4. Corporate Defense and Attack Exercise： Email Phishing Practice

With the development of Internet technology and the increasing level of enterprise informatization, enterprises are facing more and more network security threats.To protect corporate information security, offensive and defensive exercises have become an indispensable part of corporate security operations.Attackers often use various methods to disrupt corporate security systems and data. Therefore, enterprises need to think like attackers, find and strengthen the weakest links, and build a more complete and reliable security system. By conducting attacks, enterprises can discover security vulnerabilities, formulate effective security strategies, enhance emergency response mechanisms, and thus better ensure the safety and stability of their operations.

1. What are attack and defense drills

Attack and defense drills (Red Team/Blue Team Exercise) are simulations of real attacks and defenses. By conducting attack tests and security drills on networks, systems, and applications, they assess the information security defense capabilities of enterprises or organizations, identify potential security risks and vulnerabilities, and improve the organization's ability to respond to security threats.

Attack and defense drills are generally divided into two roles: the red team (attackers) and the blue team (defenders).The red team simulates external attackers trying to infiltrate the target system, network, or application, while the blue team is the enterprise defender, taking measures to protect the operating environment of the enterprise system. This simulation aims to enable enterprises or organizations to better understand their security, identify and correct potential problems, and improve their security and reduce risks, while also helping to improve the skills and response capabilities of team members.

Red and blue attack and defense allow both sides to attack and defend in simulated environments, providing a practical way to improve offensive and defensive skills to respond to modern network security risks and threats; by evaluating the performance of the defense side, it improves the effectiveness of security defense strategies and measures.

2. What benefits can attack and defense drills bring to enterprises

In the attack and defense simulation, the red team will attempt to exploit vulnerabilities in the system to obtain sensitive data or access permissions, while the blue team will use various security technologies to detect, respond to, and defend against attacks. This helps to strengthen the safety awareness and practical training of the blue team, test the effectiveness of their security defense strategies and measures, and ensure that their network and data are protected to the maximum extent. Additionally,The benefits of attack and defense drills include but are not limited to:

1. Discover security risks:By simulating real attack and defense scenarios, it is possible to discover security vulnerabilities, loopholes, and weaknesses in an enterprise's information system, and timely repair and improve them.

2. Improve safety awareness:Attack and defense drills can enable employees to feel the security threats firsthand, deepen their understanding of security issues, and improve their safety awareness and prevention awareness.

3. Enhance response capabilities:Through continuous practice, enterprises can improve their ability and level to respond to emergencies, effectively prevent and respond to various security threats and attacks.

4. Evaluate security strategies:Attack and defense drills can test the actual effectiveness of an enterprise's security strategies and measures, evaluate their completeness and effectiveness, and provide data support for security decision-making.

5. Improve cooperation efficiency:Attack and defense drills usually require the cooperation of multiple departments or individuals, which helps to strengthen the team's collaboration and communication skills, and improve overall efficiency.

3. How should enterprises carry out attack and defense drills

Before an enterprise organizes an attack and defense drill, it shouldAfter obtaining the consent of the relevant departments, formulate detailed security strategies and operational specifications to ensure the smooth progress of the drill.At the same time, considering the actual operating environment of the system, fully taking into account the possible risks and impacts of the drill, and taking necessary security measures to ensure the safety and controllability of the drill process. The general steps for enterprises to carry out attack and defense drills are as follows:

1. Determine the Target:Define the purpose, scope, and participants of the exercise, determine the attack plan and defense measures.

2. Simulation Attack:Use legitimate tools and technologies to simulate attack behavior, such as network penetration testing, social engineering, etc.

3. Monitoring Response:Monitor system logs and alarm information to assess the ability to detect and respond to security incidents.

4. Exercise Summary:Summarize and analyze the exercise process, identify problems, and improve defense strategies and measures.

5. Security Awareness Training:Strengthen employees' security awareness and emergency response capabilities through exercises.

6. Regular Updates:Regularly update defense and attack exercise plans and content, and track the latest threat intelligence and security technologies.

When conducting defense and attack exercises, enterprises should focus on key points based on their own systems, personnel, and environmental factors.For example, when the external system has a low degree of openness, there are many internal systems, and corporate personnel heavily rely on external communication tools for communication and collaborative office work, enterprises should focus on simulating attacks on personnel safety during defense and attack exercises to ensure the safety of corporate personnel, thereby ensuring the security of the internal systems of the enterprise.

4. Corporate Defense and Attack Exercise: Email Phishing Practice

The importance of network security lies in humans.Because humans are the weakest link in information systems. Many security incidents are caused by human negligence, misoperation, or deception by attackers. Therefore, improving the security awareness and preventive capabilities of personnel is crucial for ensuring corporate information security.

Security awareness training is an effective way to improve employees' security awareness and preventive capabilities.Practice can be carried out through means such as email phishing. Email phishing is a common social engineering attack method, where attackers send lure emails disguised as normal emails to deceive recipients into providing sensitive information or executing malicious operations. Enterprises can simulate attacks using email phishing to test the reactions and behaviors of employees, and carry out targeted security training and exercises to improve employees' security awareness and response capabilities.

The following content needs to be prepared in advance in the practice of corporate email phishing:

1. Determine the Target:Identify the target of the attack, such as the security awareness of specific personnel or departments.

2. Lure Emails:Create lure emails disguised as legitimate corporate emails, including titles, body, and attachments, and inject malicious code or links so that attackers can obtain sensitive information or control the system.

3. Dummy List or Dummy Website:If it is necessary to collect sensitive information such as user accounts and passwords, then a dummy list or dummy website needs to be prepared so that attackers can input the victim's information into it.

4. Monitoring or Control Tools:If it is necessary to monitor the behavior and response of the victim, then professional tracking tools need to be used. If it is necessary to control the victim's compromised machine, then remote control tools need to be used in conjunction.

When conducting corporate email phishing practices, it should be noted that: comply with laws and moral norms, do not steal or abuse others' information, and obtain approval from relevant departments before testing, and formulate detailed operational steps and confidentiality measures to ensure the legality and safety of the operation.
