in cyberspace has aroused concerns in western countries. The United States accused Russia of strengthening the construction of network army under the guise of security threat, and finally formed a huge network destruction capability. European media hype that Russia's strengthening of Internet control aims to establish a security barrier for its autocratic rule. The U.S. military praises Russia's Internet defense behavior and believes that Russia needs to spend nearly 200 billion rubles (1 ruble about 0.09 yuan) to establish a new Internet Exchange Center, which will drag down the process of Russian military modernization. In response to Western doubts, Russia said that more than 60% of the Russian people support the government's network security measures, and Russia has completed self-development of products including computer operating systems, chips and bank payment systems under Western sanctions. Meanwhile, in order to build an independent Internet, the government will subsidize 134 billion rubles for communication operators every year. (outlook new era)
