Attack and defense exercises are a type of practical cybersecurity testing service that aims to improve the ability of enterprises to respond to cyber attacks and enhance the overall level of cybersecurity protection.

During the exercise, attackers (red team) and defender (blue team) will be formed to simulate a real online confrontation scenario. The Red Team is composed of professional security experts. They simulate hackers' attack methods and use various tools and techniques to launch all-round infiltration attacks on target systems. From scanning common network ports to complex exploits, and even using social engineering techniques to try to break through an enterprise's cyber defenses and obtain sensitive information or control critical systems.

As the guardians of the enterprise, the Blue Team bears the heavy responsibility of ensuring system security. They relied on the company's existing security protection system to detect Red Team's attacks in a timely manner by monitoring network traffic in real time and analyzing security logs. Once an attack is detected, the Blue Team quickly takes defensive measures, such as urgently fixing system vulnerabilities, blocking malicious network connections, and restoring affected data, etc., to fully protect the security of the enterprise's information assets.

The entire rehearsal process was supervised and controlled by a neutral referee (white team). The white team notarized the entire exercise according to pre-determined rules to ensure the fairness and safety of the exercise. After the drill was completed, the White team conducted a comprehensive evaluation of the performance of both parties. From the effectiveness of the attack and the speed of defensive response to the discovery and repair of the vulnerability, the drill data was analyzed in a comprehensive manner, the lessons learned, and made targeted improvement suggestions for the enterprise.

By participating in attack and defense exercises, enterprises can detect weak points in their own network security protection in advance and fix potential security breaches in a timely manner. At the same time, it effectively enhances the security team's emergency response capabilities and collaborative combat capabilities, so that the team can respond quickly and accurately when faced with real cyber attacks. In addition, offensive and defensive drills can also help enterprises improve cybersecurity strategies and emergency response mechanisms, and build a solid security barrier for the digital transformation of enterprises.
