Hong Kong lightweight cloud server is suitable for lightweight business scenarios, and its security is generally very high. When using, on the one hand, because the user installs the required environment, system, panel, etc., there is no problem such as security holes due to old versions. On the other hand, Hong Kong lightweight cloud server, like other cloud products, backs up your data to the cloud, and even in the worst case, cloud backup can save your data. In addition, reliable lightweight cloud service providers usually take many measures to ensure the security of user applications and data.

How to protect Hong Kong lightweight cloud server?

encrypted communication

When connecting to your lightweight cloud server, all traffic will go over the public network unless you take steps to secure your communications. Avoid using any unencrypted transmission protocol, or any protocol that sends passwords or other sensitive information in plain text. Instead, you should use SSH (Secure Shell), SCP (Secure Copy), SFTP (SSH File Transfer Protocol), or rsync for all your remote control and file transfer needs.

User Account Security Policy

After first logging into a newly deployed lightweight cloud server, creating a new user account for yourself and enabling sudo access control are some important tasks. Sudo stands for "Super User Execute" and allows you to do things that would otherwise require a root account. This allows you to avoid logging in as root every day and instead use sudo privileges to execute root-level commands when needed. Using sudo is considered a good practice for security and it is usually installed by default in most Linux distributions. Take full advantage of what sudo has to offer and set up secure user access.

Monitor login authentication

The reality of today's Internet is that sooner or later your lightweight cloud server security will be tested by a malicious party, hoping to find an insecure entry point. If your lightweight cloud server has been running for a day, you have most likely experienced failed login attempts from IP addresses other than your own. Most Linux distributions keep logs for authentication when first booting.

Set up the firewall

A common solution to the security of any networked computer is to set limits on allowed connections. This can be done by using a firewall (a network security system), based on the powerful security rules of the firewall, all incoming and outgoing network traffic of the cloud server will be monitored and controlled.

update your system

Make sure to regularly check for updates on the lightweight cloud server. From time to time new vulnerabilities are discovered and usually patched quickly. Make sure your lightweight cloud server has the |latest |fixes to keep your |system up-to-date and secure.

Minimize Vulnerabilities

An important part of securing a lightweight cloud server is not to open any unnecessary network services that are listening|listening for incoming connections. Newly deployed lightweight cloud Linux systems usually only have SSH port 22 open. You can test your own server by using a network tool to scan for open ports.

Also, pay close attention to any other services that are open to the public network. Make sure you know which services you are running and how secure their connection method is. Disable any services you know you don't need.

Regularly scan for malware

The primary defense is preventative work to block unauthorized access, but it cannot be your only security measure. While you might think that there is nothing unusual on your system, unwanted programs can run unnoticed for a long time before causing alarm traffic or system damage. Therefore, it is very important to regularly scan your cloud server for malware, just to make sure it is not infected.

Implement an intrusion detection system

Checking your system with a malware scanner etc. is still a major scheduled task that is performed from time to time. This gives any malware time to do their business between scans, potentially going unnoticed, even for long periods of time. The solution to downtime between malware scans is to have an intrusion detection system (IDS) that keeps an eye on the lightweight cloud server and its network traffic.
