New Cloud VDS Initial Setup and Security Checklist

Before deploying an application on a new Cloud VDS, complete the basic security and operating system checks.

Verify and update

hostnamectl\nfree -h\ndf -h\napt update && apt upgrade -y

Create an administrator

Create a sudo-enabled user and test a second SSH session before closing root access.

Configure the firewall

Allow SSH first, then open only required application ports such as 80 and 443.

Backups and monitoring

Monitor CPU, memory, disk and services. Use snapshots before risky changes and maintain independent file and database backups.
