Today is the seventh national security education day for all. This year's theme is "strengthen the overall national security concept, feel the achievements of national security in the new era, and create a good atmosphere for the victory of the 20th CPC National Congress". A few days ago, the national security education day activity logo was released. The logo is composed of the number 415, red star and light. It is fan-shaped as a whole, and the text is located below the logo, reflecting the comprehensive strengthening of national security under the leadership of the party and the personal responsibility of "security has me". The picture shows the activity logo of the national security education day for all. On April 14, in Wuxi, Jiangsu Province, the frontier inspection police were promoting the knowledge of national security related laws and regulations to the dock staff. (visual source: China) Safeguarding national security is an invisible modern war. This battlefield is more hidden, more complex and broader than the traditional battlefield in the past. According to the national security law of the people's Republic of China, the "national security education day for all" on April 15 every year is an important node and opportunity to comprehensively strengthen national security publicity and education. Comprehensively improving the awareness and level of national security and consolidating the mass foundation of national security are not only the significance of the national security education day for all, but also the due meaning of safeguarding national security for all. The scope of national security is very wide, including political security, military security, economic security, resource security and many other fields. Guarding such a wide range of security fields is not only the responsibility of a department or industry, but also the common mission of 1.4 billion people. However, in the consciousness of a considerable number of people, national security is only a confidential "tall" thing, which has little to do with itself. The current peaceful and stable social life also makes many people lose their vigilance. From the existing cases, some people do not abide by the confidentiality provisions, resulting in the disclosure of documents, and some people release false statements at will, resulting in adverse effects. These acts may threaten national security. "Cathay Pacific" can "people's safety". National security is not a distant "spy war film", but is closely related to every one of us and every family. At work, we will resolutely keep secrets and do not talk about state secrets or work secrets on wechat, microblog and forums; It is found that someone buys and sells documents and materials belonging to state secrets, that suspicious persons collect information on science and technology, economy and enterprises, and report to the public security organ or national security organ in time... All these are to protect national security with their own practical actions. In safeguarding national security, neither you nor he is an outsider and must not be a bystander. If everyone tightens the string of national security and tightens the "safety valve" in his mind, the whole society can build a great wall of steel to protect national security. (outlook new era)
