After renting a Hong Kong cloud server for delivery, it is very important to ensure the security settings of the server. Here are some suggestions that can help you make cloud server security settings:

Update the operating system and software

Regularly update the server's operating system, applications, and software, including security patches and updated versions, to fix known security vulnerabilities and ensure that the server remains up-to-date and secure.

configure firewall

Set up a firewall to limit the communication between the server and the external network, and only allow necessary network traffic to enter and exit the server. It can be configured using the built-in firewall of the operating system or the network security group of the cloud service provider.

Use strong authentication methods: Disable default accounts and passwords, use complex passwords, and enable multi-factor authentication (MFA) to increase the security of logging into the server. Avoid using shared accounts and passwords, each user should have an independent account, and set appropriate permissions as needed.

Back up data regularly

Regularly back up the data on the server and store the backups in a safe place to prevent data loss or malicious attacks. You can use the backup service of a cloud service provider or set up a data backup strategy by yourself.

Restrict network access

Allow only necessary network access and restrict remote access to the server. Remote access can be done using a web proxy or a secure remote desktop protocol such as SSH, and restrict access to only authorized users and IP addresses.

Monitoring and logging

Set server monitoring and logging, including login records, system logs, and application logs, so as to detect and deal with potential security threats in a timely manner.

Install security software

Install and configure security software, such as anti-virus software, intrusion detection system (IDS), security audit tools, etc., to provide additional security protection.

Regularly review permissions and access

Periodically review user permissions and access on the server, and promptly disable or delete user accounts and permissions that are no longer needed to reduce potential security risks.

The above are some common cloud server security setting suggestions, and the specific settings and configurations may vary according to your business needs and security policies. It is recommended that you regularly review and update your server's security settings in accordance with best practices and security standards to ensure server security and stability.
