Recently, the State Council Information Office held a press conference for Chinese and foreign journalists on the topic of "Strugglers on the New Journey". Advanced and typical representatives of the public security system met and exchanged ideas with Chinese and foreign journalists around the theme of "promoting the spirit of public security heroes and being loyal defenders of the Party and the people". The cyberspace is a shared spiritual home for billions of people. Without cyberspace security, there can be no national security or people's security. ”Zhang Zhiheng, Deputy Captain of the Sixth Brigade of the Network Security Support Team of Lianyungang Public Security Bureau in Jiangsu Province, introduced that since graduating from the police in 2020, he has been engaged in network security work. Over the past five years, he and his colleagues have focused on cracking down on various new types of network crimes such as "hacker attacks", "infringement of citizens' personal information", and "artificial intelligence deep forgery", repeatedly cutting off the source of network crimes and defending the legitimate rights and interests of billions of netizens. Although the online battlefield is not filled with gunfire, every online confrontation with criminals is also full of risks and challenges. Zhang Zhiheng recalled an arrest in 2021, when he and his colleagues faced a group of cunning and ferocious suspect involved in the network. During the arrest process, the behind the scenes gang even sent threatening messages to them, remotely destroying evidence in an attempt to put them in a difficult situation. However, Zhang Zhiheng and his colleagues were not intimidated by these difficulties. They worked tirelessly day and night, shuttling between two provinces and three cities. Finally, on the last day of the Qingming Festival holiday, they captured the core members behind the case who were about to leave the country. Zhang Zhiheng admitted that during his tenure in cybersecurity, he has always demanded that he strive for excellence in two things: first, to hone his ability to be one step ahead of others, to be ahead of others in critical moments, and to take the initiative in the online battlefield; The second is to remain calm in the face of unexpected situations, like a bomb disposal hand dismantling a bomb, to find the "line" and decisively "cut" to prevent risks; At the same time, one should aim at the "point" like a sniper, with a thunderous "gun", sniping at crimes. It is precisely with this spirit of striving for excellence and extraordinary courage and wisdom that he has been able to achieve remarkable results in numerous online battles. Regarding the phenomenon of people receiving harassing phone calls or advertising messages in their daily lives, Zhang Zhiheng told reporters that behind these seemingly simple phone calls may be a high-level and professional cybercrime gang. For cybersecurity police officers, investigating such cases requires two arduous battles with criminals: technical warfare and psychological warfare. Therefore, they must constantly strengthen their professional knowledge reserves and have a firm confidence in "daring to fight and winning" in order to achieve victory in this tough battle of technical and psychological competition. The police model is a hero worthy of respect from the whole society. When it comes to the medal on his chest, Zhang Zhiheng is full of emotions: "The medal is recognition, but also motivation and encouragement. It can only represent the past. As a young police officer, I am just a small microcosm of the cybersecurity front. The road ahead is still long, and I need to learn and consult more from the predecessors of model heroes, and integrate the spirit of model heroes into every moment of work, reflecting in every moment of charging forward." "When the wind comes, it's better to follow it! ”He said that as a young internet police officer in the new era, he will use the mouse as a shield, the keyboard as a sword, and guard the "cloud lights" with loyalty and responsibility.
