What are the security risks of using linux?

Linux security risks and solutions: 1. Weak passwords and unupdated software, use complex passwords, and regularly update and upgrade software; 2. Incorrect user rights management, avoid using the root user for routine Operation; 3. Malware and viruses, use official software sources for software installation, and scan the system regularly; 4. Incorrect network configuration, disable unnecessary services, and use encryption and secure transmission protocols; 5. Insecure sharing and transmission, encrypt sensitive data, and use security protocols; 6. Lack of logging and monitoring, enable appropriate logging functions.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

When using the Linux operating system, although Linux has higher security compared to other operating systems, there are still some potential security risks. Here are some common security risks and suggestions for avoiding them:

1. Weak Passwords and Unupdated Software: Weak passwords can be easily guessed or cracked, while unupdated software may have known loopholes. To avoid these risks, it is highly recommended to use complex passwords and regularly update and upgrade software, including the operating system itself and applications.

2. Incorrect user rights management: Incorrect user rights settings may lead to potential security vulnerabilities. Avoid using the root user for normal operations. Instead, use a normal user account and assign it the appropriate permissions. Use root privileges only when necessary.

3. Malware and Viruses: While Linux is relatively less affected by malware and viruses, you still need to be vigilant. Avoid downloading and installing software from untrusted sources, use official software sources for software installation, and regularly scan your system to detect potential malware.

4. Incorrect network configuration: Incorrect network configuration can lead to unauthorized access and data leakage. Ensure firewalls and network access controls are properly configured, disable unnecessary services, and use encryption and secure transport protocols such as SSH to protect remote access.

5. Insecure sharing and transfer: When sharing and transferring files, make sure to use a secure transfer protocol (such as SFTP or HTTPS) and encrypt sensitive data. Avoid using insecure protocols (such as FTP or HTTP) and transmitting sensitive information in the clear over open networks.

6. Lack of logging and monitoring: Lack of logging and monitoring systems may result in failure to detect security incidents in a timely manner. Be sure to enable appropriate logging capabilities and review logs regularly to detect unusual activity. At the same time, use security monitoring tools to monitor system and network activities in real time to identify and respond to potential security threats in a timely manner.

In addition to the above suggestions, regularly backing up important data, using highly secure software and tools, and paying attention to security updates and recommendations from the Linux community are also important measures to ensure Linux security. In addition, it is also crucial to understand and understand common security threats and attack techniques, and to enhance your own security awareness and knowledge.
