The following steps have been done as part of server hardening.
1. Secured DNS server.
2. Secured php by disabling dangerous php functions.
3. Installed and configured - Config Server Firewall. Please provide us your IP address so that we can white-list the same in the firewall.
4. Enabled Login Failure Daemon.
5. Disabled unwanted services.
6. Enabled Shell Fork Bomb Protection
7. FTP Hardening : Disable anonymous ftp and root ftp in this server.
8. TMP directory hardening.
9. Enable SSH alerts.
10. Updated all server software's.
Hello <Customer>,
We have completed the following tasks for your Managed server.
Server hardening
Added your server to our monitoring system
As a part of Server hardening, we have performed the following tasks
1. Secured the DNS server.
2. Secured PHP by disabling dangerous php functions.
3. Configured Config Server Firewall
4. Enable Login Failure Daemon
5. Disable unwanted services
6. Enabled Shell Fork Bomb Protection
7. FTP Hardening : Disable anonymous ftp and root ftp in this server
8. TMP directory hardening
9. Enabled SSH alerts
10. Updated all server software's
11. Disabled ping request to your server
12. Installed MOD_EVASIVE
13. Disabled direct root access to the server and created a wheel user for ssh access
14. Changed the default SSH port to 1243
15. Installed ClamAV and scheduled to scan the server on weekly basis for malicious files
16. Installed Netdata to monitor the server performance
Please use the following details to access the server.
<specify the login details - Use SF code option to highlight the login details>
Kindly update us with your public IP address or IP range so we can whitelist the same on the server.
Backup configuration:
---------------------
As part of the managed service we normally configure the backup depending on the disk space. If the disk space is more than 80 GB we will use the below settings:
Daily once, Weekly once, and Monthly once
However, in the case of disk space below 60GB, the backup retention be like:
Weekly once.
All these backup files are stored on the same server. It is not a recommended method to store backups as in case of disk failure or due to some unforseen situation, if the data is lost, we can't restore the website content. We always recommend our customers to maintain the backups remotely.
Important note:
---------------
To monitor your servers continuously, please notify us if you are changing the root password or SSH port
We've whitelisted the below given Support IP addresses. Please don't remove them from the server firewall
115.110.127.198
