Some Advice for Common Problems
To minimize risks, there are a few things should do.
- If you do not use related service then stop it. Do not increase your attack surface. Stoping unnecessary services is one of the best practices and huge step in hardening operation systems. For example if port 21 open for ftp and you do not using it, stop ftp service.
- You should restrict access. Use either a firewall to allow specific IP addresses for your port if you can or change your service settings to make accessible only from localhost.
- Make sure your softwares are up to date. Do not miss any security patches.
- Use strong password if your services use an authentication mechanism (like ssh, ftp, rdp). Whole internet are scanning by attackers to detect weak passwords.
