Research on Countermeasures of Cyber Attacks

With the rapid development of information technology, cyberspace has become an indispensable and important component in production, learning, entertainment, social interaction, etc., and has also become an important part of all walks of life. Work platform. However, network attacks are also developing simultaneously. More and more people are attacking networks and information systems, and they are becoming more and more skilled, which has brought huge challenges to network space security. This has also made network security a concern of today's society. One of the hot topics. This article will discuss countermeasures against cyberattacks in order to improve network security.

1. Understand the types of network attacks

Before formulating network security countermeasures, we need to understand the types of network attacks, which can help us better resist network attacks.

  1. Malware: including viruses, worms, Trojans and other malware that can implant themselves into the user's system without the user's consent.
  2. E-mail fraud: defrauding users of relevant information, passwords or bank card information to obtain benefits.
  3. Website deception: defrauding user information by building fake websites, imitating real websites and deceiving links.
  4. Phishing: Sending false emails or messages to trick users into clicking on links or entering account information.
  5. Remote attack: Invade other computers and use their resources such as bandwidth and capacity to carry out attacks.

2. Strengthen the system

  1. Install anti-virus software: Anti-virus software can promptly detect and eliminate the intrusion of viruses, Trojans and other malicious programs to ensure the security of system information.
  2. Confirm the source of the software: Only download and install software from official websites and authorized sales points to avoid unnecessary risks caused by downloading software from other sources.
  3. Disable file sharing: Turn off the file sharing function to avoid unnecessary risks.
  4. Strengthen password management: It is recommended to use complex passwords, and do not log in and handle confidential data on unsecured networks.
  5. Update anti-virus software and system patches in a timely manner: Update security software and system patches regularly, and patch security vulnerabilities in a timely manner.

3. Pay attention to information security management

  1. Ensure the backup of information and data: Back up information and data in a timely manner to prevent data loss or loss.
  2. Restrict user permissions: Restricting user permissions and assigning reasonable permissions to each user can prevent malicious attackers from gaining complete control of the system through some small attacks.
  3. Establish user behavioral norms: Establish good user behavioral norms and establish users' security awareness and safety habits.
  4. Improve employees’ security awareness: Strengthen employee network security training and improve employees’ security awareness.

4. Strengthen network monitoring and emergency measures

  1. Install a firewall: Install a firewall to protect network security, manage outbound traffic, inbound traffic, protocol stacks, and applications , operating system, etc. to prevent malicious attacks from entering the system.
  2. Carry out vulnerability scans: Conduct vulnerability scans regularly to discover potential vulnerabilities in the system and patch them in a timely manner.
  3. Carry out intrusion detection: Establish an intrusion detection system to detect suspicious events in time and increase the security of the system.
  4. Establish an emergency response plan: Establish an emergency response plan to respond to network security issues in a timely manner.

In summary, network security issues are becoming increasingly prominent, and it is particularly important to explore countermeasures against network attacks. Only by comprehensively utilizing technical means and management means to strengthen network security management can we better protect network information security and achieve a safe, fast and convenient online world.
