Shared Hosting Security Issue: Protect Websites from Hackers

securityFor its affordability and usability, shared hosting is widely used by webmasters and small business owners. However, compared to the advanced virtual private server or dedicated server hosting, shared hosting comes with low security level.

With shared hosting, hosting providers take responsible for the server management and security. Sometimes, providers will make decisions to protect hundreds even thousands of accounts on the same server, but their decisions might influence some people’s hosting environment.

If their websites are hosted or function as a part of shared hosting environment, people need to take measures to protect their websites from hackers. In this article, we give people some useful tips.

Maintain Websites Clean and Clear

Usually, hackers love to take benefits from the out-dated scripts that website owners may have forgotten. If scripts are not being used on people’s websites, just remove them. In addition to scripts, FTP accounts, email accounts and other unused files and unneeded applications should also be removed immediately. Maintain websites clean and clear will not help protect websites from hackers, but also make backup take shorter.

Regular Backup

Although hosting providers claim that they will make regular backup for customers, people should not rely on these services to protect their information, files and websites. People can use hosting providers’ backup as a fail-safe measure, but on the other hand, they have to create and make regular backup their own. Nowadays, there are many simple and useful backup tools available to make the backup progress quite easy and convenient.

File Permissions

People create websites, present them to the public and also let visitors leave comments or engage in other interactions, however, there are multiple private areas on their websites that cannot be accessible to the public. Actually, 7-7-7 file setting is a kind of invitation to hackers to access websites, so people need to make sure their permissions for read-only files are set properly.

To maintain effective and proper operation, content management systems may require specific permissions. People need to change the permission carefully, just in case, they can take note of the current permission. People might change a permission that they should not have, once their websites stop functioning or running.

Strong Password Protection

Many people like to use the same password on different accounts like FTP accounts, MySQL database access, installation or etc. In the situation, if hackers gain access to one of the password, then they can rapidly damage the whole websites. Avoid using common words or phrases as passwords, and strong password usually consists of numbers, letters and symbols.

If people use content management system like Drupal, Joomla or LMS, password will also protect the web address for the administrator login. This helps enhance security level, and make it is harder for hackers to identify which application and software is running on server.

Update Applications

Application providers and developers will work to make improvements. No matter what software and applications people are using on their websites, they need to subscribe to the updates and security releases. Auto-installer’s push notification may be delayed, it is necessary for people to learn how to perform upgrades on their own. Update applications will help protect websites from security vulnerabilities and also prevent hackers from taking advantages of those out-of-date applications and software.

Java Applications

As the result, it also exposes users’ computer information to those knowledgeable and experienced hackers. One of the most effective ways to protect websites from hackers and increase security level of a shared server is to reduce the possibility by offering access to special features only to registered users.

Turn On Safe Mode

PHP scripts allow people to access information on a shared hosting environment. It is possible to run a script that lists all of sensitive information of websites, like files, passwords and etc. Turn on Safe-Mode enable to prevent the ability for non-authorized users to execute scripts offers a level of protection. If people have no idea about this, they can request assistance from their shared hosting providers.

Use Databases to Store Sensitive Information

Instead of storing information in files on websites, we strongly suggest people to store sensitive information and protect websites from hackers by using databases. Fortunately, with most applications and software, the database is used automatically. And some others, they offer people an option between the database or server hard drive to store information.

Computer Protection

There are some viruses and malware are designed and developed to exploit FTP programs and gain access to people’s files on their websites. If people’s computers are unprotected, then their FTP programs can be easily compromised. So, it is necessary to strength computer protection by installing those reputable and reliable antivirus programs and software.
