It’s not fun to go through your server and close every opening that a malicious web user can take advantage of. Nevertheless, it is completely necessary to keep your web site running and free of harm. To get started, you should be open your control panel and forage around your options menu.
Any time you give someone access to your dedicated server, you are allowing one more way into your secure information. Even if the person is trusted, things such as social engineering can pry passwords away from someone quite surprisingly. Essentially you want to limit anyone who has access to not only your server, but to any serve your server offers to others.
A server straight out of the box will be near useless to you. If you want to provide your back end and the front end functionality, you will have to install modules. Modules are small scripts and programs that allow you to do things such as use a language or program to run your server. Update are frequent, and should be downloaded to avoid certain security risks.
Not only can your back end create security problems, but so too can the languages you use to code your website. Languages today are very popular. A language like MySQL will allow you to delete an entire table without warning with a simple command, so long as a user has authority to run it. Protecting your passwords and securing any methods of things such as SQL injection is dire.
Any services you are not using should be disabled promptly. Sometimes your server will come with ports and programs running that you not only don’t need, but won’t be monitoring as a result. Telnet is an example of a service that few have a real need for, and can be used to gain entry into a server. Find out how to change and close ports to avoid destruction that could be otherwise avoided with a few minutes of time.
Server administrators always make backups from time to time. And this just isn’t because of bad users that want to ruin your server for fun- it’s because sometimes there are bugs in code, accidents, and other odd happenings that can’t be explained. If solutions don’t seem to work out, having a back up is always something that can be done as a last resort- and they are easy to do as well.
