The Importance of Dedicated Server Security

Having an on-line presence is an essential requirement for mostly all types of businesses. Reaching out to the largest and most varied market available, being on-line with a company website can be very rewarding to your business. It also faces security risks just like with any office premises in the real world.

Security should never be overlooked; it is quite easy to sometimes ignore proper security practises to save time and effort. Although ignoring essential security practises could severely affect your business later on, as more web traffic is driven to your website and your user base grows.

Forms and scripts could enable users to interact with back-end databases in a typical dedicated server setup. Securing these forms to ensure any invalid characters are removed during the processing stage is an important step to think about during the website development even before the website is deployed onto the dedicated hosting server. Any elements of the website that allow the user to interact with the dedicated server should be tested and researched for proper security practises.

Another important security measure to think about is directory and file permissions, file permissions is often overlooked when deploying applications that run on a dedicated server. Developers can be easily be drawn to overlook applying the correct permissions to ensure the application works without any access problems with files on the server. Correct permissions is very important as any users that have some form of access to the server could potentially execute, read, and write to a file they are not suppose to. Be aware of 777 permission, as this would leave a file to be accessed by anyone and is never recommended.

The operating system on a dedicated server should always be updated to ensure is has the latest updates of the operating system. The foundation of any dedicated server is the operating system and hackers are constantly finding new methods to gain unauthorised access. This could be through exploiting software installed on the dedicated server or additional software added that opens ports to communicate with external users.

An additional level of security is also an essential requirement for any business which relies on its web presence. There are systems such as firewalls, intrusion detection systems, port monitoring services, and anti-virus/spam software which helps detect and remove any possible threats.

Physical security to the data centre is also important and should not be overlooked.
