In this article we will touch upon a topic that is probably familiar to every computer user, namely, the security of operating servers located on VPS hosting .
Unfortunately, it happens that a user can invest quite a lot of money in the creation and development of a virtual project, its placement and debugging on a virtual dedicated server. But, at some point, the following situation appears before you - the device allocated to you has been hacked. No one is protected from such moments, so do not despair, since the reasons for hacking are different.
But before you try to take content writing service any steps to restore the server, you need to consider the signs of hacking.
What are the signs that a VPS server is hacked?
Poor performance or blocking of the VDS server;
There is no way to use or access root or user rights;
Server traffic increases significantly;
There are traces of spam distribution on the VDS;
Strange activity on the VPS server. This point is worth dwelling on, as unnatural activity is a common cause of hacking. Suspicious activity may include sending emails while you are away or transmitting data via a network protocol that may well control the system.
The reasons may also include strange internet connection speed or increased traffic.
The reason that someone else has gained access to your server may be:
Inappropriate VDS server software form;
Weak or lost root passwords;
Lack of software updates;
What to do if hacked?
Check the site for vulnerabilities and viruses. It is very important when working with servers - constantly update the site scripts and packages. Monitor the performance and log files of the vds server;
See what files were recently modified.
Check your mail queue for spam. To find the script that does the mailing, enter the command X-PHP-Script in the search bar;
Check the files in the temporary and boot directories. Often, scripts that should not be allowed into temporary folders are the source of the problem;
Check for shells. If you find codes, delete them immediately.
Check if the software is updated.
Problem - found. So how to restore the functionality of the vds-server?
Sometimes, just restarting the system is enough, but it does not always work. If you were able to find the exact problem, then use the following steps:
Set restrictions for individual IPs to the panel;
In Firewall, close panels you don't need;
Run SSH key and password update;
Perform a software update;
Get rid of unknown scripts.
It is also important to follow some recommendations that will help protect your server from being hacked:
It is necessary to have constantly created copies of files;
The file access addresses must be changed;
Access to the server should be allowed only from your IP;
Update scripts after updates;
Change passwords periodically and use non-standard logins;
Use official resources. Especially when downloading the necessary software;
Hackers are quite professional in terms of taking over other people's servers. Therefore, it is necessary to take the security of vds servers very seriously. Everything written above will help you avoid hacking and protect your own server.
