Bad web servers
Disadvantages in SEO
Viruses and Trojans
A few simple rules will help prevent your Joomla site from being hacked. This includes always updating Joomla on time and using strong passwords. Also, access data should not be spread too much, passwords should not be stored on the computer and an htacces protection for the Joomla backend should be created. In the following two links, which show impressively what can happen if you don't maintain your pages.
If your site has been hacked, it must be shut down immediately. Most of the time the page is already blocked by the web host. However, there are also web hosters who do not recognize a hacked website and thus cause far greater damage. The actual security check only starts after the shutdown.
A security analysis includes checking the web server, installed extensions and log files. Due to years of experience we can give a quick assessment and localize the virus quickly.
We offer special tools that search your site for certain code components. This will report base64 or hexadecimal lines of code as suspicious. We then go through the entire list of files found and analyze them. Any file found to be corrupt is removed.
Most of the security holes are in outdated extensions and in Joomla. We are updating these extensions, so that at least the security holes in the extensions are closed. Joomla is also updated.
Webserver & access data
If a current and clean Joomla installation is hacked, this may be due to the web server and the used Apache, PHP or MySQL version is outdated. Possibly problems on operating system level can also lead to hacks. Badly configured servers can be a problem. Often passwords that are too weak and trojans on computers are also a major weakness that leads to hacking of your site. For example, FTP data is tapped by Trojans and the malicious files are loaded directly onto the server. With such problems, even the most secure CMS cannot prevent a hack.
As with many providers, there are better and worse web hosting companies. There are many reasons to consider changing your web host. For one, it is always advisable to change if the performance is fundamentally wrong and is characterized by poor support, poor performance and poor technology. Some webhosters cannot keep up with the growth and demands of the companies and fall by the wayside. Another reason could be the web host's lack of innovation. Partly one notices also after a conclusion of the contract that the web space in this form is not suitable for complex CMS like Joomla. Also here you can profit from our experience as Joomla agency, since we know most webhosters. We will gladly help you with the move to a new webhoster.
